Keeping one’s head above water..

Posted in Biographical, Education, Maynooth on September 26, 2024 by telescoper

I had two teaching sessions today, on two different modules, both of which I’m teaching for the first time, and also had to prepare the first assignments for both sets of students, so I thought it might be a difficult challenge, metaphorically speaking, to keep my head above water. What I hadn’t expected, however, was that the rain would be bucketing down all day, making it almost literally difficult to keep above water. Now that I’ve done what I planned to do at work I have to make my way home through the deluge. At least I remembered to bring a brolly…

Back to Teaching

Posted in Education, mathematics, Maynooth with tags , , on September 24, 2024 by telescoper

So, after an absence from teaching of over a year, this afternoon I returned to the lecture theatre to give a double session on the module EE206 Differential Equations and Transform Methods. I was a bit apprehensive about having a two-hour slot and it is fair to say that I felt a bit knackered after it, but `then I am getting on a bit. I did have time for a ten-minute break in the middle during which the students could relax and stretch their legs a little. Some of them even came back afterwards.

This module is meant for students on two courses, Electronic Engineering and Robotics and Intelligent Devices, so I will have to think of relevant examples. I’ve got the RLC circuit, of course, but I’ll have to more than that!

If you’re interested you can find an old summary of the module here to see what topics are covered.

The good news from my point of view is that I have a decent room to teach in – complete with chalk boards – and the students seemed pleasant and engaged. I always like to get some interaction going in my classes so it was good to find a reasonable number of people willing to offer answers to questions I asked and indeed willing to ask me questions or request clarification. Overall, I was quite pleased with how it went. You will have to ask the students to see if they agree. At any rate I did manage to get through everything I planned to cover. The class size is about 55, incidentally.

Anyway, today I just warmed up for the module with some revision of basic calculus. I had pessimistically imagined that the students would have forgotten what they did in the first year about this, but in fact quite a few of them remembered quite a lot. I have my second session with this group on Thursday, though that should be a bit easier as it is only one hour instead of two. I will start differential equations proper then.

My remaining teaching sessions this week are all in the Arts Building. I have been quite worried that the rooms I am supposed to use would not be ready in time, but I took a walk around yesterday morning and they are ready (although construction work is going on elsewhere in the block). I was thinking I might have to give these lectures via a remote connection from home as in the old days of the pandemic, but that fortunately is not the case.

Autumnal Equinox 2024

Posted in Biographical, Education, Maynooth, The Universe and Stuff with tags on September 22, 2024 by telescoper

The Autumnal Equinox (in the Northern hemisphere) takes place this afternoon (Sunday 22nd September 2024)  at 13.44 Irish Summer Time (12.44 UT).

Although  the term `equinox’  refers to a situation in which day and night are of equal length, which implies that it’s a day rather than a specific time, the astronomical equinox is more accurately defined by a specific event, i.e. when the plane defined by Earth’s equator passes through the centre of the Sun’s disk (or, if you prefer, when the centre of the Sun passes through the plane defined by Earth’s equator). Day and night are not necessarily exactly equal on the equinox, but they’re the closest they get. From now on days in the Northern hemisphere will be shorter than nights and they’ll get shorter still until the Winter Solstice on 21st December 2024 at 9.21am Irish Time.

Many people take the autumnal equinox to be the end of summer. There is a saying around these parts, however, that `Summer is Summer to Michaelmas Day’ (September 29th), which is not until next week. I must say, though, though it doesn’t feel particularly summery this morning although we did have good weather for most of last week. Looking back over my posts on past occurrences of the Autumnal Equinox, it is notable how many talk about a period of good weather around this time of year. The Welsh phrase Haf Bach Mihangel (Michael’s Little Summer) refers to this kind of spell.

I’ve often remarked how the academic year at Maynooth is largely defined by the astronomical phenomena of the equinoxes and solstices. This year demonstrates this perfectly: Semester 1 lectures for undergraduates begin tomorrow (23rd September), the day after the Autumnal equinox; they end on 20th December, the day before the Winter Solstice. The half-term study break coincides with Samhain, a cross-quarter day. It’s all refreshingly pagan.

