E-learning is achieved by the deep integration of modern education and information technology, and plays an important role in promoting educational equity. With the continuous expansion of user groups and application areas, it has become increasingly important to effectively ensure the quality of e-learning. Currently, one of the methods to ensure the quality of e-learning is to use mutually independent e-learning behaviour data to build a learning performance predictor to achieve real-time supervision and feedback during the learning process. However, this method ignores the inherent correlation between e-learning behaviours. Therefore, we propose the behaviour classification-based e-learning performance (BCEP) prediction framework, which selects the features of e-learning behaviours, uses feature fusion with behaviour data according to the behaviour classification model to obtain the category feature values of each type of behaviour, and finally builds a learning performance predictor based on machine learning. In addition, because existing e-learning behaviour classification methods do not fully consider the process of learning, we also propose an online behaviour classification model based on the e-learning process called the process-behaviour classification (PBC) model. Experimental results with the Open University Learning Analytics Dataset (OULAD) show that the learning performance predictor based on the BCEP prediction framework has a good prediction effect, and the performance of the PBC model in learning performance prediction is better than traditional classification methods. We construct an e-learning performance predictor from a new perspective and provide a new solution for the quantitative evaluation of e-learning classification methods.
电子学习是现代教育与信息技术深度融合的产物,对促进教育公平起着重要作用。随着用户群体和应用领域的不断扩大,有效保障电子学习质量变得越来越重要。目前,保障电子学习质量的方法之一是使用相互独立的电子学习行为数据来构建学习绩效预测器,以在学习过程中实现实时监督和反馈。然而,这种方法忽略了电子学习行为之间的固有相关性。因此,我们提出了基于行为分类的电子学习绩效(BCEP)预测框架,该框架选择电子学习行为的特征,根据行为分类模型使用特征与行为数据融合,以获得每种行为的类别特征值,最后基于机器学习构建学习绩效预测器。此外,由于现有的电子学习行为分类方法没有充分考虑学习过程,我们还提出了一种基于电子学习过程的在线行为分类模型,称为过程-行为分类(PBC)模型。使用开放大学学习分析数据集(OULAD)进行的实验结果表明,基于 BCEP 预测框架的学习性能预测器具有良好的预测效果,PBC 模型在学习性能预测方面的性能优于传统分类方法。我们从新的角度构建了电子学习性能预测器,为电子学习分类方法的定量评估提供了新的解决方案。
