q3 · i? · causal · r2

Randomized trial of the MQI Coaching model with 142 mathematics teachers (grades 3-8) from two Midwestern districts; 72 assigned to coaching and 70 to control. One year after coaching, videos of five lessons per teacher from a random selection were scored: "significantly higher than control group teachers on three MQI domains". No effect size printed.

"Teachers in the treatment group scored significantly higher than control group teachers on three MQI domains, including Common Core -Aligned Student Practices, Working with Students and Mathematics, and Richness of the Mathematics."
