This report presents first-year results from the Middle School Mathematics Professional Development Impact Study, sponsored by the Institute of Education Sciences. The professional development programs for seventh-grade math teachers had an impact on one measure of teacher practice but no effects on teachers’ knowledge or student achievement.
This report presents findings on the effectiveness of two specific professional development strategies on improving the knowledge and practice of second-grade teachers in high-poverty schools and on the reading achievement of their students.
This paper illustrates how to design an experimental sample for measuring the effects of educational programs when whole schools are randomized to a program and control group. It addresses such issues as what number of schools should be randomized, how many students per school are needed, and what is the best mix of program and control schools.
