The Week Ahead

Posted in Biographical, Covid-19, Education, Maynooth with tags , on August 23, 2020 by telescoper

On Friday I finished correcting the batch of Repeat examinations that were within my remit. I think the other staff have done likewise. All the marks now get uploaded and cross-checked and before another meeting of the Exam Board the year’s examination process to an end.

There’s no time to pause, however, as we go straight into the preparations for next academic year. Nobody knows quite how things are going to go, and no doubt we’ll have to adapt quickly to changes in the national situation. County Kildare, wherein Maynooth is located, remains in a sort of mini-lockdown for the next two weeks. It is not a very welcome distinction to be in the only County under “special measures” – Laois and Offaly – were stood down on Friday – but I’m optimistic that local Covid-19 outbreaks will be sufficiently well controlled to let us relax fully well before term starts.

At least after the Repeats we will know how many returning students we have on which modules so can start firming up the arrangements for Years 2 to 4.

Year 1 will have to wait for the Leaving Certificate results which won’t be out until after September 7th. Teaching starts on 28th September so final arrangements for new students will have to be made at the last minute. As it happens I’m teaching the first module for Mathematical Physics. I have a basic a plan of what I want to do but the details are dependent on precisely how many students we have.

For new students there is an Orientation Week before teaching starts which this year will be virtual, so in preparation for that I’ll be recording video presentations for the new students on different courses. They all have to be done by Wednesday.

There’s also sorting out contracts for tutors, training on new software and hardware for teaching, and writing lecture notes to be getting on with.

On top of all that, if there are no last minute hitches, I should be getting the keys to my new home on Wednesday so will be moving in later in the week. I have paid this month’s rent on the flat so have until the end of the month to move out. I can therefore do a relatively gradual transition over a few days, working around work commitments. Not that I have much to move: a lot of my personal effects are still in Wales and there’s no way I can get back retrieve them at the moment. Although the timing could have been better, I’m looking forward to living in a home of my own once more.

O-Level Latin Examinations, Vintage 1979

Posted in Biographical, Education with tags , , , , , , on August 20, 2020 by telescoper

Since I’ve just finished marking all my repeat examinations, and examinations are in the news for other reasons, I thought I’d fish out one of the GCE O-level examinations that I took way back in 1979 when I was 16. I have from time to time posted examinations in Mathematics and Science subjects at both O-level and A-level, but I thought it would be fun to share something quite different. In fact my best mark at O-level was in Latin. Latin was a compulsory subject at my (old-fashioned) Grammar School, by the way.

The first of the two Latin exams was basically about the language, and involved unseen translation and comprehension tests. The second involved parts of two set books. We did Book II of Virgil’s Aeneid, a verse epic in strict hexameter, and Book V of Caesar’s Gallic Wars De Bello Gallico. These formed Sections A and B of the same examination although they appear as separate papers. The bit of the Aeneid we did included the Trojan Horse (actually Greek Horse, obviously) and the famous line `Timeo Danaos et dona ferentes’…

The GCE O-levels were replaced by GCSEs a few years after I did mine and I’m not sure how many people do Latin at GCSE these days (or indeed at Leaving Certificate) but I’d be interested in any comments on how these exams compare with modern ones!

The U-turn and After …

Posted in Education, Politics with tags , , , on August 18, 2020 by telescoper

One of the many things that Winston Churchill never said (referring to Americans) is that they “…will always do the right thing – after exhausting all the alternatives”. Yesterday the UK Government performed a U-turn on its approach to A-level results but only after extensive protests and after causing immense stress to a great many students. All of this could have been avoided had the Secretary of State for Education bothered to look at the results of the downgrading algorithm. This morning he said that he “wasn’t aware” of what the outcomes would be and tried to put the blame on OfQual. Well, it’s actually his job to be aware of these things and that statement shows he’s not doing his job.

While many students will be mighty relieved that their official A-level grades will go up, that won’t be the end of this fiasco. Many students will find that their places have been already been filled through last week’s clearing process. The Government has lifted the number cap on places in imposed earlier this year, but that won’t help many departments, especially those in the sciences, who have severe constraints on, e.g., laboratory capacity (more so with social distancing in place).

I feel very sorry for friends and former colleagues in UK universities having to deal with this shambles. The Government will be quite happy that it has managed to throw this particularly hot potato into the hands of admissions tutors across the land. Ministers will be hoping that whatever blame now accrues will be attributed to universities being “inflexible” when it is entirely down to incompetence elsewhere. As always it’s the front-line staff who will have to deal with it, as if their job was not stressful enough having to deal with Covid-19.