This time last year I was getting ready to travel to Barcelona. My sabbatical started on 1st September but I didn’t actually leave for Spain until 24th September. That all seems a very long time ago now, and my sabbatical is well and truly over. I resume teaching next week, though my first lectures (a double session of Engineering Mathematics) are not until Tuesday. I hope I can remember how to teach! I’m also doing Differential Equations and Complex Analysis for 4th Year Mathematical Physics students, but the lectures for that are a bit later (Thursday and Friday). I have taught neither of these modules before, so I am a bit apprehensive.

I now know what I’ll be teaching next Semester too. I’m returning to Computational Physics 1, which I taught for 5 years before my sabbatical, so that’s a familiar one. I’m also doing Particle Physics for 4th year students. I taught a full module in that at Nottingham and a half-module in Cardiff so it’s not exactly new but I haven’t lectured in the subject since about 2010. Has anything important happened in that field since then? I assume that had there been, for example, any new boson discovered I would have heard about it…

A New Term

Posted in Biographical, Education, Maynooth with tags on September 8, 2024 by telescoper

WARNING: THIS BLOG IS BANNED ON MAYNOOTH UNIVERSITY CAMPUS

I’m well and truly back from sabbatical: I spent most of Friday filling in forms.

It is now just two weeks before teaching resumes after the summer break. To add even more excitement to this, the building housing the rooms in which half of my scheduled lectures (and many of those of my colleagues) are to take place is still a construction site. The work was supposed to be completed by September 1st. Will the rooms be ready by September 23rd? I have no idea. What will we do if they’re not? I have no idea. We’ll just have to wait and see.

I still have the blackboard in my study that I used to give remote lectures during pandemic times. I wonder if I’ll be using it again? I thought this time round we would have a relatively smooth introduction to term, as opposed to the mad scramble caused in previous years by delayed Leaving Certificate results, but…

Among the new arrivals will be a cohort of students on our MSc in Theoretical Physics and Mathematics. I understand we have approximately 9 students which is not a bad start for a new postgraduate course. That means we’ll have to think up some projects for them to do. I might do that this afternoon, in fact.

Anyway, this coming week we have the first Departmental Meeting of the (new) Department of Physics. Hopefully we might find out how the merger is actually meant to work in practice. The day after that we meet the new (Interim) Dean of the Faculty of Science & Engineering. Incidentally the President of Maynooth University made this appointment in a way that is in direct conflict with the Statutes of the University. That’s par for the course at Maynooth these days, I’m afraid, as is the censorship of this blog.

This time next week we’ll be looking ahead to Welcome Week when the new students arrive and have a chance to look around and choose their modules. The local Facebook page is alive with messages from desperate students and their parents looking for accommodation in or near Maynooth. The University likes to boast about how many more students it will have this year, but not a thought is given to where they will live. The strain of having to travel long distances to campus, combined with the high cost of living necessitating many students to take on more-or-less full time employment, looks likely to ensure that drop-out rates climb still further.

Congratulations to the Class of 24!

Posted in Education, Maynooth with tags , , on September 6, 2024 by telescoper

After almost a whole week of conferring ceremonies at Maynooth University, today was the day that this year’s Theoretical Physics students graduated. We all know that theoretical physicists are la crème de la crème so they were obviously keeping the best until last. Anyway, congratulations all!

Here’s a suitable image from Private Eye years ago:

Induction and Conferring

Posted in Biographical, Education, Maynooth with tags , , , , on September 4, 2024 by telescoper

I was away yesterday dealing with some personal matters and on the way home I was so bored that I took a rare glance at my LinkedIn feed and found this, which unfortunately refuses to be embedded properly.

https://www.linkedin.com/posts/royal-grammar-school-newcastle_wearergs-activity-7236768897327087616-8Iz8

Anyway, it reminded me that it was 50 years ago this week that I went through a similar induction process at the Royal Grammar School Newcastle and was about to begin my Secondary Education along with my classmates in 1E, one of whom I wrote about here. We didn’t have “Year 3”, “Year 7” and “Year 11” in those days; we were just called “First Years”, which I guess is Year 7 in today’s currency. The Hall hasn’t changed much since my day. Although it looked enormous then, to a little boy, to an adult it looks very small to accommodate over a thousand pupils. At the morning School Assemblies many of us had to stand around the edges.

