增加在校教学时间是许多政府试图改善学生学习的核心要素，但之前的研究--主要基于观察数据--对这种方法的效果提出了异议，并指出了对学生行为的潜在负面影响。基于一项大规模的整群随机试验，我们发现，增加教学时间会增加学生的学习，一般增加教学时间至少与专家开发的详细教学程序在相同的时间内增加教学时间一样有效。这些发现支持了增加教学时间的价值。
Increasing instruction time in school is a central element in the attempts of many governments to improve student learning, but prior research-mainly based on observational data-disputes the effect of this approach and points out the potential negative effects on student behavior. Based on a large-scale, cluster-randomized trial, we find that increasing instruction time increases student learning and that a general increase in instruction time is at least as efficient as an expert-developed, detailed teaching program that increases instruction with the same amount of time. These findings support the value of increased instruction time.
