Over recent years, Model-Driven-Engineering has attracted growing interest as much as a research domain as an industrial process that can be applied to various educational domains. This article aims to discuss and propose such an application for learning-scenario-centered instructional design processes. Our proposition is based on a 3-domain categorization for learning scenarios. We also discuss and explain why we think Domain-Specific Modeling techniques are the future new trend in order to support the emergence of communities of practices for scenario-based instructional design. The originality resides in the support we propose to help communities of practitioners in building specific Visual Instructional Design Languages with dedicated editors instead of providing them with yet another language or editor.
