Making an Emotional Appeal. While most academic presentations are meant to be rational rather than emotional, whenever there is an element of emotion in your presentation, video can help. It works well as an emotional medium, using the elements of dramatization and demonstration along with music and powerful visual evidence to evoke strong feelings in an audience. In the realm of the emotions, a picture often is worth a thousand words. The incredible photographs and documentaries made during the Great Depression, for example, bring the hardships of that era to life for students who have never known hard times.
Video shines when it deals with the visual, the dramatic, and the emotional.
Unfortunately it becomes much less effective when it gets away from those strong points. You need to be aware that video is not especially good at verbal presentations, at presenting abstract, nonvisual information, or at making an intellectual argument. Talk Talk Talk. There has been an unfortunate tendency in recent years to create video programs which consist of nothing but people talking. Certainly, if the speaker is someone the audience would stand in line to hear anyway, this can be quite interesting.
