Virtual Reality (VR) is gaining in popularity and its added value for learning is being recognized. However, its richness in representation and manipulation possibilities may also become one of its weaknesses, as some learners may be overwhelmed and be easily lost in a virtual world. Therefore, being able to dynamically adapt the virtual world to the personal preferences, knowledge, skills and competences, learning goals and the personal or social context of the learning becomes important. In this paper, we describe how an adaptive Web-based learning environment can be extended from a technological point of view to support VR.
