The majority of European, as well as many other, countries responded to the outbreak of the new coronavirus with a closure of schools and universities. The expectation of policy makers was that schools and universities would continue to provide lessons online and that students would engage in home learning. How much home learning has there been? We use nationally representative, longitudinal data on 14- to 25-year-old Swiss students to analyze the effects of school closures on studying time. Our results show that students reduced, on average, their studying time from 35 to 23 hours per week. This reduction was stronger for students in secondary school age than for students older than 18. Contrary to our expectations, these reductions in studying time did not vary between male and female students. In addition, children from families with highly educated parents reduced their studying time in absolute terms more than children from families with low educated parents. In relative terms, reductions in children’s studying time did not vary by parental education. We also found some variation in the reduction in studying time across the three linguistic regions in Switzerland. Taken together, our findings show that studying time was considerably reduced during the closure of schools. We therefore conclude by suggesting political measures that can compensate for the loss in studying time a generation of Swiss students experienced between March and July 2020.

大多数欧洲国家以及许多其他国家通过关闭学校和大学来应对新型冠状病毒的爆发。政策制定者的期望是，学校和大学将继续提供在线课程，学生将参与家庭学习。有多少家庭学习？我们使用 14 至 25 岁瑞士学生的具有全国代表性的纵向数据来分析学校停课对学习时间的影响。我们的结果表明，学生平均每周的学习时间从 35 小时减少到 23 小时。与 18 岁以上的学生相比，中学年龄学生的这种减少幅度更大。与我们的预期相反，这些学习时间的减少在男女学生之间没有差异。此外，父母受教育程度高的家庭的孩子比父母受教育程度低的家庭的孩子减少学习时间的绝对值更多。相对而言，儿童学习时间的减少并没有因父母的教育而改变。我们还发现瑞士三个语言区的学习时间减少情况有所不同。综上所述，我们的研究结果表明，在学校停课期间，学习时间大大减少。因此，我们最后建议采取政治措施，以弥补一代瑞士学生在 2020 年 3 月至 2020 年 7 月期间所经历的学习时间损失。儿童学习时间的减少并没有因父母的教育而改变。我们还发现瑞士三个语言区的学习时间减少情况有所不同。综上所述，我们的研究结果表明，在学校停课期间，学习时间大大减少。因此，我们最后建议采取政治措施，以弥补一代瑞士学生在 2020 年 3 月至 2020 年 7 月期间所经历的学习时间损失。儿童学习时间的减少并没有因父母的教育而改变。我们还发现瑞士三个语言区的学习时间减少情况有所不同。综上所述，我们的研究结果表明，在学校停课期间，学习时间大大减少。因此，我们最后建议采取政治措施，以弥补一代瑞士学生在 2020 年 3 月至 2020 年 7 月期间所经历的学习时间损失。
