The idea that one learns to do research only by taking methodological courses is false, as it is false the idea that one learns how to do research only through investigative practice. We consider both strategies pertinent and necessary and that is the reason we believe graduated courses based on investigation must contemplate both. This study aims to share with the academic community the concept, the intention, the context, and how the Seminar on Lines of Research in the Collective Health Master's Program at the University of Antioquia, Colombia has been developed. This study emphasizes the development and the results of such experience in the education of researchers, describes its onset, the curriculum structure and the relationship with the research groups, the transformation of students and the professor's role.
