Tips for Making Effective PowerPoint Presentations
Use the slide master feature to create a consistent and simple design template. It is fine to vary the content presentation (i.e., bulleted list, 2-column text, text & image), but be consistent with other elements such as font, colors, and background.
Simplify and limit the number of words on each screen. Use key phrases and include only essential information.
Limit punctuation and avoid putting words in all capital letters. Empty space on the slide will enhance readability.
