On using a title

Years ago, I was asked for my name for some National Health Service form, by a receptionist whose first language was not English. After she struggled with the spelling of my surname, I just passed over a credit card so she could copy it. It showed my title as "Dr", and I lost my mini-campaign to be treated as normal by the NHS. Not that I am discriminated against in my thankfully so far limited contact with them, it is just that using my academic title confuses the system, wastes time as I have to explain I'm not a medic., and has medical staff "explaining" things to me in technical language which means nothing... All--admittedly rather desultory--efforts to get it changed have so far had no effect, despite assurances.

But I do remember one wise doctor on a course who greeted me with, "Are you one of us, or a proper one?" In the UK, strangely enough, the medical "Dr" is a courtesy title, because the MD is rare; most medics are "MB, BS" (or "MB, ChB"--two unclassified bachelor's degrees, in any case) and of course to the disconcertion of foreigners taken ill in the UK, surgeons are "Mr" or "Miss"*. By "proper one" he meant an academic doctorate, although of course there was no telling what its private connotations were ...

It came up again last week, in an out-patients' waiting room--and everyone looked up as I responded to the call for "Dr Atherton". I'm probably being hyper-sensitive and it's all trivial but I mention it because...

I've just been watching a Newsnight piece on the postponement of the badger cull. The two interviewees were a representative of the National Farmers' Union, and Dr Brian May speaking for "Team Badger". The title appeared in his on-screen label, as well as in Paxman's introduction. There is no doubt as to his entitlement to the title: PhD, Imperial College London, 2007**. In astrophysics. How does that--or indeed the reason which probably actually got him onto the programme--his previous association with some popular musical group called "Queen"--relate to his credibility as a badger advocate? (I'm with him on the badgers, as a cause, so I feel let down by his apparent need to appeal to false -OK, irrelevant--credentials.)


*  this is entirely a matter of convention, and as far as I know, the standard and equivalence of UK medical qualifications is globally acknowledged.

**  and all credit to him for completing it thirty years after starting it--lucky he did not fall foul of the pernicious "Levinsky rules".

On Savile and his heritage

I don't much want to comment on the sordid case of Jimmy Savile, although I too had heard the rumours, years ago. But I have commented on similar issues here and here and elsewhere, trying to understand some of the issues which the promised inquiries will pursue.

Nige of Nigeness has an excellent (if arguable) piece about the basic problem of recognising a "wrong 'un".

I'm more concerned at the moment about the potential consequences. The Soham murders, for example, triggered a disproportionate "safeguarding" apparatus which probably had no positive but many negative consequences (Ian Huntley could apparently have been stopped by the diligent application of measures already in place) while the impact of new regulations may well have discouraged many potential volunteers from getting involved in youth groups, uniformed organisations, and even helping out neighbours...

Whitaker and Lieberman (1964) discuss how, confronted with a "focal conflict" of deep concern to a group, the group can all too readily come to a "knee-jerk" response, which they call a restrictive solution. That effectively puts a plaster on the problem, but at later great cost to the group. In their context (which was psychotherapy) they argue that the critical task is to get beyond such a response to a facilitating solution. The same process seems to occur in the political world, too, particularly when the cry to "do something" is amplified by the tabloid press. It takes great presence of mind to maintain a sort of "negative capability" and not to act. That may be one reason why the immediate reaction of politicians nowadays seems to be to call for an inquiry. It takes time, allows some passions to cool, and distances the events--and it's certainly better than the usual restrictive solutions such as scape-goating or ill-considered legislation (Dangerous Dogs Act, anyone?)

There are some interesting pieces cropping up in today's papers, exploring the argument about whether there was really a "different culture" back in the '70s and '80s; about the assumption of untrustworthiness which pervades the perception of adults; and Minette Marin in the Sunday Times (unfortunately behind a paywall) saying the unsayable, that women and girls should toughen up and not make such a big deal out of the "casual sexism" end of the spectrum.

It's a sad coincidence that yesterday Stuart Bell MP died: he resigned from the opposition front bench in 1987 so as to be free to fight the case of the families caught up in the Cleveland child abuse saga, when 121 children were removed from their parents amid allegations of organised sexual abuse, stemming from the reports of two paediatric consultants, and based on fallacious interpretations of one test. And then there was the Orkney "satanic abuse" case of 1991...

Whatever the casual sexual harassment which pervaded the BBC and other work-places, the evidence of such panic reactions by the authorities testifies to sensitivity to allegations more than twenty years ago. Just not to allegations made directly by victims, against powerful people.

On learning and Bayesian statistics

I have--rather to my surprise--just finished reading Sharon Bertsch McGrayne's The theory that would not die (London; Yale U P, 2011). I only picked it up because there was a 3 for 2 offer in the bookshop and I needed a third book in order not to miss out. The sub-title says it all: "How Bayes' rule cracked the Enigma code, hunted down Russian submarines, and emerged triumphant from two centuries of controversy." I first came across Bayes' theorem through an Open University course on Professional Judgment* in the later '80s, in the days when their courses were supported by late-night programmes on TV. As usual with those programmes, particularly in maths, I thought I understood them perfectly at the time but the understanding just evaporated within hours... Even so, the basic idea has stuck with me for twenty-odd years, which is more than I can say for the MOOC...

