What do you do when a change in enrollment policies leaves you with more than 600 students in a first-term university calculus class, three-quarters of those students had a failing mark in mathematics in the pre-enrollment test, you planned a series of remedial activities for the second term, and the COVID-19 pandemic shuts the university down with a two-day notice? The pandemic hit instruction with might, forcing schools and universities that were timidly experimenting with digital tools to reinvent themselves in days. The pandemic also offered incentives for creative solutions that, in normal times, would have been considered fit for submission to the committee for recursive committee submissions at best. This paper narrates a teaching experience of how we proposed and managed an at-distance remedial course in August that not only catered to more than twice the number of students expected by our best forecasts, but was a very good success once its effectiveness was compared to the outcomes predicted by the pre-enrollment test scores. We expose the design of the course and link its measured effectiveness with both its design and student engagement; in particular, we show that a different approach to the examination of cognitive load and to fostering student–teacher and student–student communication thanks to digital mediation could be effective in countermanding the math-induced drop-out phenomenon in STEM.

应对大流行：微积分远程辅导暑期课程

当招生政策的变化让你在第一学期的大学微积分课上有 600 多名学生，其中四分之三的学生在入学前考试中数学不及格时，你会怎么做，你计划了一系列第二学期的补习活动，而 COVID-19 大流行提前两天通知大学关闭？大流行对教学产生了强大的打击，迫使那些胆怯地尝试使用数字工具的学校和大学在几天内重塑自我。大流行还为创造性的解决方案提供了激励，在正常情况下，这些解决方案最多被认为适合提交给委员会以供递归委员会提交。本文讲述了我们如何在 8 月份提出和管理远程辅导课程的教学经验，该课程不仅迎合了我们最佳预测所期望的学生人数的两倍多，而且一旦将其有效性进行了比较，就取得了非常好的成功。入学前考试成绩预测的结果。我们公开课程的设计，并将其衡量的有效性与其设计和学生参与联系起来；特别是，我们展示了一种不同的方法来检查认知负荷，并通过数字中介促进学生-教师和学生-学生之间的交流，可以有效地遏制 STEM 中由数学引起的辍学现象。但是一旦将其有效性与入学前测试分数预测的结果进行比较，就取得了非常好的成功。我们公开课程的设计，并将其衡量的有效性与其设计和学生参与联系起来；特别是，我们表明，由于数字中介，采用不同的方法来检查认知负荷并促进学生-教师和学生-学生之间的交流，可以有效地遏制 STEM 中由数学引起的辍学现象。但是一旦将其有效性与入学前测试分数预测的结果进行比较，就取得了非常好的成功。我们公开课程的设计，并将其衡量的有效性与其设计和学生参与联系起来；特别是，我们表明，由于数字中介，采用不同的方法来检查认知负荷并促进学生-教师和学生-学生之间的交流，可以有效地遏制 STEM 中由数学引起的辍学现象。
