The thread about technology in the classroom got me thinking..... I just got a projector installed in my room. I'm also supposed to get a document camera in the near future. I'm THRILLED about the document camera...I know I will use that a TON. But what are some ideas for the projector?? Power points and videos from the internet (united streaming, etc) are all I can think of, but I don't really know what they 'do'.
