Facilitating Critical Thinking in Undergraduate Medical Education: An Integrated Narrative Review

Abstract

Critical thinking is a central goal of undergraduate medical education because students must learn to interpret evidence, question assumptions, compare competing explanations, and justify decisions under conditions of uncertainty. Although the literature contains many accounts of barriers to critical thinking, the evidence on conditions that facilitate its development is more dispersed across studies of active learning, clinical reasoning, feedback, student engagement, higher-order thinking, and faculty facilitation. This focused narrative review integrates that literature into three cross-cutting domains rather than treating individual teaching techniques as isolated facilitators. The first domain is pedagogical architecture: active, problem-oriented, and cognitively demanding learning designs that require students to analyze information, explain relationships, and make decisions. The second is the relational learning climate: psychological safety, dialogic feedback, questioning, and guided reflection that make it possible for learners to expose incomplete reasoning and revise it. The third is faculty cognitive apprenticeship: making expert reasoning visible through facilitation, modeling, think-aloud explanation, mentoring, and deliberate scaffolding. Evidence is strongest for active and problem-centered approaches, including problem-based learning and concept mapping, while the evidence for relational climate and role modeling is more qualitative and context-dependent. The review therefore argues against treating critical-thinking development as the product of any single method. Instead, critical thinking is most plausibly supported when curriculum design, feedback practices, learner participation, and faculty reasoning are aligned. The review also identifies important limitations in the field, including inconsistent definitions of critical thinking, frequent conflation with clinical reasoning or academic performance, reliance on single-site studies for several relational facilitators, and limited cross-cultural or longitudinal evidence. Future research should test integrated models of facilitation using multi-institutional and mixed-methods designs and should distinguish clearly between critical-thinking skills, dispositions, clinical reasoning, and general learning outcomes.
