In the United States, the onset of COVID-19 triggered a nationwide lockdown, which forced many universities to move their primary assessments from invigilated in-person exams to unproctored online exams. This abrupt change occurred midway through the Spring 2020 semester, providing an unprecedented opportunity to investigate whether online exams can provide meaningful assessments of learning relative to in-person exams on a per-student basis. Here, we present data from nearly 2,000 students across 18 courses at a large Midwestern University. Using a meta-analytic approach in which we treated each course as a separate study, we showed that online exams produced scores that highly resembled those from in-person exams at an individual level despite the online exams being unproctored-as demonstrated by a robust correlation between online and in-person exam scores. Moreover, our data showed that cheating was either not widespread or ineffective at boosting scores, and the strong assessment value of online exams was observed regardless of the type of questions asked on the exam, the course level, academic discipline, or class size. We conclude that online exams, even when unproctored, are a viable assessment tool.
在美国,COVID-19 的爆发引发了全国性的封锁,迫使许多大学将主要评估从监考的面对面考试转移到无人监考的在线考试。这种突然的变化发生在 2020 年春季学期的中途,为我们提供了一个前所未有的机会,调查在线考试相对于面对面考试是否可以在每个学生的基础上提供有意义的学习评估。在这里,我们提供了来自中西部一所大型大学的 18 门课程近 2000 名学生的数据。我们采用元分析方法,将每门课程视为一个单独的研究,结果表明,尽管在线考试无人监考,但在线考试的成绩与面对面考试的成绩高度相似,这从在线考试成绩与面对面考试成绩之间的强相关性可以看出。此外,我们的数据表明,作弊要么不普遍,要么不能有效地提高分数,而且无论考试中提出的问题类型、课程水平、学科或班级规模如何,在线考试的强大评估价值都显而易见。我们的结论是,即使是无人监考的在线考试,也是一种可行的评估工具。
