许多已发表的研究表明,许多在CS1中获得及格成绩的学生可能在CS2中挣扎。这可能会导致CS2的流失率和失败率更高,也许在课程的后续课程中也是如此。许多研究人员已经研究了导致学生成功的因素以及在入门课程中可能出现的常见误解。然而,相对较少的注意力集中在CS1和CS2之间的过渡。在本文中,我们报告了一项研究的各种类型的CS1考试的问题,找到问题,可以预测学生的成功(或缺乏成功)在CS2的目标。结果表明,代码解释和代码完成问题可以特别好的预测,沿着一些代码跟踪问题。我们讨论了一些因素,可能使某些问题比其他问题更好的预测,在这个过程中证实了一些观察,已报告的其他研究人员。这项实验的结果似乎很有希望,并指出了进一步研究的几种可能性。
A number of published studies indicate that many students who receive passing grades in CS1 may struggle in CS2. This can lead to higher attrition and failure rates in CS2, and perhaps also in subsequent courses in the curriculum. Many researchers have studied factors that lead to student success and common misconceptions that may arise in introductory courses. However, relatively little attention has been focused on the transition between CS1 and CS2. In this paper, we report on a study of a variety of types of CS1 exam questions, with the goal of finding questions that can predict a student's success (or lack of success) in CS2. Results indicate that code explanation and code completion questions can be especially good predictors, along with some code tracing questions. We discuss some of the factors that may make certain questions better predictors than others, in the process confirming some observations that have been reported by other researchers. The results from this experiment seem promising, and point to several possibilities for further research.
