面向学习者个性化学习特征的知识追踪
Knowledge tracing for personalized learning features of learners
摘要
Abstract
Since the existing knowledge tracing models are incapable to adequately model personalized learning characteristics of learners,a knowledge tracing model oriented towards personalized learning characteristics is proposed.Initially,a multi-dimensional question representation system is constructed based on learners'interaction records.Following this,a personalized modeling of learning benefits is achieved by analyzing learners'personalized characteristics and their knowledge gaps.Additionally,a forgetting gate is designed to dynamically adjust the degree of forgetting of knowledge because of the knowledge forgetting during the process of learning.Finally,the learners'knowledge states are updated by integrating learning benefits and knowledge forgetting,and this state is used to predict learners'future performance in answering questions.Experimental results on two public online educational datasets,named ASSISTments2012 and ASSISTments2017,show that the proposed model achieves better predictive performance and can model learners'knowledge states more effectively in comparison with the existing mainstream models.关键词
