Here is a crappy video of a spinning wheel.[vimeo http://vimeo.com/38948137]
I needed one for Calc 2, where we are studying parametric equations. I Googled “spinning wheel video” and found nothing that would be at all useful.
Now it exists. Hopefully someone will take the time to make a better one someday. And hopefully they’ll let me know once they have.
Until then, I am a bit embarrassed at how low the bar is for instructional innovation in higher ed math.
And if you want the QuickTime file so you can pause, edit and generally have your way with it, shoot me a note on Twitter and I’ll make it so.
