This is an interesting article on the effectiveness or un-effectiveness of powerpoint.
Learning styles are important to understand and I wonder what would happen if we didn’t use PowerPoint as slavishly as we do. Some times if feel like we make our selves slaves to the program instead of making the program serve us. Just a random little thought. I personally like the use of PowerPoint if it’s simple and subtle. I think it can be a great help to understand.
Something to think about.
