Credentialism and Overexamination

Posted in Biographical, Education with tags , , , , , , , , on September 30, 2012 by telescoper

Only time for a quick post this morning as I have to go into the department to get my things ready for tomorrow, when the Autumn Semester starts and I have to begin lecturing (at 9am on a Monday morning). Anyway, the text for today’s sermon is provided by Ed Smith’s Left Field column in the New Statesman, the latest issue of which I read yesterday. His topic is the rise of credentialism and the resulting excessive amount of examination in the British school system:

It is now widely accepted that British pupils are excessively over-examined. Teachers are so busy focussing on examinations that there is little time left for education. Exam-led cramming has become the year-round norm – like an election campaign that consumes the whole political cycle. Exams are obviously necessary. But there is an optimal amount of assessment and it has been far exceeded. Grade inflation – notwithstanding this year’s controversial “crackdown” – is simply accepted as a fact.

It’s well said, and it’s not just the school system that suffers from disproportionate emphasis on assessment over education. It’s rife throughout the university system too, starting with the reliance on A-level grades as criteria for assessing students’ suitability for university study, through the “modular” undergraduate degree programmes with examinations twice a year for three or four years.

We examine far too frequently and the effect of this has been to turn the entire education system into a meaningless exercise in box-ticking.

It is an unfortunate irony: in our age of credentialism, exams have never mattered more. And yet they have never been more unreliable as gauges of academic quality.

I’ve felt for some time that in my discipline, Physics (and Astronomy) A-levels are virtually useless as indicators of the suitability of a student for doing an undergraduate degree. Some of the very best students I’ve ever had the pleasure to teach came into my university with modest A-level scores; and some students who came in with perfect grades at school never adjusted to the different, more independent type of study required of an undergraduate.

As Ed Smith points out, the increased emphasis on examination grades hasn’t expanded opportunity either.  It may appear to be fairer to base university entrance or award jobs on examination results rather than, say, interviews, but this has just led to a system that can be easily gamed – private tutors, cramming, re-sits to improve grades, and so on. He rightly concludes that the “correlation between exam results and intelligence has been steadily weakening”.

So what’s the alternative? Smith mentions the admissions process at Harvard University, which famously ignores high-school grades and relies on its own interview system. Interviews can be very biased if carried out in an inappropriate way. Subjecting a young person to a 30-minute grilling  in a room with a complete stranger can be enormously stressful for applicants who are shy, and would also play into the hands of those whose educational background has involved specific training for such ordeals. But one thing I’ve found by talking to students face-to-face is that it doesn’t take very long to identify precisely those things that the examination system does not: imagination, enthusiasm for the subject,  and a flair for thinking on your feet:

One teacher told me with regret that she had to advise her most academic pupil not to display her full intellectual range: in order to secure all the ticks, first you have to stop thinking freely.

If you don’t believe this, take a look at this GCSE Science Examination. A truly intelligent student would struggle to find any correct answer for many of the questions on that paper!

This is why we still place so much emphasis on interviews in the postgraduate admissions system: we take it for granted that all applicants for PhD places will have good undergraduate degrees. What marks out an excellent candidate for a position as  research student, however, is not the ability to pass exams but a mixture of creative flair and almost obsessive determination to surmount the difficult challenges involved in independent research. The correlation between these characteristics and degree results is by no means strong.

The problem for a UK University in adopting the Harvard approach is that credentialism is now running the system. Students apply to universities largely on the basis of their predicted A-level grades, lowering their sights if their predicted grades would not be expected to get them into a more “presitigious” department. But departments that take in students with low A-level scores also get marked down in the league tables for taking in “weaker” students. We’re all aware that A-levels are basically useless, but both sides are  bound so tightly into the system that there seems to be no escape.

So what’s the answer? I don’t know if there is one, but I’d love to see what would happen if all universities abandoned A-levels and instead set their own entrance examinations and interviews. It would be a huge amount of work, but it would make a refreshing change if universities could gather useful information rather than relying on the uninformative guff produced by the national examination boards.

