Examinations, Past and Future

Posted in Biographical, Education, mathematics, Maynooth with tags , , , , , on June 7, 2023 by telescoper

No sooner is yesterday’s departmental Examination Board done and dusted (after just two and a half hours) when attention switches to school examinations. The Junior Certificate and Leaving Certificate examinations both start today, so the first thing I need to do is wish everyone taking examinations the very best of luck!

Among other things, the results of the leaving certificate examinations are important for next year’s University admissions. As we gradually dispense with the restrictions imposed during the pandemic, it seems this year we just might have the results before the start of teaching at the end of September. That will make a nice change!

In the system operating in England and Wales the standard qualification for entry is the GCE A-level. Most students take A-levels in three subjects, which gives them a relatively narrow focus although the range of subjects to choose from is rather large. In Ireland the standard qualification is the Leaving Certificate, which comprises a minimum of six subjects, giving students a broader range of knowledge at the sacrifice (perhaps) of a certain amount of depth; it has been decreed for entry into this system that an Irish Leaving Certificate subject counts as about 2/3 of an A-level subject for admissions purposes, so Irish students do the equivalent of at least four A-levels, and many do more than this. It’s also worth noting that all students have to take Mathematics at Leaving Certificate level.

Overall I prefer the Leaving Certificate over the UK system of A-levels, as the former gives the students a broader range of subjects than the latter (as does the International Baccalaureate). I would have liked to have been allowed to take at least one arts subject past O-level, for example.

For University admissions points are awarded for each paper according to the marks obtained and then aggregated into a total CAO points, CAO being the Central Applications Office, the equivalent of the UK’s UCAS. This means, for example, that our main Science pathway at Maynooth allows students to study Physics without having done it at Leaving Certificate level. This obviously means that the first year has to be taught at a fairly elementary level, but it has the enormous benefit of allowing us to recruit students whose schools do not offer Physics.

As much as I like the Leaving Certificate, I have concerns about using a simple CAO points count for determining entry into third-level courses. My main concern about is with Mathematics. Since the pandemic struck, students have been able to choose to questions from just six out of ten sections. That means that students can get very high grades despite knowing nothing about 40% of the syllabus. That matters most for subjects that require students to have certain skills and knowledge for entry into University, such as Physics.

I’ve been teaching the first year Mathematical Physics course in Maynooth for about 5 years. At the start of the module I put up a questionnaire asking the students about various mathematical concepts and asking them how comfortable they feel with them. It’s been noticeable how the fraction that are comfortable with basic differentiation and integration has been falling. That’s not a reflection on the ability of the students, just on the way they have been taught. As well as making adjustments during the pandemic for online teaching, etc, I have changed various things about the teaching, in particular adjusting the way I have introduced calculus into the module. Another problem is that we have been forced to start teaching first-years a week late because of delays to the CAO process caused by the pandemic.

I’ll be on sabbatical next academic year so I won’t be teaching the first-years (or anyone else) in September. It’s time to hand these challenges on to someone else!

Terms Ending

Posted in Biographical, Education, Maynooth with tags , , , on May 26, 2023 by telescoper

So here I am, on a fine early summer evening, waiting for the train into Dublin for the last performance of the season by the National Symphony Orchestra at the National Concert Hall. I’m looking forward to it very much, as the second half is a piece I’ve never heard before. I’ll write more about it tomorrow.

There’s an end of term feeling in other ways, too. The examination period ended earlier this week, and most students have now vanished for the summer. Quite a few staff members will be marking scripts at home too. Campus has been very quiet for the last few days. The train I’m now on, the 17.10 from Maynooth to Connolly, usually very busy on a Friday, is almost empty today.

The one exception to the general lack of activity on campus happened on Wednesday when a mysterious ferret appeared on Campus. It even tried to get into the Science Building, but failed (I suppose) because it didn’t have a swipe card. It seems this critter was a family pet that had got out and went on an adventure. It was spotted at various locations around the town before being collected by its owner and returned safely home.

Artist’s impression of the ferret.

