WebIntera-Classroom: An Interaction-Aware Virtual Learning Environment for Augmenting Learning Interactions

Interaction is critical for successful teaching and learning in a virtual learning environment (VLE). This paper presents a web-based interaction-aware VLE--WebIntera-classroom--which aims to augment learning interactions by increasing the learner-to-content and learner-to-instructor interactions. We design a ubiquitous interactive interface that integrates a pen-and-paper interface with a web-based whiteboard to promote effective learner-to-content interactions. We develop a learning analytics tool that instantly shows learners' learning interactions, with which instructors can supervise learner-to-instructor interactions. We implement a high-granularity Learning Analytics Engine (hgLAE) to broadcast, record and play a lecture recording. The hgLAE identifies hotspots in a lecture recording and raises students' awareness of the hotspots when they watch the recording. WebIntera-classroom has been deployed in 11 universities in China. The system obtained high satisfaction in the questionnaires (N = 464) and face-to-face interviews (N = 60) conducted with the users from China Jiliang University. We compared the students' performance, respectively, achieved in traditional classroom and in WebIntera-classroom at China Jiliang University during 2012-2013. The result demonstrates that the students could gain performance improvement by using WebIntera-classroom.
