Click on the arrow within the video window below to play a music video that I made by combining PowerPoint slides from lectures about World War II and mixing in music that my students like (and is legal by the way). The PP slides are simplified ones from what were displayed during class. The process for making the music video was by a commercial company called Animoto. http://animoto.com Teachers can apply for a special educator classification and gain access for you and students in the class for six months. Their site provides the legal software to use in mixing witht he video. Go to the webiste and they have plenty of information and provide other samples. This is powerful stuff. My students said that it was useful for a last summary of material that they had been studying in preparation for the unit exam. Enjoy.
