Ask HN: Why are the most MOOCs videos showing the lecturer in the video?

because videos with a "talking-head" are more engaging that slides alone.
as was reported in this study:

"Our main findings are that shorter videos are much more engaging, that informal talking-head videos are more engaging, that Khan-style tablet drawings are more engaging, that even high-quality pre-recorded classroom lectures might not make for engaging online videos, and that students engage differently with lecture and tutorial videos."

Yes, some research is welcome.
I wonder the same thing as well. This goes for any sort of screencast. I reckon that it's something that was adopted from the gaming world? The short answer is likely: because branding.
Being recognizable is a point for sure.
What is the point of that?
I assume that's relatively something new, since KhanAcademy old tutorials are not like this?