And here is Smith’s closing remark that rings very true to me for personal reasons,

There is a further dimension to the problem of credentialism. It encourages life’s winners to underestimate their good fortune and to over-rate the extent to which they deserve their success. Far from advancing talent over privilege, credentialism has strengthened the grip of people already at the top.

A-level Chemistry Examination (Paper 2) from 1981

Posted in Education with tags , , , on September 2, 2012 by telescoper

A few days ago I posted Paper 1 of the Chemistry A-level examination I took way back in 1981. Judging by the blog stats, that seemed to attract a bit of interest so I thought I’d follow it up with Paper 2 which, in contrast to the multiple-choice style of Paper 1, consists of longer questions and perhaps gives a better idea of whether anything has changed between then and now.

Anyway, as usual,  any comments from people who’ve done A-level Chemistry more recently would be very welcome through the Comments Box, e.g. is there anything  in this paper that you wouldn’t expect to see nowadays? Is it easier, harder, or about the same as current A-level Chemistry papers?

A-level Chemistry Examination Paper, Vintage 1981

Posted in Education with tags , , , on August 29, 2012 by telescoper

I don’t know how many followers of this blog are interested in Chemistry, but I thought I’d continue my irregular series of postings of old examination papers with my Chemistry A-level. This particular Paper was Paper 1 of 2 (although I did also take the “special” Paper 3). As you can see Paper 1 was of multiple-choice format, with 40 questions to answer in 75 minutes, which seems a bit stiff! Looking over the exam just now I can’t believe that there was a time when I actually knew this stuff. Nowadays I can only really do the first few questions – because they’re really physics – and I don’t even remember what most of the words mean in the other questions!

Open for Clearing in Physics and Astronomy

Posted in Education with tags , , , , , , , , on August 16, 2012 by telescoper

It being A-level results day, I thought I’d try a little experiment and use this blog to broadcast an unofficial announcement that, owing to additional government funding for high-achieving subjects, the School of Physics and Astronomy at Cardiff University is able to offer extra places on all undergraduate courses starting this September for suitably qualified students.

An institutional review of intake numbers by HEFCW (Higher Education Funding Council for Wales) resulted in the award of extra funded places for undergraduate entry in 2012. Of particular benefit are those STEM (science, technology, engineering and mathematics) subjects seen as strategically important by the UK government. Therefore, the School of Physics and Astronomy is pleased to announce acceptance of late UCAS applications from those candidates expected to achieve our entrance requirements.

Those current applicants who have already applied through the standard UCAS procedure and who have been offered places need not be concerned as these new places are IN ADDITION to those we were expecting to fill.

Applications can be made through Clearing on UCAS after discussions with the Admissions Team.

Course codes (for information)

BSc Physics (F300) and BSc Astrophysics (F511)

MPhys Physics (F303) and MPhys Astrophysics (F510)

BSc Physics with professional placement (F302)

BSc Theoretical and Computational Physics (F340)

BSc Physics with Medical Physics (F350)

Course enquiries can be made to Dr Carole Tucker, Undergraduate Admissions Tutor, via email to Physics-ug@cardiff.ac.uk or call the admissions teams on 029 2087 4144 / 6457.

Good luck!

Post-16 maths - but not as we know it

Posted in Education with tags , , on July 25, 2012 by telescoper

Reblogged from Biomaths Education Network:

The introduction of post-16 maths is in the news again with a report from the House of Lords committee on Higher Education in STEM and many of the headlines from the Guardian, Independent and Times Higher  have picked up on the recommendations regarding maths study post-16.

I have written a few thoughts here on my first impressions but would very much welcome comments.

Interesting view from a Biosciences perspective about the recent recommendations to increase the number of students taking Mathematics at A-level. I've always had a problem with the way Statistics is taught at A-level, which is largely as a collection of recipes without much understanding of the underlying principles; would more emphasis on probability theory be a better way to go?

By Gove, I agree!

