Although class size reductions are often proposed as a way to improve student learning, research does not indicate that smaller classes will necessarily produce improved student achievement. Class size effects on student learning vary by grade, pupil characteristics, subject area, teaching method, and other learning interventions. References…

Summarizes research findings on a Tennessee experiment in small classes for primary grades--Project STAR (Student/Teacher Achievement Ratio)--and on similar projects in other states. Discusses effects on student achievement and classroom discipline, effects of small classes versus larger classes with teacher aide, costs, long-term impacts, and…

Researchers followed up on fourth graders from Project STAR, a reduced class size experiment. Using norm and criterion-referenced achievement tests and teacher ratings of student effort, initiative, and behavior, they found significant small class carry-over effects on every achievement measure and significant participation differences in small…

Tennessee's Project STAR (Student Teacher Achievement Ratio), a large longitudinal project involving students in kindergarten through third grade, has provided important information about class-size effects on pupil achievement and development. The project showed that small classes provided higher student outcomes and better student behaviors than…
