I don't remember if I've already tested this, and I can't be bothered to search the archives to find out. I should actually be working right now.
Go!Animate is an online tool for creating flash animations with relative ease. I say relative because it's still a fairly time-consuming process, and it isn't quite as intuitive as it likes to think it is.
I created this animation because in Spanish I, our most recent unit was about basic socializing. The exam for the unit is a one-on-one conversation. I have one student whom I know knows all the stuff, but I don't think I've ever heard her speak individually in class. My thought was that, instead of having a straight-up conversation with her, she could help me do the voice-over work with this cartoon. It turns out that you can't directly record voice-overs into the video--you have to use a different piece of software to record them, and then import them into the animation. If your objective is creating videos, that's not a problem, but if your objective is getting reluctant students to speak, you add a whole layer of abstraction and hassle that you don't want. So that idea isn't really going to work.
Anyway, without further ado, two methods of sharing the video: the link,
and the video embedding:

Update: You can sort of record your own voice. You call a telephone number, and it will record you, and by some mechanism, it ends up attached to your video. It's still not as good as just pressing a record button and talking to the computer, but it might be able to work.
