A training program for changing teachers' classroom behaviors was developed after observations indicated that students gained in reading skills when teachers spent more time instructing, discussing homework, and providing supportive feedback. During workshop sessions teachers were encouraged to: (1) decrease time taken to make assignments and increase instruction time; (2) ask short questions and give immediate supportive feedback to responses; (3) distribute questions among the students, choosing questions each student could most likely answer; (4) give short quizzes designed to allow the students a high rate of success; (5) have the students in the low reading groups read aloud; (6) encourage more reading aloud, discussion, and review, and ask for fewer written assignments and less silent reading; (7) minimize intrusions from outside the class; and (8) keep the number of choices students may make at a minimum. A posttest of student reading achievement in classes where the teacher had attended the workshops showed that the treatment group had higher grade gains than the control group. (JD)
