A Learning Environment for Object-Oriented Modeling, Supporting Metacognitive Regulations

This paper describes Diagram, a learning environment for UML object-oriented modeling. Diagram supports the learnerpsilas metacognitive activity through two components: a specific interaction framework and a contextual help system. The interaction framework relies on a three steps organization of the task and original graphical modeling tools. Contextual helps facilitate the control and the correction of their diagram by learners. Two experiments of Diagram, carried out in an ecological context, are presented, and the results are discussed.
