论文摘要
大规模开放在线课程(MOOC)的诞生对教学的交付方式产生了不可否认的影响。似乎传统的班级教学在年轻一代中变得越来越流行,这是想选择他们在何时,何处和以什么速度选择的那一代。因此,许多大学至少部分地在线迈向了他们的课程。但是,在线课程虽然对年轻一代的学习者非常吸引人,但付出了代价。例如,此类课程的辍学率高于传统课程的辍学率,与教师的人相互作用降低会导致教育工作者的及时指导和干预。基于机器学习(ML)的方法在其他领域表现出了惊人的成功。现有的应用基于ML的技术需要大量数据的污名似乎是一种瓶颈,在处理具有有限生产数据的小型课程时。在这项研究中,我们不仅可以很好地利用从在线学习管理系统中收集的数据来预测学生的整体表现,还可以使用它来提出及时的干预策略来提高学生的绩效水平。这项研究的结果表明,在课程的中间,可以提出有效的干预策略,以改变学生的进步进步。我们还根据这项研究的结果提出了一种辅助教学工具,以帮助确定挑战的学生并提出早期干预策略。
The birth of massive open online courses (MOOCs) has had an undeniable effect on how teaching is being delivered. It seems that traditional in class teaching is becoming less popular with the young generation, the generation that wants to choose when, where and at what pace they are learning. As such, many universities are moving towards taking their courses, at least partially, online. However, online courses, although very appealing to the younger generation of learners, come at a cost. For example, the dropout rate of such courses is higher than that of more traditional ones, and the reduced in person interaction with the teachers results in less timely guidance and intervention from the educators. Machine learning (ML) based approaches have shown phenomenal successes in other domains. The existing stigma that applying ML based techniques requires a large amount of data seems to be a bottleneck when dealing with small scale courses with limited amounts of produced data. In this study, we show not only that the data collected from an online learning management system could be well utilized in order to predict students overall performance but also that it could be used to propose timely intervention strategies to boost the students performance level. The results of this study indicate that effective intervention strategies could be suggested as early as the middle of the course to change the course of students progress for the better. We also present an assistive pedagogical tool based on the outcome of this study, to assist in identifying challenging students and in suggesting early intervention strategies.
