十多年前,大型研究型大学为没有编程经验的学生开设的 CS1 课程经过重新设计,纳入了编程教学中的三种最佳实践:媒体计算、结对编程和同伴指导。此次修订的目的是提高课程质量,吸引更多的学生群体,并提高专业的保留率。对课程的初步分析表明,该专业学生的通过率和一年保留率有所提高。现在时间已经过去,那些受修订影响的学生已经有时间毕业了,这项纵向研究通过检查十二年期间(2001 年至 2013 年)学生的成绩,重新审视并扩展了这些先前的发现。检查的学生成绩包括 CS1 的不及格率、专业的保留率、转专业的率、获得学位的时间以及后续专业课程的表现。我们将这些发现与同一机构的另一门 CS1 课程收集的类似指标进行比较,该课程迎合具有编程经验的学生,并且在同一时间段内没有进行更改。总体而言,纳入媒体计算、结对编程和同伴指导意味着 CS1 的通过率以及从 CS1 到毕业的专业保留率的显着提高。反过来,没有迹象表明这一较大群体的学生在高年级课程的较低成绩或攻读学位的时间方面受到任何伤害。
Over a decade ago, the CS1 course for students without prior programming experience at a large research-intensive university was redesigned to incorporate three best practices in teaching programming: Media Computation, Pair Programming, and Peer Instruction. The purpose of this revision was to improve the quality of the course, appeal to a larger student body, and improve retention in the major. An initial analysis of the course indicated an increase in pass rates and 1-yr retention of students in the major. Now that time has passed and those students impacted by the revision have had time to graduate, this longitudinal study revisits and expands on these prior findings through examining student outcomes over a twelve year period (2001 through 2013). The student outcomes examined include failure rates in CS1, retention rates in the major, rates of switching into the major, time to degree, and performance in subsequent major courses. We compare these findings against similar metrics collected for another CS1 course at the same institution that caters to students with prior programming experience and did not make changes during this same time period. Overall, the inclusion of media computation, pair programming, and peer instruction corresponds to a significant improvement in passing rates for CS1 as well as retention of majors from CS1 through graduation. In turn, there is no indication that this larger group of students experienced any harm in terms of lower grades in upper-division courses or their time to degree.
