The latest developments of DynaLern (software, models, educational materials) are being shown to students, teachers and businessmen in Madrid, from the 22 to 26 February, in the “Salón Internacional del Estudiante y de la Oferta Educativa” (AULA 2012). Based on previous years, four thousand people are expected. Visitors will be received in a nice stand with posters, videos and people from UPM and FUB to explain our project. A new post will comment the reactions to DynaLearn!
