«Learning Analytics for Large Scale Data»




Alexandra Cristea


Learning Analytics has many definitions, but one of great simplicity and elegance yet clarity is ‘collecting traces that learners leave behind and using those traces to improve learning’ [Eric Duval]. More recently, however, the interest has moved towards ‘big data’, or large scale data, in all aspects of our lives, including for education and learning. This talk will discuss various recent approaches to learning analytics implemented and published by our AIHS research group (Artificial Intelligence and Human Systems) at Durham Computer Science. It will include processing of and analytics based on MOOC data, large-scale questionnaires, private versus public channels of communication in online or blended courses, with applications such as in predicting learner dropout, gamification approaches as well as temporal sentiment analysis, or instructor intervention need.
