Phenol, bacteria, Consett Coke ovens


An example from my personal experience: At Consett Coke Ovens one of the waste streams was phenolic liquor. Once-upon-a-time it would have been dumped down a disused mineshaft! We treated it in an activated sludge plant (loads of bacteria). Pretty amazing that it worked at all considering that the old name for phenol is carbolic acid and it’s a disinfectant which kills just about anything. We had a “spike” in phenol concentration (the plant was old, some of the processes had problems and the control systems were partly f*cked). As a consequence the bacteria “went to sleep”. They weren’t actually dead, but they weren’t active. As a consequence, even after the phenol levels returned to normal, the activated sludge plant no longer worked. We couldn’t treat the phenolic liquor, we weren’t allowed to dump it and we had only limited storage capacity. In these circumstances the official solution was to get a tanker load of sludge full of adapted bacteria from another coke plant. The nearest one with a suitable plant was in Sheffield (probably Orgreave). Cost at the time – several hundred quid. We chose the cheapskate option: buy a lorry-load of steaming, fermenting farm-yard manure and dump it in the sludge tank. Cost – 50 quid. After a short time (not more than weeks, and within the limits of the buffer storage capacity) the activated sludge plant was back and operating to specification. BTW on that plant they described having too much liquor as being “embarrassed” – as in “an embarrassment of riches”. A nice turn of phrase, with a touch of irony - “an embarrassment of sh1te”.

I doubt there are bacteria in nature which actively use phenol as a food source. Thankfully there isn’t enough of it around. There are undoubtedly bacteria which can tolerate phenol up to a certain concentration. The moral of the tale is that given the opportunity, within a very short time, bacteria can adapt to use something which is an outright poison to them (phenol) and not simply tolerate it, but use it as a food source. How they do it is not clear to me, but they certainly do. That is amazing and scary! The rubbish-dump programme was another example of the same.

The messenger (6) Anticipation (ABCD)

The messenger (6) Anticipation (ABCD)

All 4 of the crew are sitting in the control room. Andy and Beatrice have been there for some time. Charlotte and Dave have just come in. Andy is sitting at the main control console facing the main control screen. Beatrice is sitting at the sensor monitoring console to one side. Charlotte and Dave are sitting towards the back of the control room with Beatrice and have turned towards the main screen. The atmosphere is tense as they await the arrival of the visitor.

C: “How long do we have to wait?”
B: “Not you too!” With a smile, “I’ve just been chastising Andy for asking – Are we there yet? You’ve both arrived just in time. There are about 10 minutes to go. Our visitor is very nearly dead astern, as they say. It will appear to draw alongside and come to a halt. Of course we are all hurtling towards the centre of the solar system at the usual phenomenal speeds but the two objects will be stationary to one-another. Even after all this time, I find the mathematics easy but the actuality continues to surprise me. ”

D: “Is there anything much to see yet?”
B: “Not a lot. It’ll all happen a bit suddenly. Because of the end on approach, the relative velocities at the moment and the relatively small profile of the object, it will start off as a disk which will grow in size until it resolves into a long thin object. When there is something worth seeing, with Andy’s permission, I’ll stick it up on the main screen. It won’t be long now. ”
A: “Anybody care to guess what we’ve got?”
C: “Probably a valueless lump of Ice which just happens to be a funny shape. Mind you, if that is what it is, then the shape takes a little bit of explaining.”
D: “Well, I’m going to be optimistic and say that we have a lump with lots of juicy nickel and a sprinkling of precious metals. The shape is because it got squirted out of some explosion.”
A: “That’s a good explanation. Despite all the teasing, I really can’t believe it’s an alien artefact. Those things just don’t happen outside of entertainment. Come to think of it, aliens aren’t really that popular as entertainment at the moment. I think I’ll go for an agglomeration of ice, rock and metals. What about you Beatrice?”
B: “I’m not speculating any more. I’ve seen too much. It would be cheating if I said too much. Take a look at this.” The image on the main viewing screen changes, in the centre is a small white dot. The image is surrounded by a red circle and there are target arrows pointing inwards.
C: “Is that it then? Is the little dot in the middle our visitor?”
D: ”It seems to be twinkling? ” interjected Dave.
B: “Yup. Whatever it is, that’s it. And the ‘twinkling’ which Dave has noticed is one of the things which make me think that it is rotating. There are some other interesting features too.” A table of figures flashed in the bottom of the screen.
“One of the things I find interesting is its albedo. It’s really quite bright. Unfortunately, that might suggest that it’s got a lot of ice on the surface. The twinkling might be caused by a patch of discoloration on the face towards us. As the object rotates, so the colour moves and we see a twinkle. It’s a bit like a spot in the centre of an old-fashioned vinyl record. Also there is a hint of some irregularity further back. Our visitor isn’t a perfect cylinder, that’s for sure. Any bumps may be contributing to the effect. “
D: “It gets full marks for interesting. Have you got an estimate on the rate of rotation?”
B: “That is one little disappointment. The estimate is pretty much the same: one revolution every 5 or 6 minutes. Maybe it’s the lumps, or maybe it’s something else, I really don’t know. What I do know is that we’ll know shortly when it’s alongside. There’s nothing much we can do now. The systems will take care of it all. There’s no risk. Let’s settle down and watch the show. Has anyone bought the pop-corn?”


With that, everyone turns to look at the main screen and the changing disk in the centre of the field of view.

The messenger (5) Playing Catch-up (AB)

The messenger (5) Playing Catch-up (AB)

Andy and Beatrice are sitting in the control room. It’s not a large space. There are 3 seats in front of a console. Andy is sitting in one of these seats and is looking intently at a monitor screen ahead of the console. It shows what appears to be a stationary star-field.
A short distance behind Andy there is a group of 4 more seats. 3 of these are facing inwards towards the centre-line of the control room. Beatrice is occupying the fourth seat. She has swivelled it round and is looking intently at a smaller monitor screen on a panel in front of her.
A: “How’s it going?”
B: “I was almost expecting you to ask – are we there yet?” She smiled. “It’s coming. It will be long-side of us in about 45 minutes.”
A: “I hope I didn’t sound like I was nagging. I want to see this thing in the flesh, or ice or iron or whatever-the-heck it is.”
B: “It’s alright. I really do understand. If we are wasting our time then I would like to know as soon as possible, so that we can get back to the daily grind. If it’s a money-making opportunity then I would like to be doing something about it too.”
A: “And if it’s little green men?” (with a smile)
B: “You and your little green men. If it’s little green men, or even something which hints at little green men, then I want to know yesterday! If it’s that, then doesn’t matter what else, we’re famous. But of course it’s not. How can it be? There are plenty of strange things out here, without them being caused by aliens. You know. We’ve seen enough of them together.”
A: “Well, what does it look like then?”
B: “If I’m going to be honest, and I should be. I’m still not sure. Whatever it is, it doesn’t play too nicely with our various sensors at this range. I can tell you that it’s about one-point-two kilometres long. It’s about 100 metres wide. It seems to be a very regular long shape. I can tell you its mass within a few 100 kgs. That was actually the first thing we knew with any accuracy. As for density, it’s too dense for a typical snowball, more like solid water ice, but certainly not dense enough for solid metal.”
A: “But have you any idea what it looks like?”
B: “No. And in a way that is the puzzling bit. I can tell that it is rotating. It’s not tumbling mind you. It’s rotating about its longitudinal axis. It certainly isn’t tumbling. But for some reason the Doppler isn’t giving a clear estimate of the rate of rotation. That might be because it has a bright albedo, or to put it another way, it’s rather shiny.”
A: “Shiny, as in – like a lump of ice?”
B: “Exactly. That’s what I was thinking too. If it is, then it’s a really funny lump of ice!”
A: “Anyway, when to we get to see this marvel?”
B: “It will be clearly visible in about half an hour and then be alongside us about 15 minutes after that. It will seem to be overtaking us, pull alongside and then come to a halt. It’s all to do with the relative velocities, but it always strikes me as a bit strange. Should I call the others? I don’t suppose they want to miss the big event of the trip.”
The door at the back of the control room opens. Beatrice turns to one side and Andy turns round in his seat.
A: “Hello there. We were just talking about you both. Beatrice says that the show is about to start. Pull up a chair and make yourselves at home.”
Charlotte and Dave take the front seats in the group of four and turn towards the front viewing screen.

