There is a wealth of free educational multimedia online, if you know where to find it. Below is a sampling that I have found to be pedagogically valuable. This list is periodically updated, so let me know if you find any other good sites to share with our colleagues. You can reach me easily via my Contact page.

If you are unsure of your rights and responsibilities under the “Fair Use Act” provision of copyright law, see this concise explanation by the US Copyright Office. They’ve done a good job of explaining the details all educators should be aware of. Acting within the constraints of this provision, it is still possible to assemble a huge library of multimedia resources that can make your classes more visual and dynamic. Over the years I’ve actively sought to build my collection, I’ve accumulated gigabytes of material.

On that same topic, educators should be aware of the wealth of copyright-free material available at Wikimedia Commons. At last count (2015) they listed over 26 million media items (photos, drawings, animations, videos, audio, text). Their huge database is easily searched, and growing every day.

Students love this stuff. Having it all there on your classroom (or home school) computer is a great tool. It’s the practical equivalent of a 3D moving chalkboard, supplementing your traditional materials, allowing improvisational breaks from the routine, and providing visual answers to student questions. Using multimedia in your classroom is guaranteed to expand your repertoire of educational methods. Here’s a list of online resources that focus on STEM (Science, Technology, Engineering, Mathematics). I’ve tried to avoid sites with excessive advertising, but if it’s a valuable (read: high traffic) site, you’ll probably run into a few ads.
