Usability study of TEL recommender system and e-assessment tools united

Abstract

The following article presents a usability study applied over a process in formal learning that involves a set of e-assessment tools for: selfassessment, peer-assessment and summative assessment and then a simulated Recommender System (RS) in Technology Enhanced Learning (TEL). The system is constructed using Web 2.0 technologies and the Learning Management System Moodle. First, the assessment tools collect outcomes which are saved and classified according to European Qualification Framework. Second, in several times of a course, the outcomes are analyzed to find out the competence gaps of learners, the smart indicators of this analysis are showed to the learners. Finally, the simulated recommender system produces suggestions about reinforced resources to each learner according to their competence gaps. The essence of the planned presentation has three main goals: 1. To show the results of usability study on prototypes of assessment tools and the simulated RS in formal learning 2. To provide an idea of user-centered possible responses of RS for Adaptive Educational Hypermedia Systems, 3. To offer an environment for testing new recommendation approaches and methods for researchers. © 2011 Springer-Verlag.
