When creating a presentation, the first step is to choose the right multimedia for your purpose, audience, and message. Ask yourself what your main goal is - do you want to inform, persuade, educate, or entertain? Consider who your audience is and what their interests, needs, expectations, and preferences are. Think about the key points, facts, stories, or emotions that you want to convey and how multimedia can support your message. Depending on your answers, you can select the most appropriate media for your presentation. For example, if you need to inform your audience about a complex process, a diagram or animation could be used. If you need to persuade them to take action, a video or audio clip could emphasize the benefits or urgency of your proposal. If you are educating them about a new concept, an interactive quiz or game could test their understanding. If you want to entertain them, use a humorous image or sound effect to add some fun.