This represents an experiment in method. This is what I am doing/going to do/have done:
  • Brainstorm a topic and location for the "Chapter":
  • List a number of topics, in sequence to be covered
  • Based only on the line item, write (stream of consciousness) for a topic
  • Link the topic from the list when it is done
  • Conclude the chapter
Let's see how it works as a creative process.

The messenger (4) Board Meeting (ABCD)

The messenger (4) Board Meeting (ABCD)

The four of them: Andy, Beatrice, Charlotte and Dave are sitting around the table in the mess-room. Each of them had a drink in front of them. Andy and Beatrice are reading reports on their slates. Charlotte and Dave are sitting back exchanging glances from time to time. Eventually, Andy and Beatrice both look up and put their slates down. Beatrice takes a sip from her cup.

D: Dave coughs and looks around the table. “First of all, I’d better apologise for getting you out of bed. And thank-you Charlotte for staying back. It’s a nuisance.” He pauses. “The whole situation is a nuisance. We’ve probably all been wishing for a bit of variety, but probably not like this. You can see the picture which has been building up over the last day-and-a-bit. Probably from Andy onwards you know more about the situation than I do. It happens that the decision point seems to have fallen on my watch.”
A: (With a yawn) “We understand. Really we do. “When I first noticed the anomalies I didn’t pay much attention to them. They were just a bit or variety. But now they seem to have crossed the line of us needing to take some action.”
B: “Yes. We understand. The sensor problem is just on the margin of being acceptable, but it looks like it has continued to grow.” She indicated her slate without picking it up. “It’s at the point where, even if it was an isolated problem, the Officer of the watch should notify Head Office.”
C: “So you think I did the right thing?”
B: “Definitely. Even as an isolated situation it justifies a report and, just possibly, extending our scheduled stop at Ceres.”
D: “Do you think that’s justified?”
B: “At present, probably not. But certainly worth noting HO and when combined with the incoming visitor, definitely worth the notification. On its own the sensor problem, meetings the criteria for logging as a low level risk. It would be different if we knew what was causing it, but we don’t and it’s getting worse, so we notify HO, even if only to cover ourselves. Personally, I think the risk is tiny, but that’s not the point. The rules say we notify, so we notify.”
A: “And what about the visitor?”
C: “That’s different. From the investigations that Beatrice and I have done, it looks like it could be pure opportunity. If we put in a course alteration at the point I’ve indicated, then we can rendezvous and stake a claim. Nice big lump of nickel-iron will do the bank balance no harm at all.”
A: “And what about the other features of our visitor?”
C: “You mean long-thin and rotating?”
A: “Yeah. It’s long, thin and possibly rotating. Those combined with your density estimate mean that we have to notify HO. But what do you think?”
C: (with a smile) “I think you and Head Office have got little green men on the brain. People have been mining out here for the past 50 years. A few people have struck it lucky with visitors but very few, and nobody has found anything even remotely like an alien, green or any other colour for that matter. If we’re lucky we’ve got a lump of iron with holes in it. That’s worth the effort. If we’re unlucky, then it’s a big lump of ice with a funny shape and we’re wasting our time. I think it’s worth a look but that’s all. Head Office wouldn’t expect us to do anything different. They like money too, and they’re not taking any risks.”

D: “So, what do people think? Shall we divert and go and have a look at it? For what it’s worth, I don’t feel particularly lucky at the moment but if the rest of you fancy the trip then I’ll go along with you. It will mess up our pub night and the call at Ceres though, to say nothing of having double up.”
Dave looks around the table. Charlotte and Beatrice nod vigorously and Andy gives a thumbs-up.
D: “OK. That’s a decision then.” He picks up his slate and makes some notes on the screen. “I’ll log the decision and notify HO that we’re diverting to have a look at our visitor.”
B: “I’ll put the wine for the pub night on hold. It could probably do with a bit more maturing anyway.”
D: “I’ll go and program in the course change.”
B: “I’ll set the sensor arrays to give our visitor even more attention. Let’s hope the white noise blips don’t get in the way too much.”

Everyone leaves the mess-room.

The messenger (3) Shift Change 3 (C - D)

The messenger (3) Shift Change 3 (C - D)

Dave sat at the galley table sipping a mug of strong black coffee. He had placed a glass of orange juice in front of the seat opposite him. Between sips he looked intently at pages on his slate, sometimes scanning back to revisit earlier pages. He was surprised that Charlotte was late, that’s not like her at all, and he was puzzled by some of the notes she had added to the shift log.

The door opens and Charlotte rushed in. She is a little flushed and seems to have been hurrying.

C: “Sorry I’m late. Something has come up which I think you will want to look at.” She sips her orange juice.
D: “Is it urgent, as in ‘we do it ahead of the standard hand-over’?” said Dave looking at her intently. He’s a big man with a florid, craggy face.  His long hair is combed back into a ponytail.
C: “No. It’s not that urgent. But I think it is important. I may be wrong, but I think we may have to call the others in on this. Let’s do the standard hand-over and then talk about it.”
D: “What! Get them out of bed? Andy won’t be pleased about that. OK. Let’s do the hand-over.”
For the next 5 minutes Charlotte and Dave got through the report pages on the slates. Both were a little impatient and both wanted to get to the end of the standard hand-over so they could deal with the important issue that Charlotte is excited about. Eventually they got to the end.
C: “Now we get to the important points.”

Dave leant forward.
C: “You’ll be aware that nearly a day ago the systems drew Andy’s attention to two issues: an internal issue, that there was periodic interference on the main sensor array; and an external issue, that we had an incoming object which has a trajectory which will cross ours in a little over a day from now.”

D: Dave nodded and said: “Yes, I know about those. Something to keep us all occupied. I was a little disappointed that both things had come along a once.”

C: “You may not be disappointed for much longer. Andy worked out a plan for dealing with tackling the incoming object. Basically, if we were going to intercept it here” She indicated the appropriate point on the slate’s chart, ”then we would have to initiate the manoeuvre here, and that means that if we are going to make do everything by the book, then we would have to make the decision to intercept before here, which is during your watch”
D: Dave nodded: “I understand. So in a way, either the decision about the decision is down to me, or we all get involved.” He paused. “Is there any more information? More than is in the logs, I mean.”
C: “Just a little. Beatrice investigated the problem with the sensor array. She didn’t really establish much, except that the problem seems to be getting worse. That’s worrying. That alone justifies the message she’s sent to head office.” Dave nodded again.
C: “Regarding the incoming object, she also managed to estimate its mass, based on a deflection here. She put together a plan for getting some more data about it, even though it is still well beyond the range of our sensors.”
D: Dave nodded again. “That’s the transit of Neptune idea. Did it work?”
C: Charlotte took a deep breath. “Yes. And that’s the point. The incoming object has become significantly more interesting on three counts.”
D: “Three counts. What are they? You were only trying to estimate the density.”
C: “That’s true, but there are other things I had to find out at the same time. First of all, the density comes out as substantially higher than a snowball. The volume estimate is subject to a pretty big margin of error, because of the way it was calculated. The object is not solid nickel-iron, but it’s could be solid, and I mean solid, water-ice. That’s very unusual. Second,  I had sort-of assumed that the object would be spherical, or at least spheroidal. Look here, it’s very long and thin. The length to width ratio is more than 12. It’s very long and thin. And finally, three, there are indications, based on the way its silhouette changed as it passed in front of Neptune, that it is rotating around the long axis.”
D: Dave exhaled and scratched his chin. “It’s ticking a lot of boxes for alerting head office and investigating, isn’t it?‘’
C: “Afraid so. It’s just a couple of points short of ‘drop everything and investigate’ What do you think?”

