ABSTRACT
It is generally assumed that a career in science begins in the university, a site in which students receive not only theoretical instruction but also practical education in order to master the skills that a discipline requires. In addition, university professors and researchers show students a set of accepted behaviours and rules that they must follow during their careers as well as a series of images of what it means to be a good scientist. Students draw explicit knowledge about specific topics or problems in their discipline from theoretical instruction. They learn by means of practical exercises how to deal with theoretical knowledge in order to appropriate it and use it.