So what is Bayes/Laplace's theorem/rule? My understanding is limited, but it is fundamentally a statistical approach to informing decision-making under conditions of uncertainty and incomplete information, by refining probabilities based on information about prior conditions as well as current measurements/ assessments. To me, the overall process seems very like the way in which betting odds are arrived at (where the money bet is a proxy for positive or negative information about the object of the wager); or as Keynes put it, "When the facts change, I change my opinion. What do you do, sir?" (epigraph to McGrayne).

Here is a more respectable, and of course more detailed, account.

I was already aware of some of the basic principles as applied to assessment (here)...But here is why I am mentioning it now--it came up as a current story. 

McGrayne doesn't make the links to learning very much (just on p.158 and pp.247/8.) But it's not a giant leap of insight to make the connection between learning through successively better approximations and Bayesian principles:
  • Piagetian principles of adaptation-- assimilation and accommodation--are consistent with a Bayesian framework.The progress of a Bayesian calculation--up-dating predictions or odds on the basis of greater knowledge, is basically similar to Piaget's view of children's learning through assimilation, where each new instance of a concept informs and adds to existing understanding (as discussed in the bold linked article above).
  • And Hattie's meta-analytic findings on the importance of feedback  also fit, particularly the passage I quote on feedback from learner to teacher. The teacher is continually making adjustments to her strategy based on refinement of her uncertain and imperfect knowledge--some Bayesian understanding of the process may well help with the formulation of her strategy, and although this may be difficult to achieve in real time in the classroom, one can see how it could possibly be incorporated into an assessment strategy, or indeed an online course.
Or is the characteristic sound of a Sunday morning the sound of me barking up the wrong tree? (As Penelope Gilliat said of Harold Hobson.) The probability of that could also be computed using Bayes'. Probably.


*  See the reader for the course: Dowie J and Elstein A (eds.) (1988) Professional Judgment; a reader in clinical decision making Cambridge; Cambridge U P. Incidentally I also wrote about it here. What I realise only now--since reading McGrayne-- is that the dissenting voice granted a couple of minutes at the end of each programme represented an almighty row which was going on in the world of statistics; the main programme was unashamedly Bayesian, while the comment presumably represented the mainstream view, which McGrayne typifies as "frequentist".

On the MOOC -- 4: Forums and Assignments

This is the last in a series of posts about participation in the free Massive Online Open Course [MOOC] on the History of the World since 1300 CE, from Princeton U via Coursera. Jonathan Rees, at More or Less Bunk, is also blogging his take on it. I'm sure he has more readers than me, so if you feel like commenting, please do there first--no objection of course to getting his leftovers!

I promised I'd look at the forums on the MOOC. It's when you do this that you realise just what "Massive" means. I gather that about 70,000 people are signed up, all over the world. (Here's a map of the distribution, as entered by participants.) Not everyone is posting, of course, but the simple truth must be that the "community" is unmanageable--and was always going to be. As Adelman has noted:
"The Forums have become an active site for the exchange of ideas, information, and solutions to technical problems. They are now overwhelmed. This "common good" that we have created is getting crowded out and I fear many of you will stop turning to it as a resource. I am no longer able to keep up with your conversations and as a result you are loosing (sic.) my engagement in the course." (Adelman, Thu 20 Sep 2012 1:14:00 PM BST)  
Coursera has been working on the threading and the facilities in the forums, but a casual review shows that despite entreaties from the moderating Teaching Assistants and Adelman himself, there are many repeated questions sometimes coming up on inappropriate forums. I'm sure that this is not because people can't be bothered to post appropriately, but that they don't know how to find the topic they are interested in.

But dig into the more specific and targeted sub-forums, and the impression which emerges is of a very thoughtful and well-informed conversation (with of course the occasional troll). And I can't fail to be impressed by the commitment of Adelman and his T.A.s to respond to the conversation; having run on-line courses myself, with much smaller groups, I'm well aware of how time-consuming it is. Despite his fears in the quotation above, he seems far from disengaged.

One feature of the lecture discussions which I suspect is unusual, however, is the number of posts correcting the lecturer (and even the textbook), which point to the atypicality of the constituency!

Just impressionistically, I've been trying to detect other more general patterns. Clearly some of the exchanges  take the format of hub and spoke, particularly when Adelman is involved, and that is as one would expect with the instructor responding to comments and questions. Others are more like nets, typically with just a few participants. I haven't come across any very long "rallies", as it were. But the regrettably typical viciousness which seems to characterise on-line arguments is sometimes here, too... It is very difficult to generalise--the course is so big that anything might appear.

Does it matter? Probably not. By which I mean that the forums are probably essential, regardless of what proportion of participants use them. In a MOOC, you're never likely to have them embarrassingly empty, which can all too easily happen in an ordinary on-line course, and leads to the use of assessment credits for level of participation almost regardless of a quality of content, which is a tactic fraught with unintended consequences. It may well be what they stand for which matters, rather than what they are supposed to achieve. They represent an essential channel back to the course organisers and teachers. They acknowledge, however crudely, many participants' desire to be part of a community which can share experiences and queries. They can model effective participation and the level of background knowledge expected of participants (dauntingly high on the evidence of what I've read so far, but then I'm not an historian). And I speak from experience when I say that the obligation to engage in forums as a tutor is a brilliant way to get a feel for your student group. "A" feel, of course. Not necessarily the best or most representative one, though.