D: ”Getting people out of bed or not, I think it’s time to call a meeting.”

Letter from an Island in Winter

(I'm having a clear out. I want to retain the text of this and remove it from my hard-drive at the same time. It has been redacted to give people a little privacy. If you know, then filling in the details is easy enough. It was originally written on 23rd November 2012)
Xxxxxxx,
Isle of Xxxxxxx
Argyll
Scotland
23rd November 2012
Dear Aaaaa,
                It’s a different address at the top. I’m up here for a week “chilling”. That’s chilling in both senses of the word! It’s beautiful but my goodness it can be cold.

                I’m staying with my cousin Qqqqq. “Xxxxxxx” is the name of the house where she lives, out in the wilds. It’s pronounced (locally,  so I suppose that must be right) “Cairn-na-xxxxx”. The first bit is obvious enough “Pile of stones of…” but nobody is sure what the rest means. The commonest explanation is that it is “xxxxx’s Cairn”, that fits the pronunciation, but not the spelling, and there is no known association of “xxxxx” with the island. There is general agreement that whatever the name is, it is a slamming together of Gaelic “Cairn-na-” and something else, probably from another language, and that could be English, Scots or Norse.  It’s one of life’s puzzles, and likely to remain so.

                Whatever it’s called, the view from the place is spectacular, in every direction: East and West I can see the sea, North and South Rocky hills. To the west is the island of Mmmm, very mountainous and to the east Kkkk.

                I don’t know whether I shall get this finished, printed and posted before I leave the island, but you will know by looking at the stamp: if it is UK, then it was posted in Scotland; if it is Irish then the letter came back to Ireland with me and was posted there.

                Like I said, I’m up here “chilling”.  I felt like a trip up here to see the relatives, and Qqqqq was happy to have me. She works at a poultry (egg) farm on the mainland. She gets a ferry at around 8 in the morning, drives 10 miles to work and then returns in the evening and gets home a little after 6. She has a car on the mainland and one here. It’s a long day and if the weather delays here on the island she can lose hours (or even a whole day’s pay). I haven’t asked her what will happen if she gets stranded on the mainland, and I’m not going to. It’s certainly not an easy life for a single woman. During the day I am left of my own devices. This is the house which Qqqqq was brought up in, and I can see the Farm which my Grandfather took out a lease on in 1916 (!), so you can see that the family connection with the area is pretty strong. The house is constructed from two stone buildings (one the original house, one a stone barn) joined together by a wooden “covered way” in an “H” shape. The house could really do with some serious maintenance. It isn’t falling down, but it is cold, draughty and damp. Qqqqq does a good job keeping the place clean, tidy and homely, but it must be a struggle. In the house end, the living room and the downstairs bedroom where Qqqqq sleeps are nice (although you have to think about how to keep the places you want to be at the right temperature). The kitchen is an ice-box, and the two bedrooms upstairs have been relegated to attics (even the electrics have been stripped out, and the stairs up there have been covered  at landing level to  keep downstairs warmer). In the barn end, where I sleep, only one of the 3 bedrooms is habitable (and is actually quite nice, if chilly). The bathroom is usable but…

 The work required on the house is real “building”, rather than the DIY and decorating which I’m up to. Qqqqq doesn’t have the money and the island Trust, which is her landlord doesn’t either, so she will just have to wait for things to improve. I had hoped to do a little maintenance work for her, but as it happens things weren’t ready so I’ve been excused that. I’m sorry, and not sorry at the same time. Sorry the work won’t be done (and I would probably have enjoyed doing it), but not sorry that I don’t have to mess about outside in the weather.

If the house was mine, and I had unlimited budget, I would give it a complete refurbishment. Probably hire Kevin McCloud as a consultant and find a local architect. It would make a good Grand Designs. I think the approach I would take is to re-furb each of the stone buildings in turn and then completely replace the covered way with something of similar appearance, but different construction. Given where it is, I would emphasise weather-proofing, insulation and self-sufficiency. The south facing roofs of the stone buildings are not visible from the road, so that gives scope for solar water heating and photovoltaic cells. We’re half-way up a hill, on an island, so a wind-turbine is an obvious possibility. Water is never going to be a problem! The end result would look very similar to way it does now. At the barn end, the ceiling height of the rooms is really way too high. Also the existing internal walls are all stud-work, so I would regard that as completely disposable. There is a wooden floor which I expect was used for levelling, but it isn’t great quality. I would take advice from an architect and consider lowering the ceiling height and creating more bedrooms upstairs. So, at present the house (both bits) has a total of 6 bedrooms, of which only 2 are really habitable. The others I would only give to real hard cases who had arctic, four-seasons sleeping bags and camp beds. I think there is potential for 9 to 12 bedrooms etc. It’s never going to happen that way, but I certainly enjoyed writing about it. Qqqqq has dreams of having a B and B here. The house just isn’t acceptable at the present (except to afore-mentioned hard-cases, and I suppose I may be included among them), but I hope she gets to something like it in the end. She deserves it.

(And it’s 13:35, and there’s the afternoon ferry to Yyyyyy in Xxxx passing)

Meanwhile back in Ireland,  Ssssss and Mmmm are doing “work experience” the week I’m away. Ssssss is helping out at the Infant’s school down in the town. On the day I left, she had drawn a giraffe on the wall (the giraffe is holding a measuring tape for “how tall am I”). Mmmm is at the garden centre across the road. So far, she has been watering plants in poly-tunnels and has learned how to operate the till. Ironically, I’ve been involved in creating two point-of-sale systems, but I’m not sure I could operate a shop till! Nnnnn is still working at the school. She seems to be endlessly marking books. They’re all fit and well and I hope they are feeding properly. They should be,  I left the fridge well stocked.

One of the things I’m doing while I’m away in Scotland is writing up a “business plan” for something over in Ireland. I have to confess I’m struggling, but it’s getting done. This is a good place to work. I may push the “go” button this month (for a January start).

As usual, I’ve included some clippings from the local papers:
David Bowie – Has continued to rise in my estimation: weird? yes, but undoubtedly creative and influential. It seems he may have decided to retire, or is this just another “stage persona”?
The Rolling Stones – They’re a good blues band, but I always said Jagger was more of an accountant than a rock star.
Curative Well – Well, what does one say? I hope they didn’t ever dose you with lithium. I always thought that lithium was more of a sedative and anti-psychotic, but maybe it has anti-depressant properties as well. By the way “TG4” is the Irish Language channel.
Fearless Felix -  What does one say? The kind of thing he does only goes wrong once.
Sulky Racing (*2) – What does one say?

Regards,



Old Boar

Education: Blaming the tools when it all goes wrong

Education: Blaming the tools when it all goes wrong

(This is the text of a 9,062 word essay which I shared with an acquaintance on 23rd May 2017. I'm having a clear out and disposing of the source material. I wanted to keep the final version. The text contains spelling, formatting and content errors and has been redacted)  

There is no such thing as bad weather, only poor clothing!
Scandinavian Proverb

Introduction

The perceived problems with education are a reflection of the problems with wider society. Education is part of the solution, but it would be a mistake to try to fix “education” in isolation.

A lot of the problems are that society is not sure what it wants “education” to achieve. Formal education is given too many, inconsistent and conflicting requirements.

The result – we finish up wearing the wrong clothing for the prevailing weather conditions.

Summary

This is way too long. A classic case of “I didn’t have time to write a short letter, so I wrote a long one instead.”

I look at:
·         What we want from education,
·         How education might work in a simple society
·         What constraints do we have?
·         How do we “do education”?
·         Who are the “stakeholders” in education?
·         The problem of measurement
·         Some discussion
·         There are some good links at the end.

This is really a review, and some rambling discussion, rather than a carefully argued proposal. Education seems to give rise to these paradoxes!

