Having seen this (interesting article btw) and some of the negative press about Cambridge uni using on-line lectures for all lectures next year, I thought I'd write a thread on this topic.
Before concluding whether on-line lectures are good or bad, I'd ask:
How effective are lectures (in terms of retention of info?)
What proportion of lectures are truly interactive?
What is the avg lecture attendance rate within progs/schools /HEIs /nationally?

Problems with lectures have been reported extensively in the pedagogic literature. Even in the 1970's, Donald Bligh called for the end of them…
And many of us are aware of the "Death by PowerPoint" phenomenon

The Learning pyramid theory places lectures at the bottom in terms of average student retention rates
A BBC report from 2016 questioned why lectures were still being used. It refers to one study from Harvard where lecture attendance falls from 79% at term start to 43% at the end…
Recent UK data would be useful to see
Whilst some lecturers adopt an interactive style, including use of software programmes such as Turning Point or Cervix, this is probably not the norm for most
So, what are the potential benefits of on-line lectures?
One of the benefits of blended learning is that students can study at their own pace at a time that best suits them.
(Is a 9am lecture the best time for all to learn?)
Access to a library of on-line recorded lectures allows students to listen to content on multiple occasions - very helpful when trying to understand and learn the more difficult concepts.
They can also listen to content whilst on the bus or train.
Reflecting on my own time as a student (20 years ago), access to a library of lecture recordings would have been very useful when:
: I missed a lecture (as catching up from a friend was never the same)
: I couldn't make sense of my lecture notes
Lecture capture software can also monitor how many times (and how long) a student accesses a particular recording. Prog teams can review these data to identify the most and least popular topics to inform subsequent curriculum reviews
Using on-line lectures frees up timetable and lecturer time, possibly allowing more workshops, tutorials, seminars, work-based placements etc.
Some content (e.g. laws of thermodynamics) is unlikely to change each year, so delivering this on-line saves staff time long-term
In summary I am in favour of on-line lectures as long as
: Guidance given on the order to view them
: They're followed up with activities to consolidate learning and these are interactive with feedback provided by the lecturer
: Poor student engagement addressed
Continued social distancing will bring a big challenge for HEIs. On-line lectures can free up timetable time to facilitate smaller group F2F teaching that allows compliance with social distancing.
Licve, on-line workshops are possible via Adobe Connect, Zoom, MS Teams etc.
Typo from auto correct meant Veevox not cervix!! 😂
