The document provides 10 tips for improving presentations using slides: 1) Slides should supplement the presentation by providing visuals to reinforce key points, not introduce new information. The main message and supporting points should be presented verbally before the slides. 2) Slides should use consistent formatting, language, colors and themes to clearly relate to the topic being discussed. Color coding can indicate transitions between topics. 3) Balance the amount of text on slides - too much can distract from the verbal presentation. Use bullet points and shorter sentences if needed. 4) Photos and images can effectively convey meanings and require less explanation than text alone. 5) Effects and transitions should be used subtly to avoid seeming irrelevant or uninteresting
