An understanding of learning theories can help adult educators become more effective practitioners and meet the needs of the learners they serve. Adult educators who understand how individuals learn can be better prepared to use effective strategies during the learning process. This article addresses the use of concept maps as a strategy to engage adult learners in critical analysis, a skill educators often aim to help learners strengthen. The discussion situates within four learning theories: cognitivist, constructivist, transformative, and social learning. Examples from different contexts using concept maps and connections between theories, learning process, locus of learning, teacher's role, manifestation in adult education, and activities are presented. The article concludes with putting concept maps and critical analysis into practice in formal and nonformal settings.