Posted in Education with tags , , , on April 4, 2012 by telescoper

I never thought the day would come, but I have to admit it. I agree with Michael Gove. There. I said it.

Not with everything he says, of course. But I do think that universities should take over responsibility for the examinations required for University Entrance, currently known as A-levels. Here is an excerpt from an old post on this, and I’ve said much the same thing on several other occasions:

So what’s the solution? I think it is to scrap A-levels entirely, and give the system of pre-university qualifications over to the people who actually know what students need to know to cope with their courses, i.e. the universities. There should be a single national system of University Entrance Examinations, set and moderated by an Examination Board constituted by university teachers. This will provide the level playing field that we need. No system can ever be perfect of course, but this is the best way I can think of to solve the biggest problem with the current one. Not that it will ever happen. There are just too many vested interests happy with the status quo despite the fact that it is failing so many of our young people.

But lest you all think I’ve turned into a Conservative, let me point out that the fault with the current system is precisely that market forces have operated to the detriment of educational standards. The GCE examination boards compete for customers by offering easier and easier examinations each year, regardless of what students need to know to cope with University courses. What I advocate is renationalisation.  I bet Mr Gove doesn’t like it put that way…

Oh and another thing. I think universities should be given this task, but should also be paid for doing it just as the examination boards now are. That way it will not be treated as yet another imposition from the top, but an important task that has a similar status within a university as teaching and research.

A-Level Further Mathematics Examination, 1981

Posted in Education with tags , , on October 24, 2011 by telescoper

I’ve been forcibly evicted from my office this afternoon while a highly-trained operative of Cardiff University’s esteemed Estates Department replaces a broken window. It’s been broken since I moved into the office, about four years ago, by the way, but you can’t rush these things. Anyway, having been forced to change location I took the opportunity to decamp to the upstairs computer room wherein our departmental scanner resides and occupied myself with the task of scanning in yet another of the old examinations I took when I was in school. This one is the Further Mathematics examination, consisting of two papers each of three hours’ duration: Paper 1 is entirely Pure Mathematics; Paper 2 contains a mixture of Pure and Applied Mathematics, and Statistics.

Looking back on the paper now, thirty years after I first saw it, it seems to me that the Applied Mathematics questions (6-11 on Paper 2) actually look quite tough by the standard of 1st year undergraduate examinations in mechanics. However, I’ll leave it to you to comment on whether you think it’s harder, or easier, or about the same, compared to current A-levels in Further Mathematics. I’d also be interested in knowing whether there’s anything on these papers that isn’t on the syllabus nowadays.

The comments box awaits…

An A-level Physics Examination Paper, Vintage 1981

Posted in Education with tags , , , on September 1, 2011 by telescoper

At the risk of becoming one of the Great Bores of the Day on the subject of past examinations I thought I’d follow up  my old O-level Physics paper  with a Physics A-level examination paper to see what people think about it. It might add to the discussion over on another blog I read too.

I took this particular examination myself in 1981. Can it really be 30 years ago? Agh. Paper 1 comprised a collection of short questions of multiple-choice type from which I’ve already posted one example on this blog.  This one is Paper 2 and, as you’ll see, it consists of longer questions with a freer format.

One comment I’ll make is that Question 5 is remarkably similar to a coursework questions we have been using here in the School of Physics & Astronomy at Cardiff University in our First year Physics module on Electricity and Magnetism.

Any other comments from people who’ve done A-levels more recently would be very welcome through the Comments Box, e.g. is there anything  in this paper that you wouldn’t expect to see nowadays? Is it easier, harder, or about the same as current A-level physics papers?

An easy physics problem…

Posted in Cute Problems with tags , , , on May 26, 2011 by telescoper

Based on the popularity of something I posted last week, I thought some of you might find this little problem amusing. It’s from a Physics A-level paper I took in 1981. The examination comprised two papers in those days (and a practical exam); one paper had long questions, similar to the questions we set in university examinations these days, and the other was short questions in a multiple-choice format. This is one of the latter type, from the mechanics section.

