Examinations and Memory

Posted in Biographical, Education with tags , , on March 5, 2023 by telescoper

This Sunday evening I take the text for my sermon from a piece about examinations by Katie Stripe in the Times Higher about examinations:

Testing students’ ability to show their learning in a closed context is not preparing them for a future in which technology is ubiquitous. There are few professional contexts that require you to recall information in a specific time frame.

I agree to some extent with the conclusion of the article but for different reasons. In particular, I don’t think this conclusion has much to do with the arrival of new technologies such as ChatGPT. Exams that simply require the students to “recall information” and nothing else seem to me to be of limited value from an educational point of view and should indeed be scrapped, but I think exams can play a role in testing other, more important, skills such as problem-solving.

Over my lifetime the ratio of assessment to education in universities has risen sharply, with the undeniable result that academic standards have fallen especially in my own discipline of physics. The modular system encourages students to think of modules as little bit-sized bits of education to be consumed and then forgotten. Instead of learning to rely on their brains to solve problems, students tend to approach learning by memorizing chunks of their notes and regurgitating them in the exam. I find it very sad when students ask me what derivations they should memorize to prepare for examinations because that seems to imply that they think their brain is no more than a device for storing information. It became clear to me over the years that school education in the UK does not do enough to encourage students to develop their all-round intellectual potential, which means that very few have confidence in their ability to do anything other than remember things. It seems the same malaise affects the Irish system too.

On the other hand, a good memory is undoubtedly an extremely important asset in its own right.

I went to a traditional Grammar school that I feel provided me with a very good education in which rote learning played a significant part. Learning vocabulary and grammar was an essential part of their approach to foreign languages, for example. How can one learn Latin without knowing the correct declensions for nouns and conjugations for verbs? But although these basic elements are necessary, however, they are not sufficient. You need other aspects of your mental capacity to comprehend, translate or compose meaningful pieces of text.

The same considerations apply to STEM disciplines. It is important to have a basic knowledge of the essential elements of mathematics and physics as a grounding, but you also need to develop the skill to apply these in unusual settings. I also think it’s simplistic to think of memory and creative intelligence as entirely separate things. I seems to me that the latter feeds off the former in a very complex way. A good memory does give you rapid access to information, which means you can do many things more quickly than if you had to keep looking stuff up, but I think there’s a lot more to it than that. Our memories are an essential part of the overall functioning of our brain, which is not  compartmentalized in such a simple way.  For example, one aspect of problem-solving skill relies on the ability to see hidden connections; the brain’s own filing system plays a key role in this.

In recognizing the importance of memory I don’t mean that rote learning is necessarily the best way to develop the relevant skills. My own powers of recall are not great – and are certainly not improving with age – but I find I can remember things much better if I find them interesting and/or if I can see the point of remembering them and/or if I use them a lot. Remembering things because they’re memorable is far easier than remembering because you need to remember them to pass an examination!

Anyway, my point is that a good memory can help you learn, but is not in itself what should be assessed in an examination. I wish universities made more effort to educate students to understand that their brain can be much more than a memory device.

Here endeth the lesson.

State Supports for PhD Researchers

Posted in Education, Maynooth with tags , , , on February 27, 2023 by telescoper

By sheer coincidence, the very same day that I posted a piece in which complained that the issue of PhD stipends for Irish postgraduates had apparently been “kicked into the long grass”, the consultation has at last opened.

Raising PhD Stipends

Posted in Education, Maynooth, Politics with tags , , on February 24, 2023 by telescoper

Although the Irish Government has kicked its planned review of postgraduate support into the long grass, the Board of Trinity College Dublin recently approved a proposal to increase stipends to for all its PhD students to €25,000. I applaud this decision, but would argue that it doesn’t go far enough.

A while ago Government of Ireland announced a new scheme intended to recruit “high-level researchers” to PhD programmes in Ireland. This scheme, which is a public-private partnership of around  €100 million, will fund around 400 PhD studentships with an annual stipend around €28K, which is substantially higher than the current rate for, e.g., ICR-funded students which is €18.5K. The justification for the higher €28K stipends is that they would be “in line with financial supports offered under similar global scholarships”. I take this as a statement that the Irish Government has acknowledged that the proper rate of pay for a PhD student is at this level, which seems to me to be about right. It seems to me to be logical that all PhD stipends should be increased to this level.

