学习分析中上下文数据采掘的多源关系

Multi-source Relations for Contextual Data Mining in Learning Analytics

Julie Bu Daher, Armelle Brun, Anne Boyer

摘要:

学习分析(LA)的目标是多方面的,其中帮助学生了解他们的学业进展和改善他们的学习过程,这是我们工作的核心。为了实现这一目标,LA依赖于教育数据:学生在VLE上的活动轨迹,或学术,社会人口信息,有关教师,教学资源,课程等的信息。数据采掘,特别是模式挖掘,旨在从大型数据集中提取有价值的和可理解的信息。在我们的工作中,我们假设多个教育数据源形成了一个丰富的数据集,可以产生有价值的模式。因此,挖掘这些数据是达到帮助学生目标的一种有希望的方法。然而,数据内的异质性和相互依赖性导致高计算复杂性。因此,我们的目标是设计低复杂度的模式挖掘算法,挖掘多源数据,考虑到依赖性和异构性的来源。形成的模式是有意义的和可解释的,因此,他们可以直接用于学生。

英文摘要:

The goals of Learning Analytics (LA) are manifold, among which helping students to understand their academic progress and improving their learning process, which are at the core of our work. To reach this goal, LA relies on educational data: students' traces of activities on VLE, or academic, socio-demographic information, information about teachers, pedagogical resources, curricula, etc. The data sources that contain such information are multiple and diverse. Data mining, specifically pattern mining, aims at extracting valuable and understandable information from large datasets. In our work, we assume that multiple educational data sources form a rich dataset that can result in valuable patterns. Mining such data is thus a promising way to reach the goal of helping students. However, heterogeneity and interdependency within data lead to high computational complexity. We thus aim at designing low complex pattern mining algorithms that mine multi-source data, taking into consideration the dependency and heterogeneity among sources. The patterns formed are meaningful and interpretable, they can thus be directly used for students.
