对于数学能力落后于预期的学生,公立学校通常会增加一天中用于数学教学的部分时间。通过对中学生的研究,并使用回归不连续的方法,我估计了要求两节数学课--一节补习课,一节常规课--而不是只要求一节课的因果关系。在0.16-0.18学生标准差的要求下,数学成绩增长得更快。然而,在回到常规的单节课时间表一年后,最初的收益衰减了多达一半,两年后,最初的治疗效果仅保留了三分之一。随着时间的推移,这种影响逐渐减弱的模式反映了其他教育干预措施--分配给更熟练的老师,减少班级规模,留住学生--但在数学上花费更多时间会带来不同的成本。一个值得注意的成本是,更多的数学时间排挤了其他学科的教学。
For students whose math skills lag expectations, public schools often increase the fraction of the school day spent on math instruction. Studying middle-school students and using regression discontinuity methods, I estimate the causal effect of requiring two math classes—one remedial, one regular—instead of just one class. Math achievement grows much faster under the requirement, 0.16–0.18 student standard deviations. Yet, one year after returning to a regular one-class schedule, the initial gains decay by as much as half, and two years later just one-third of the initial treatment effect remains. This pattern of decaying effects over time mirrors other educational interventions—assignment to a more skilled teacher, reducing class size, retaining students—but spending more time on math carries different costs. One cost is notable, more time in math crowds out instruction in other subjects.
