A rigorous study that takes advantage of lottery-like features in New York City’s high school admissions process demonstrates that new small public high schools that are open to students of all academic backgrounds have substantial impacts on rates of graduation with Regents diplomas for every disadvantaged subgroup of students that was examined.
What Two Rigorous Studies Tell Us
This synthesis reviews findings from two rigorous, large-scale evaluations — the Professional Development in Reading Study and the Middle School Mathematics Professional Development Impact Study. Both interventions had only limited effects on teachers’ knowledge and instruction and no impacts on students’ test scores. The report ends with suggestions about how professional development might be improved to achieve better results.
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.
