Spécification et conception de services d'analyse de l'utilisation d'un environnement informatique pour l’apprentissage humain

Abstract : The research topic of this thesis is a part of the REDIM (model driven re-engineering) research project. It focuses specifically on the analysis of tracks collected during the learning session by a TEL (Technology Enhanced Learning) system in order to provide teachers indicators calculated. In our work environment, UTL (Usage Tracking Language) allows users to define the indicators in a form close to the design patterns. It was designed to response capitalization and reuse questions. However, UTL did not initially have any means to formally specify how to calculate indicators based on tracks collected. In general, design patterns are limited to the description, they cannot be automated. In addition, textual descriptions in UTL to produce indicators from tracks do not allow generating automatically an indicator’s values.Our main research objective was therefore to define models, methods and tools for formalizing and automating the calculation of indicators. We propose an extension for UTL named DCL4UTL (Data Combination Language for UTL) to model indicators in a capitalizable, automatable and reusable form to provide meaningful indicators to teachers/designers. With this new version, the indicators can be calculated in real-time or after a learning session in the context of tutoring actions or the reengineering of learning scenarios, respectively.The originality of our approach (DCL4UTL) lies in the fact that this version not only capitalize know-how on analysis techniques of the use an TEL system, but also (1) formally describe models and calculation methods of indicators from tracks collected by a TEL system, (2) integrate external functions (from other analysis tools), and (3) create parameterized intermediate data facilitating the modeling and reuse of indicators’ calculation method. We have also developed an analysis tool to calculate modeled indicators. Our approach and language have been validated by several experiments with several existent TEL systems.
