The document provides tips for designing effective presentation materials like handouts, slides, and other visual aids. It recommends that handouts be designed with the audience's intended use in mind, such as note-taking or future reference. For slides, it advises keeping the amount of text brief, using no more than 3 points per slide, and ensuring the slides supplement rather than replace the presenter's own words. Other tips include choosing demonstrative visuals over clip art, integrating presentation aids smoothly into the overall presentation, and making sure any food or objects passed around have a clear purpose.