What is “Education” for?

For this section I’m going to use a loose definition of “Education” which encompasses formal Education, from kindergarten to university, your Open University course, Evening Classes, what I dish out through Udemy, and the mass of other “personal development” activity which people undertake. I think that “learning” is a better term to describe the process, because “Education” tends to be used to imply something formal, performed in an institution, but more of that later.

The way I see it, “Education” (especially the formal kind) fulfils a number of roles. Not all these roles are comfortable to accept, but I think they are all real. These are “what Education is for”. Misunderstanding what people want “Education to do” is a sure way to end up with being dissatisfied with what “Education actually does”.

Here are the things which I think different bits of society (“Stakeholders” if you insist) expect Education to do:
·         Child-minding, Keeping them of the streets and safe from harm – Often overlooked, but this is a genuine expectation. This is most obvious from kindergarten to the end of secondary school. You could argue it happens at University too. It ceases only when the subject is truly considered to be an independent, responsible adult. On this basis, some university dons never really graduate!
·         Socialisation: Freemasonry uses a chisel as a metaphor for Education and says:
“The Chisel points out to us the advantages of education, by which means alone we are rendered fit members of regularly organised Society.” (my emphasis)
It’s difficult to date this precisely, but it is 17th to 18th Century, so this belief or purpose has been recognised for a long while. At its most basic this is potty training, “sitting still” and “taking turns”. It’s a genuine objective. You also get “rebellion”, but even rebellion is against the norm. Rebels have to rebel against something. To be a non-conformist, there needs to be something which represents conformity!
Socialisation also involves learning how society expects people to interact together. That makes it “slippery” because different societies have different expectations and any one society’s expectations change over time.
·         Learning Enabling Principles – This is one of the things which probably generally recognised as an objective of formal education. This is theory. This is generalities and generalisation. This is reading and writing and ‘rithmatic (but apparently not spolling!) and grammar.
·         Performing Tasks – This is literally doing stuff. This is applying the “principles” to “practice” and learning how to perform the task to an acceptable standard. This is reading-a-book and doing-a-sum. Some people will make the distinction here between “Education” and “Training”. I recognise that, but the distinction I am trying to make is a little different.

I came across a German saying which sums this up:
“Theory is when you know everything, but nothing works. Reality is when everything works, but you don’t know why!”
I’m not sure “reality” or “everything works” are quite right, but there is a little wisdom there: there is a state of being when things are working (or not working) to a particular level of success, but you really don’t have a theory why.

Learning Principles and Performing Tasks need to be mutually supportive. You can understand the principles and not be competent to perform the task. You can perform the task and not understand the principles. This is most obvious with activities which have a physical or manual component. Sailing a boat can involve theory (however it is expressed) and practice.

Usually to become a true “master” you need to have a theoretical component. You certainly need a theory to move competence to a slightly different task, or to consider changing how a task is to be performed.
·         Entertainment! Yes! Really! People undergo education in order to be entertained. The do it because they like it. By “entertained” here I mean to experience a sense of achievement and satisfaction. This is what all self-improvement is about

I don’t claim that his is a complete list, but it does indicate the broad range of things that we expect Education to do for us.

Education for a “Hunter-Gatherer”

To test some of my suggestions, let’s look at them in the context of a “Hunter-Gatherer” community. Surely there is very little “Education” going on? Actually, I think there is rather a lot of education happening, and some of it is fairly formal, involving formal roles too.

·         Child Minding – Without getting into a “sexism” and Feminist argument, if you are a hunter-gatherer, looking after very small children is a job for their Mothers, but once they are weaned the situation changes. Looking after two toddlers is hard work, but it is not twice as hard as looking after one, and it does not take the full capabilities of an adult.
·         I expect that in many hunter-gatherer communities the “child-minding” role is specialised and delegated to older children, especially the girls, or the elderly. This has multiple benefits: one girl can “mind” several children, it promotes social cohesion between the families involved, it releases the Mother to go out “gathering”, while Father is out “hunting” (or hanging around doing nothing), and finally the “minding” task has the effect of educating/training those performing it about how to do “parenting”.
·         Socialisation – The socialisation aspect of education is undertaken by the entire community. Children are put into the care of their youthful teachers for the daytime, and that is part of the socialisation process for the teachers (and is part of the socialisation of the teachers too). Responsibility (for the teachers) and delegation (for the parents) are useful lessons. If learned properly, then these lessons will increase the cohesion of the society as a group (whatever form that society takes).
At other times of the day younger children may be cared for by their grandparents and even other older members of the community. Remember a hunter-gatherer community is probably only a few extended families. In an odd way, caring for the young and Education may overlap with caring for the elderly. Granddad may be ga-ga, but he still tells gripping ghost stories (which just happen to have an educational content).
·         Learning Principles – In the hunter-gatherer community the “teaching of principles” is one of the jobs of the older folk. This is Granny or Granddad telling the children stories. Many of the stories will have no purpose at all, other than entertainment, but others will be teaching “principles”. In many cases the principles will be encoded as some sort of metaphor or parable and the storyteller himself may simply be repeating a popular tale without understanding it.
Learning principles is also done by structured demonstrations. This is how you choose a particular piece of flint and the justification for the choice is that “the flint demon” (or whatever) likes this particular colour.
·         Performing Tasks – In the hunter gatherer community learning to perform tasks is done by copying other people. At first the copying is done in safe environment, inside the community but difficulty of the task increases, as does the degree of independence in performing it. Children copy their parents and older children. The children copy “The Elders” too, in fact, everyone copies everyone to a greater or lesser extent.
·         Entertainment – Everyone sits down to listen to the stories. Even the best hunter and the head man listen to the storyteller and take turns to tell stories themselves. The same goes for music and dancing. The boundary between the audience and the performers is blurred. There are boundaries between different social groups but they are flexible. Children are encouraged to watch, to participate, maybe even to lead as seems appropriate.

The picture I am painting may sound like a sort-of Socialist utopia. I don’t mean it that way. The society I am describing may be highly structured and highly unequal. For all I know “the elite” may spend all day taking recreational drugs, indulging in deviant sexual practices and contributing little actively to society. No doubt “the elite” will also try to adjust the structure of society in ways which benefit them.

I The key points I take away from this scenario are that for the hunter-gatherers:
·         “The society as a whole” and everyone within it feels some involvement and responsibility in bringing up (educating) the children. Even “the elite” are involved, even if it is only telling stories or leading ceremonies.
·         Whatever methods they use, they feel that if it fails, they will all suffer, if it succeeds, then they will all benefit. They all feel that “they are in the same boat”. There is no escape either. Even “the elite” feel that if they mess up the raising of the young ones (even their own young ones) too much then society will fall and their elite position will not save them.
·         Education is not something that happens in a single place and at a certain age.
·         Educating is not the sole responsibility of a certain class, though there may be specialists, especially those who cannot contribute to society in other ways (like the older children and the elderly).

Constraints and limitations

Education does not take place in a vacuum. I’ve already addressed the expectations that people (whoever they are) may have of it but there are also what I think I will label as “Constraints or limitations”.

