I am a Senior Lecturer at the Faculty of Psychology at UAM. I have been Director of the CNIIE (Ministry of Education – Spain) and of the IUCE of UAM. I have done research on conceptual change in history, the development of narratives, and historical thinking. I believe that now more than ever the acquisition of historical knowledge, that takes place in formal and informal contexts, is essential not only for understanding the past, but also for interpreting and acting in the present.
