It is necessary to know the opinions, practices and expectations of teachers in training and in practicing, to improve teacher education programs. This Handbook addresses the challenges for the profession of teaching of history and geography, who, in several European countries such as Spain and France, share initial training and teaching in both disciplines. Researchers? contributions have been collected from eight countries. The majority of Spanish universities, eleven, have shared an extensive research project, but have also had the collaboration and participation of researchers from seven other countries: Brazil, Canada, China, Colombia, Portugal, Sweden and the United States. It is about collective work, in a network, rather than the sum of individual contributions.
