Learning analytics is an emerging and fast growing multidisciplinary field in which data about learners and their contexts are analyzed for understanding and optimizing learning and learning environments. This seminar will discuss two recent and ongoing studies in learning analytics. The first study is on automated analysis of student comments on Wikis of group writing projects. Association rule mining and text categorization are applied to analyze and automatically classify student comments into categories in social interaction, thinking process and thinking development. The second study is to predict student performance based on system logs in Learning Management Systems (LMS). Linear regression with feature selection is used to build prediction models. A framework is proposed to link LMS logs, assessment tasks and learning outcomes. The goal is to design and develop a tool for instructors and students to monitor learning progress in real-time.
