Learning Technology

I’m just taking a tea break in the Data Innovation Research Institute. Today has been a very day as I have to finish off a lot of things by tomorrow, for reasons that I’ll make clear in my next post…

It struck me when I was putting on the brew how much more technology we use for teaching now than when I was a student. I think many of my colleagues make far more effective use of the available technology than I do, but I do my best to overcome my Luddite tendencies. Reflecting on today’s teaching makes me feel just a little less like a dinosaur.

This morning I gave a two-hour lecture on my Cardiff module Physics of the Early Universe which, as usual, I recorded using our Panopto system. Although there was a problem with some of the University’s central file storage this morning, which made me a bit nervous about whether the lecture recording would work, it did. Predictably I couldn’t access the network drives from the PC in the lecture theatre, but I had anticipated that and took everything I needed on a memory stick.

After a short break for lunch I checked the lecture recording and made it available for registered students via the Virtual Learning Environment (VLE), known to its friends as Learning Central. I use this as a sort of repository of stuff connected with the module: notes, list of textbooks, problem sets, model answers, instructions and, of course, recorded lectures. The students also submit their coursework assignment (an essay) through this system, through the plagiarism detection software Turnitin.

This afternoon the students on my Computational Physics course in Maynooth University had a lab test, the first of four such tests, this one consisting of a short coding exercise. There are two lab sessions per week for this class, one on Thursdays (when I am normally in Maynooth to help supervise) and another on Tuesdays (when I am normally in Cardiff). I have a number of exercises, which are similar in scope but different in detail (to prevent copying) and the Tuesday lab has a completely different set of exercises from the Thursday one. In each exercise the students have to write a simple Python script to plot graphs of a function and its derivative (computed numerically) using matplotlib. The students upload their script and pictures of the plot to the VLE used in Maynooth, which is called Moodle.

In the manner of a TV chef announcing `here’s one I did earlier’, this a sample output produced by my `model’ code:

I wonder if you can guess of what function this is the derivative? By the way in this context `model’ does not mean `a standard of excellence’ but `an imitation of something’ (me being an imitation of a computational physicist). Anyway, students will get marks for producing plots that look right, but also for presenting a nice (commented!) bit of code

This afternoon I’m on Cardiff time but I was able to keep an eye on the submissions coming in to Moodle in case something went wrong. It seemed to work out OK, but the main problem now is that I’ve got 20-odd bits of code to mark! That will have to wait until I’m properly on Maynooth time!

Now, back to the grind…

Do you iTunesU?

Posted in Education with tags , , , , , , on January 23, 2012 by telescoper

I’ve spent all morning re-writing a grant proposal for the umpteenth time, so I thought I’d take a short break for a sandwich and take the opportunity to dash off a quick blogette on a topic of topical topicality.

An interesting Twitter discussion took place on Friday, instigated by Leighton Andrews who asked the apparently innocuous question why so few Welsh universities have put content on iTunes U? I suppose what sparked this off was that a new version of the relevant app had just been released last week. In fact I think there’s only one Welsh university that has any material on iTunesU at all (the University of Glamorgan).

My response to the question was basically that, at least here in the School of Physics & Astronomy at Cardiff University,  we don’t have the resources to put a significant quantity of the more interesting content (e.g. video lectures and podcasts) on this resource. For one thing, although iTunesU is available for both Mac and PC platforms from what I understand you need to buy Apple software in order to create content to upload, which means having to buy Apple products in order to do so. Some of my colleagues have Macs and/or iPads, but I don’t. I think Apple kit is overpriced and gimmicky, but some of my colleagues go even further and consider Apple corp to be an intrinsically evil outfit that we shouldn’t have anything to do with, on principle.

However, those opinions don’t really matter because it would only take a few people with (possibly) dirty Macintoshes in the whole university to set it all up and there are undoubtedly many, especially younger, people out there who would want to see content there.  See, for example, this blog post which shows that having appropriate stuff on iTunesU could have a significant impact on undergraduate admissions. Perhaps we should put our open-day talks etc there and use it as a kind of shop window for the School?

We do have quite a lot of online material already – deposited on a system formerly known as Blackboard but now called Learning Central. Most of us distribute written notes, problem sets and the like on there and I think the students find it quite useful. I don’t know for sure how easy it would be to transfer such material to iTunes, but it can’t be that difficult, can it?

The problem is with the more complicated content such as videos. I’ve experimented with video lectures in the past and quickly came to the conclusion that you have to spend an awful lot of time and money to do them properly, otherwise they are excruciating.  A single fixed camera recording a traditional 50-minute lecture is as dull as ditchwater to watch, and we don’t have the resources to do anything more sophisticated. I think 5 or 10 minute supplementary videos is the way to go with this.

There isn’t much specifically physics content on iTunesU from the UK, apart of course from the Open University which has posted a large amount of material.  Oxford University has also made some very nice things freely available, including lectures on Quantum Mechanics from James Binney.

But then the basic question is who benefits from doing this? Our own (fee-paying) students already get material online for free from Learning Central. Should we make this available for free on a worldwide basis? Contributing to the general education of the world’s population is surely a good thing for a University to be doing, but is it consistent with the New World Order in which universities are merely businesses and students merely customers?

Anyway, I’d be interested to hear any comments on the usefulness (or otherwise) of iTunesU from teaching staff, students and interested parties here or elsewhere. The comments box awaits…
