Peer reviewed Peer reviewed
Tobin, Kenneth – Journal of Research in Science Teaching, 1984
Investigated changes that occurred in sixth- and seventh-grade teacher and student discourse when teachers endeavored to implement extended teacher wait-time in a sequence of seven lessons related to probabilistic reasoning. Results indicated that teacher wait-time increased from an average of 1.9 to 4.4 seconds during the lesson sequence. (JN)