Assignments

The first assignment was due yesterday. There was a choice from three titles, one of which was:
Option A - What changed, and what survived, as a result of the plagues and disasters of the fourteenth-century in Afro-Eurasia?
Faced with such a title, I realised I hadn't a clue what to do with it. Partly that was because I recognised that I don't actually know very much about what happened--and that may well be because I have concentrated far too much on the online pedagogy of the course rather than its content. And partly it is because it is over thirty years since I have had to write like that at someone else's behest; I no longer know how to do it, other than that I would start by deconstructing the title... (And I gave up setting assignments of that kind in my own teaching about sixteen years ago.)

I also don't know at what level the assignment is set. Looking at the provided guidance on writing, I am struck by its emphasis on clear expression of an answer.
Don’t present a reader with competing arguments and hope they can make up their mind.  [...] The reader wants to know what you think.
and, in the assessment criteria:
3 points - A clear response to the question in the terms posed in the assignment. 
(My emphasis) Oh well, bang goes the idea of deconstructing the title!

I'm probably making this more complicated than it really is, but the title could be calling for a basically narrative and factual account of changes and continuities on the lower levels of Bloom's taxonomy in the cognitive domain, or it could be demanding synthesis and evaluation, although that is something of a tall order with a 750-word limit. Actually, I think the titles are well chosen, and, like the multiple choice quizzes at the end of the lecture segments, they do force one to think about the processes of change, which is a main theme of the course. My difficulty is with the effectiveness of this kind of exercise as a teaching device; the constraints of the online format are both limiting and shaping content and process of the course.

This becomes even clearer in the guidance on how to write the essay:
"Material for these essays should be only drawn from lectures, recommended readings from Worlds Together, Worlds Apart and comments from the Forums from this course [...] This is important because peers will assess each other based on the knowledge they share from this course."
I've never been keen on sticking to set reading, at the best of times. But the reason for requiring it here, to facilitate the peer assessment (good idea in itself, but...) really shows that the constraints of the medium have won, well thought through though the actual peer assessment seems to be.

Of course, this may well suggest that there are epistemological considerations in what content is suited to being taught online. History is, like other humanities subjects, contestable. It is studied not only for its own sake, but also in order to develop skills of critical thinking and argument--and so its teaching media need to support that process. In STEM subjects, on the other hand, the balance is much further in favour of sheer content--at least, Laurillard argues, until the final undergraduate year. The distinction is allied to that between divergent and convergent thinking (Hudson, 1967).

However, I have now fallen so far behind, and missed the deadline for the first essay, that I and the MOOC are parting company (the attrition rate is enormous, supposedly 80-90%). It's partly because the announced time-commitment (up to seven hours a week) is more than I can manage at the moment, but it is also because the experience has been distinctly unrewarding. After less than three weeks, it has become a chore; but that may well say more about me than about the MOOC itself.

Here are some recent related pieces from other people:

On informal learning and being nerdy

I've just been watching Evan Davis' Built in Britain on BBC2, and getting increasingly irritated about things probably no-one else has noticed. But I've just realised that I've acquired my sensitivity to them without ever having been taught them--purely from problem-solving experience.

Sync.I linked to the actual programme on iPlayer, because you need to see some of the speech-to-camera shots to get this. The sound/vision synchronisation is out, probably by only one frame (in old money), and in real-time I can't tell in which direction--but it bugs me!

My first efforts at movie-making were around 1960, and for amateurs the addition of sound (even as a mood musical accompaniment) was a considerable technical challenge, involving ingenious devices such as the Synchrodek.) I had --indeed still have--a Eumig P8 phonomatic projector which used a rheostat system to allow a reel-to-reel tape recorder to control the projection speed and achieve (after a fiddly cueing set-up) synchronisation to within half a second over a 200ft. reel  (about 15 minutes). "Lip-sync"--matching speech-sound to lip movement (effectively better than 0.06s)--was merely an aspiration...

I became hyper-sensitive to sync. Nowadays it should not be an issue. Video records video and sound together, and editing packages treat them as locked together by default. I can synchronise and mix a multi-camera setup using domestic/recreational standard kit on the basis of a simple loud clap, or a flash. (OK, there are more complicated scenarios, I admit.)

But it really gets my goat when I watch a TV documentary (such as an expose of funeral directors which I also watched in the past couple of weeks) where there are simple, straightforward interviews, and somehow they have managed to get the sync. a frame or two out. A few years ago, there was an ad campaign for a men's hair dye called "Grecian 2000" which was probably dubbed, but I felt the lack of attention to synchronisation said something about the advertiser's lack of respect for its audience. (Good grief--it's still being sold--Google turned up 1,830,000 hits for it.)

I sometimes think I am the only person who notices. I put that down to my heightened sensitivity from dealing with the challenge for 45 years (off and on)--but apart from occasional conversations at Altrincham Cine Club  (now apparently Altrincham Video Society) in the early '70s, I've never been "taught" that perspective.

I've gone on longer than I planned. But---the programme this evening also suffered from a problem (to my ears) with sound perspective. The interviews and the to-camera pieces were, to my ears, too uniformly "dead". Beautifully clear--but no ambience. And don't get me started on aspect ratios (particularly with still inserts--there were no problems before Ken Morse retired)...

