Redes sociales y aprendizaje móvil en Educación Física: Creación colaborativa de principios de diseño. Translated Title: Social networks and mobile learning in Physical Education: Creating design principles collaboratively

Physical Education should focus on the development of the student's physical, cognitive, social, and affective domains, using, among others, the potential of active methodologies and the use of technological resources. To this end, there must be design principles that guide the pedagogical?digital strategies to be implemented by teachers in the area. The aim of this study is the creation of these principles through the collaboration of teachers and students through a collaborative intervention project that took place in a real classroom context. The research method corresponds to Design-Based Research, in a three?year iterative process for the design, implementation, and evaluation of this educational intervention. The participating teachers teach 17 groups of Secondary Education at the 4th ESO and 1st Baccalaureate levels (a total of 372 students, 189 girls and 184 boys). The results of this study show a series of design principles for implementing pedagogical-digital strategies. Gamification narratives to guide teaching programming stand out, as well as the use of virtual teaching-learning environments specific to Physical Education that combine content management systems, social networks and physical activity monitoring.
