In the Dark

This morning I came across a very interesting blogpost by Philip Moriarty which is mainly about teaching quantum mechanics but also includes some discussion of his ideas of how he plans to conduct teaching for the forthcoming semester at the University of Nottingham.

We are in a rather different situation here at Maynooth University with Covid-19 different rules, different numbers of students and different levels of resource in terms of teaching software and equipment, but I think the primary constraints are similar.

Here is is graphic Philip uses to outline the major elements of teaching he plans to adopt (copied without permission):

I think the University of Nottingham has, in common with many other UK universities, moved all its large lecture classes online. Here in Maynooth we’re restricted by physical distancing to have an absolutely maximum of 50 people in any lecture theatre at one time, so effectively the big classes will be online too. However, many of our smaller classes and tutorials will be on campus `face-to-face’ sessions. Since Theoretical Physics is a relatively small Department many of our modules will run pretty much as normal.

This are a bit different for the first year Mathematical Physics module which I teach (MP110) where the class last year was about 90 students. This class will have to be split, but I am still planning to deliver face-to-face lectures for all students in some form. There are three lectures a week in this class and I’ll probably have to have about one third of the students in each session: the other sessions will be streamed and recorded – assuming our newly-installed Panopto system works (!) – and made available to students not at the class. In addition students will get a tutorial per week, also in person.

I have thought a lot about this over the last few months and I’ve decided that the main `lectures’ (which will be with fewer than 30 students) will not be lectures but more like `workshops’ where I illustrate the main results that I would have given in a “normal” lecture using examples as well as getting students to work on problems in class.

Like Philip I plan to record videos of the “primary content” offline, probably in my office, so the students can view them at their leisure. I decided to record these primarily because I think the production quality of such lectures would be better. I’ve used Panopto before and it’s OK, but it has its limitations. I don’t have access to all the equipment Philip talks about, but at least in my office I can re-take and edit the video whenever I mess up (which will be quite frequently, I’m sure). These won’t be 50-minute lectures as I find that not having the interaction with the audience, going back over things when it’s clear they haven’t understood, giving them problems to try in class, etc, the time taken to cover the material in a video is far shorter.

Making these `asynchronous’ is, I think, extremely important. Timetabling teaching sessions looks likely to be extremely complicated for the forthcoming semester so I think it’s far better to make the content available for students to study wherever and whenever they want.

So my plan is that students will get each week:

• A set of pre-recorded videos covering the material for that week
• One interactive workshop on campus
• Access to recordings of two other workshops
• A full set of lecture notes
• Coursework examples (assessed)
• One tutorial on campus
• A virtual office hour with the lecturer (me) for Q&A

It’s not the same “as normal” but I think it provides the best blend of learning approaches possible under the constraints we will have to operate. Note also that some students may be “at very high risk” for health reasons and consequently unable to come onto campus. The approach I have outlined here means that such students will miss as little as possible.

Unlike Philip, I don’t hate Moodle, so this will be where all the course materials will be made available. It will also be the principal channel of communication with the class.

Like Philip, though, I am in favour of putting all the primary content on Youtube so that anyone who wants to access it can do so. I have suggested this before and it received mixed reactions, but for me it’s more a point of principle. As my teaching is funded by the public purse, it seems reasonable to me that what I produce should all be in the public domain wherever possible. That obviously excludes some teaching activities (e.g. labs and tutorials) but I don’t see why I shouldn’t do it with lectures or other video content. I won’t make the workshop videos public, because they may accidentally identify students who do not wish to appear on a video.

I know many of my colleagues disagree with this, so here’s the unscientific poll I’ve been running to see what people think. Not that the voting will change my mind….
