Every year, it gets harder and harder to find affordable sources of instructional videos for use in K-12 schools. Fortunately, San Antonio ISD has a subscription to PowerMedia Plus digital video distribution system. All students, staff can access PowerMedia Plus videos at school and at home. Yet, it doesn't hurt to be aware of what other video resources may be available at no charge via the Web.

While some are already familiar with Encyclopedia Britannica, there are other free digital video resources. Mike Falick's Blog points to one possible alternative--SpaceTime TV. This service features video from a variety of resources--some of which may be blocked--from sources such as PBS, YouTube (blocked), Hulu, and National Geographic. It appears to be focused on videos around these topics: Environment, History, Nature, Space, and Technology.

And, there are other sources of educational videos, including

• The Open Video Project
• The Future Channel
• Springfield Public Schools

The folks at the San Diego County Office of Education. have tons of great resources, among them, the 3 bulleted links above. Do you know of other sources of educational videos?

Here are a few more...

• Oklahoma WWII videos that Wes Fryer (SpeedofCreativity.org) has been instrumental in gathering/recording.