High levels of inflation are combining with spiraling rental costs to make it very difficult for a student to live on the current level of stipend (especially in the Greater Dublin area). This forces postgraduate students to undertake large amounts of tutoring or other work in order to get by financially. This situation is a direct result of the chronic underfunding of higher education in Ireland which means that there aren’t enough academic staff to cover the teaching required. Universities will argue that they don’t have any choice but to exploit PhD students to make up the shortfall, but that doesn’t make the situation is acceptable.

It is of course good for a research student to get some teaching experience during their PhD but this should be on a voluntary basis. A PhD student who chooses to teach will probably do a better job than one who is forced to do it in order to pay the rent. My basic point, though, is that a full-time research student should be funded to do research full time, and it is grossly unfair to pay them too little for this to be possible.

There needs to be a serious “levelling up” of PhD stipends across the entire third-level sector in Ireland. I hope in particular that my own institution, Maynooth University, will take the lead and increase its PhD studentships to the fair level of €28K per annum. This would be a good way to spend at least some of the surplus of €13.2M it ran up during the first year of the pandemic alone.

UPDATE: The Government has now opened a consultation on PhD supports to which you can contribute here.

Early Morning Lectures

Posted in Biographical, Education, Maynooth on February 23, 2023 by telescoper

I saw this doing the rounds on Twitter the other day. I even made a little joke about it which went viral (by my standards) with over a million views and almost 2000 retweets:

There’s no accounting for taste.

Am I a meme now?

Anyway, I’m in the office quite early this morning ahead of my 9am Computational Physics lecture so thought I’d do a quick post. I realize that 9am is not early compared to practice in some institutions abroad where lectures can start at 7.30am or even earlier. Everything I say here is based on my own experience and is not claimed to be universal.

As a lecturer I don’t mind 9am lectures at all. I find itt’s nice to get something significant done before 10am as opposed to just trying to deal with emails. On the other hand, I live only about 20 minutes’ walk away from campus so I don’t have to get up especially early. As a matter of fact I get up at 7am on weekdays, so no real adjustment is necessary for a 9am start. If I had a two-hour commute it would no doubt be a different matter.

At conferences and so on, I don’t find myself sleeping in the morning sessions. I find the slots immediately after lunch the worst for staying awake. That’s the time we have our theoretical physics seminars at Maynooth, actually.

My own experiences of being an undergraduate student (at Cambridge) was that I had regular 9am lectures 6 days a week (Saturdays included) and didn’t mind those either. But Cambridge is relatively compact and, living in College, it didn’t take me long to get to the lecture theatres in town. I usually felt quite sharp at 9am, actually, probably less so later in the morning.

Of course the reality is different for many students, some of whom have lengthy journeys into campus on not-entirely reliable public transport, so find a 9am start a challenge (to say the least). It’s certainly not unknown for students to doze off, but I don’t mind that as long as they don’t snore too loudly. I try to break up these lectures with things for the students to do, and that sometimes wakes them up again. In terms of attendance it’s the early evening slots that are worse in my experience than early morning.

Anyway, here in Maynooth we teaching staff have no real say over timetabling so now I should head off to Hall C to set up.

UPDATE: I had a pretty full class but one student did doze (without snoring) for about 3 minutes.

Three weeks in…

Posted in Biographical, Education, Maynooth on February 17, 2023 by telescoper

The first quarter of the second Semester at Maynooth University has flown by. I’ve now done three weeks of lectures and even conducted the first class test in the computer lab. It is from the correcting of these submissions that I am now taking a short break to compose this blog.

Amazingly, for the first time ever, there have been no major problems in the Computational Physics lab at all. In previous years, something has always gone wrong but not (so far) this time round. I’m sure our nice new digital display screen has also improved the experience for the students in that they can now actually see the instructions I give them!

I’m actually ahead of the game in my Advanced Electromagnetism module, having done 7 lectures in 3 weeks instead of the usual 6, because I used one of my tutorial slots to give an extra lecture, anticipating that I’d lose a lecture on Good Friday (7th April) as this is a national holiday in Ireland. The following week is a holiday here too. Three weeks from now we have the mid-term Study Break (13th-17th March, ending on St Patrick’s Day), so after the first six weeks of this Semester we get a little more time to relax.

