This document provides tips for creating effective PowerPoint slides by avoiding common pitfalls. It recommends outlining the presentation, using a consistent slide structure of 1-2 slides per minute with 4-5 points per slide written in point form. Font should be at least 18 point and easy to read, and color should contrast sharply with the background. Graphs are better than tables for presenting data and should always be titled. Proofreading slides for spelling and grammar errors is also advised. The conclusion should summarize key points and suggest future work, and slides should end by inviting questions.
