Mediaciones tecnológicas: nuevos escenarios de la práctica pedagógica Henry Alfonso Muñoz Rojas Educación Mediación práctica pedagógica tecnologías de la información El objetivo del artículo es dilucidar y reflexionar sobre las dimensiones que se configuran en una transformación de las prácticas pedagógicas y que pueden conducir a la configuración de nuevos escenarios educativos, basados en las mediaciones tecnológicas, entre otros, producto del análisis cualitativo de los referentes conceptuales estudiados en investigaciones que fueron desarrolladas entre los años 2009 y 2013. El artículo está circunscrito en el desarrollo del proyecto titulado ‘Enfoques teóricos de proyectos de investigación en mediaciones de Tecnologías de Información y Comunicación: una configuración para una aproximación conceptual’, producto de la convocatoria N.° 9 de la Vicerrectoría de la Universidad Abierta y a Distancia (VUAD) de la Universidad Santo Tomás. Se indagó sobre el aprendizaje autónomo y colaborativo, el rol del tutor virtual, la presencia social, docente y cognitiva, la inteligencia colectiva y la educación digital, entre otras categorías emergentes. Metodológicamente la disertación se apoyó en la aplicación de Atlas.ti, programa que permitió reforzar los procesos de ordenar y organizar la información originada en diversas fuentes y determinar la categorización y la construcción de mapas semánticos. Finalmente se presentan unas conclusiones e interrogantes sobre perspectivas de la tecnología y la educación. 2016 artículo científico 2216-0159 https://www.redalyc.org/articulo.oa?id=477248173009 https://www.redalyc.org/journal/4772/477248173009/ https://www.redalyc.org/journal/4772/477248173009/html/ https://www.redalyc.org/journal/4772/477248173009/477248173009.epub https://www.redalyc.org/journal/4772/477248173009/movil http://dx.doi.org/10.19053/22160159.4172 es http://www.redalyc.org/revista.oa?id=4772 Praxis & Saber application/pdf Universidad Pedagógica y Tecnológica de Colombia Praxis & Saber (Colombia) Num.13 Vol.7