Soon it will be time to write the examinations for Semester 2. I need to think up some questions for Advanced Electromagnetism and Computational Physics. Writing an examination takes the same time regardless of how many students are taking it, but when the class sizes are small it takes much less time to do the marking. There is a large component of continuous assessment in Computational Physics, which means more work for me through the term, but there are only 25 in the class so it’s not too bad. The class for Advanced Electromagnetism is even smaller, which should make my marking workload in June a bit less heavy than it was in January.

Today students were notified of their provisional Semester 1 examination results. I expect I’ll be talking to some of them next week to discuss their options in the light of the outcome. Final marks don’t get confirmed until the Summer, when we have a full meeting of the Examination Board together with the External Examiner. Marks don’t usually change but they can if the Board decides they should.

We often have a seminar on Friday afternoons but we don’t have one today which is why I’ve got time to write this post. Often I go to the National Concert Hall on Friday evenings but I’m not going this evening. I decided to have a quiet night in tonight, as I’ve got something important to do tomorrow. After I finish marking this first class test I think I’ll toddle off home.

Solidarity to the UCU Strikers #UCURising

Posted in Education with tags , , , on February 14, 2023 by telescoper

Today is Thursday 14th February so it sees the first of another three consecutive days of strike action by members of the University and College UCU across the UK over pay, pensions and working conditions. Although I no longer work in the UK I’d like to send this message of support to my former colleagues there who will be out on the picket lines today. There will be another three days of strikes next week, and four days the week after that.

Today is Thursday 9th February so it sees the first of another two consecutive days of strike action by members of the University and College UCU across the UK. Although I no longer work in the UK I’d like to send this message of support to my former colleagues there who will be out on the picket lines tomorrow and on subsequent days. There will be further escalation of strike action next week, with three days of strikes.

This industrial action arises from a dispute over pensions, pay, and working conditions. The strikes will affect 2.5 million students but are necessary to safeguard not only the livelihoods of academic staff against increased casualisation and salary cuts but the UK university system itself, which is being ruined by incompetent management. Regrettably, the strikes will cause considerable disruption but, frankly, there is no point in a strike that doesn’t do that.

Reflections on the St Brigid’s Day Holiday

Posted in Biographical, Education, Maynooth with tags , , on February 6, 2023 by telescoper

It’s Monday 6th February 2023, which means that today is a new experience for me: a Bank Holiday in February. This is taking place on the first Monday after Imbolc, a Gaelic festival marking the point halfway between the winter solstice and vernal equinox. The 1st day of February is also the Feast day of St Brigid of Kildare (c. 451-525), one of Ireland’s patron saints, along with Saints Patrick and Colm Cille. . From what I’ve read, St Brigid is an a sort of amalgamation of a pagan deity and an early Christian figure, part legend and part real person. One of her miraculous powers was the ability to change water into ale, which perhaps explains her enduring popularity among the Irish.

Anyway, it’s nice to have a day off even if it is just a week after the start of Semester Two, well before exhaustion sets in. Last week I started both my modules. I was particularly apprehensive about the first laboratory session for Computational Physics 1 on Thursday. In previous years the first session has always generated a lot of technical problems. This year we are running a new version of the operating system on our Linux cluster as well as a new version of Python. Students are issued with accounts specifically for use on this cluster and even logging for the first time and changing passwords has proved a challenge. I am now also using a digital display screen instead of the old data projector I used to have and which conked out last year.

This time, however, there were no significant problems at all in the Lab. Let’s hope the same is true for the Tuesday lab, which is a repeat but with a different (and slightly larger) group of students. In recognition of the likelihood of technical hitches I don’t usually aim to do very much in Lab 1, but this time I managed to cover quite a lot of material. By next week I’ll be starting to get the students to write bits of their own code. Thereafter it gets increasingly hands-on. There’s no efficient way to learn coding other than by doing it, so the sooner they get going with that the better.

