If we can't take credit for unexpected teaching we'll look like flops most of the time. I think the most/best/deepest thinking my students do is unexpected and unplanned. I refuse to think that makes me less of a teacher!
The anarchist classroom you have created this year is what led to the phenomenal panels and discussions your students had. They couldn't have done that six months ago. If that fact also means less work for you, that's just a bonus.
Do you think it is possible to overthink what we do as teachers? Can we overplan and overanalyze and therefore miss out on opportunities that could have been stupendous? It's unlikely to ever happen to me, but I remain curious.
