Abstract:

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 and social media platforms. The first study is on a learning analytic tool for visualizing the statistics and timelines of collaborative Wikis built by secondary school students during their group projects in inquiry-based learning. Text categorization is used to detect thinking orders of student writings. The tool is now being evaluated in classrooms of two secondary schools in Hong Kong. The second study is a longitudinal analysis of student interactions on Blogs and Facebook in an experiential learning course across six years. Social network analysis was applied to investigate how student interactions are related to learning outcomes. Student postings were analyzed using association rule mining and text categorization. Implications of the findings on teaching and learning will be discussed.
