I have found PowerPoint to be too limiting. I avoid using PowerPoint. Rather, I have found that I can project images onto a whiteboard and use the markers to highlight important points. This allows, for example, students to see how a criminal statute can be "redrafted" into a criminal charge, or a sentence from a student's writing project can be improved. I agree with other points in this discussion that PowerPoint is only a tool and not an end in itself. When prepping a class session, it is easier for me to set up web pages in many tabs or student projects in several word processor pages and to switch between them as needed on the fly depending on the course of the discussion. This also allows the students and me to be less rigid with a lesson plan and to expand our areas of instruction and learning based on student questions. Could I use PowerPoint for the same purposes? Probably. But why? Browsers and other applications on a powerful computer are just as effective, perhaps more effective.
