I frequently use the Internet to have my students do more normal things but add an educational goal. For example right now, they have scoured the Internet for a picture they'd like to describe. Next, they are going to open Creative's WaveStudio and describe the photo for ninety seconds. Lastly, they'll save the photo and the audio file in a special class folder so others can listen and view the results.
All the while, I can comfortably sit at the instructor's computer in front of the room. This is rare as I'm usually all over a classroom when teaching. Presently, from the front desk, I can call up what is happening on every screen in the room. The program is called NetSupport School and I've found that spying is rather fun!
