Here is a good article about how a number of higher education instructors are using freely available online video to enhance the learning experience for their students:
I have similarly employed online videos that I didn’t produce myself into my own courses. Not mentioned in the article is a special educator’s video site dedicated to teachers, called TeacherTube. Although a lot of it is aimed more at K-12 teachers than higher education, you should check it out as well. Yet another source for inspirational and faith-based videos is GodTube (also known as tangle.com). Another useful site is Vimeo, although you may need to search a little harder to find what you might be interested in.
For example, here is a clever video on Vimeo, created by a high school senior as part of his class assignment, to encourage other students to take Calculus. Enjoy!
From the student author: “At the end of my senior year in high school, our Calculus class had nothing more to do after we had taken our AP exams, so our teacher tried to fill the time with a small “busy work” project. She wanted us to make something practical to help teach Calculus to other students. Lots of people just made posters with a definition on it, others worked a little harder and made a board game… Justin Hendricks and I made a rap. We recorded it and played it for the class before the thing was due, but we weren’t finished yet. We decided to make a video accompanied by a music video portion to show the class. Since we graduated, our video has been played every semester in everyone’s Calculus classes. Gotta love it.”