Meanwhile, back in the present week, Maynooth University is hosting events at which degrees are conferred. The cohort of undergraduate students graduating at this week’s ceremonies are those that took their final examinations in May/June this year (while I was away on sabbatical) so I didn’t teach any of them this year. I will, however, be seeing some again as they return for postgraduate degrees.

In a couple of weeks we will be having induction events for the new intake of students at Maynooth University. Most of our students are on 4-year programmes, so it well be September 2028 that the latest crop have their conferring ceremonies. If all goes to plan I shall have retired by then.

A New Department of Physics

Posted in Biographical, Education, Maynooth with tags , , , on September 2, 2024 by telescoper

My first official day back at work after a year-long sabbatical coincides with the first official day of a new Department of Physics at Maynooth University:

I knew this was happening, of course, and it should have happened years ago. Having two separate Physics Departments at Maynooth was not just an oddity. It required the relatively small number of academic staff across the Departments to undertake a huge amount of duplication in teaching thereby wasting resources and increasing workloads. Even combined together, the total complement of 15 academic staff means that we’re still a very small Department.

There are, therefore, potential benefits in this merger but they will take time to accrue. At the moment it only exists on paper, and staff in the two ex-Departments will have to work out what to do next in terms of coordinating teaching and research. In my opinion this all should have been planned and agreed before going ahead, but here we are. We just have to make the best of the situation presented to us by The Management.

For the time being the New Department is just the two Old Departments in a single wrapper. We were already located side-by-side in the same building, the Science Building so there are no large-scale relocations of staff, at least not yet. All existing courses remain the same as before, too. That’s just as well, really, as we start teaching in three weeks!

That’s not to say that nothing has changed. The number of postgraduate and postdoctoral researchers in the Department of Theoretical Physics has been growing and there was consequently a drastic shortage of office space. My return from sabbatical has involved me being granted an elevated status in the new Department: I’ve been moved upstairs out of the old Theoretical Physics Department to an office in the old Experimental Physics Department.

Here’s a question, though. My contract of employment says that I am employed in the Department of Theoretical Physics. Since that Department no longer exists, do I need a new contract or have I been made redundant?

P.S. I wrote this blog at home before going to the office as this blog remains banned on Maynooth University campus.

A Time to Offer

Posted in Education, Maynooth with tags , , , , , , on August 28, 2024 by telescoper

Today is the day that students across Ireland receive offers of places at Third-Level Institutions to start next month; the full set of CAO points required for different courses in different institutions are available in searchable form here and in a more user-friendly interface here. I have been away on sabbatical for a year so have been out of the loop for admissions. In past years I got an idea of how things were going from Open Days, etc, but not this time round.

This is of course just the first round of offers so things may change significantly over the next week or two. Students now have to decide whether to accept their first-round offer or try to change course. They have until next Tuesday to do this. Departments won’t know how many new students they have for a while yet.

The official low-tech results for Maynooth (in the lower right of the page shown above) are here. Minimum points required for Maynooth’s – and indeed Ireland’s – most important course, MH206 Theoretical Physics and Mathematics, are 513 this year, up a from 493 last year. Here’s a graph of how the CAO points for this course have varied over the years since 2010:

The entry level has been rather steady but note that Leaving Certificate grades have been adjusted upwards for the past few years so 500 points in 2024 is not equivalent to the same number in (say) 2016. The above graph doesn’t show how many students were recruited each year either.

MH201 General Science is 350 this year (same as last year); MH204 Physics with Astrophysics is 383 this year, up slightly from 376 last year. MH101 General Arts – the most popular course at Maynooth and indeed in all Ireland – has a first round offer of 307 this year, down from 310 last year. Most courses I have looked at in Maynooth have first-round offers this year similar to or lower than last year. Across all institutions, required points have fallen or remained unchanged for about 57% of courses.

This is interesting because it contrasts with news stories about grade inflation on the Leaving Certificate; I blogged about this here. It is perhaps worth pointing out that the CAO points needed for a course is largely a matter of demand versus capacity rather than academic performance. For the last few years Maynooth University has been recruiting more and more students, putting pressure on accommodation, teaching loads and campus space. It seems likely that the desire to keep this trend going is at least part of the reason for the continued falls in CAO points here. This is probably happening to some extent across the sector, though Maynooth has a more urgent need for more students: to pay for the legions of new managers it has appointed. The race to the bottom will really accelerate when the Covid-era Leaving Certificate adjustment is removed.

