Research shows that slides which use the assertion-evidence structure (a full-sentence assertion heading directly supported by visual evidence) are much more effective than typical slides. In this activity students create a series of assertion-evidence slides to support a claim. Students are paired using two “Cards Against Humanity” style decks of cards to create a ridiculous claim. Student teams then create a slide show which includes three assertion-evidence structured content slides to support their claim. Students gain practice constructing assertion headings which support their claim, selecting various kinds of visual evidence to support these assertion headings, and visually citing that evidence.
