Creating effective multimedia presentations requires careful planning. The presentation should start with an attention getter, have visual aids to support key points, and handouts distributed after. When creating slides, start with text then select backgrounds, fonts, images and effects. Slides should generate interest, highlight points, and simplify ideas. The writing process involves prewriting to analyze the situation and audience, researching to learn templates and visual aids, and revising by rearranging, proofreading and evaluating the presentation. Effective delivery requires preparation, rehearsal, and checking equipment and body language.
