La profesionalización docente en la modalidad online y la implementación de REI's: aciertos y desafíos

Teaching professionalization in online mode has become a training opportunity for in-service mathematics teachers. The Educational Mathematics Program of the National Polytechnic Institute of Mexico was founded in 2000 and since then has offered a training device to teachers from various regions of Mexico and Latin America. One of the main objectives of this program is to make available to teachers theoretical and methodological tools produced in the discipline of Mathematics Education to regulate and innovate their teaching practice. Since 2013 we have been designing and delivering courses based on the REI-FP methodology (Sierra 2013 and Ruiz-Olarría 2015). This communication analyses elements of latest edition with the aim of showing "successes" and challenges, recognizing the particularities of online mode and multimedia devices.
