Plagiarism is a common issue in education. Software can detect plagiarism but little is known about prevention.
To identify ways to reduce the incidence of plagiarism in a postgraduate programme.
From 2006, all student assignments were monitored using plagiarism detection software (Turn It In) to produce percentage text matches for each assignment. In 2007, students were advised software was being used, and that plagiarism would result in penalties. In 2008, students attending a key module took part in an additional interactive seminar on plagiarism. A separate cohort of students did not attend the seminar, allowing comparison between attendees and non-attendees.
Between 2006 and 2007, mean percentage text match values were consistent with a stable process, indicating advice and warnings were ineffective. Control chart analysis revealed that between 2007 and 2008, mean percentage text match changes showed a reduced text match in all nine modules, where students attended the interactive seminar, but none where students did not. This indicated that the interactive seminar had an effect. In 2008, there were no occurrences of plagiarism. Improvements were maintained in 2009.
Advice and warnings against plagiarism were ineffective but a subsequent interactive seminar was effective at reducing plagiarism.
抄袭在教育中是一个普遍存在的问题。软件可以检测抄袭，但对于如何预防抄袭却知之甚少。
确定减少研究生课程中抄袭发生率的方法。
自 2006 年起，使用抄袭检测软件（Turnitin）监控所有学生作业，为每个作业生成文本匹配百分比。2007 年，学生们被告知正在使用该软件，抄袭将导致处罚。2008 年，参加一个重要模块的学生参加了一个额外的关于抄袭的互动研讨会。另一组学生没有参加研讨会，允许对与会者和非与会者进行比较。
2006 年至 2007 年间，平均文本匹配百分比值与稳定的过程一致，表明警告和提醒无效。控制图分析表明，2007 年至 2008 年间，所有九个模块中参加互动研讨会的学生的平均文本匹配百分比变化显示文本匹配减少，但没有参加研讨会的学生则没有。这表明互动研讨会有效果。2008 年没有发生抄袭行为。2009 年保持了改进。
防范抄袭的建议和警告无效，但随后的互动研讨会有效地减少了抄袭。
