Until very recently, we considered Virtual Reality as something that was very close, but it was still science fiction. However, today Virtual Reality is being integrated into many different areas of our lives, from videogames to different industrial use cases and, of course, it is starting to be used in medicine. There are two great general classifications for Virtual Reality. Firstly, we find a Virtual Reality in which we visualize a world completely created by computer, three-dimensional and where we can appreciate that the world we are visualizing is not real, at least for the moment as rendered images are improving very fast. Secondly, there is a Virtual Reality that basically consists of a reflection of our reality. This type of Virtual Reality is created using spherical or 360 images and videos, so we lose three-dimensional visualization capacity (until the 3D cameras are more developed), but on the other hand we gain in terms of realism in the images. We could also mention a third classification that merges the previous two, where virtual elements created by computer coexist with 360 images and videos. In this article we will show two systems that we have developed where each of them can be framed within one of the previous classifications, identifying the technologies used for their implementation as well as the advantages of each one. We will also analize how these systems can improve the current methodologies used for medical training. The implications of these developments as tools for teaching, learning and training are discussed.

a b s t r a c tTraditionally, mobile learning has been more strongly developed within the field of informal education. However, in the past few years there has been a growing interest for the integration of these technologies in the formal education field. Among the key elements needed to successfully achieve this integration process is the acceptance of mobile technologies by the teaching body.In this paper we propose to identify the determining constructs that explain the teachers' intention of using mobile technologies. To this end we have designed a research model based on the Technology Acceptance Model (TAM), expanded with constructs from other theories. The resulting model was subjected to a content validation process performed by a committee of experts.Lastly, we selected nine constructs for the development of the research model and we formulated 13 hypotheses that describe the relationships among them. Further studies on the research model to extend its validity and reliability are suggested.

La pandemia mundial de la COVID-19 ha llevado a la suspensión de la actividad docente en muchos países. En el ámbito universitario la transformación urgente de las clases presenciales a un formato online se ha llevado a cabo de una forma que se puede calificar como aceptable en términos generales, si bien las medidas tomadas se han ajustado a la urgencia y no a una planificación pensada a priori para impartir una asignatura con una metodología completamente online. Afrontar una evaluación online masiva es algo a lo que las universidades de corte presencial no se habían enfrentado nunca desde una perspectiva institucional. El profesorado y el estudiantado, por tanto, tienen que colaborar para dar una respuesta que integre decisiones metodológicas y tecnológicas, a la vez que garantice la equidad, la seguridad jurídica y la transparencia para todos los actores, internos y externos. El Grupo de Responsables de Docencia Online de las Universidades Públicas de Castilla y León ha elaborado una guía de recomendaciones para ayudar al profesorado y a las universidades en este proceso. La esencia de esta guía se presenta en este artículo para hacer llegar estas recomendaciones al gran número de docentes que comparten este problema en este momento excepcional en todo el planeta.
