Whilst I’m normally on this blog talking about Numbas, this post is dedicated to something else that I take a keen interest in: lecture capture. It describes a pilot project that was funded by the NUTELA group to deploy short, re-purposed ReCap videos in a large engineering module. These were made available to students in addition to the full length ReCap lecture capture, and sat alongside formative tests associated with the content.
A disclaimer, before I go any further… this is a dump of my current thoughts on the topic, and it will save the next person who asks me about ReCap/short videos from suffering me talking at them for an hour! As a result, it’s part project report, opinion piece and tutorial! Despite lacking any focus whatsoever, I hope that you find something interesting…
I have been interested for some time in the use of lecture capture. I originally wasn’t a fan, mainly citing a hatred of hearing my own voice! I have managed to get over that though, and spend a lot of time in computer clusters, where I see first-hand the benefits of ReCap for students. I am particularly fond of telling the story of asking a student which ‘psych-up’ music he was listening to on his headphones before a big class test… he was listening to me giving a lecture!
So I read with interest the results of the 2017 NUSU survey “How Students use ReCap”, and in particular these two results:
Whilst the opportunity to catch up on lectures is clearly very beneficial – in particular, as the associated report mentions, for students with disabilities and those competing in elite sport (and I’ll also throw in those with families or caring responsibilities) – it does not appear to be the primary use of ReCap. This aligns completely with what I see in our computer clusters, which is predominantly students using the resource to prepare for class tests and exams.
Let me reiterate that I’m a big fan of the ReCap provision, before going on to make the following two observations:
1) Our current set up of teaching resources is often very siloed within the VLE. Typically a module might have a separate Blackboard folder for each of lecture notes, additional resources, formative assessments, whatever else… and certainly the default is a separate folder of ReCap videos. But if students are revising a topic for an exam, putting practicalities aside, it seems to make sense for the video content on a topic to sit side-by-side with the other course material.
This was just one of the motivations for our course material tool “Coursebuilder” (which will be the topic of my next blog post here as it happens), to have a stronger integration between different course resources. And it is surprisingly easy (after discovering the method as part of this project) to embed videos next to your lecture notes in Blackboard itself. See the Process for creating videos section below.
2) Slightly more pertinent to this post, our ReCap videos are presented to students as a separate video for each teaching session. Again from a practicality perspective, this seems like the only sensible thing to do, but from the student perspective, is this box-set of lectures the best way for the “series” to be divided, if it is being used for revision? Often topics are split over multiple lectures, or multiple topics are covered in one lecture. In maths, the subject of this project, lectures often contain distinct sections of theory and application/exercises. The student might only be interested in one of those when they come to revise.
A note on the indexing of ReCap videos for mathematics… You may have noticed that ReCap videos containing PowerPoint automatically generate a list of contents. Panopto basically identifies section headings in the presentation. In mathematics, it is rare to see a PowerPoint presentation, they are usually delivered using the visualiser or whiteboard, or as a LaTeX document. Content information can be added, but only manually after the fact.
Last Spring, colleagues in engineering maths, David Swailes and John Appleby, approached me to discuss short videos in the ENG1001 Engineering Mathematics module. David had heard of the work of Professor Chris Howls at the University of Southampton, who had successfully used short personal capture videos to enhance a calculus course. We discussed several possible formats for short videos, including something on the lines of what Chris had done, but the nature of the ENG1001 module lent itself to a slightly different and straightforward approach: to re-use a previous year’s ReCap collection. This is because almost precisely the same module content has been delivered (very successfully) over a number of years; last year’s ReCap videos would be almost identical to this year’s.
