I saw 10 tips for doing the powerponit.
But I think these five tips are the most important.
First:
Good contrast with the background is essential to make your text easy to read.
Second:
Some concessions can be made for a photo album, since most pictures will be on screen for only a short time.
Third:
Use photos, charts and diagrams only to illustrate key points of your presentation. They add a nice break to the material, and when used correctly, can only enhance your oral presentation.
Forth:
By using bullet points for key information. Keep the most important points near the top of the slide for easy reading in the back rows.Speak to the audience, not to the screen.
Fifth:
Use key words and phrases and include only essential information to keep the audience focused and interested. Be prepared for questions and know the answers.
Hope it is uesful to me !!!!!
