Group+2+Signaling+Principle

The signaling principle indicates that the presenter needs to provide an outline of where the important information is located or what the important information actually is in the presentation. This presentation does not indicate what is important as the viewer goes through the presentation. Several slides are collections of pictures and while I think I can tell what the intent is, I am merely speculating.

This slide has an abundance of content, but as you go through the content it becomes difficult to tell exactly what the author wants the learner to retain from the presentation. While most slides have titles that indicate what the topic of the slide actually is, those titles are frequently smaller text than a title ought to be and they are easy to confuse with the rest of the text on the slide.
