Why there are so many vid lectures in online learning,why there shouldn’t be

The article starts off well. It highlights the unquestioning use of video for online courses, and imagines better ways to promote learning. It goes on to cite a report called "Video and Online Learning: Critical Reflections and Findings From the Field" and discuss 3 recommendations from that report. This was getting interesting.

Unfortunately, 2 of the 3 recommendations were about how to do video. "Make the Best Use of Video as a Medium" and "Consider Lightweight and DIY Approaches" to making video.

Thought I was going to get some insight here. Turned out to be quite disappointing.

I thought that videos and lectures were always known be a supplement and introduce concepts and ideas. The real learning is the hands on labs, assignments, and real-world experience which you gain the most value from. But I still think the lecture has its place. Nowadays, video production is cheaper than it ever has been so I don't understand that argument either. There are people making feature length films with a 1000 dollar camera and 500 dollar software.
