A Data Model to Ease Analysis and Mining of Educational Data

Learning software is not designed for data analysis and mining. Because usage data is not stored in a systematic way, its thorough analysis requires long and tedious preprocessing. In this contribution we first present a data model to structure data stored by Learning Management Systems (LMS). Then we give an overview of the system architecture that performs the structure/ export functionality and of its implementation for the Moodle LMS. Finally, we show first results using this data model for analysing usage data.