Despite that flurry of excitement, I managed to finish marking my examinations and other assessments, but the grades still need to be checked. They then have to be approved by the Departmental Exam Board in early June. They then get a final dose of scrutiny at the University Examination Board. Students will have to wait almost another month to get their results. It’s quite a slow process, but it’s right to be careful.

MSc in Theoretical Physics & Mathematics at Maynooth

Posted in Education, Maynooth, The Universe and Stuff with tags , , on May 25, 2023 by telescoper

Now that the exams are over I thought I’d take the opportunity to promote our new MSc in Theoretical Physics & Mathematics. The existence of this was only announced in April and it was fully opened to applications just a couple of weeks ago. The University’s social media people have been pushing it very hard recently with, so I’m told, some success! Here are a few examples of the images that have been used in the ads:

Anyway, this (new) postgraduate course will be run jointly between the Departments of Theoretical Physics and Mathematics & Statistics, with each contributing about half the material. The duration is one calendar year (full-time) or two years (part-time) and consists of 90 credits in the European Credit Transfer System (ECTS). This will be split into 60 credits of taught material (split roughly 50-50 between Theoretical Physics and Mathematics) and a research project of 30 credits, supervised by a member of staff in a relevant area from either Department.

This new course is a kind of follow-up to the existing undergraduate BSc Theoretical Physics & Mathematics at Maynooth, also run jointly. We think the postgraduate course will appeal to many of the students on that programme who wish to continue their education to postgraduate level, though applications are very welcome from suitably qualified candidates who did their first degree elsewhere.

Postgraduate admissions in Ireland operate differently from the UK, in that there is a central system in Ireland (called PAC) that is similar to the undergraduate admissions system; in the UK PG courses are dealt with by individual institutions. You will need to apply online via PAC after the following the instructions here. The requisite PAC code for the full-time version of the course is MHQ56.

If you apply by 30th June you may be eligible for one of the University’s Taught Masters Scholarships!

After the Lectures, before the Examinations

Posted in Education, Maynooth, The Universe and Stuff with tags , , on May 11, 2023 by telescoper

This morning I did my last teaching session of the Academic Year 2022-3, a revision lecture/tutorial on Computational Physics. It was optional, as this is officially a study break, and was at 9am, but I had about 40% attendance which wasn’t bad in the circumstances. As is often the case with optional sessions, I think the students who came were the keenest and probably therefore those who least needed last-minute tips for the examination, but that’s always the way.

The Examination Period starts tomorrow, but most of the students who turned up this morning have their first examination on Monday. My paper is on Saturday next, 20th May.

Anyway, now that my teaching is over I thought I’d take the opportunity to wish all students the best for their examinations:

You shouldn’t really be relying on luck of course, so here are some tips (especially for physics students, but applicable elsewhere).

  1. Try to get a good night’s sleep before the examination and arrive in plenty of time before the start. Spending all night cramming is unlikely to help you do well.
  2. Prepare well in advance so you’re relaxed when the time comes.
  3. Read the entire paper before starting to answer any questions. In particular, make sure you are aware of any supplementary information, formulae, etc, given in the rubric or at the end.
  4. Start off by tackling the question you are most confident about answering, even if it’s not Question 1. This will help settle any nerves. You’re under no obligation to answer the questions in the order they are asked.
  5. Don’t rush! Students often lose marks by making careless errors. In particular, check all your numerical results on your calculator at least twice
  6. Please remember the units!
  7. Don’t panic! You’re not expected to answer everything perfectly. A first-class mark is anything over 70%, so don’t worry if there are bits you can’t do. If you get stuck on a part of a question, don’t waste too much time on it (especially if it’s just a few marks). Just leave it and move on. You can always come back to it later.

A Midweek Lecture

Posted in Biographical, Education with tags , , , , on May 3, 2023 by telescoper

It’s halfway through the last week of teaching term, and it’s been a busy day. Earlier on, I gave my final “proper” lecture of the Semester in Advanced Electromagnetism, about the reflection and transmission of electromagnetic waves at interfaces. That’s basically optics, but done in terms of the electric and magnetic fields. I have two more classes this week, on Friday, but these will be revision tutorials devoted to going through past examination questions etc. I’ve had special requests for problems involving conformal transformations and the method of images, so that should be fun!

