摘要:

本研究的重点是使用教育数据采掘(EDM)技术进行定量分析的学生互动的电子学习系统,通过教师主导的非分级和分级课程。这项工作有助于为他们制定一系列在线短期课程的指导方针。本研究以412名学生为研究对象,分析其在数位学习系统中的存取行为,并依据其课程存取记录,以K-均值分群法进行分群。结果表明,在分级和非分级学习环境中,超过40%的学生是被动的在线学习者。结果表明,学习环境的差异会改变学生群体的在线访问行为。聚类将学生群体根据他们的课程访问行为分为五个访问组。在这些组中,最少访问组(NG-41%和G-42%)和最高访问组(NG-9%和G-5%)可以非常清楚地识别,因为它们的访问与其余组不同。

英文摘要:

The focus of this research was to use Educational Data Mining (EDM) techniques to conduct a quantitative analysis of students interaction with an e-learning system through instructor-led non-graded and graded courses. This exercise is useful for establishing a guideline for a series of online short courses for them. A group of 412 students' access behaviour in an e-learning system were analysed and they were grouped into clusters using K-Means clustering method according to their course access log records. The results explained that more than 40% from the student group are passive online learners in both graded and non-graded learning environments. The result showed that the difference in the learning environments could change the online access behaviour of a student group. Clustering divided the student population into five access groups based on their course access behaviour. Among these groups, the least access group (NG-41% and G-42%) and the highest access group (NG-9% and G-5%) could be identified very clearly due to their access variation from the rest of the groups.
