Understand and use the multimedia principles

I liked how you cleary supported your claim on how Dr.Ray did not follow the Modality Principle. His voice was not clear as you stated so the learning benefits of the narration aspect of this principle along with images is not followed. I also liked how you used an example from your past powerpoint presentation to show the Signaling principle by pointing out the images in your provided pictures.

I wonder if, in addition to your excellent blog post could you have maybe better defined how the Feedback Principle might help the learners by giving them positive/negative feedback on their performance for example from an assignment given by the instructor rather then questions being answered face to face.

Overall great post with nice images and references to Multimedia Priniciples!
