A small, but growing, revolution is occurring in the way that engineers and scientists design their presentation slides. This revolution advocates alternatives (based on multimedia learning principles) that challenge PowerPoint's default structure of a topic-phrase headline supported by a bullet list of subtopics. One such alternative is the assertion-evidence structure, in which a sentence headline states the main message of the slide. That message assertion is then supported not by a bullet list, but by visual evidence: photos, drawings, diagrams, graphs, films, or equations.
