My latest MOOC learning experience is called Learning to Learn, found at Coursera. The course uses many short videos for each topic covered. Most of the talking head videos are fairly basic with a green screen and basic graphics.
One topic covered in the MOOC is memory building. I found this supplementary video here an interesting look at how video can effectively be used with informal learning. How do we go from the talking head lecturer to a captivating presentation? The video is presented by US Memory Champion Nelson Ellis Back on how to create memory palaces to build and store memory forever.
