A common need in system, software, and hardware engineering is to describe system architectures, especially in demanding domains such as aeronautics, defence or telecommunications. Kitalpha is an environment to develop and execute MBE (Model-Based Engineering) workbenches for description of system architecture. Kitalpha uses the DSL technique in order to develop such development environments accurately, quickly, and safely. This paper presents the main features of Kitalpha and lessons learned from a DSL-based development.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
