I use PowerPoint for my W1111 lectures. What's wrong with board-writing? Do I hate chalks? I sure don't! My clothes don't like chalks, especially the black ones, but I am okay with chalks. Actually, I really feel writing on the board slow down the lecture and will actually make the lecture clearer to the students. However, on the same time, I hate to turn my back to my class and I hate to watch my students copying down my board-writing. I think notes-taking is a very positive way of learning during lectures. But notes-copying is not. I am trying to balance between the board-writing and PowerPoint by putting definitions and graphs on PowerPoint, while things I would like my students to actually write down on the board. I think it works okay except my lecture preparation becomes longer.
