Authoring tools in Intelligent Tutoring Systems (ITS) are designed to make it easier for tutors the use of Artificial Intelligence tools. Authoring tools allow tutors to develop adaptive, learner-centered courses that promote interaction between students and virtual tutors. This article presents a review of Virtual Reality (VR) tools for the creation of Virtual Learning Environments (VLE). In particular, we provide an analysis regarding how this kind of tools can be combined with authoring tools in ITS to achieve VLE that present to students realistic, interactive and immersive educational content. Finally, we discuss some challenges and opportunities in the design and implementation of authoring tools and tools of VR for the generation of VLE.

In this paper we present a Web platform designed to allow medical students and practitioners to study clinical cases on their own. The main objective of this proposal is to address key problems inherent in the traditional study of clinical cases by providing a tool that implements techniques and elements of gamification, simulation, and serious games. The proposed platform offers an improved learning experience through a virtual environment that provides an alternative method for training and interpretation of clinical cases for medical examinations. Medical students and practitioners can play the role of a real doctor in a simulated office. In particular, the platform allows medical students and practitioners to learn through their mistakes without hurting human beings. In addition, this platform is designed to allow users to add new clinical cases and make them available for study. The platform was validated in a local hospital by 8 medical practitioners. The participants indicated that the platform design, the tutorials included, and the ease of use factors are satisfactory.