By “Constraints and limitations” I mean things which limit how much we “Education” we do, and how we do it.
·         Availability of Resources – This is probably the single biggest limitation. If we cannot afford it, then we won’t do it. Education (and other child-caring) and caring for the elderly are probably among the ways that society “takes-up the slack”. If we use the example of the hunter-gatherers, then if there is a famine, then education may become a low priority. The child-carers may be released from their duties to gather food or hunt, or the whole community may “up sticks” and migrate, in which case education (and maybe even the children) will become a low priority.
·         Priority given to Education - Although the resources argument has a great deal of power (you can’t spend what you haven’t got), it is noticeable that relatively poor people put a very high value on “education” and it is sometimes seem as a route out of poverty. These are decisions which are taken at both the individual and the collective levels.
People will sacrifice a lot in order that the next generation are better educated. This value placed on education varies from society to society. It is part of the justification for how much we are prepared to “spend” on education.
This “priority” discussion can be extended to how we distribute the resources we spend on education across objectives (Child-minding, Socialisation, Principles, Tasks etc.), social groups and methods. Sometimes the results are surprising: “foreigners” and social climbers may spend an enormous amount of effort on “socialisation” and conforming to the local society, while at the same time expending effort on doing the exact opposite by maintaining a separate social identity.
·         Skill of the teachers – How skilful are the “teachers” you have at your disposal? In this sense I mean “how good are they at teaching?” and also “How good are they at teaching in a particular way?” This is actually quite a tricky question. People can be skilful using particular formats, teaching particular topics to particular audiences. It isn’t simple. You only have to use the counter-example of imagining a university lecturer trying to teach quantum physics to 3-year-olds to realise that if you are going to be successful you have may have to match the topic the teacher and the audience.
·         How knowledgeable are the teachers? – It is a given that you can’t teach something that you don’t know. But on the other hand, you don’t have to be very knowledgeable about something in order to teach it. There are plenty of apocryphal tales about “the teacher being one step ahead of the students” and a lot of people who give instruction for “task” education have very narrow knowledge, but may have lots of experience; think about instructors in the armed forces.
This question of “how knowledgeable” is rather difficult to tackle. It seems obvious that you want knowledgeable people who “know their stuff”, but trying to enforce that as standards, and especially across different topics and for different groups of learners proves to be very hard.
·         Status of the teachers – What sort of status do you want to give your teachers? How much do you want to pay them? How much are you able to pay them?
This proves to be another tricky one. There are real contradictions here, and there are some significant “political” (small “p”, not necessarily party politics) factors too.
Let’s look at who actually does the “teaching”. There is change from kindergarten (almost exclusively female), to university (majority male). There is certainly a case for examining this from a feminist stand-point and asking if this is really what we want society to be doing?
There seems to be a problem with the perception of “teaching”. On the one hand it is described as a “profession”, but on the other, the conditions of employment are really not that good. Part of the issue seems to be that “teaching” is in some cases used as a default occupation where “those who can, do; those who can’t teach”. This results in oversupply of poor quality providers.
Another aspect of this is an over-emphasis on the “child-minding” aspect of education – “keeping them off the streets” (or the unemployment statistics).
·         Efficiency and Effectiveness – You want both, but they are not necessarily the same thing! Let’s take some contrasting, and extreme examples:
o   If we only have one instructor, and we want to “tell” 100 people, then the traditional university lecture may not be very effective, but it is very efficient and at least some of the message will stick.
o   On the other hand, one-to-one coaching is probably the most effective way of teaching many things, but it is woefully efficient and very expensive.
o   The “cellular” approach used in some developing countries can work quite well. Teach some “teachers”. Send them out into the bush to teach their villages. Get them to send their best pupils for more instruction. Keep repeating. Very efficient, but the lessons have to be very simple. You can get a simple message out to a lot of people very quickly. The Communists did this a lot.

·         Aptitude – Aptitude is overlooked in the mainstream education system. Some people start off having potential to be very good at something. The problem is that the only way to really prove if aptitude is there is to give it a go! This suggests that having a standard basic curriculum and then allowing (or even encouraging) digression from it might be a very good approach for finding people with unusual or unexpected aptitude for topics..
·         Motivation – This is another factor which is overlooked in current mainstream education. People need to be motivated in order to do anything.

"He who has a strong enough why can bear almost any how."
Friedrich Nietzsche

Motivation can be positive or negative, “the carrot or the stick” and it can be internal or external. One major difficulty is that what motivates one person may be ineffective or counter-productive with another.

Adults are probably better at providing their own motivation. In fact, it might be argued that one of the objectives of the Education is to teach us how to understand, manage and regulate our own motivation.

We need to consider whether all motivation is a good thing. Can there be such a thing as “false or deceptive motivation?” An example of such motivation might be persuading parents to pay for expensive tuition when the child does not enjoy the topic and there is no realistic prospect of it producing a return (financial or otherwise) for the parents or the student. Such motivation is deceptive in that it benefits the teacher but not the people undertaking the education or paying for it. 

Education: Structure, Formats and Techniques

Teaching in age groups

In your note you mention “teaching people by school age” (or not). One formal way of describing this is teaching according to “cohort”, where people are taught according to their age range (usually grouped by “year”). This is a feature of the current education system and it is a feature which is most debatable.

The positive aspect of teaching according to cohort is that it lines up with Piaget’s theory of development. If you don’t get hung up on the details, it makes a lot of sense: babies are different to toddlers, who are different to infants, juniors, teenagers, young adults etc. These differences seem to be more obviously due to physical causes at the younger age ranges. It also seems pretty clear that there are approximate ages at which “transitions” occur, and these transitions are reflected in the breaks between the different types of school which occur in most societies (5, 6, 11, 18 etc). There are also some slightly fuzzy breaks, for example one at about 14 or 15 years old. This is actually recognised in some schools (Billy Bunter of “The Remove” (= Lower Fourth Form)) and in the Irish Education system as the so-called “Transition Year”. So, up to a point, some teaching in age groups makes sense.

Teaching in cohorts has the advantage of being efficient (even if you argue it is not effective). It can become the classic sausage machine. Someone goes in, they receive the standard processing for a fixed period, and then they come out at the end having been transformed in a specified way, or not!

That leads to the criticisms of teaching in cohorts:
·         It assumes that all students in a particular cohort are the same (or are the same within “streams” or “sets”)
·         As a result it is bad at handling the particularly able or those who have problems with a topic. In its simplest form it is especially bad at dealing with those who have inconsistent abilities.
·         Teaching in cohorts also contains an implicit assumption that certain subjects are taught almost exclusively at certain ages! Woe betide the “late developer”, adult learner, or person who didn’t have the opportunities.

In summary then, teaching in cohorts is probably justifiable as a basis for the structure of education, but there is a real risk that it limits the best and abandons the less good. Lots of people will “fall off the edge” for various reasons, and there may be no opportunity to get back on! The benefits of teaching in cohorts are strongest when people are developing physically (basically  “children”) and tail off and become negligible when dealing with adults.

Teaching Medium

One of the things you notice when you look at “Education” is how much of it is still focussed on the written word. I do it myself, both as a teacher and a learner, but it is something we should stop and think about.

On the psychology and hypnotherapy courses I took, they told us to use all the senses. They spoke about VAK: Visual, Auditory and Kinaesthetic. They pointed out that people respond differently to messages through the different senses. This is why people giving lectures will sometimes use a schematic diagram, and a list of bullet points and speak the words all to deliver the same basic message. The different channels reinforce the message (or should do, if it is done well).