Meanwhile, here in Ireland, the Government’s plan for “standardisation” of this year’s Leaving Certificate results looks alarmingly similar to the failed approach tried – and subsequently abandoned – in the United Kingdom. Minister for Education Norma Foley has been making statements about the accuracy and reliability of her Department’s plans that sound eerily similar to those issued by officials across the Irish Sea. I hope that I’m wrong about this – and that there’s some frantic activity going on behind the scenes to change the approach ahead of the release of this year’s Leaving Certificate grades (due on September 7th) – but I have a feeling that we’re going to see yet another slow-motion car crash. It wouldn’t be the first time that, having observed something truly shambolic happening in the UK Education system, an Irish Government then proceeds to do exactly the same thing…

The Great A-level Scandal

Posted in Education, Politics with tags , , on August 14, 2020 by telescoper

The full scale of the scandal of this year’s A-level results is now becoming clear and it is bad enough to bring down a Government. Unfortunately there are so many scandals surrounding the UK Government (e.g. corrupt procurement deals, collapsing economy, terrible Covid-19 mortality figures, fiddled Covid-19 testing statistics, not to mention Boris Johnson himself) that nobody seems to care about that one more probably won’t make much difference.

Yesterday Qfqual released its report on this year’s A-level results which reveals that in arriving at the final grades, the algorithm deployed was based on past performance of pupils at the candidate’s school. in many cases this has resulted in students being downgraded by several grades in a manner that is both arbitrary and cruel.

Update: I’ve just heard from a physics, in an institute in which I once worked, that a student with original grade A* in Physics A-level has been assigned a final grade E. Unbelievable.

That starting point of the Ofqual approach is indefensible. A student’s examination grade should be determined by the student’s own performance, not by the performance of previous generations of students who happened to go to the same school at some time in the past.

Not surprisingly, the Ofqual approach has benefited students who went to private schools and severely disadvantaged students at less privileged establishments. The rightwing media are justifying this on the grounds that teachers at some state schools have inflated their students’ estimated grades. The attitude is that working class kids can’t possibly deserve an A* so their teachers must have cheated! I can’t believe this bias is unintentional. The Tory message to the less privileged is that they need to know their place. You needn’t ask who is behind this deliberate demographic* profiling. It stinks of the unofficial Prime Minister Dominic Cummings

But even within its own flawed terms the Ofqual algorithm is garbage. Table E8 in the report shows that when applied to last year’s input data (mock exams and centre-based assessments), even in the best case subject (History) the prediction was only accurate for 67% of students; the figure falls to less than 50% for, e.g., Further Mathematics. When the Ofqual panel saw that they should have abandoned their algorithm immediately. The fact that they pursued it knowing how deeply problematic means that they are more interested in serving their political masters than the students whose prospects they have deliberately blighted.

In my view a system should be introduced that gives the student the benefit of the doubt. Grades should be awarded based on what the student has achieved. If that ends up being too generous to a few students then that’s surely better than the opposite? Whenever I’ve been involved in University examinations processes when emergency changes were required we have always implemented a `no detriment to the students’ policy. It’s the obvious fair thing to do.

Oh, and you might ask why universities don’t show some humanity and accept students whose grades have been reduced. The answer to that is simple. If they do, they will go down in the league tables. And for many senior managers that’s all that matters.

*which means, of course, (indirect) racial profiling too.

Disturbing Admissions

Posted in Education, Maynooth with tags , , , on August 13, 2020 by telescoper

So, as the second day of Repeat Examinations at Maynooth University gets under way, students in the United Kingdom are receiving their A-level results. I’ve already heard a number of stories from friends and colleagues flabbergasted by the way some marks have been treated, so it all looks likely to be quite a mess. I have great sympathy for the students, for whom this has been an extraordinarily difficult year, and I hope the A-level fiasco doesn’t affect too many too badly.

My experience of over 30 years teaching in UK universities has convinced me that A-levels are not a very good preparation for higher education anyway and the obsession with them is rather unhealthy. Some of the best students I’ve ever had the pleasure of teaching came to University with poor A-level grades (for a variety of reasons).

In fact I’d go as far as to say that the entire system of University admissions in the United Kingdom needs to be overhauled. As I said in a post almost a decade ago:

…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.

Of course I longer work in the UK so there’s no longer a “we”, but the system in Ireland is not that much different, with the Leaving Certificate playing the role of A-levels for the vast majority of students.

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

In my (limited) experience most teachers systematically overestimate the grades of their pupils, which is presumably why so many of this year’s A-level results are being downgraded, but there are lots of unconscious biases at play here and I accept that some teachers may be unduly pessimistic about their students likely performance.

