Certainly well-edited work is better, but should lack of time prohibit me from trying to engage my students with a video?
My expertise is nowhere near Dr. Tanton’s, but does that mean that I have nothing to offer?
Sure, I could borrow videos, and I do, but what kind of example am I being if I never offer any of my own creations for the community to hone? Plus, the students enjoy hearing the stories of how I thought of ideas and how I made the video.
2012 has taught me that there is value in the effort, because it isn’t just about the students learning, but I have much to learn as well.
