I like how you explained what was wrong with Dr.Rays powerpoint. Dr. Ray not following these principles as you explained such as Embodiment principle which made his powerpoint harder to follow. I also enjoyed the pictures you added on your post.

I wonder if you could of added some questions or comments on screen in the video to allow the viewers to show there understanding of the concept.

Overall really nice blog post! I really liked the pictures you added in your blog post! Great Job Kejia!

Understand and use the multimedia principles