OK--rant over! It's not the content which matters, so much as the way I (and I am in no way special) learned it. Alan Tough's thinking about adults' learning projects (1971) is rarely referred to nowadays, but fits exactly my acquisition of my (admittedly half-baked) knowledge and skills about movie- and video-making. And although I had previously thought of this as a matter of hints and tips, and the product of practice--important though that is--I'm coming to realise that without ever setting out to do so, that learning has changed my perception and what I pay attention to. It is not a matter of choice--I am unable to ignore these trivial but--to me--profoundly irritating faults. And of course it is a distraction from the content.

But--would I rather be able to ignore this stuff? Hmmm...

On fifty years on

I just realised that later this month it will be half a century since the Cuban missile crisis.

I was in my final year at school. I was preparing for scholarship examinations for Oxbridge (I didn't succeed). I remember very clearly sitting on the steps of the podium in the school assembly hall, talking to a couple of friends. One of them asked, "How long do you think we've got?" I replied, on the basis of no real knowledge, of course, but aspiring to be a 17-year-old sage,"About three weeks". I believed it, and I was far from alone.

The Cold War was real and in those three weeks it was on a nuclear hair trigger. The prospect was of being blown off the face of the earth, with just four minutes' warning. The apocalypse really was on the horizon.

I also remember watching the news coverage of the denouement, and apparently being alone in thinking that Khruschev had "won".

And I failed to rise to the occasion (in several senses)---my adolescent existentialism withered when confronted by my equally adolescent evangelicalism (of course my then girl-friend's catholicism didn't help...)

The apocalypse didn't happen, and my wife is now on holiday in Cuba.

So it goes.

On a busman's holiday

I have delayed posting this for some time, because I don't want to point the finger at anyone, publicly. I debated whether or not to post it at all. As it stands it is merely opinionated commentary--a legitimate form of expression, but not one which can claim the interest of a reader. I am actually posting it to supplement my posting on a MOOC--where I have paraphrased and condensed some points, including events which happened after I wrote this version. Sorry--you didn't need to know that, did you?


I am on holiday; for once on a tour organised around a topic--the history of classical Greece. I won't go into more specifics for reasons which will become apparent.

On the whole it has been excellent. The site visits have been informative, and there is no substitute for going to the real locations. The organisation and the food have been almost exemplary. And the company of the other members of the party has been excellent.

Unfortunately the same cannot be said for the lecturer.

As I sat in the first lecture on the first morning, I berated myself for not having brought my trusty observation sheets with me. Had he been a student, I should not have been able to sign off on any item on my list. That is not in itself a problem (see here, for example), and indeed some of the things we are obliged to check would have been clearly inappropriate, such as "embedding functional skills". (It doesn't matter what that means.)

I note, re-reading the earlier post, that I commented then:
It was not about the tutor's technique... It was about "strategy", or really values.
And therein lies the difference. The lecturer started the session with the air of the whole thing being slightly beneath him--to think that it has come to this, to be hired by a package-tour company to lecture to a group of elderly people... There was evidence to support this, because he had clearly done very little preparation, despite--or perhaps because of--his apparent familiarity with the material. I say "apparent" because other members of the group who are more familiar with it than me have been more disparaging about his scholarship.

He did ask us who was in Greece for the first time. Otherwise he asked us no more questions. He said nothing about himself and his background, other than that this was the sixth time he had done this particular tour, and let slip references later to up to fifty years of visiting the eastern Mediterranean. He did decide not to undertake introductions, which was a fair call, probably; he obviously defined his role as an "expert" rather than a full-scale teacher. But it would have been interesting if he had shown just a small proportion of the interest in us which he clearly expected we would have in him. A show of hands on who were the old hands? On who spoke or read Greek? Considered themselves well-informed about the architecture, the history, the culture...? Five minutes would have sufficed.

He said he would get to know our names as time went on, and he did do that. (I could have said that he achieved this principally by counting us onto the bus, but that would be even snarkier than this account is already. Credit where credit is due!) But he missed out on so much information which could have been useful to a more confident and less arrogant person; there were people in the group with expertise from their professional backgrounds and travels who could have contributed fascinating material, which in practice was only shared with two or three others chatting over dinner.

Although I was not expecting and would not have wanted reams of paperwork, it would have been useful to have a list of titles of the lectures. However, it became apparent that in his view this was one long lecture which he would deliver in a series of chunks. Throughout the rest of the week, there was only the most token obeisance in the direction of a clear start and finish (except a sort of peroration in one talk given on the coach, but that was more about drama than structure).

He did supply a reading list; it was badly formatted and the bibliographical format was not standard. Who cares? Well, publishers and dates are quite useful. Perhaps more important, it had been corrected in long-hand and then copied without being re-typed. This clearly sends a message to the "class" that they are not worth serving properly; it amounts to an expression of contempt.

No visual aids. Well, he did have a carrier bag with some copies of picures from books, laminated, so he could hand them round. Given that all but the first of the talks were given on the coach, there might be something to be said for that, but the logistics of distribution and the number of copies, and their labelling, needs some thought. There was a single copy of each page to be shared sequentially among two dozen people, even if most of them were couples and would look at the page together.

He had prepared two pages on a flip-chart, though, showing a time-line. They were sloppily printed in marker pen, but they were big enough to read and he had covered them up with a blank sheet so they were not distracting until deliberately revealed.

