I like the explanation of the primary thoughts about multimedia learning and how the thought changes now. I agree that Zoom and Brightspace is a nice application of synchronous teaching. I wonder if, there could add images of face-to-face and online communication? Two images could compare the difference of teaching methods directly and clearly.

This blog is easy to understand. Good luck with your future studies.