But the inaccuracy of predicted A-level grades is not the only absurdity in the current system. Universities 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. They have to honour all offers made, but there may be penalties if they under or over recruit. How many offers to make then? What fraction of students with an offer will put you 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 any institution manages 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 by which I mean allowing students to apply to University after they have got their results. But there is the rub. There are two ways I can see of changing the timetable to allow this:

  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 September. 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 (September-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?

Either of these options would cause enormous disruption in the short-term, which is presumably why they have never been implemented. However, this year everything is disrupted anyway so there’s an opportunity to redesign the whole process. Delaying the start of the academic year until January 2021 would make a great deal of sense this year in particularly, though I think it’s a bit late to be doing it now.

I don’t really imagine the Government is thinking of doing this but here are some suggestions of elements of a new admissions system:

  • Students to apply after receiving A-level* grades (i.e. implement 1 or, preferably, 2 above)
  • All university applications to be anonymous to prevent discrimination.
  • The identity of the applicant’s school to be withheld to prevent undue influence.
  • Teachers to play no part in the process.

*I don’t think A-levels are fit for purpose so here I mean grades of whatever examination replaces them.

Marginalia

Posted in Cute Problems, Education, The Universe and Stuff with tags , , , , , on August 12, 2020 by telescoper

While this morning’s repeat exams were going on I was leafing through an old second-hand text book, one of many I have acquired over the years looking for nice problems and worked examples. The good thing about old books is that solutions to the problems are usually not available on the internet, unlike modern ones. The book concerned this morning is a classic: Statics by Horace Lamb, which you can still get via Cambridge University Press. I have the first edition, published in 1912.

Looking through I was somewhat alarmed to see what had been pencilled in some of the margins:

Of course anyone who has been to India knows that the swastika isn’t necessarily a Nazi symbol: you find it all over the place in the Indian sub-continent, where it is used as a symbol for good luck. I remember being given a very nice conference bag in Pune many years ago with a swastika on it. I didn’t use it back home, of course.

The first owner of the copy of Statics that I have was acquired in 1913 by a J.H.C (or G) Lindesay of Sidney Sussex College, Cambridge. I know because he/she inscribed their name in the front. That doesn’t look to me like an Indian name, but I think it’s a fair bet that the book passed through many hands before reaching me and that one of the past owners was Indian. I haven’t tried any of the problems marked with the swastika, but perhaps they are difficult – hence the `good luck’ symbol? I notice though that the symbol at the bottom of the page has a chirality different from the others. Is this significant, I wonder?

All of which irrelevance reminded me of an discussion I’ve had with a number of people about whether they like to scribble in the margins of their books, or whether they believe this practice to be a form of sacrilege.

I’ll put my cards on the table  straightaway. I like to annotate my books – especially the technical ones – and some of them have extensive commentaries written in them. I also like to mark up poems that I read; that helps me greatly to understand the structure. I don’t have a problem with scribbling in margins because I think that’s what margins are for. Why else would they be there?

This is a famous example – a page from Newton’s Principia, annotated by Leibniz:

dsc00469

Some of my friends and fellow academics, however, regard such actions as scandalous and seem to think books should be venerated in their pristine state.  Others probably find little use for printed books given the plethora of digitial resources now available online or via Kindles etc so this is not an issue..

I’m interested to see what the divergence of opinions is in with regard to the practice of writing in books, so here’s a poll for you to express your opinion:

Examination Shenanigans

Posted in Covid-19, Education, Maynooth with tags , , , on August 12, 2020 by telescoper

So here I am in my office while the first batch of our repeat examinations gets under way here in Maynooth. They seem to have started correctly so I’ve taken a break to have a cup of coffee and catch up on the news.

I find that examinations seem to be making headlines in the United Kingdom. First there was a to-do and a hoo-ha in Scotland that resulted in school examination results that had been downgraded being upgraded again. The downgrading involved using some sort of statistical model to `correct’ teacher-assigned grades and coursework but this model apparently generated significant anomalies.

Then, not to be outdone by the Scots, the English government has announced that estimated A-level grades, presumably obtained by a similar process to that deployed in Scotland, were to be upgraded too. Or not. It seems they will get the original grades but be able to appeal the results.

Writing in today’s Daily Telegraph, presumably without irony, Gavin Williamson explains the decision not to upgrade A-level results automatically:

Increasing the A Level grades will mean a whole generation could end up promoted beyond their abilities.

Gavin Williamson wrote that. Gavin Williamson.

Universities in the UK receive A-level results a few days before the students in order to make admissions decisions, but this year the results students eventually receive may differ from those the universities got. I can imagine the chaos this is causing behind the scenes.

