越来越多的大学提供在线和混合形式的课程。在线评估的一个挑战是维护学术诚信。我们提出了一个全面的统计分析，以揭示学生的表现差异时，在线考试是在一个监考的环境（即，在课堂上）与无监督的环境（即，场外）。控制学生平均成绩（GPA），没有显着差异，平均整体课程表现或考试成绩两组之间，也没有发现任何差异，在平均向量的个人考试成绩。该研究表明，在无监督环境中参加在线考试的小组在表现结果上有更大的差异。在检查更大的变化的潜在原因，进行分析，以评估是否可以观察到的可能的作弊行为的水平增加，从表现结果的学生在unproctored部分。没有发现作弊行为的证据。
Increasing numbers of universities are offering courses in online and hybrid formats. One challenge in online assessment is the maintenance of academic integrity. We present a thorough statistical analysis to uncover differences in student performance when online exams are administered in a proctored environment (i.e., in class) versus an unproctored environment (i.e., offsite). Controlling for student grade point average (GPA), no significant differences in mean overall course performance or exam performance between the two groups were found, nor were there any differences in the mean vectors of individual exam scores. The study reveals that the group taking online exams in the unproctored environment has significantly more variation in their performance results. In examining potential causes of the greater variation, analyses were performed to assess whether an increased level of possible cheating behavior could be observed from performance results for students in the unproctored section. No evidence of cheating behavior was found.
