This document provides tips for creating effective PowerPoint slides and avoiding common pitfalls. It recommends outlining the presentation, using a clear slide structure with 1-2 points per slide in bullet form, choosing readable fonts and colors, keeping backgrounds simple, designing graphs and charts clearly, proofreading for spelling and grammar errors, including a conclusion slide to summarize key points, and ending with a question slide to invite audience feedback. Bad practices to avoid include long paragraphs of text per slide, small or hard to read fonts, distracting animations or backgrounds, and poorly designed graphs without labels or titles.
