编程类课程实验报告自动生成与批改方案研究
|
摘要
实践教学是高校本科教学工作的一个重要环节,而实验报告通常是实践环节评分的重要组成部分,能够比较直接有效地反映学生对相关理论知识的理解和掌握程度。以编程类实验课程为研究对象,针对实验报告传统提交方式存在的问题,从减少学生工作量,提高教师批改报告效率的角度出发,借鉴市面上众多成熟的技术并结合编程类课程实验任务的独特性,研究设计一种基于GCC编译的实验报告在线自动生成、提交与批改方案。借助该方案,教师可以在线布置实验任务、批改实验报告;学生可以在线制作实验报告;系统依据教师设定的相关参数开放/关闭实验任务,自动使用k-grams算法检测源码的相似度,自动编译执行学生提交的源码,统计分析实验报告的上交和完成情况。测试结果表明,该方案所设计的功能可以在主流浏览器上正常运行,并在较短的时间内对用户请求做出正确的响应。
Practice teaching is an important part of the undergraduate teaching work,while the experiment reports often as the key component of the practice score. How students master and understand of the related knowledge could be effectively reflected by experiment reports. Programming experiment courses have been taken as the research object in this paper. To deal with the existing problems of traditional test report submission,and to reduce students' work,improve the efficiency of correcting reports,a scheme for reports' online automatic submission and marking was designed based on GCC,where some mature technology was included and the unique of programming courses 'experimental tasks was considered. With this scheme,experimental tasks can be arranged and reports can be correcting tested online by teachers while reports can be made online by student. The experimental task would be opened or closed according to the relevant parameters of teachers have set. The k-grams algorithm used automatically for detecting the similarity of code. The code submitted by students would be automatically compiled and the statistical analysis done by the system. Test results have shown that the operations of the scheme can run normally in the mainstream browsers,and the correct response to the user request in a short time.
