Do Students Go to Class? Should They?
通过定量证据考察大学生缺课的程度及其对学习的影响，并对是否应干预缺课问题提出思考，适合关注教学效果的教育工作者阅读。
Lectures and other class meetings are a primary means of instruction in almost all undergraduate courses. Yet almost everyone who has taught an undergraduate course has probably noticed that attendance at these meetings is far from perfect. There is surprisingly little systematic evidence, however, about attendance and its effects. There are three natural questions: What is the extent of absenteeism? How much, if at all, does absenteeism affect learning? Should anything be done about absenteeism? This article presents quantitative evidence on the first two of these questions and speculative comments on the third.
