我们进行了一项跨学期的准实验研究,比较了学生在计算机科学入门课程中频繁和不频繁测试方案下的结果。频繁测试(4次测验和4次考试)学期的学生在代码编写问题上的表现比不频繁测试(1次期中考试和1次期末考试)学期高出9.1至13.5个百分点。我们通过调查、采访和教科书行为分析的额外数据来补充这些表现结果。在调查中,学生们报告说,他们更喜欢考试次数较少的考试,但认为频繁考试学期的考试难度较小,压力较小,尽管考试内容相同。在访谈中,学生们主要表示(1)频繁的测试方案鼓励更好的学习习惯(例如,更多的注意力集中在工作上,更少的填鸭式学习),并导致更好的学习,(2)频繁的考试减少了考试焦虑,(3)频繁的考试制度更公平,但这些观点并没有被普遍接受。学生们认为频繁的测试会导致更好的学习习惯,这一点在我们对该课程互动教科书中学生活动的分析中得到了证实。在频繁的测试学期中,学生花更多的时间在课本阅读上,似乎更认真地回答课本问题(即,通过使用提示和蛮力来减少“游戏系统”)。
We conducted an across-semester quasi-experimental study that compared students' outcomes under frequent and infrequent testing regimens in an introductory computer science course. Students in the frequent testing (4 quizzes and 4 exams) semester outperformed the infrequent testing (1 midterm and 1 final exam) semester by 9.1 to 13.5 percentage points on code writing questions.We complement these performance results with additional data from surveys, interviews, and analysis of textbook behavior. In the surveys, students report a preference for the smaller number of exams, but rated the exams in the frequent testing semester to be both less difficult and less stressful, in spite of the exams containing identical content. In the interviews, students predominantly indicated (1) that the frequent testing regimen encourages better study habits (e.g., more attention to work, less cramming) and leads to better learning, (2) that frequent testing reduces test anxiety, and (3) that the frequent testing regimen was more fair, but these opinions were not universally held. The students' impressions that the frequent testing regimen would lead to better study habits is borne out in our analysis of students' activities in the course's interactive textbook. In the frequent testing semester, students spent more time on textbook readings and appeared to answer textbook questions more earnestly (i.e., less "gaming the system'' by using hints and brute force).
