These 2 DVDs contain 2 hours of un-rehearsed live student demonstrations in 1st, 4th, and 6th grades and two Q&A sessions with teachers at a diverse elementary school in Ft. Worth, Texas. Shot using 2 camera angels and professional audio recording, these videos really give a great idea about what a lesson in Highly Effective Questioning is supposed to "look like" in real-life. The DVD format enables excellent video production and enables you to project the demonstrations onto a large screen for a faculty-review as a group. There are incredible moments that show the power of systematic (not random!) questioning in getting students to scale the "cognitive scaffold" and get to new moments of understanding. .
