2 Source: Bruce McLarenEducational Data Mining Seminar 2007/08 What is Educational Data Mining (EDM)?  Making good use of the raw data collected by e-Learning and educational technology systems  Motivated by:  Proliferation of data from many Internet-based educational systems  Base conclusions and development on real data rather than conjecture and intuition  Use educational data to, for example, improve systems, evaluate student behavior, support teachers  Interactive Learning Environments: intelligent tutoring systems, collaborative systems, open inquiry systems  Scaling up - Possibility for large-scale and longitudinal analysis  How are students learning from and reacting to educational technologies?
