Abstract

Performance on homework questions was compared with performance on related exam questions querying the same fact or principle, was used to assess the effect of answering online homework questions on subsequent exam performance. A distinctive pattern of performance was found for some students in which superior performance on online homework questions resulted in poorer exam performance. When assessed over an eleven-year period, for 2433 students in 12 different college lecture courses, the percent of students who did not benefit from correctly answering homework questions increased from 14% in 2008 to 55% in 2017. During the most recent two years of the study, when students were asked how they did their homework, students who benefitted from homework reported generating their own answers and students who reported copying the answers from another source did not benefit from homework.

摘要

将家庭作业问题的表现与查询相同事实或原理的相关考试问题的表现进行比较，用于评估回答在线家庭作业问题对后续考试成绩的影响。对于一些学生来说，发现了一种独特的表现模式，其中在线作业问题的出色表现导致考试成绩较差。在为期 11 年的评估中，对于 12 门不同的大学讲座课程的 2433 名学生，没有从正确回答家庭作业问题中受益的比例从 2008 年的 14% 增加到 2017 年的 55%。在最近两年的研究中，当学生被问及他们是如何完成家庭作业时，受益于家庭作业的学生报告说自己生成了答案，学生报告从其他来源复制答案的人没有从家庭作业中受益。
