Plan your presentation. Make an outline. Consider a compelling introduction and how you will keep the audience interested throughout your talk.
Think about your key points. What do you want the audience to learn or remember about your talk? Focus on building your presentation around those points.
Remember that the slides are there to support what you are saying, they themselves are not the presentation. Plan your presentation first, then make your slides.
II. Putting together your PowerPoint
Consider making only one point per slide.
Avoid too many bullet points and too much text. Consider only images or single words, and then let the audience's attention lie with you and not the slide.
Using images in your presentation can be effective in keeping an audience interested and conveying information in a more powerful way than simply words. But make sure you aren't violating copyright! You can used image licensed under Creative Commons licenses. For guidance in how to use CC-licensed images, click here. See the box in the left-hand column for some resources for finding creative commons images to use in your presentation.
Use large text and high quality images. Avoid background colors that obscure the text on your slides.
III. Delivering your presentation
Practice you presentation in front of a mirror, or better yet a live audience.
Remember to project your voice and speak clearly. Make sure to pace yourself.
Don't read directly from your slides. Remember to face the audience rather than talking to the slides.
Don't over-prepare. Try to keep the presentation conversational. Consider engaging the audience with questions, humor or story-telling.
