Questioning Usability of Visual Instructional Design Languages: The Case of CPM

摘要

CPM is a visual instructional design language which provides the designers with a set of concepts allowing to semi formally describe Problem-Based learning scenarios and to document them. CPM is thus a language which is both useful for designers and for developers of Technology-Enhanced Learning systems while implementing all or part of such learning scenarios. This article reports a few lessons that we learned from CPM language; we question CPM usability from different case-studies in the 'real-world' and we draw conclusions that go beyond the scope of CPM language.
