Challenges Past and Future

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

Yesterday afternoon we held our Departmental Examination Board in Theoretical Physics (via Microsoft Teams*) which all went remarkably well in the circumstances.

The most challenging thing to happen yesterday afternoon was that a bloke came to cut back the bushes outside my office with a very large and noisy hedge trimmer. I thought I was going to have to contend with that all afternoon but it seems he had done most of it the day before and only came back yesterday to finish off. He left before the Exam Board started.

The next stage of our Exams process is for all the Departmental results to be collated for those students on joint programmes before the final University Board takes place about ten days from now. After that students will get their results.

That doesn’t quite finish examination matters for 2019/20 however because some students will need to take repeat examinations in August. These will be a week later than usual as a knock-on effect of the extra week we were given to mark and correct the May exams. We anticipate that at least some of the repeats will be the traditional `in person’ on campus style, but some may be online timed assessments like the ones we held in May. That depends a bit on how the Covid-19 pandemic pans out in Ireland over the next few weeks (and of course how many students actually take repeats, as social distancing generates a capacity issue for the examination halls).

At the moment we are optimistic because the number of new cases of Covid-19 is low and stable. That coulld change, of course, if the virus starts to spread again so we have to have contingency plans.

Even more uncertain is what will happen in September, although I have been very annoyed by some reports in the media that seem to have been actively trying to put students off coming to University next academic year on the grounds that there won’t be any lectures. We certainly plan to offer as much face-to-face teaching as possible and I think other third-level institutions in Ireland will do likewise. There will of course have to be a backup if there is another lockdown, which may mean switching back to remote teaching at relatively short notice, but at least we’ve done that once already so know much better now what works and what doesn’t. Nevertheless I would encourage all potential students not to believe everything they read in the media nor be deterred from attending university by rumours from sources who don’t know what they are talking about.

Earlier this week I was starting to think about how we might build the required flexibility into our teaching for next year and two main things struck me.

The first is that while we have more-or-less been forced into making various kinds of video material available to students, this is something that I feel we should have been doing already. I’ve long felt that the more types of teaching we incorporate and the wider range of learning materials we provide the better the chance that students find something that works for them. Even if we do have a full programme of lectures next year, it is my intention to continue to provide, e.g., recorded video explainers as well because they might augment the battery of resources available to the student.

Some time ago I had to make some policies about `reasonable adjustments’ for some disabled students learning physics. In the course of providing extra resources for this small group I suddenly thought that it would be far better, and far more inclusive, simply to make these resources available to everyone. Likewise, we’ve been forced to adjust to providing material remotely but we should be thinking about how to keep the best things about what we’ve done over the last few months and embedding them in the curriculum for the (hopefully Coronavirus-free) future and not regard them all as temporary special measures.

The other thing that struck me is in the same vein, but a little more speculative. Over the last many years I have noticed that students use printed textbooks less and less for learning. Part of that may be because we in a digital age and they prefer to use online resources. The switch to remote learning has however revealed that there are some students who are disadvantaged by not having a good internet connection. I just wonder whether this might lead to a resurgence in the use of textbooks. I’ll certainly be making a strong recommendation to the new first-year students in Theoretical Physics that they should get hold of the recommended text, which I have previously regarded as an optional extra.

*At one point I got muddled up between Teams and Zoom and called it Tombs. It was a grave error, but it can only be a matter of time before Microsoft Tombs actually arrives…

Fly through of the GAMA Galaxy Catalogue

Posted in The Universe and Stuff with tags , , , , , , , , on March 13, 2014 by telescoper

When I’m struggling to find time to do a proper blog post I’m always grateful that I work in cosmology because nearly every day there’s something interest to post. I’m indebted to Andy Lawrence for bring the following wonderful video to my attention. It comes from the Galaxy And Mass Assembly Survey (or GAMA Survey for short), a spectroscopic survey of around 300,000 galaxies in a region of the sky comprising about 300 square degrees;  the measured redshifts of the galaxies enable their three-dimensional positions to be plotted. The video shows the shape of the survey volume before showing what the distribution of galaxies in space looks like as you fly through. Note that the galaxy distances are to scale, but the image of each galaxy is magnified to make it easier to see; the real Universe is quite a lot emptier than this in that the separation between galaxies is larger relative to their size.
