Power Point software was a tremendous boon for teachers who grew up in the age of overhead projectors and acetate Vu-graphs. Praise God! For many years I tried to pack as much content into my Power Points as possible. Eventually I realized that the “more is not better” principle applied.
I enjoyed the creative challenge of summarizing the important points of a lesson and adding visual and audio media to the presentation. It was also comforting to know that I could fire up the Power Point and everything was there for the entire period. I would talk, embellish, ask them questions, tell my jokes, and my students would write.
In hindsight, I can see that I was too teacher-centered in my approach. With my longer presentations, my students wrote feverishly and developed writer’s cramp by the end of the 50-minute class. The more self-confident students would respectfully comment on the quantity of info they had to transcribe and ask for mercy!
For a 50-minute class, I now do my best to hold the number of slides to 8-12, including a Cover slide, a Review slide, an Overview slide, and a Conclusion slide. In addition, I have found that it helps my students if the content on my slides is incomplete, just the key concepts and the initial words of a sentence. At the Smart Board, I fill in the blanks manually. This allows them a more reasonable amount of time to transcribe the truly important content.
A word about the Overview slide: I have come to place much emphasis on this. I prepare this slide at the very end of my preparation of the entire lesson. Only then can I make a good judgment on what it should contain. I sit back and ask myself: If I have only five minutes to teach this class and one slide, what should I put on the slide?
Another step I take to be fully prepared for class is to synchronize my lesson plan with my Power Point. My lesson plan can be a summary of the entire reading. I cannot possibly cover all the material in the lesson. With a highlighter I highlight the words that I place into the Power Point. With a second different highlighter, I designate that material I shall manually write onto the slide during class.
I have found that making my Power Points more reasonable in length—trying not to cram extraordinary amounts of content into them—has helped my students to transcribe the truly important content. It forces me to distill the lesson into the most important points, themes, concepts, and essential questions. With this approach, I am getting fewer complaints about writer’s cramp. Overall, I feel my teaching format is much more student-centered.
