On May 17, 2007 a screencast of Google.com math features was created during the Global Learners Professional Development. The screencast was captured within SmartBoard software and then uploaded to youtube. I have embedded the video here as an example of how this can be done. The video could be improved by using better examples. However, I can see the value to our students of screencasts just like this. Imagine a scenario where a student missed class or just didn't follow what your explanation of an Algebra problem. If the screencast of the problem being worked were captured and loaded to a class blog the student could go back at any time and review. Anyone interested in trying this? If you are post the result on this blog.