Meanwhile, my Computational Physics class are working hard on their projects, due in on Friday. My office is opposite the lab so I’ve had a few students coming to ask for help, but mostly they are just beavering away. I hope most of them are writing up by now. I just did a quick check and nobody has submitted anything yet. I suppose that, as usual, they will all wait until the last minute!

I have a telecon coming up in a few minutes, but after that I’ll be attending this public lecture:

The speaker, Professor Clare Elwell is a physicist at University College London, where she is the Director of the Near Infrared Spectroscopy (NIRS) Group. Specifically, Prof Elwell develops non-invasive techniques to study brain function, paving the way for defining early markers of autism, developing more targeted care following brain injury, and for better understanding brain development in global health settings. Prof Elwell described her pioneering work in using invisible near infrared light to probe the human brain. Near Infrared Spectroscopy (NIRS) is a portable, wearable, low-cost brain imaging technology which can be used to study the brain in newborn babies, toddlers and adults in a range of different scenarios.

I’ll post an update when I get home after the lecture. Actually, there’s no need because the lecture was streamed and a recording is now available. The lecture starts a fairly long way in and the sound didn’t start until part-way through the introductions so I’ve cued the link to the start of the lecture itself.

It was a very interesting lecture by a very engaging speaker. The audience was smaller than I’d expected, though, with less than a hundred in the theatre. This might be because it was scheduled in the middle of the last week of teaching term, which is a very busy time of year for academic staff.

No Tension at Redshift Ten

Posted in Maynooth, The Universe and Stuff with tags , , , , , on April 29, 2023 by telescoper

I know it’s the Bank Holiday weekend but I could resist a quick post about a new paper that hit the arXiv yesterday (where all new astrophysics papers worth reading can be found). It is led by Joe McCaffrey who is a PhD student in the Department of Theoretical Physics at Maynooth University. The paper has been submitted to the Open Journal of Astrophysics, but obviously I am conflicted so have assigned it to another editor.

As many of you will be aware, there’s been a considerable to-do not to mention a hoo-hah about the detections by JWST of some galaxies at high redshift. Some of these have been shown not to be galaxies at high redshift after all, but some around z=10 seem to be genuine.

Anyway, the abstract of Joe’s paper is this:

Recent observations by JWST have uncovered galaxies in the very early universe via the JADES and CEERS surveys. These galaxies have been measured to have very high stellar masses with substantial star formation rates. There are concerns that these observations are in tension with the ΛCDM model of the universe, as the stellar masses of the galaxies are relatively high for their respective redshifts. Recent studies have compared the JWST observations with large-scale cosmological simulations. While they were successful in reproducing the galaxies seen in JADES and CEERS, the mass and spatial resolution of these simulations were insufficient to fully capture the early assembly history of the simulated galaxies. In this study, we use results from the Renaissance simulations, which are a suite of high resolution simulations designed to model galaxy formation in the early universe. We find that the most massive galaxies in Renaissance have stellar masses and star formation rates that are entirely consistent with the observations from the JADES and CEERS surveys. The exquisite resolution afforded by Renaissance allows us to model the build-up of early galaxies from stellar masses as low as 104 M⊙ up to a maximum stellar mass of a few times 107 M⊙. Within this galaxy formation paradigm, we find excellent agreement with JADES and CEERS. We find no tension between the ΛCDM model and current JWST measurements. As JWST continues to explore the high redshift universe, high resolution simulations, such as Renaissance, will continue to be crucial in understanding the formation history of early embryonic galaxies.

arXiv:2304.13755

The key figure is this one:

The solid curves show the number of galaxies of a given mass one would expect to see as a function of redshift in fields comparable to those observed with estimated values from observations (star-shaped symbols). As you can see the observed points are consistent with the predictions. There’s no tension, so you can all relax.