Even that doesn’t do the “getting the message across” using different channels problem justice though. Still using the VAK model, you can see that further sub-categories (some of which are overlapping) are possible and useful:
·         Visual
o   The Written word
o   Pictures – as in “art”
o   Pictures – schematics and infographics
o   Pictures – Formal representations
·         Auditory
o   The spoken word
o   The auditory presentation of words – volume, rhythm, rhyme and all that
o   Music and all that involves
·         Kinaesthetic – is hardly used at all in mainstream education once you get out of infant school. Yet what else is “drill” for soldiers than training in obeying words of command and in using weapons (tools)? Why don’t we use kinaesthetic learning more than we do?
Even though I’ve given examples of how the different senses can be used in education using the VAK model, there are other senses which I haven’t touched on at all. What about taste and smell?
Let’s use a couple of examples which I think illustrate what might be possible, if we looked at what you might call “the teaching medium” differently.
One example is “the Church”, especially the more extreme forms like the Roman Catholics at one end of the scale and the more extreme Evangelicals at the other. I’m not talking about “the message” here, but how it is delivered. The Medieval cathedral: the building itself, the stained glass windows, the organ , the bells and smells (!). With the Evangelicals you get audience participation in the ritual, lots of singing and dancing and even dance!
Another example is my chemistry master. Mad as a Hatter! He was only effective as a teacher when dealing with motivated pupils, but then he was very effective. He’s the only teacher I know who (seriously) suggested tasting chemicals! Now, I wouldn’t suggest just going around tasting every white crystalline solid, but if you want to know if something is salt or sugar, what is the quickest way to find out?. If you are aware of the possibilities and that excludes the truly dangerous, then dabbing something on the tip of your tongue and then rinsing your mouth and spitting a couple of times is a very effective technique. Slaked lime tastes completely different to citric acid! Another of his innovations was a card game he called “Happy Valencies”. It worked best for ionic compounds, but the idea was to make up compounds from random elements, and or radicals. I don’t remember the rules, but I remember it was some fun. The benefit was not so much in winning the game, but in the discussions between the players about whether something was correct: do you think this is a valid formula? Can you have Vanadium Bi-carbonate?
What really surprises me is the limited range of media which are used in mainstream education. Even with the rise of the internet, we really haven’t got far beyond the printed word and the lecture. Let’s face it, among the better things you can find on the internet are the TED lectures (basic audio visual lectures, which Michael Faraday would probably recognise), and some of the tutorials on YouTube.
Given that the range is limited, the question is “why?” My answer to that would be two-fold: first, the availability of broadcast media, and second: expense.
·         The broadcasting medium of the formal education system is the spoken or written word. Lectures have been with us since at least the Greeks and Printing has been with us since Caxton. The ideas are entrenched. That’s not entirely bad. The printed word still runs most of the internet. Video and audio are coming but I don’t see much attempt to “integrate” them with classroom teaching. They are mostly used as just add-ons or substitutes.
·         Expense – It takes a lot of effort to produce even a short audio visual presentation. The cost is in two parts: the creative bit and the technical bit. The cost of the technical bit has dropped dramatically, even while I’ve been doing it, but too many people still think it is easy. It isn’t, but once done adequately, then even relatively poor material can be used again and again beneficially. It seems to me that the effort required to do the creative bit has remained the same, or possibly even increased, if people try and produce original and engaging content.

Teaching Techniques

I’m not quite sure how to separate this from the “Teaching Medium” but I think the distinction is clear from the examples.

There are different ways of teaching, and learning some are more passive and some more active (for both the teacher and the learner). They are not mutually exclusive, and an effective education scheme should probably use many of them, tailored to the needs of the students and constrained by the abilities of the teachers. Let’s look at some of them (I’m sure there are others):
·         Teach and listen – This is the traditional teaching style. The teacher gets up and tells you something and you take notes (or the teacher gives you the notes). It should be supported by exercises but too often isn’t. Many text-books in school are designed to be extensions of this approach. It’s great strength and great weakness is that the teacher does not actually have to be all that good at the topic, and can be “one chapter ahead of the students”. I have done this myself for some technical topics. Given suitable material, I would be quite happy to take a class in “bear hunting” or “how to dismantle an atomic bomb” (thankyou U2), but please don’t ask me to demonstrate either!
·         Demonstrate – The teacher shows the students how something works or how to do something. This is particularly useful for anything practical. Yes, you can learn physical skills from pictures, but it is much easier if someone shows you how. To do this the teacher has to be able to perform the demonstration. Demonstrations can be rehearsed and prepared, but anyone who has demonstrated anything will tell you that, even if you are skilful already, doing a good demonstration takes a lot of practice, and it takes nerve too. The teacher has to be prepared for something to go wrong. Even “here’s one I prepared earlier”, implies at least double the apparent effort! Doing demonstrations is inherently risky and expensive.
·         Experience – This is where the student does it for themselves. It is a very effective because they experience lots of little nuances which it is hard for even the best teacher to communicate by a lecture or demonstration. All the comments for demonstrations apply to this with knobs on! Managing students “experiencing things for themselves” requires a teacher who is knowledgeable and competent in the topic, able to teach it well, and is able to deal with the random effects of the student doing peculiar things. A devious mind which is prepared to “fix” the experience (a couple of drops of sulphuric acid in the water!) can help too.
·         Tutor – This is where the student performs exercises and the tutor gives feedback on how the exercise has been performed. The strength is that it can be tailored to the students’ needs and can be a powerful way of dealing with the more able and the less able in a particular topic. The weaknesses of the “tutor” approach are that it is expensive – it has to be “one to few”, it requires a skilful teacher, it depends on the relationship between the tutor and the student, and it can become very boring for the teacher (you see the same stupid errors again and again). For all these reasons it is probably best suited for well-motivated, mature (but not exclusively adult) learners.
·         Coach – The classic example of the coach is the sports coach, but it can be applied outside a sporting context. The distinction between the coach and the tutor is that, in the coaching situation, the student is performing the task for real some of the time. This means that the best coaches are the ones who have some experience of performing the task which is being “coached”. The coaching relationship is very dependent on the relationship between the coach and the performer. When the coaching relationship works well it is enormously beneficial to the student, but it can work badly and be damaging when the criticism is, or is perceived to be, negative and destructive.
·         Master and Apprentice – Master and Apprentice (or Apprentices) is one of the traditional ways of learning a trade. When it works properly it is extremely effective but it is open to abuse (traditionally richer parents paid for their sons to be apprenticed to a craftsman, equally traditionally apprentices were used as cheap labour, abused. Apprentices also tried to “get-off” with the Master’s daughter. (If that was carried out successfully it was a sure-fire way to a partnership. If it failed it could finish up as termination of contract with extreme prejudice!). Sticking with the “functional and effective” form of apprenticeship, the apprentice gains real practical experience direct from a master. The weakness is that it takes a long time and requires a real master of the craft who is also capable of teaching. Another weakness is that the training can be dependent on the nature of the work that the master has on hand. More recently this criticism was addressed by formal education in the form of day release schemes and the like. I rather like the idea of “apprenticeships”, providing they are done properly. 
·         Collaborators – This is an extension of the “Apprenticeship” idea which takes it a stage further, to something closer to a partnership. The relationship is still unequal, but the idea is that the participants are both bringing something to the collaboration. This kind of learning is sometimes found in academia and the arts, perhaps especially the performing arts, where youthful vigour and strength may be being traded with experience. Collaboration is a genuine learning and teaching experience, but the relationship is so personal that I don’t think it can be mandated in formal or structured situations.
Just to extend the discussion a little: think about what you remember from early life. Do you remember nursery rhymes? Of course you do! Now ask yourself whether you remember poetry or songs better than simple prose text? Most people do, yet the ideas of rhythm, rhyme and cadence are hardly used outside music classes (or, just possibly, enlightened English Literature lessons). Except for a few mnemonics and colour schemes, we just don’t do these things, yet we know they work.
Why don’t we sing or dance the Periodic Table, or differential calculus? The answer to these rhetorical (there are an awful lot of “rh” prefixes in the relevant words, which I think indicates Greek roots) questions, is that to do these things means changing the medium of teaching, requires wider and deeper skills from the teachers and challenges the hierarchical relationship between the pupil and the teacher.

Who are the “Stakeholders”?

