Between 1985 and 1989, the Student Teacher Achievement Ratio (STAR) Project studied the effect of class size on student achievement in Tennessee schools. The study examined: (1) small classes of 13 to 17 students per teacher; (2) regular classes of 22 to 25 students per teacher; and (3) regular classes with a teacher's aide. The sample included…

Examines second and third grade data from Project STAR, a reduced class size study. Observers viewed teachers, some of whom received inservice training on effective teaching and class type. Observers' narratives and ratings of class activities and interaction indicated little change in teaching practices regardless of class type or training. (SM)

But there are still significant gaps in knowledge about many aspects of their deployment and impact. The Class Size and Pupil-Adult Ratios…

Although experimental results indicate that smaller classes promote higher achievement in early elementary school, the broader literature on class-size effects is inconclusive. This seeming contradiction raises questions about the generalizability of experimental evidence, an issue that this article addresses by examining the effects of class size…
