I feel that Powerpoint can be effectivly used in Elementary schools. Its a great way to teach young kids who do not learn well by just hearing a lecture. It is another way to present the information to insure that more students understand the material. However, it can have some negative effects also. If the teacher puts on too many words and not enough graphics or makes it too long than he/she could quickly lose the attention of the students resulting in the powerpoint doing more harm than good.
PowerPoint and other presentation software can be a great tool for teaching at any grade level. The teacher just has to adjust the presentation to fit with their particular grade level. Take a history presentation for example. In an elementary class you would have the basic facts and a lot of pictures and graphics to support the information. You would not lose the attention of the students. In middle and high school you are able to put more information on the slides and go more in depth with the material as you move up. You would still want to include graphics to make it interesting, but you are able to put more information because they can pay attention for longer periods of time, most of the time.
I am curious to see the development of document cams and how they will be used in classrooms. They were just beginning to come into use when I was in high school but were still not that popular because of the use of computers and powerpoint. It will be interesting to see if and how teachers use them or if they will just fade away due to the use of computers and other technology.
