School Reform, School 2 Size, and Student Achievement
研究了学校规模对学生数学成绩的影响，发现少于600人的小规模学校学生成绩显著高于超过800人的大规模学校，为市场导向的学校改革提供了实证依据。
Advocates of market-based public school reform maintain that offering parents and students a choice of schools will promote more effective performance by teachers and administrators. Few proposals have been implemented, however, so empirical evidence of this consequence is scant. This paper examines the effect on student achievement of one possible outcome of a more decentralized educational system-smaller schools. The authors find that students in small schools of fewer than 600 pupils scored much higher on math achievement tests than otherwise comparable students in large schools of more than 800 pupils.
