powerpoint in the classroom

Powerpoint presentation are becoming a norm in our classroom at least at the upper levels. In college very few do not use them, and even a few professors are requiring them. In High School with the wide spread use of the smart board more and more teachers are finding them handy. In my little inner city school we just got a smart board and its just the one but its a start. I believe that at some point it will be the primary way we teach. At the touch of button you can connect with videos or actual photos of a place it is beautiful. There are some chances for abuse or I should say a lack of teaching. It is very common for a teacher or a presentor to just start reading the powerpoint slides and this isn't teaching this is presenting.
