摘要:

学生知识的准确预测是个性化学习系统的基础。在这里,我们提出了一种新的集成模型来预测学生的知识差距。将我们的方法应用于在线教育平台Duolingo的学生跟踪数据,我们在2018年第二语言习得建模共享任务中的所有三个数据集的两个评估指标上都获得了最高分。我们描述了我们的模型,并讨论了相关的任务相比,它将如何设置在生产环境中的个性化教育。

英文摘要:

Accurate prediction of students knowledge is a fundamental building block of personalized learning systems. Here, we propose a novel ensemble model to predict student knowledge gaps. Applying our approach to student trace data from the online educational platform Duolingo we achieved highest score on both evaluation metrics for all three datasets in the 2018 Shared Task on Second Language Acquisition Modeling. We describe our model and discuss relevance of the task compared to how it would be setup in a production environment for personalized education.
