| 摘 要: 随着高等教育从知识传授到能力培养的转型，实践教学成为大学教师普遍重视的人才培养环节。实践教 学的主要难点在于教学过程的管控和形成性考核的质量。作业查重系统是降低教师负担，提高过程监控质量的有效工 具。研发了一种便捷、低成本且无须数据库的作业查重系统，采用k-gram字符串匹配算法，逐字符的对比作业文档之 间的字符串，当文档间相同的字符串长度达到阈值时，则计入重复度中。在软件工程课程的教学实践中的应用结果表 明，教师可结合系统查重结果，对教学情况进行分析，从而实现差异化作业质量监控，提高课程质量、促进学风建设。 |

| Abstract: With increasingly extensive attention of college teachers,practice teaching has become the key factor for talent cultivation,because the higher education transition from imparting knowledge to cultivating ability.The main difficulty in practice teaching lies in the management of practice teaching process and the quality of formative assessment. Assignment duplicate-checking system is effective in reducing the burden on teachers and improving the quality of process monitoring.Therefore,adopting k-gram matching algorithm to compare the character strings between assignment files,the paper proposes a convenient,low-cost and database-free assignment duplicate-checking system.When certain same character string in two files reaches the threshold value,it is counted into duplicate calculation.Practice has proven that teachers can combine the obtained results and analyze the teaching situation,thus achieving high-efficiency teaching by human-computer cooperation,which is conducive to encouraging students to innovate,improving the quality of course teaching and promoting the construction of study style. |