So no presentation package, probably because of the setting of the talks, but also because I don't think he has the necessary skills to develop a slide-show. That might also account for the hand-written corrections on the book-list. Even so, the most important thing he could have achieved through a presentation, he could also have achieved for himself with a handful of 6x4 cards--a structure. But the consequence was that, together with a voice which sometimes descends into a mumble, and some irritating mannerisms, it was almost impossible to follow what he was talking about.

It is an egregious delusion that just because you know (or think you know) a lot about something, you can lecture about it. Even in an open-ended situation where the intention is to inform and perhaps entertain, where the group will not be assessed and they are free to take it or leave it at their discretion, where the language of "objectives" and "outcomes" is inappropriate--even then you need a structure. And when you are inclined to ramble on in a kind of drunkard's walk from one topic to another with little evidence of a theme, you definitely need a structure. I know because that is what I do, left to my own devices.

The simplest device of notes or a set of cards, each with only a key word or phrase on them demands some degree of planning. Cards are of course more flexible because you can re-order them, or take one out when you have answered a point in response to a question, earlier than planned...

So all this is very very basic. For most of the week I have been juggling hypotheses about what is going on. Is he merely incompetent? He is incompetent, but not merely so. His failings can be superficially rectified with advice, should he be inclined to accept it. But there is I think more to it than that; there's a fundamental self-absorption which suggests he hasn't got a clue about how other people respond to him and his work, and he doesn't care. (Apparently, nor does the company--I am led to believe that there has been critical feedback about him for years, but he is still employed.)

Beginning teachers are often very concerned about their own "performance" to the extent of not being able to pay attention to the students' performance; that's a natural stage which is soon overcome in most cases, and in any case their self-consciousness often makes them eager to seek and respond to feedback. For whatever reason, this guy is stuck...

But... all this does not extend to other aspects of his public role. Mingling with guests at social functions he is a little stiff and has to try hard to be charming. I empathise. I'm pretty inept at that, too: but then I don't set myself up to do a job which requires such skills. Tonight was a supposedly special dinner--characterised only by having to sit at long tables rather than self-selected small ones, and he was in "host" role. He was clearly not comfortable but he pulled it off quite well--better than I could have done, certainly. But his performance in making a simple vote of thanks for the organiser was largely about him and his next destination.

Something happens to this guy when he assumes the mantle of teacher or authority figure. What, why, how?

Thank goodness for local guides!

[There's no definitive answer, of course. But if you are tackling "the role of the teacher" on a post-school and adult education teacher training course, I think you might find this case-study stimulating.]

On the MOOC -- 3

This is one of a series of posts about participation in the free Massive Online Open Course [MOOC] on the History of the World since 1300 CE, from Princeton U via Coursera. Jonathan Rees, at More or Less Bunk, is also blogging his take on it. I'm sure he has more readers than me, so if you feel like commenting, please do there first--no objection of course to getting his leftovers!

I was going to talk about the forums this time, but an announcement tells us that they are still working on the "Global Dialogue", so I'll hold off that for a while.

This is getting harder work (and it is still only week 2). I started the first lecture of the week on Monday. I haven't been unusually busy this week but I didn't get to its third segment until Friday afternoon and its fourth on Saturday. It's not that the content is getting any more difficult, by any means. It's just that the prospect of another quarter-hour or so of Adelman's halting nasal sing-song drone is not exactly inviting. Nothing personal and not his fault, but putting him up as the presenter says interesting things about the course design.

We know that video lectures can be compelling stuff. TED talks are hugely popular, and perhaps the producers of this course have learned something from them in breaking the lectures up into chunks of under twenty minutes. But TED talks are rigorously rehearsed, with a professional director advising on expression, and pace, and visual aids... (Not to mention that presenters are presumably selected in part on the basis of their screen presence and articulacy, in the first place.)

Adelman has, in a sense, "rehearsed", in that he has delivered these lectures live, before. And to his credit he is not reading them from an autocue. But it doesn't appear that he has rehearsed specifically for this recording. And he is not in a lecture theatre with real live students around, just in a studio with his two assistants and a few technicians--and if he is in a studio, why is the assistants' sound hook-up so bad?  He may not realise it, but he is missing a whole world of feedback from his non-existent audience. Their posture, their expressions, their dozing disengagement, occasional blankness as they miss a point; the opportunity to focus on a particular student or two as barometers of engagement and interest--all that is missing, and a half-decent lecturer makes more use of that than she recognises. It is as if he were singing in an acoustically dead room, rather than in the shower... (I am giving him the benefit of the doubt here--his singing in the shower may well be as irredeemably dire as mine!)

There are two ways of re-couping that situation. Rehearsal and re-takes. They are basically the same thing--repeat performances until you get it right, either before the main performance or during it. When the main performance is a public event, retakes are difficult and so rehearsal is ever more important. But these are not public performances, and I have occasionally detected some continuity glitches in the lectures which suggest that there have been some retakes, but very few. (Lecture 3, segment 4 about 19:15m in)

This is not entirely straightforward. The faultless presentation becomes a "Spiel"--a slick salesman's patter which does not convince, and certainly lacks any sense of the thought and research and scholarship and debate which has gone into the considered and measured judgements of the lecture content. 
But... Academic presentation is not about the presenter, but the content. Sometimes the issue is about the academic superstar's "Look at ME!" obsession (I shall refrain from mentioning names...) This time it is certainly not that, but the way in which personal characteristics just obtrude into the presentation, unintentionally. Whichever way, we return to George Herbert, whom I quoted in the first post in this series--
A man that looks on glass,
On it may stay his eye,
Or, if he pleaseth, through it pass,
And then the heav'n espy.
The challenge for the presenter is to get out of the way so the student can engage as directly as possible with the content/

And that requires conscious and deliberate effort. And if it doesn't happen, it sends a message to the student. You ain't worth it. There are 70k students out there, we are told. The lecturing style of this course so far might pass muster for a couple of hundred students, live in a lecture theatre--where as I have argued, the situation is much richer than on-line. But for 70k students trying to engage with the material without the supporting ambience of a university, and a library... they need so much more. 

