Looking at lecture capture led me to ask questions about the technology’s effectiveness. I can’t help feel that lecture capture is counter-intuitive, since we know transmission based learning is less effective than active learning (so, why would we invest more in it and replicate it?) and we know that concentration spans for online engagement don’t readily lend themselves to hour long broadcasts (my own concentration sees frustration after 15 minutes!). Nevertheless adoption is on the increase and students clearly appreciate the opportunity to apply catch up TV principles to learning – they value the flexibility.
As lecture capture heads towards the mainstream, I thought it useful to look at the evidence of the benefits and challenges of this technology, especially in light of a prediction that we may begin to move away from capturing lectures to viewing lectures as performances – something Professor Phil Race constantly emphasises with the idea of making the lecture unmissable and engaging.
My reading notes can be downloaded but the headline points were:
- More research is needed in to actual, rather than perceived effectiveness of lecture capture.
- Students appreciate lecture capture and believe it helps learning but the actual impact is unclear. Critically there is little or no evidence that lecture capture really impacts performance. Some subsets of users appear to show higher scores, but this may be associated with their diligence rather than the impact of heavy usage of downloads.
- The circumstances in which lecture capture is effective and the reasons for it are also unclear. Research suggests that content heavy subjects are best suited to this technology and interactive subjects less so, and this makes good common sense. By implication then, this point raises the question would lecture capture lead to a less interactive delivery style?
- Lecture capture is suspected as having a connection with more effective note taking and students appear to selectively watch lectures to address tricky concepts. These recurrent findings, irrespective of the growth of lecture capture, point to the value of addressing how students take notes as an academic skill and raise the question of how media can be used to address difficult concepts in watchable and debunking, even (dare I say) enjoyable ways.
