Educational Data Mining and Learning Analytics


Educational Data Mining (EDM) and Learning Analytics (LA) are emerging fields of study in learning technology. EDM and LA seek to identify the patterns in the characteristics of learners recorded in a large-scale educational data (e.g., students’ use of interactive learning environment, computer-supported collaborative learning or administrative data from schools). Using the identified patterns, EDM and LA try to better understand students, their learning outcomes, and the learning environment. Learning Technologies faculty, such as Dr. Youngjin Lee, applied various EDM and LA algorithms and techniques, (e.g., Self-Organizing Map (SOM), TrueSkill, Item Response Theory (IRT), Least Absolute Shrinkage and Selection Operator (LASSO), Support Vector Machine (SVM), etc.), to clickstream log files capturing how students enrolled in MOOCs interact with various learning resources in order to identify learning behaviors of students that predict their learning performance and academic success.