I am reminded of a post I wrote but never published from almost exactly a year ago, about an archaeology-themed holiday in Greece with a tour guide who was dire.
He rambled almost incoherently at inordinate length over the PA system on some very long coach rides (600 km on one day), his reading list was hand-written on top of typescript (and the citation was awful), his maps were badly photocopied from some school textbook, it appears... On the final evening, I took him aside and gave him some professional feedback (rising to the challenge of hints from some of the other participants*, and admittedly assisted by moderate wine consumption). I pointed out--much more gently than I would with my own students--that such an unprepared approach communicated effectively to the guests that this kind of job was really rather beneath him, and they weren't worth any greater effort.

It was when he admitted that the maps were not very good, but that he had not had time to get better ones, that I probably overstepped the mark. I reminded him that he had told us this was the sixth time he had done this tour. He rose, said he did not have to listen to any more of this, and walked off.
It's probably just me, with my background and professional interest, but I can't look beyond the presentation and "espy" the academic content. And I can't imagine--well, I can, actually--what it must be like to be a student on this course, where you are being assessed, and it is important that you complete it, and you find yourself approaching each lecture with foreboding... It's not that the experience is so bad, it's that it does not facilitate engagement with the subject-matter, it hinders it. Better not to have it at all.

The other point worthy of comment is the use--or lack of use--made of the assistants, who are brought in very very occasionally to answer questions about the images, with one or two word answers, as a cue for the lecturer to build on. Socratic questioning, it ain't. And the acoustics or sound-rigging make those answers barely audible. This is tokenism.

Sorry to have become so relentlessly negative.

* I do keep falling for this.

On the MOOC -- 2

This is one of a series of posts about participation in the free Massive Online Open Course [MOOC] on the History of the World since 1300 CE, from Princeton U via Coursera. Jonathan Rees, at More or Less Bunk, is also blogging his take on it. I'm sure he has more readers than me, so if you feel like commenting, please do there first--no objection of course to getting his leftovers!

I've now read the recommended material (admittedly in an earlier edition), and "attended" the second lecture.

One of the first issues to strike me (and indeed Jonathan) concerned signposting--ways of helping students to keep track of where they are in the overall argument. There was a lot of verbal signposting in this lecture.
  • "Gold" --we'll come on to that, later
  • "China's approach" --later
...but still no visual depiction.

I wonder why. Indeed, the visual component seems to be deliberately minimal. Now, I hold no truck with the egregiously spurious bulls**t about sensory learning styles. (I hope that is clear!) But I don't really understand why state-of-the-art producers of these courses--and for better or for worse the technical complexity is such that the designer/writer/presenter/producer roles can only be held by the same person with great difficulty--why they don't make elementary use of simple tools.

To be fair, we do get to see the illustrations as free-standing screen images, before the lecturer re-appears and they revert to background, but...
  • The quality is strangely low. We know from the copyright acknowledgement at the end of each segment that most images originate from the textbook, so perhaps we are simply being trailed with images to explore in more depth at our leisure. The images in the textbook, however, are no better. On screen, of course, the potential for zooming in and out on the maps is great, for example--and generalising for a moment, it's really easy and cheap with a package like Prezi. Using the tablet to circle and highlight battles in the expansion of the Ottoman empire is OK, but it could be so much better...
  • And the visual content is unimaginative. I floundered through the first lecture because the time-scale meant very little to me. As Adelman admits, 1300 CE is not an intuitive starting point. So--using a very broad brush--he dipped back into Asian history BCE and up to the high middle ages. That is fine; but it would have been even better with a visualised sub-title or otherwise accessible time-line.
But that poses another question for me; what is the academic level of this course?  It's a big problem for such a course, and I don't want to be critical for the sake of it, but;
  • How much background knowledge can one assume? I've just been watching Wartime Farm on TV. This episode included a reference to children from towns subject to aerial bombing being evacuated to the country, together with film clips, a recollection and some photos from a local person who was a child at the time, and an explanation of how it all worked*. I'm not old enough to remember it, but it was common knowledge in my childhood, and "it made me feel my age" to realise that it would be effectively ancient history to most of the audience, and did need to be spelt out, despite my generation muttering, "Yes, yes! We know all that! Who doesn't?"
  • This is by definition an open-access course, and that means that it will lose people for whom it is too demanding, and also those for whom it is too basic. Adelman promises it will speed up later--when it may well lose me because it expects too much--but for the moment it is frankly boringly slow. 
    • A commenter on the previous post has helpfully pointed out that it is possible to speed up the playback (available via the "keyboard shortcuts" menu at the bottom of the playback window).
  • But that poses another question. Video plays at its own pace. And it is linear (despite Adelman's references to later and earlier lectures). The experience, like that of the lecture hall, is common, although not necessarily shared, when the presentation is virtual. I know in this case that had I had a transcript of the lecture, I would have preferred to have skimmed that, rather than listen to the professor. Do we know what video is more suited to--in terms of level of learning, take a bow Mr Bloom--or discipline? That is a real question--I've just consulted my own library, and not found any answers beyond the thoughts of Laurillard (2001), which are of course way out of date--so all leads gratefully received.
    • Actually, it is possible to access a transcript, in the form of the text for the sub-titles, on the right-hand side of the panel for each lecture segment, but they are unformatted .txt files, and thus difficult to read. I note that there is an announcement about editing and translating those files, dated 20 September. That's brilliant--perhaps someone could edit and format them to reflect the relative importance of topics? (No, sorry, I have other things on!)
  • Somewhere, there was also a point made about the quizzes at the end of each segment, and the lack of guidance about when there was a single acceptable answer and when more than one item could/had to be selected (but I can't find it again). I am not a great fan of multiple-choice examinations of any form, and several posts on the "lectures" forum show their limitations. But I must admit that these have been carefully designed so they are not merely tests of recall, but do require one to think back over the arguments and the less-than-obvious distinctions made in the lectures. The distractors (the suggested wrong answers) are the key to good MCQs, and these are well pitched.
Next time, unless something gets in the way, I'll try to engage with the forums--they are very important, but daunting on a course as big as this...

