In this context, how does critical thinking contribute to generating new knowledge? Many authors attempt to explain and define critical thinking. Objective: The purpose of this paper is to discuss the most relevant critical thinking models and to develop a model for this personal attribute in doctoral education. Materials and methods: Seminal works and the most significant models of critical thinking were reviewed in the current literature. Results: A critical thinking model in doctoral education was developed as an integration of the most important contributions of all authors. Conclusions: We argue that there is not a unique definition for this concept and that critical thinking may be understood as a process rather than as a tool, attribute or skillenAcceso abiertoCorporación Universitaria LasallistaConocimiento científicoGestión del conocimientoPensamiento críticoinfo:eu-repo/semantics/openAcces
