Bryce Hedstrom is conducting a one hour google hangout tonight, Monday January 12 at 7:30 MST. Bryce is an expert TPRS teacher who regularly presents at national conferences. Check out his website that has lots of great free and low-cost materials. My personal favorite is his ebook El cuento trágico de Mark, which really helped me understand how to teach upper-level students.
