College faculty members have recently begun creating homemade videos to supplement their lectures, using free or low-cost software. These are the same technologies that make it easy for students to post spoof videos on YouTube, but the scholars are putting the tools to educational use.

After all, the students already sat through the lectures once (the professors hope). In this article, the author discusses how educators are embracing do-it-yourself technology to make short online videos to supplement their lectures.
