Since I couldn't get the embed thing to work, here's the URL for my ScreenToast: http://www.screentoaster.com/watch/stUEpWQEdIRFtZSFVZX1JaVldd
I had a lot of trouble getting the audio to work, but after some superhuman rescue attempts by Deb Friedman, I was ready to go for my 5th attempt at recording the same no-script how-to video. (So if I made mistakes or repeated myself, blame the repeated efforts.) By and large, however, I like this THING a lot! Now that I've successfully completed it, I can imagine making many more instructional videos to post to our website for new staff, for mini-lessons (how to do a mail merge, for example), how to set up your library account so that you can track your circulation, how to use SWAN to find a book -- and then how to get the library to order it for you -- and so on , and so on, and so on.
For classroom teachers, this could be a great teaching tool -- but for students, what wonderful practice in oral expression. Good for learning how to deliver information verbally (a Speech component of the English curriculum?), and also good for information technology skills -- how to "do" technology language and literacy. If they can teach it, they will know it themselves. I would limit the length of a video presentation - to teach how to be concise, and also so that the "teachers" don't lose their audience. So pre-planning (storyboarding, practicing, etc.) are important.
All in all, a good thing!