And here is a poll in which you may select your answer:

Disturbing Admissions

Posted in Education, Politics with tags , , , on January 18, 2011 by telescoper

In a rare moment of wakefulness during yesterday’s Board of Studies, I listened to a report from our departmental admissions tutor about the state of play with applications for entry onto our physics courses next year. It was good news – applications are up more than 50% on last year – but this was tempered by the fact that our quota has gone down slightly, owing to the presence of a cap on student numbers. I’m not sure whether the increase, perhaps caused by students trying to get into university before the fee  goes up to £9K, is echoed around the country, but it seems likely that competition for places will be intense this year, with the almost certain result that many students  will be disappointed at being unable to get into their first choice university.

Coincidentally, I noticed a story on the BBC at the weekend suggesting that the whole timetable of university admissions might change. What the government is planning remains to be seen, but there’s no doubting the system is far from perfect and if we had the opportunity to design a process for university admissions from scratch, there is no way on Earth we would end up with a system like the current one.

As things stand, students apply for university places through UCAS before they have their final A-level results (which don’t come out until July). Most applications are in by January of the year of intended admission, in fact. The business of selecting candidates and making offers therefore makes use of “predicted grades” as supplied by teachers of the applicant.

According to the BBC news

..under the current system those from poorer backgrounds typically have their grades under-predicted.

I simply don’t know whether there is any information to back this up – in my (limited) experience most teachers systematically overestimate the grades of their pupils – but if it is the case then it would be a good reason for changing the timetable so that potential students could apply once they have their results in the bag. They can do that now, of course, but only if they take a gap-year, applying for admission the year after they have their A-levels.

But the inaccuracy of predicted A-level grades is not the only absurdity in the current system. Universities such as Cardiff, where I work, have to engage in enormous amounts of guesswork during the admissions process. Suppose a department has a quota of 100, defining the target number students to take in. They might reasonably get a minimum of 500 applications for these 100 places, depending on the popularity of university and course.

Each student is allowed to apply to 5 different institutions. If a decision is made to make an offer of a place, it would normally be conditional on particular A-level grades (e.g. AAB). At the end of the process the student is expected to pick a first choice (CF) and an insurance choice (CI) out of the offers they receive. They will be expected to go to their first choice if they get the required grades, to the insurance choice if they don’t make it into the first choice but get grades sufficient for the reserve. If they don’t make either grade they have to go into the clearing system and take pot luck among those universities that have places free after all the CFs and CIs have been settled.

Each university department has to decide how many offers to make. This will always be larger than the number of places, because not all applicants will make an offer their CF. We have to honour all offers made, but there are severe penalties if we under or over recruit. How many offers to make then? What fraction of students with an offer will put us first? What fraction of them will actually get the required grade?

The answers to these questions are not at all obvious, so the whole system runs on huge levels of uncertainty. I’m amazed that each year we manage to get anywhere close to the correct number, and we usually get very close indeed by the end.

It’s a very skilled job, being an admissions tutor, but there’s no question it would all be fairer on both applicants and departments to remove most of the guesswork.

But there is the rub. There are only two ways I can see of changing the timetable to allow what the government seems to want to do:

  1. Have the final A-level examinations earlier
  2. Start the university academic year later

The unavoidable consequence of the first option would be the removal of large quantities of material from the A-level syllabus so the exams could be held several months earlier, which would be a disaster in terms of preparing students for university.

The second option would mean starting the academic year in, say, January instead of October. This would in my opinion be preferable to 1, but would still be difficult because it would interfere with all the other things a university does as well as teaching, especially research.  The summer recess (July-September), wherein  much research is currently done, could be changed to an autumn one (October-December) but there would be a great deal of resistance, especially from the older establishments; I can’t see Oxbridge being willing to abandon its definitions of teaching term! And what would the students do between July and January?

The apply-after-A-level idea has been floated before, about a decade ago, but it sank without trace. I wonder if it will do any better this time around?
