¿Son conscientes las universidades de los cambios que se están produciendo en la Educación Superior? Francisco José García-Peñalvo Educación MOOC MOOC Universidad Universidad Formación virtual El editorial de este último número del volumen 17, correspondiente al año 2016, reflexiona sobre los cambios vertiginosos que se están dando en torno a la educación superior, con modelos de gestión y negocio basados en la virtualización de la formación y en una orientación hacia el mercado laboral, que ponen en entredicho el concepto tradicional de Universidad. La pregunta que subyace es si la Universidad, como institución, es consciente de todos estos movimientos y está preparada para dar una respuesta contundente que le permita adaptarse a las nuevas realidades de una Sociedad Digital, sin perder su hegemonía como garante universal de la generación y transmisión del conocimiento científico y humanístico; o, al contrario, fiel a su tradición más conservadora, continúa reforzando el andamiaje de su torre de marfil, alejándose más y más de esta realidad, segura de una posición de privilegio social que entiende inamovible. 2016 editorial 1138-9737 https://www.redalyc.org/articulo.oa?id=201078852001 es http://www.redalyc.org/revista.oa?id=2010 Teoría de la Educación.
