I remember that I had this one professor in college who loved to use his multimedia projector in all of our classes. While most professors used the old traditional projectors and just showed us still images and text, he really went all out with videos and music, as well as showing us websites that were applicable to our course.
For myself the class was one of my favorites because the additional material really seemed engaging and was much better presented. It was easier to follow a lesson with more exciting moments and outside resources I could look back on.
Has anyone else run into great usage of a multimedia projector?
