Virtual Reality (VR) is an interesting technology in the context of learning especially for learners with learning disabilities. The design of virtual learning environments (VLEs) is a complex task due to the interdisciplinarity intrinsic to VR and its cognitive aspects. This research work identifies some limitations with existing solutions and studies the design and operationalization of learning situations in the form of scenario models. It takes place in the context of LUSI (Learning Units for School Inclusion) classes and involves a specific learning situation of acquisition of orientation skills. We propose a solution based on virtual reality technology to enhance traditional learning and provide trainers with an educational toolkit, thus allowing them to recreate virtual reality scenarios and assess the learners' progress for learning orientation skills.