I think “stakeholders” is an awful term, but at least it serves as a way of saying “everybody who has an interest”.
·         Learners – I wonder how much attention is given to what “the learners” get out of their education or learning experience? Probably not enough! When children are young then “education” is imposed on them with an emphasis on the “Child-minding” and “Socialisation” aspects. For adult learners, the emphasis changes to “Learning Principles”, “Learning Tasks” and “Entertainment”. The emphasis changes between people and through life. “Learning Tasks” is probably the lowest common denominator. Understanding what they get out of it, and therefore their motivation better would make the learning experience more effective and probably more fun. I think the purely social side of learning (and even “work”) is greatly undervalued. I know among the reasons I went on my Creative Writing course were, “networking” and “meeting people”.
·         Parents – Parents have several different expectations of “education”. They want children to do it because it is “good for them”, and they also want it because of the “Childminding” aspect. The phrase “in loco parentis” is telling. At least some of the time that means that they are expecting the education system to replace them! That can be a mixed thing. They are giving up control, without thinking about the control they are giving up.
·         Teachers – Obviously the objective of Teachers is to teach, to educate. In your note you mentioned them “having their rice-bowls taken away”, and I think that is a fair criticism, because teaching is also a way of earning a living, not just a vocation. Problems I perceive for the teaching profession are that expectations of the formal education system have changed and increased, without the training for teachers (or the selection of teachers for that matter) being improved. There is a feminist argument to be made here – on the one hand, “teaching” (certainly up to the beginning of Secondary School) is seen as a “feminine” and low-status occupation, and then it becomes steadily more “masculine” as you move into higher education. In defence of teachers, they are filling the roles that are created for them. They are doing what they are expected to do. Those expectations are muddled and in some cases perverse.
·         Educational Establishments If teachers can be accused of acting in their own interests, against the interests of wider society, the same charges can be laid against the Educational Establishment and educational establishments.

Taking the example of UCC (University College Cork), the original building (1849, so mid-Victorian) is deliberately modelled on an Oxford or Cambridge college. They in turn were modelled on medieval monasteries. Not only are the buildings modelled on their predecessors, but the names of the roles and the administrative structures are too.

The educational establishment (as distinct from “teachers”) is extremely resistant to change. Although that is irritating, it may actually be a good thing too, because at least it acts as a force counteracting politically motivated change.

Both education and medicine were once the province of the church. That has to be the Roman Catholic Church, because in Western Europe there was no other kind. Without being particularly anti-church it is easy to attribute at least some of the problems with education, medicine and society as a whole with the attitudes of the church in earlier times.
·         Suppliers of Educational Material - There is a whole industry concerned with the production and sale of material for education. School text-books are big business. Here’s an interesting thing, since I’ve been watching my children grow up and move through the education system, I’ve noticed that the publishers of schoolbooks are doing two, contradictory things; on the one hand they promote the use of single-use “work-books” (which can be quite a good idea), and pretty constant revisions to the curriculum when drive new editions of text-books, but on the other hand I can show you examples of where the curriculum and the exam questions are constantly being recycled. In some cases the “facts” being used are decades out of date. We’re not talking about radical scientific advances we’re talking about industrial processes. The problems I spot are the industries where I have first-hand experience – the problems are not huge, but they are significant. The nuclear reactors shown in the diagrams are designs from the 1950s, the oil distillation columns and flow-sheets are pre-war and the thermodynamics (such as it is) is obsessed with steam, and most of the kids will never see a steam engine or steam turbine. I have also noticed that the quality of the checking of material going into text-books is not really that good. Misleading typographical errors do get in.
The problem with this is that in most cases, “the teachers” do not recognise these problems, because they are not in a position to. They teach to the curriculum (which in some cases is churning, but not necessarily moving forward) because that is what they are paid to do (and they are criticised if they don’t), and use the text-books which they are told to use (because there isn’t much else and you need to have a common text).

Why does this happen? The publishers are now in it for profit, rather than interest in communicating the topics. Churning the curriculum and the content of the text-books is good for profits, because it is relatively low cost and it means that old editions cannot be used, therefore creating new sales. On the other hand, creating really new content is hard and expensive. Even deciding what to include and what to leave out is hard. It is hard and expensive, so it doesn’t get done. The results are bad for the teachers, because they (especially the ones who are “teaching from the curriculum and the text-book” rather than from deeper knowledge) find themselves running to stand still, and bad any consumers, because the real content is ossified. Of course, all the change creates the illusion of change and the impression that “something is being done”! That means the politicians like it, or don’t notice it.
·         The Qualification and Certification Industry – Have you noticed how keen people are on “Qualifications”? It’s like the Scarecrow being given a diploma by the wizard in “Wizard of Oz”.

There is a whole industry (somewhat independent of the “Education”) devoted to issuing and validating certificates and other credentials. Issuing credentials is not that hard: you test someone in some way, you give them a “certificate” to say that they have met the requirements, and you keep a record that you have issued the certificate. If you out-source the actual testing, then there is nothing else to do! The only thing you really need is a reputation (and perhaps a small computer for the records). The certification industry, loves “re-validation” and “continuous professional development” schemes because they create work for it, regular, predictable work they can charge fees for.

I’m not against “qualifications” as such. I have plenty of them! And I worked hard for some of them too (I didn’t work hard for my “Ordination” or “Doctor of Divinity” (yes, you may address me “Reverend Doctor”. I stopped short of Archbishop, because one must have some ambitions!), but I have the certificates and I never use them!). We have to recognise “certificates” for what they are: a short-hand way of saying that someone is qualified to do something for people who do not have the time, inclination or skill to prove it for themselves. If you want a welder for a pressure vessel, you look at his Lloyds Certificates and then you set him a trade-test and say “weld that”, and then you x-ray and ultrasound the results (if you care).

Like I say, I’m not actually against certificates, but they are very popular with frauds, HR departments and with recruiting agents (who couldn’t tell if someone who someone could do “x” if it got up and bit them!). I have seen a lot of people (and I know you have too) who seem to be highly qualified, and who can’t do the job. I have also seen a lot of people who are interested in learning to pass the exam rather than be any good at the job.
·         The Powerful – As I have been writing this I have come to a rather cynical (surprise, surprise) conclusion about education. That conclusion starts off with my “Socialisation” category in the “Purpose” section. Socialisation is a genuine and essential objective. However, socialisation can also be intended to provide “control”. Look on it as a “feed-forward” (not “feed-back” control system). The thing about “feed-forward” systems is that they set everything up to make life easier for the feed-back systems to keep everything on track. They produce stability, but they mean it is very hard to change. They presuppose what the result should be and do not take account of feedback from the environment and real results.

The thing that makes me suspicious about the current education system is the way it is partitioned vertically. I’m not just talking about the socialist ideal of “Comprehensive education”. That is probably not a good objective anyway. I am talking about the way the education system is in silos, which assume that someone will go into one stream at the start and then proceed to the end when they “pop-out”. In Britain they seem to be going back to the idea of Grammar Schools – but that implied a “pass-fail” test at 11-plus. The post war education theorists didn’t intend that in the first place. They intended a bit of that, yes, but they really intended testing on “aptitude” with there being three tracks: Grammar, Secondary Modern, and a Technical School. The “Technical Schools” were hardly ever implemented.

My point is that at several levels, the education system seems designed to promote “Us and them” thinking, with one group being in charge and the other taking orders. There is precious little encouragement to “crossover” at any point. (And of course, those in power would not wish to!)
·         Consumers of the product You will hear a lot of complaints from “industry” that “education” is not providing what they need. This is especially true with regard to the STEM (Science, Technology, Engineering. Mathematics) subjects. You can add “Computer Programming” to that as well. I am coming round to the conclusion that this is actually a delusion. What they are really asking for is more people with the “Task Oriented Skills” they need. They want the education system to do their “Training” for them. They want to be supplied with “fodder” and then when they don’t up-skill their workers, they want to be supplied with new “fodder” which meets their requirements (which they didn’t state in the first place). And they don’t want to pay the taxes which would support the provision of such people.

How do you measure success?

One of the issues with the Education system is the question of “how do you measure success?” The problem is that what you choose to measure and how you measure it has started to influence what is being taught! I think I see an increasing preference towards short answers, yes/no and multiple choice. Such approaches have a place, but not everything can be reduced to simple questions. I’m not arguing that all examinations should be “wordy essays” either. They have a place too but they shouldn’t be everything.

My real point is that we may decide that something is worth doing, but is “worth doing badly”. Some art (as in decoration) is like this. Art used as therapy is like this – we don’t care what it looks like but perhaps the act of producing it is beneficial to the student/patient so we show them how to do it. First Aid can be a bit like this. Yes I want people trained not to do dangerous things, but most of all I want them to be prepared (Scouts’ motto “Be Prepared”), not panic and to be able to do something, almost anything. I don’t care if they have got a Red Cross Certificate, and I certainly don’t care if they have a Red Cross Certificate which is out of date!

