Transparencies are a separate medium from print and serve a different educational purpose.
Know your purpose. For example, transparencies allow the teacher to face the audience, keep the teacher structured, and slow down the pace of the lecture to allow students to keep up. They can help students structure their notes. Use transparencies for outlining material. Simplify and edit your text.
