Questioning, Crystal Proctor
This piece shows several parts of Math teacher Crystal Proctor’s Geometry class, which uses the Complex Instruction methodology, a structured, research-based approach to student collaboration. The first 2 minutes and 45 seconds demonstrate Ms. Proctor’s approach to questioning, which includes frequent use of “why …?” and “how do you know …?” to elicit explanations, as well as “what do we call that?” to encourage the use of mathematical vocabulary.
