Here are the slides from my NCTM St. Louis presentation in 2011, Looking at Class Through the Looking Glass, which explores how we can use instructional video to mirror lectures in mathematical classrooms. Unfortunately, I do not have an accompanying report for this talk, and the slides don't stand alone well. This talk is similar to previous talks, though - I Capture the Classroom, Making Math Move, and Teaching with the Tube - for which I have either video or accompanying reports on my website, www.apsu.edu/smythe/presentations.htm.
