Before you begin to prepare lesson materials, think about the content you want to introduce and the students to whom you are presenting it. Even though the material is presentational in purpose, is there a way for you to involve the students more actively? Can you incorporate images, sounds, or a video clip or two? What colors appeal to the students? What size text will you need to use? How big should the images be? How much text and how many images should you put on any one page? How many colors on one page are too many? Do your students have any special needs? Where do you want the focus of your students to go? Of the tools and resources you have, which are the best ones to teach the information, concept, or process you want the students to understand?
