题目：Towards learning analytics based on cognitive modeling
报告摘要：The wide use of computer aided educational settings boosts the research in educational data mining and learning analytics. In this talk we are going to report our recent studies on deep learning analytics based on cognitive modelling. We propose a fuzzy cognitive diagnosis model to mine the specific skill proficiency of the examinees based on their performance of objective and subjective problem. We design a Bayesian network based method to detect “slip & guess” from examinees’ responses with the obtained skill proficiency. We study the gaming-the-system behaviour in intelligent tutoring systems and develop a framework that models student learning by combining the knowledge and gaming factor based on multiple-attempt responses.