Jonathan's take--and interesting comments--are here.

On the ultimate campaign ad!

Thanks to Jamie Frevele at Boing-Boing: "While I don't officially endorse Bridget Mary McCormack, who is running for a seat on the Michigan State Supreme Court, I do endorse the viewing of the campaign ad she's running for her non-partisan race. As the sister of actress Mary McCormack, who played security advisor Kate Harper on The West Wing, she was able too hook herself up with her very own reunion of the cast of Aaron Sorkin's presidential series..."



We don't have campaign ads in the UK (unless you count Nick Clegg saying "I'm sorry") but if we had to, I wish they were all like this. (But how did Bartlet get re-elected for a third term, and how did he oust Santos?)

On the MOOC --1

This is one of a series of posts about participation in the free Massive Online Open Course [MOOC] on the History of the World since 1300 CE, from Princeton U via Coursera. Jonathan Rees, at More or Less Bunk, is also blogging his take on it. I'm sure he has more readers than me, so if you feel like commenting, please do there first--no objection of course to getting his leftovers!

Day 1. I am emphatically not planning to live-blog this whole thing, incidentally.

This post is not enthusiastic, and given my track record, I really don't want to become a professional whinger. But writing this, I realise an important distinction--one which I engaged with almost every day when I was assessing the practice of learner teachers--between the perspective of the observer and that of the participant. (Etic and Emic ...sorry!)

Most people who take the course will not give a damn about its design and implementation. They will quite rightly be interested only in what they can learn through it. That preposition is apposite. [I love it when I can be so precisely pompous!] As George Herbert put it:
A man that looks on glass,
On it may stay his eye,
Or, if he pleaseth, through it pass,
And then the heav'n espy.
I'm afraid that although I hope to espy the heaven, I cannot but stay my eye on the glass. And the glass is presumably the most refined, transparent, and distortion-free available.

I have indeed signed up for the course because I am quite interested in the subject, although it is worth noting that I have no extrinsic motivation at all (unless you count acquiring material for this blog).  The course carries no credit, which probably makes some difference to how it is experienced by its participants. But the majority of the 70,000 participants presumably could not care less about the features I shall comment on---until they pass a threshold beyond which they obtrude onto their learning experience.

My problem of course, as it is when I observe direct teaching, is to tell what matters and what does not.

I'm starting from the position that this is the best course its originators can design. It carries the Princeton brand--one of the most prestigious brands in US academe. It's far from an amateur (Khan academy in its early days?) production. I haven't seen a credits list, but I assume that it benefits from the input of very accomplished instructional designers, production staff and online developers.

The preface to the textbook (I wasn't prepared to pay £90 for the latest edition, and settled for £15 for the 2002 version--it arrived today) states:
"For an entire year we met to discuss [...] what global themes we wanted to stress. Only after intensive and sometimes contentious discussions were we able to decide on our over-arching framework, the chapter divisions[...]" (Tignor et al. 2002: xxv)
I'm assuming that a similar vigorous debate took place about the design of the MOOC (although probably not with the same team, and given the shift of focus, perhaps lacking some of the expertise?)

So what we are participating in is probably pretty well what was intended. I'm labouring this point not because I want to beat the authors around the head with what I see as their failures, but because I want to understand why they made the choices they did. This is the state of the art.

Pre-enrolment*

(* the single "l" is correct British spelling.)

I signed up easily, and the course details were accessible and adequate. I don't think the nature of the course contract was as clear as it could have been, in terms of probable time-commitment, assessment load, and so on.

In this case, as a free non-credit-bearing demo course, to emphasise such things could be overkill, and put off some prospective participants, but I noted some anxious questions on the forums---"I'm already juggling work and single motherhood, so I can't be sure I'll get the assignments in on time--can I still sign up?" (A paraphrase of several posts.)
    [Actually--off topic--that's not a problem for the course. The applicant has clearly not understood the nature of the contract. In this case, it is simply a gift. She can take whatever she wants, and there is no obligation in return.
    (Sweeping generalisation without evidence alert) We're not very good at gifts nowadays when they are so exploited commercially as portals to bait and switch deals. Even I feel a little "ungrateful" as I critique (not the same as criticise) this course. One shouldn't look a gift horse in the mouth.]
The confirmation and welcome emails were really helpful, because just as you need to know what room your course is in at college, we need to know precisely where to go (url) actually to start this course. Fortunately, online you can't be late for the first class. The introductory page is clear, welcoming, and instils confidence.

