A Usability Evaluation of Graphical Modelling Languages for Authoring Adaptive 3D Virtual Learning Environments
Ahmed Ewais, Olga De Troyer · 2014
Adaptive three-dimensional (3D) virtual learning environments offer many advantages for learning. However, developing them is still far from easy and is usually only done by specialized people. One way to support educators in designing adaptive 3D Virtual Learning Environments is the use of domain specific modelling languages as such languages provide a high level of abstraction. In addition, also visual (or graphical) languages are recommended for non-technical users. Although such an approach, visual domain specific modelling languages, seems to be promising, there is a need for evaluation this in practice. Usability and acceptance could become a problem because the authoring process could become relatively complex. This paper reports on a pilot evaluation performed to evaluate the use of visual domain specific modelling languages for designing (i.e. authoring) adaptive 3D virtual learning environments.
