I really like the explanation of the signaling principle and the segmenting principle. You explain the principle in detail and give an example of them. Your Twine story is very interesting and follows the multimedia learning principle “keep it short and simple”. Finally, I wonder if maybe you can explain more about Twine story is more convenient than PPT, not only in a history class.

Overall, this is an excellent analysis of the Twine story.
