标题：From Project Based Collaborative Learning (PBCL) Scenario Elaboration toward PBCL Scenario Able to be Implemented in a Target Platform: PBCL Scenario Transformation Tool
摘要：In the context of Technology Enhanced Learning System (TELS) engineering, a Project Based Collaborative Learning Scenario Transformation Tool (PBCL-STT) is proposed. It allows instructors implementing Project Based Collaborative Learning (PBCL) scenarios in a chosen target Learning Management System (LMS) or in an Internet-enabled system for use in projects. This proposal is situated in the framework of an overall strategy consisting firstly, in providing instructors, with a PBCL meta-model to be used in their PBCL scenarios built up. Secondly, it consists in providing them with a model of functionalities dedicated to PBCL. This functionalities model will help them choosing a LMS or an Internet-enabled system for use in projects the most suitable to their PBCL scenarios. Finally, it will provide instructors a Project Based Collaborative Learning Scenario Transformation Tool (PBCL-STT) that transforms their PBCL scenarios into PBCL scenarios able to be implemented in their chosen platform. This paper explains the computer architecture of this transformation tool, which adopts a Model Driven Architecture (MDA) approach. Especially, it explains the elaboration of transformation rules between the PBCL meta-model and that of the chosen platform. A comparison between a PBCL scenario transformed into a PBCL scenario able to be implemented in Moodle platform from one side, and into a PBCL scenario able to be implemented in phpCollab platform from the other side, is established. The objective of this comparison consists in measuring correspondence and semantic losses in each transformation.
