Great way to get students hooked on a topic or concept
I am not always keen to use videos in the classroom, but teaching Music over the past two years I used this site. I used both the regular and the junior sites, to explain concepts in music that were otherwise abstract. Very useful, and the kids love it.
How I Use It
I used the videos to either introduce a concept or to reinforce understanding of the concept. I used Apple TV and projected the videos wirelessly through my iPad. The students loved to complete the quiz at the end, and I passed the iPad around to let them take turns choosing the answers. They love Moby.
