A service-oriented architecture for real time data collection in e-learning context: SCORM runtime environment case study

Digital tracks represent the information about activities of users during their interactions with a computing platform. In e-learning environments, the analysis of these tracks is considered as an information source of obvious importance: the Effectiveness of the monitoring process of learning depends on it as taking good decisions like the update of the available learning resources and the personalization of the learning path of learners according to their activities and their perpetual changing profiles. In this paper we propose a web service based system for tracks collection. A Service oriented layer for data collecting, based on the standardized CMI data model is introduced. So as to construct a complete data model matching the needs of learning tracking, we suggest defining an extension for the CMI data model adopted by SCORM to take into consideration the activities of communication between different learning actors within the learning management system. Components charged of data preprocessing and transformation are also, but briefly, described. Key-Words: data collection, tracks analysis, SOA, e-learning, SCORM, data model, interactions.
