大多数早期的研究发现，封闭的实验室对学生在计算机科学I中的表现或保留没有积极的影响。由于这些研究使用书面测试来评估学生的表现，他们的结果可能受到封闭实验室教授的内容与书面测试评估内容之间不匹配的影响。另一方面，涉及编写和调试程序的在线测试评估了在封闭实验室中教授的知识和技能。因此，我们进行了一项研究，以评估封闭实验室与在线测试相结合时对学生表现和保留的影响。
我们发现，即使是在线测试，封闭的实验室也不会显著影响学生在课程中的总成绩或保留率。另一方面，有封闭实验室甚至可选实验室的学生在他们的在线第一次测试中的成绩明显好于有开放实验室的学生在他们的书面第一次测试中的成绩。尽管在线考试比笔试对学生的压力更大，但封闭实验室帮助学生准备在线考试。封闭实验室与在线测试相结合，有助于显著提高高于平均水平的学生的课程表现。最后，数学SAT成绩与学生在计算机科学I的表现之间存在显著的相关性。
The majority of earlier studies have found no positive effect of closed labs on student performance or retention in Computer Science I. Since these studies used written tests to assess student performance, their results may have been affected by a mismatch between what was taught in closed labs and what was assessed in the written test. On the other hand, online tests that involve writing and debugging programs assess the very knowledge and skills taught in closed labs. So, we conducted a study to evaluate the effect of closed labs on student performance and retention when they are combined with online testing in the course.
We found that even with online testing, closed labs did not significantly affect either the total score of the students in the course or retention in the course. On the other hand, students with closed or even optional labs scored significantly better on their online first test than students with open labs scored on their written first test. Since this is in spite of the fact that online tests are more stressful to students than written tests, closed labs helped students prepare for online tests. Closed labs, when combined with online testing, helped significantly improve the course performance of above-average students. Finally, there was significant and large correlation between Math SAT score and student performance in Computer Science I.
