I just found out about this and it totally "rox my sox" as the middle-schoolers would say! I was able to create a little movie of my computer screen as I talked my students through how to sign on to their account and access important information for class. I do this with the LCD projector on a regular basis, but it is nice to have the ability to create a series of tutorials for the students. I might try and do this for next year as I think it will save lots of time that was spent getting the kids to sign up. They had a paper to read as they worked through it, but I have found that showing them first, and then letting them do it goes much faster and they have far fewer questions about the process.
