This study of 1,601 students in the middle years of schooling (Grades 5-8, each student measured twice, 1 year apart) from 200 classrooms in 44 schools sought to identify factors explaining gains and declines in mathematics engagement at key transition points. In multilevel regression modeling, findings showed that compared with Grade 6 students…

The study, part of the Program on Education Policy and Governance Working Papers Series at Harvard University,…

The Third International Mathematics and Science Study (TIMSS) shows U.S. 4th graders scoring above the international average in both math and science, 8th graders slipping in both subjects, and 12th graders scoring at or near the bottom. Research indicates high expectations, a focused curriculum, better-prepared teachers, and balanced instruction…
