This article analyzes Problem-Based Learning as a methodological strategy to foster critical thinking; it is based on a mixed research approach supported by the deductive-inductive, phenomenological and hermeneutic methods. The effects of this strategy on the teaching work are examined and a series of didactic guidelines are proposed to support the development of this skill.