The bottom line.

It's based on video lectures. That's a very conservative approach, and I'm trying to weigh up the considerations which may have been taken into account in going down this route. But a little more detail would be appropriate for any of you who has not signed up for the course;
  • there is one lecturer (Jeremy Adelman)
  • these are not videos of live lectures (I think--there are some token gestures to the audience and a grad. assistant, but the setup is more studio than lecture theatre).
  • the lectures are broken up into 10-15 minutes segments, punctuated by "quizzes"--Adelman admits he does not like the term, but he has put out a rather good explanatory email about them, presumably in response to confusion about how many of the multiple-choice responses can be chosen. Even so, I am struck by the contrast between the pace of this presentation and that of "factual" TV, which covers material about five times as fast, although of course its aspiration is to entertain rather than educate (perhaps--bear in mind that some of the best factual programming on the BBC is supported by the Open University).
  • they are supported with minimal slides, at the rate of roughly one every three minutes. So far they are only maps and pictures--no bullet points, thank goodness. Of course, whether the absence of text-heavy slides reflects a principle about presentation, or a pragmatic acknowledgement that it's not a good idea for an international audience, (or both/neither) I don't know.
  • but--the segments are crude divisions, and there is no sign-posting of topics being addressed--other than verbally. Adelman makes an effort to re-visit his points and itemise them, but without any visual anchors. There is a handout to accompany the first lecture, but it consists solely of a list of names, locations and terms which may be unfamiliar--it gives no guidance on what to expect when.
  • this links, too, to my recognition after a while that I had no temptation to take any notes (partly a reflection of the speed of presentation--see below). One reason for taking notes in a live lecture (at least before they started to be recorded and placed on the VLE) was of course to capture this live one-off moment (at least, for the student!) This time, I knew I could re-visit any time and re-play a segment so perhaps I did not concentrate in the same way. The way in which I did concentrate, however, has swings and roundabouts. 
    • however, the absence of signposting would make it difficult for me to select a point in time to revisit the video for clarification. A continuing sub-title, or a crib-sheet handout showing at what point the lecture moves on to a different sub-topic would have facilitated such re-visiting.
  • a participant commenting on the forums thanks the lecturer for not going too fast--her first language is not English. I appreciate that, but the pace in the first lecture is turgid (Adelman promises it will accelerate shortly). That is not a critical comment aimed at the presentation, just something to bear in mind about lecturing in English to an international and multi-lingual audience.
  • Sub-titles are available, but the synch leaves something to be desired.
So what does that say about the strategy of the course? I can only make inferences, but I need more evidence...

Until later...

On doing a MOOC

Fifteen years ago, I worked with some cutting-edge educational technologists to devise a module on "Resource-Based Learning"  for a Master's course which I directed. I rapidly found that even with small cohorts, the time required to tutor students and join in online discussions vastly exceeded my time allowance (even not counting the initial preparation time).

Ten years ago, a colleague and I launched an online Research Methods module for another Master's in Education, but I conducted mine as a blended course, using an early version of the "flipped classroom" approach as it is now known. Worked well, and was manageable for me, even allowing for a 110-mile round trip to get to the face-to-face sessions Perhaps now we would do it with Skype or similar technology.

And I worked with the UK Open University on developing re-usable interactice "assets" which could be incorporated into online practice-oriented courses in nursing and social care.

Around the same time, I wrote these pieces (here and here) on resource-based learning. I claim a certain  degree of prescience in them. And I've got a record as a designer, author and tutor...

But a few years later, I did an online course on online tutoring, as a student, and blogged it*.

I hated it.

I admired how it had been devised, and particularly the skill and patience of the tutors, dealing with obnoxious participants such as myself. No, to be fair, I was the only obnoxious participant. (The others were, I think, pre-disposed to enjoy/like/value/endorse it, because they [or--more likely--their institutions] had paid to participate. I got it free, as a part of my employment package; it seemed curmudgeonly to turn it down, but I did not approach it with high expectations.)

At the most basic level, all I can remember about it is resenting it. There was apparently some substantive content -- but most of it was about the management of online courses which frankly doesn't have much academic hinterland, and I won't mention the set text, because it was useless. So I'm a sceptic, even a cynic about online learning. Now...

Jonathan Rees (an historian) has long been a concerned observer of online courses on his More or Less Bunk blog. But with the advent of a free CoursEra Massive Open Online Course (MOOC) on World History since 1300 (AD/CE it appears, although it doesn't specify) he is signing up and planning to share his experience through the blog.

So--- Let's join in! OK, the projected time commitment may be a little onerous (but not obligatory), but there are no prerequisites and it is free.

Sign up here.

I shall particularly be interested in:
  • how much difference it makes that the course will be much more information-heavy than stuff I have done previously, and therefore probably more suited to online delivery.
  • the experience of participation and whether and how any sense of community and mutual support develops.
Incidentally, it probably makes more sense to post comments on his blog rather than this one--the bigger the community the better!