Mainstream education is beginning to ignore some of this and take the view that if it can’t be measured (worse, if it can’t be measured easily), then it isn’t worth teaching. I have a bee in my bonnet about the decline in the amount of practical work done in Chemistry (mostly because it is perceived as “dangerous”, but also because the teachers are uncomfortable with practical experiments. Using videos (which have a place as well) is becoming commonplace. As I have said to **** “do you want to send them to University without having done practical experiments? They have really dangerous things in university labs!”

Education in Ireland

I’ll start by saying that education in Ireland is not that different to education in the UK. That is not surprising, the linked history and shared culture mean that a lot of institutions in Ireland are either derived from the UK version (eg the law, education and medicine) or are a reaction against the situation in the UK (the status and role of the Catholic Church).

Something that you have to bear in mind is the moment when Ireland “forked” (to use the code-version analogy) from the UK. This is something that happened between 1916 (the Easter Rising) and 1922 (when the Ireland became an independent country). The significance of this is that the UK situation that Eire is derived from or reacting against is often as it was towards the end of the First World War! We have all moved on a bit since then.

The majority of Irish primary and secondary Education is effectively run in the name of the Catholic Church on behalf of the state. The amount of influence the Church actually has varies, and has diminished considerably since the foundation of the state. That diminution has accelerated in recent years, as a result of changes in the political situation and scandals involving the Church.

Historically, Ireland has a tradition of higher education (“land of saints and scholars” and all that), but the layering of a dominant Anglo-Irish aristocracy over an “Irish” peasantry means that there was less of a demand/need for a domestic higher education system (some contentious theorising there). Higher education was concentrated in Dublin (“within the pale”). The institution which has become UCC (University College Cork) was founded in 1845 along with another 2 colleges. One of its original purposes was to provide doctors for the armed forces of the British Empire. More recently there have been other Universities and Colleges formed, and there are smaller colleges of further education.
Just as in the UK, the whole education system (certainly up to Secondary level) has a Public and Private sector. This is also mixed with a religious ethos. Many of the prestigious private schools are run by, or on behalf of, Catholic Religious Orders. There are Protestant (Church of Ireland) private schools, but very few. Just as in the UK it is possible to buy an education that will get you into a prestigious college.

I would describe a lot of the Irish Education system as a little old-fashioned, and maybe none-the-worse for that. We have done alright out of the Irish system. Remember, a good system can produce bad results and a bad system can produce good results. I think that attending relatively small schools with stable teaching staff in a community which has a strong identity has had more positive effect than anything to do with any particular “system”.
The one major (and it is pretty major) criticism I have of the Irish system is their obsession with the “Leaving Cert”. In my opinion this distorts the whole of the secondary education to a serious and damaging extent!

The Leaving Certificate works in a similar way to the English and Welsh ”A Levels”. The function is the same: to provide an exam to demonstrate achievement at the end of Secondary Education and to provide a “points” mechanism used to control access to Higher Education. The problem with the Irish Leaving Cert is that it is “all or nothing”. You cannot top it up with additional subjects later. If you have one bad result, then you resit the whole set of exams the following year. You can use either result, but you can’t mix them. The result is that there is an obsession with the Leaving Cert results. There is a whole sub-culture of extra tuition (“grinds”) and there are no “A Level” courses for individual subjects at evening classes (because there is no point). What there are, is specialist schools (paid for) who specialise in getting people to pass exams. And (here’s a good one), weaker students take extra subjects, because by doing so they can boost their points score. The whole system promotes “rote” learning, discards people with unusual skill profiles and generally increases stress. The Leaving Cert takes “teaching by cohort” to the extreme. It is not a good system, and it is a system which is almost guaranteed to produce “undesired consequences”.

Discussion

Without really meaning to, I’ve scattered “discussion” through this essay, but I would like to bring together some of the themes I’ve identified as I’ve been writing.
·         There is widespread agreement that there are problems with the education system in the UK and Ireland.
·         Although people might not identify the expectations I have described, they would probably recognise them when they are pointed out.
·         The problem is not so much the objectives as the relative priority given to those objectives by different “stakeholders”.
·         One of the issues is that the different stakeholders are all pursuing their own agendas. There is nothing wrong with that, but some of the stakeholders are pursuing their own agenda without any consideration of the others or regard to “Society as a whole” (whatever that is).
·         I think an extreme case of this is the way “those in power” (right and left wing) use a divided education system (private for the privileged and public for the rest), and continue use the education system to promote “socialisation” (or conditioning or indoctrination) into particular roles.
·         The education system is being used partly as an instrument of control. It is being used to control the “socialisation” aspect, but also the teaching of “task” and “principles” to say nothing of being used to manipulate unemployment figures (“child-minding”).
·         Such control is a legitimate concern of the state and the powerful (whether we like it or not), but with the conflicting input from the various stakeholders, the result is confusion.
·         Another factor is that the state or official system is being asked to do too much. There are too many conflicting requirements. The result is not a workable compromise but instead a rather wasteful muddle.
·         In many cases there are attempts to apply too much control, especially the formal, bureaucratic form of control. It’s classic micro-management.
·         Education is not something which is easy to control. Even if we restrict ourselves to “formal education”, that takes from age 5-16, that’s 11 years, rising to 16 or so years if you include higher education. If the decision making is centralised with all policy being made by central government, then that’s all wrong. Changes may be made at 2 to 3 times the rate at which one can monitor the actual effect of those changes! It is not a design for a controllable system. At the same time, most people would argue that education needs to be more responsive. That suggests more change, more frequently. The only way to achieve that is with some level of de-centralisation with delegation and central coordination (maybe a small, core national curriculum).

What would I do differently?

·         The first thing I wouldn’t do, is try to change everything. There has been too much of that.
·         If I were to change one thing in Ireland, it would be to remove the “Leaving Cert” and replace it with exactly the same exams, but allow students to take individual components separately.
·         I would aim to start removing rigid age bands. Some banding is convenient, but the rigidity is a problem.
·         I would promote “life-long learning”. Part of that would be to pare back the compulsory and rigid bits of the formal state system while promoting add-ons running along-side and in addition to the state, formal system.
·         One benefit of having “extra bits” is it would create opportunities to experiment with alternative teaching methods. Things that seemed to work could be disseminated. Things that didn’t work would probably die out without much action being necessary.

Conclusion

At almost every level “education” seems to be filled with contradictions. In some cases these give rise to what seem to be paradoxes.

Part of the problem seems to be that formal education is asked to do too much. The competing requirements, especially the use of education for “control” by conflicting groups mean that it cannot achieve any objective effectively.

Answer: Do less and do more. Have a less rigid formal structure, with a firm (but not rigid) central curriculum and timetable and then promote additional and life-long learning as add-ons.



Things worth watching

These are not “references” in the conventional sense, but they are worth watching. They are only 15 mins each. They are all by Ken Robinson. The first one is best.

At his best Ken Robinson is an engaging and thought-provoking speaker, but at his worst you could criticise him for diagnosing a problem without really offering a solution and for saying “I wouldn’t start from here if I were you”!

Here is a presentation by Dennis Yang,the CEO of Udemy. This is a sales pitch. I’m not pushing anything, but it is interesting to hear the sales pitch from the service provider’s point of view:
Piaget’s theory of development:
Mark Timberlake (I know you haven’t heard of him) on “Avoiding Get Rich Quick schemes”:
The metaphor used is interesting.  I like Mark, and he is one of the people I “follow” on the internet.  I don’t agree with him about everything, but he is more successful (using various measures) than I am, so he is worth copying. Example of “informal education”. Things I like are:
  • ·         Good High “production values”
  • ·         Experimentation with different techniques
  • ·         Aiming to run as a low investment “craft” business