Update: here is the traditional supplement from Thursday’s Irish Times:

Leaving Certificate Results

Posted in Bad Statistics, Covid-19, Education, Maynooth with tags , , , , , , on August 23, 2024 by telescoper

Today’s the day that over 60,000 school students across Ireland are receiving their Leaving Certificate Results. As always there will be joy for some, and disappointment for others. The headline news relating to these results is that a majority (68%) of grades have been scaled up to that the distribution matches last year’s outcomes. This has meant an uplift of marks by about 7.5% on average, with the biggest changes happening at the lower levels of grade.

This artificial boost is a consequence of the generous adjustments made during the pandemic and apparent wish by the Education Minister, Norma Foley, to ensure that this year’s students are treated “fairly” compared to last year’s. Of course this argument could be made for continuing to inflate grades next year too, and the year after that. Perhaps the Minister’s plan seems to be to keep the grades high until after the next General Election, after which it will be someone else’s job to treat students “unfairly”. Anyway, you might say that marks have been scaled to maintain a Norma Distribution…

One can’t blame the students, of course, but one of the effects of this scaling is that students will be coming into third-level education with grades that imply a greater level of achievement than they actually have reached. This is a particular problem with a subject like physics where we really need students to be comfortable with certain aspects of mathematics before they start their course. It has been clear that even students with very good grades at Higher level have considerable gaps in their knowledge. This looks set to continue, and we will just have to deal with it. This issue was compounded for a while because Leaving Certificate grades were produced so late that first-year students had to start university a week late, giving less time for the remedial teaching that many of them needed. At least this year we won’t have that problem, so can plan some activities early on in the new Semester.

Anyway, out of interest – probably mine rather than yours – I delved into the statistics of Leaving Certificate results going back six years for Mathematics (at Higher A and Ordinary B) level, Physics and Applied Mathematics which I fished out of the general numbers given here.

Here are the results in a table, with the columns denoting the grade (1=high) and the numbers are percentages:

You can seen that the percentage of students getting H1 in Mathematics has increased a bit to 12.6% after falling considerably from 18.1% in 2022 to 11.2% last year (2023); note the huge increase in H1 from 2020 to 2021 (8.6% to 15.1%). Another thing worth noting is that both Physics and Applied Mathematics have declined significantly in popularity since 2019 from 7210.

Now that the results are out there will be a busy time until next Wednesday (28th) when the CAO first round offers go out. That is when those students wanting to go to university find out if they made the grades and university departments find out how many new students (if any) they will have to teach in September.

P.S. When I was a little kid we used to call a “Certificate” a “Stiff Ticket”. I just thought you would like to know that.

Back to A-level Again

Posted in Cardiff, Covid-19, Education with tags , , , on August 16, 2024 by telescoper

Yesterday was the day that students in United Kingdom received this year’s A-level results. It seems the number of students getting the highest grades went up in England but down in Wales and Northern Ireland. That difference could be because of the timing of the transition from Covid-19 adjustments, with marks in Wales and Northern Ireland only returning to pre-pandemic levels this year; this may disadvantage applicants to universities this year, of course.

Another thing worth mentioning is that the number of students taking Physics A-level has increased by 12% this year, reversing a recent downward trend. In Physics, 31.5 per cent of students achieved the top grades. This was an increase from last year when 30.8 per cent were awarded an A or A*. That probably means that most students who applied to do Physics at university will get a place in their first-choice institution.

As always my advice to students who got disappointing results is

There’s always the clearing system and there’s every chance you can find a place somewhere good. If you’re reading this blog you might be interested in Physics and/or Astronomy so I’ll just mention that both Cardiff and Sussex have places in clearing and both are excellent choices.

At least you’ve got your results; students here in Ireland will have to wait next Friday (23rd August) to get to get theirs – not in the form of GCE A-levels, of course, but the School Leaving Certificate. I have been away all year so don’t know how admissions have been going for Maynooth but the intention seems to be to increase student numbers in any way possible despite the already huge student-staff ratio (the highest in Ireland) and lack of student accommodation. Anyway, Covid-19 adjustments are still in place in Ireland so the artificial inflation of Leaving Certificate grades will continue. It seems the Government doesn’t know how to get out of the system it has locked itself into and is intent on leaving it for the next Government to sort out.
