一句话:报告将软件工程课程评分从功能完成度转向技术运用,发现可提升弱生成绩并降低退课率,但课程评价下降。
传统软件工程课程按截止日期前完成的功能或任务评分,导致部分学生级联失败和“功能取巧”。作者在一门 Web 应用开发课程中把评分改为评价学生所应用的技术。分析使用前四年与改后三年的学生总体表现、笔试成绩、该课程改前两年与改后两年的项目评分以及学生反馈。结果显示:改后弱学生的考试成绩和后续表现提升,退课率下降,但课程反馈得分降低;文本反馈表明新评分方案能更好地教授敏捷 Web 开发最佳实践。
Student projects in software engineering courses are traditionally graded according to the features developed/tasks completed by given deadline. This leads to two problems: cascading failure of some students in the course, and "feature hacking" by the students. In order to address these issues, we decided to shift grading to grading applied techniques in a web application development course. In this paper, we present the analysis of the impacts of our decision. For the analysis we use general student performance data from four prior years and three post-shift years, their performance in written exam, project grades in the web application development course for four years (two prior and two post change), and student feedback to the course. The results show that the shift to grading technique use has resulted in improved student exam and future performance among weaker students, reduced drop-out rates, and lowered the student feedback score for the course. The added benefit according to textual feedback from students was that the new grading scheme teaches students the best practices of agile web development better than previously possible.