I don’t actually have any lectures timetabled on Mondays this semester and, since the lab for tomorrow (Tuesday) is a repeat of last Thursday’s, I don’t have anything urgent to prepare. I’m therefore using the time off to do some Open Journal business – including publishing a paper – and, despite the cold, do a bit of gardening to prepare for Spring.

Solidarity with the UCU Strikers!

Tomorrow, 1st February 2023, members of the University and College Union will walk out for the first of 18 days of strike action in UK universities:

This industrial action arises from a dispute over pensions, pay, and working conditions. The strikes will affect 2.5 million students but are necessary to safeguard not only the livelihoods of academic staff against increased casualisation and salary cuts but the UK university system itself, which is being ruined by incompetent management. Regrettably, the strikes will cause considerable disruption but, frankly, there is no point in a strike that doesn’t do that.

Although I no longer work in the UK I’d like to take this opportunity to send a message of support to my former colleagues there who will be out on the picket lines tomorrow and on subsequent days.

That also goes for workers in other sectors who are also involved in industrial action in the UK at this time!

The Term Ahead

Posted in Biographical, Education, Maynooth with tags , , , , on January 29, 2023 by telescoper

It’s the day before the start of a new Semester in Maynooth. Last week we finished all due processes relating to the First Semester examinations and the provisional results will be uploaded to “The System” next week. They’re provisional at this stage because they’re not set in stone until the final meeting of the Examination Board. Obviously I can’t discuss the results here. I could comment here about how clunky the whole process is, including multiple downloads of spreadsheets and subsequent uploads somewhere else, but I won’t bother. Nobody seems to be interesting in fixing it. Perhaps by the time I retire “The System” will have been replaced by something that doesn’t waste an enormous amount of staff time. But I doubt it.

It’s a curiosity of the teaching allocation in the Department of Theoretical Physics that I do first-year and second-year modules (MP110 Mechanics and Special Relativity and MP201 Vector Calculus & Fourier Series) in Semester 1 while in Semester 2 it’s the third and fourth year students who have to put up with my ramblings.

The menu for this term involves MP354 Computational Physics 1, which entails just one hour of lectures per week but two two-hour lab sessions. Each student attends one of these sessions, so they get 3 contact hours per week but I have to look after both sessions. Our computer lab has a small cluster of Linux machines and, this term, a brand new display screen which I am looking forward to playing with. I’m also looking forward to seeing how the infamous ChatGPT copes with the Python coding exercises I give the students to do in class: I’ve only tried one so far, without much success. This is the first module I taught at Maynooth, back in 2018, so this will be the 6th time I’ve done it.

My other class is MP465 Advanced Electromagnetism, which I’m doing for the 3rd time now. This is a standard chalk-and-talk kind of module covering a well-established syllabus, and involving two lectures per week plus a tutorial. At least I’m teaching in a classroom rather than online like when I first did this module!

In 2020/21 (during the Pandemic restrictions) I did five modules as well as being Head of Department. At this time two academic staff departures left us severely short-staffed and struggling to deliver our programmes. My workload then was unmanageable and I asked to step down. I changed my mind when were eventually allowed to recruit two lecturers and saw out my three-year term to the end. I had better not repeat here what I think of the deliberate management decisions that left us reeling and had such negative effects on staff morale and on the education of students in the Department. I just hope the damage is not irreparable.

Although I am doing the same number of modules as last term, the number of contact hours I have to do is higher (8 versus 5) because of the labs and the fact that we don’t have tutors for 4th-year modules so lecturers have to do the tutorials themselves. Four modules a year is a much heavier teaching load than a Full Professor at a UK university would be expected to carry, but it seems normal in Ireland where the funding for sciences is far less than adequate. The impact on research productivity is obvious and is systemic. There are excellent physicists in Maynooth but they are given little time or other resources. It’s a big waste of potential. That’s another “System” that needs changing, but I see little appetite for change of the required sort at institutional level. It’s all about recruiting more and more students to be taught with fewer and fewer resources.

The impact of this on staff careers is severe: teaching loads are so heavy that it’s very difficult to reach the level of research productivity required for promotion. For myself, though, the next career step will be retirement so I don’t have to worry about promotion. Fortunately too, I enjoy teaching, so I’ll just get on with it. So I’ll stop writing and get on with preparing my first week of lectures and lab sessions!
