A Transversal Analysis of Different Learning Design Approaches

The goal of the ICALT workshop "Comparing Educational Modelling* Languages on a Case Study" was to compare different Learning Design approaches. Various teams were asked to design and implement a common case study and to answer common given challenges. Then, a special issue on "Comparing Educational Modelling Languages on the "Planet Game Case Study"" was proposed to give the workshop challengers the opportunity to describe their solution in more detail. It is now time to make the comparison. Based on an in-depth analysis and many exchanges with the teams involved, this paper introduces the approaches and highlights current challenges in the Learning Design field in connection with the pitfalls included in the case study and the given challenges.Editors: Laurence Vignollet (Université de Savoie, France).
