This poster will describe the Learner Interaction Monitoring System (LiMS), designed to capture data demonstrating learner online engagement with course materials. The poster presentation will explain how the LiMS ‘event capture model’ collects detailed real-time data on learner behavior in self- directed online learning environments, and interprets these data by drawing on behavioral research. We believe that LiMS offers education and training managers in corporate contexts a valuable tool for the evaluation of learner performance and course design. By permitting more detailed demonstration of ROI in education and training, LiMS allows managers to make the case for web based courseware that reflects appropriate and evidence-based instructional design, rather than budgetary constraints.
