In this blog post, Kira identifies the principles that Dr.Ray Pastore did not follow in his MML principles video. A great explanation was given as to why the modality multimedia principle and the embodiment principle were not followed while also making a fair point on the ability of experts to accommodate everybody’s preferences. They also talk about how they used the signaling principle in their past PowerPoint project to provide their audience an easier way for them to understand and keep track of the presentation. By providing photos they are able to grab the attention of their readers.

I wonder if Kira could further explain the signaling principle and how it corresponds to the PowerPoint. This will give the audience a deeper understanding of the topic. Overall this was a great read.