Maynooth Open Day Admissions

Posted in Education, Maynooth with tags , , on April 22, 2023 by telescoper
The Day Before The Open Day

Well, it’s Saturday 22nd April and it’s another Open Day at Maynooth University. I was there for the similar event at this time last year, and many others before that, but others are doing it this year so I’m sitting at home drinking coffee and writing this blog. I hope it’s going well (though it is raining quite heavily as I write this).

This year’s event is in the new TSI building on the North Campus, a change of venue since last year when it was in the Iontas building. I went in there last night on my way home to have a look at the setup. Our stand was pretty bare then but it will be a bit more exciting now (I hope).

In previous years I taught the first-year module in Mathematical Physics taken by new students, some of whom recognized me from an Open Day. I won’t be teaching the first-years this September, though. I won’t be teaching anyone else this September, either, as I’ll be away on sabbatical for the whole academic year.

The real problem facing first-years, however, is that it seems that yet again this year’s Leaving Certificate results will be late. Last year, new students started a week later than returning students, meaning their teaching term was truncated. The shift from August release to September was excusable during the Covid-19 pandemic, but its continuation is a farcical and is causing huge stress for new students, arising from difficulties in finding accommodation and no time for proper induction events on top of the delayed start to lectures. Well have to wait until June to see how much all this has affected progression rates.

There was an opinion piece about this in the Irish Times last week, from an academic at Trinity, which I agree with and I think is well worth reading. Here’s a quote:

This may all have once felt like an inevitable consequence of the pandemic, but the novelty has long since worn off. Students and universities alike have been left frustrated and hugely discommoded.

The word “discommoded” is a considerable understatement. Let’s just hope that the start of next year is less chaotic than the last three. The academic year at Maynooth starts and ends a bit later than other Irish third-level institutions, so our students have only lost a week at the beginning. Elsewhere more time has been lost: two weeks at Trinity, for example. I wonder if this particular selling-point will be mentioned to prospective students at the Open Day?

Teaching those who want to learn

Posted in Biographical, Education, mathematics, Maynooth with tags , , , on April 21, 2023 by telescoper

Yesterday afternoon I ran the last formal Computational Physics laboratory of the term. As is often the case with these sessions, the students were given a Python task to work through, with assistance available from myself and a demonstrator (and indeed other students). We have 25 students registered on this module, who are split into two groups, so about a dozen students were in yesterday’s session. That’s a comfortable number to make sure everyone can get some help.

This is the sixth year I’ve done this module, and I decided a long time ago that the best way to ensure that students learn the necessary skills is to give them things to do and let them work things out for themselves (with help where necessary). A couple of years ago, on my module feedback questionnaire, a student wrote an intended criticism along the lines of – “It’s like he expects us to learn to code by doing it ourselves, rather than him teaching us”. That is, of course, exactly what I intended, though we do give plenty of help during the labs.

Just as the best way to learn a foreign language is by speaking it, the best way to learn coding is by writing programs. Some of the students on this module have done any before, so for them the early stages of the module are rather straightforward. At least half the class, however, haven’t done any programming, so for them it’s a fairly steep learning curve.

Anyway, it being the last formal session of term this week’s task was a rather challenging one, involving the solution of a boundary value problem via the shooting method. It’s a good exercise because it brings together methods for solving ordinary differential equations with root-finding, as well as requiring some thought as to the general construction of a code that combines these two.

As expected, given the difference in background of the students, some finished this in good time, but others went more slowly. Some very excellent things happened, though, which made me very happy with the the whole experience.

One was that instead of leaving as soon as they had finished, a few of the students who had completed the task early stayed behind to help their friends. I encourage this, but it doesn’t always happen as much as yesterday. It’s called teamwork, and it’s essential not only in physics but also in everyday life.

The lab session was supposed to finish at 4pm, but not all students were done by then. Another excellent thing though was they didn’t just quit when they had run out of time. I stayed well past 4pm to help those who were determined to finish. In one case it was just a ‘0’ that should have been a ‘1’ in the index of an array that stopped it working. I don’t know why it took me so long to spot this, but we got there in the end.

