In an effort to improve student achievement, a group of middle-school teachers at an underperforming school developed a schoolwide literacy plan. As part of the plan, they agreed to model their thinking while reading aloud. Eight teachers were selected for coaching related to think alouds in which they exposed students to comprehension strategies that they used while reading. The achievement of their students was compared with the achievement of students whose teachers participated in the ongoing professional development but who were not coached. Results indicate that the coached teachers changed their instructional practices and that student achievement improved as a result. (Contains 1 table.)