If I understand correctly the new `Triple Lock’ on A-level results means that a student’s grade will be whichever is the highest of:

  • their mock exam result;
  • the grade estimated by their teacher;
  • an A*.

(OK, I made up that last bit.)

Some people think this approach might lead to grade inflation, but I imagine the authorities are less concerned about that than they are by the prospect of getting sued.

Another issue with the downgrading/upgrading situation is that students who took the International Baccalaureate (IB) and have received algorithmic grades have not had their grades increased, which seems to put them at a disadvantage with respect to students who took A-levels and may cause them to miss out on UK university places.

Meanwhile, here in Ireland, we await the School Leaving Certificate results. These are not due until 7th September but I think the plan is to moderate them as in the United Kingdom. Delaying these results gives Ireland the chance to learn from the UK but whether the process will end up being any fairer here is anyone’s guess!

On the Eve of the Repeats

Posted in Covid-19, Education, Maynooth with tags , , on August 11, 2020 by telescoper

I won’t deny that I was caught on the hop by Friday’s sudden announcement of a partial lockdown in an area that includes Maynooth but at least we’ve had a couple of working days to activate Plan B and get all the online assessments ready to replace the repeat examinations that were due to start on campus tomorrow.

Happily all the necessary supports were provided quickly over the weekend and I think we’re now ready to go, with the first paper(s) starting tomorrow morning at 9.30am. There will be several of these per day for the next week or so so it’s going to be a busy period supervising them (remotely) and then marking the scripts when they’re finished. At least we have now got some experience of these tests, having done these before (in May). There are also fewer candidates for the repeats than first time round so it should all be manageable.

When the repeat exams are all marked and the Exam Board finished, we should have a firm idea how many students are progressing to the next academic year so we can draw up plans for lectures and tutorials in September.

Apart that is for the first year, where we won’t know the numbers until September. That will cause a bit of a rush but I’m sure we’ll manage.

All of this assumes that we are doing on-campus teaching in September, which would require the local lockdown to have been lifted. If not we’ll have to do everything online, including tutorials. A ray of hope is that the number of new cases is just 35 today, down from 174 on Saturday, but we’ll have to have nany more days like that to feel secure. We’ll just have to wait and see.

Returning to Campus

Posted in Covid-19, Education, Maynooth with tags , , on August 7, 2020 by telescoper

It’s been a busy day (so far) putting the finishing touches to return to work planning at the Department of Theoretical Physics at Maynooth University. We have improved the signage and decluttered the main corridor to allow the two-way system to operate.

We’ve also fitted the odd tensor barrier (that’s what the above thing is called) to prevent people wandering into offices uninvited contrary to social distancing requirements.

As well as all that I’ve received delivery of a selection of face masks, hand gel and disinfectant wipes.

All this is because the repeat examination period starts next week and we’re consequently preparing for the second wave (of examination marking) by allowing staff to come onto campus to collect their scripts, which most should be able to do from next week.

Update: owing to the recent increases in Covid-19 cases in Kildare Offaly and Laois, as of this evening, local restrictions have been imposed on these counties. As a consequence the return to work process has been paused and all repeat exams scheduled to take place on campus will be replaced by online timed assessments. Sigh.

Implementation Guidelines for Public Health Measures in Higher Education Institutions

Posted in Covid-19, Education, Maynooth with tags , , , on August 6, 2020 by telescoper

Yesterday I was speculating out loud about where we go from here in order to return to teaching in September. Today I find that there’s actually a guidance document produced by the Irish Universities Association under the auspices of the Health Service Executive. The full document (PDF, 12 pages) can be found here.

The advice focuses on principles rather than practice and a lot of work will have to be done in individual institutions to translate the guidelines into working procedures, but it is welcome nonetheless. I encourage everyone involved in higher education to read it all.

A key issue on everyone’s mind concerns on-campus teaching, so I have selected this paragraph:

This suggests that the social distancing between staff and students and between staff and other staff should be kept to 2m but the spacing between students in lecture theatres, laboratories, etc can be 1m with the proviso that students wear face masks.

Note however that there is a more general restriction that indoor gatherings should involve no more than 50 people. Unless some sort of exemption is granted for HEIs then this, rather than social distancing, may determine the maximum class size.

Allowing us to populate rooms with one metre spacing between students rather than two makes a huge difference to our ability to accommodate students in lecture halls and other teaching spaces, but even so the capacity of most teaching rooms will be much lower than normal. For example, the room I taught my first-year class of ~85 in last year has a nominal capacity of 90. With 1m social distancing that is reduced to 27; with 2m distancing it is down to 18. I don’t know how many students I’ll have next semester, but hopefully it will be more than 27! Assuming that it is, I won’t be able to teach them as a single group.
