I mentioned a while back that I thought a Flip camera may be a pretty decent assessment tool. Today, I had one group having a great discussion about distilling the process for finding a perpendicular bisector into a few steps. I grabbed the Flip and sat down with them. Forgive me if you can't read their steps very well, I'm still working out the kinks.
I think I see some real potential here. Kids can record themselves and then we can go to After Effects and add some stills of their work. I don't know, maybe I'm getting ahead of myself. Feedback welcome necessary, please.
