[PSTUM-list] More on Video Case Studies

PSTUM List, I have two related requests for information. 1) I'm working on assembling a library of video clips of teachers in action for use in TA training. My initial goal is to index or code the clips in a way that facilitates finding a clip that features, for example, ...the definition of the derivative or ...students presenting work at the board or ...a teacher with particularly effective oratory skills. I'm wondering if there are any existing coding schemes that I might use to help me index the clips in this way. Any ideas? 2) I'm leading an upcoming session (tomorrow actually!) in our TA training seminar in which I plan to present a few interesting video clips from this library-in-progress and lead a discussion about the clips. Has anyone led a similar session (for TAs or other groups), and, if so, what types of questions did you ask to help direct the discussion? Thanks in advance!
