Maybe it's just my old-school ways, but I personally can't stand it when a professor lectures from power point slides. A lecture where the professor essentially re-writes his/her notes on the board while explaining them does two things in favor of learning: First, it slows the professor down, keeps him honest (e.g. in a math-based course he is forced to check his work as he goes) and forces him to only put up on the screen or discuss what he (a human with human limitations in writing speed) can actually write himself. Second, it forces the student to actually participate in the lecture by writing his/her own notes from what is said and written on the board. A ppt slide lecture on the other hand requires very little effort on either party. Professors often put too much in their slides (more than can be discussed during an 80 minute lecture) and thus say too little about the material, leaving the student wondering which parts are important and which ones aren't. On the student side, it's too easy to just print out the slides ahead of time and sit passively during lecture, drifting in & out of focus, alternately paying attention to the lecturer and one's laptop, PMP or texting device. Ppt lectures promote laziness on the part of the teacher and the student, IMO. Granted you were talking about elementary school, not college, but it struck a nerve. Maybe some of what I've said might transfer over. :-) Maybe not. I must say though, that the 55" touch sensitive "smartboards" that our school has in some of its lecture rooms are REALLY cool. No chalk, no noxious ink, and the prof's notes go straight to pdf on the course website.