One student, however, had another class at 4pm so left, only to return at five to continue. The student finally left, having completed the exercise, at about 6.45. The persistence shown by the students in refusing to be defeated was truly admirable. This harks back to a piece of advice I gave some time ago:

If you really want to develop as a physicist, don’t just solve a lot of easy problems; challenge yourself by tackling difficult ones too. Don’t be afraid to get “stuck” or make a mistake, as those are both necessary parts of the learning process. Above all, develop the confidence in your ability to take on a problem and back yourself to solve it and don’t be deterred if the answer doesn’t come quickly!

You may say that if it took some students much longer than the allocated time to finish then the problem was too difficult. That may be the case, but do you ever really learn if you’re not stretched? There is a place for straightforward formulaic tasks in higher education, but there’s much more to a university education than doing things like that.

Obviously the lab took up much more of my time as I had originally planned – more than double, in fact – but I went home pleased with a good day’s work. As I’ve said on this blog many times before, there are few things more rewarding than teaching students who want to learn.

Student Feedback and Lecture Recordings

Posted in Cardiff, Education, Maynooth with tags , , on April 19, 2023 by telescoper

This afternoon we had a very interesting meeting about teaching in the Department of Theoretical Physics at Maynooth University, involving teaching faculty and student representatives from each year of each of the courses we offer.

It was nice that most of the feedback gathered by the student reps from their peer groups was positive. For one thing, they really like the blackboard-based teaching we use to deliver most of our modules. Most of the negative comments, however, related directly to lack of resources.

A particular concern, expressed unanimously by all the student reps at the meeting, was the lack of lecture recordings. I don’t think I am alone among the teaching staff in the Department in saying that I wish we could offer lecture recordings as routine. Unfortunately, however, and much to my disappointment, the Senior Management at Maynooth University has discouraged lecture recording as a matter of policy and has not invested in the technology required to make this possible so it is not practicable anyway.

My two previous employers – the University of Sussex and Cardiff University – both had systems in place long before the Covid-19 pandemic and all lectures were recorded as standard . I blogged about this 8 years ago, in fact. In my view the benefits of lecture capture far outweigh the disadvantages, and we should incorporate recordings of lectures as part of our standard teaching provision, as a supplement to learning rather than to replace face-to-face sessions. Every student learns in a different way and we should therefore be doing as much as we possibly can to provide a diverse range of teaching resources so that each can find the combination that suits them best. Technology allows us to do this far better now than in the past.

Some really enjoy live in-person lecture sessions, especially the ability to interact with the lecturer and the shared experience with other students, but others don’t like them as much. Others have reasons (such as disability) for not being able to attend in-person lectures, so providing recordings can help them. Others still have difficulty attending all lectures because of a dratic shortage of student accommodation. Why not in any case provide recordings for everyone? That seems to me to be a more inclusive approach.

The problem with lecture capture in Maynooth is that we will need to improve the cameras and recording equipment in the large lecture rooms to make it possible for lectures with a significant mathematical content. The existing setups in teaching rooms do not easily allow the lecturer to record material on a whiteboard or blackboard. In Cardiff, for example, the larger rooms have more than one camera, usually one on the lectern and one on the screen or whiteboard (which has to be placed further away and therefore needs to be of higher resolution). In Maynooth we only have small podium cameras in the teaching rooms. In fact I have far better facilities in my study at home – provided at my own expense – than my employer is prepared to provide on campus.

My home teaching room

I’m baffled and frustrated by Maynooth’s decision in this matter, which is generating a great deal of negativity amongst faculty and students alike. I hope The Management can be persuaded to change its mind. Persisting with the current policy would send a clear message that teaching and learning are not valued at Maynooth. Maybe they just aren’t?

P.S. The single most common inquiry I have received about the new MSc course announced recently has been whether it is possible to take it remotely. Given our lack of recording facilities, regrettably the answer to this is “no”.
