Graham Gibbs' model of reflection outlines a framework for critically reflecting on experiences. The model consists of six stages: 1) Description - describing what was observed and the context of the situation, 2) Feelings - identifying thoughts and feelings during the experience, 3) Evaluation - assessing what went well and could be improved, 4) Analysis - linking the experience to learning, 5) Conclusion - considering other actions that could have been taken, and 6) Action Plan - determining next steps to apply the learning. The goal is to gain deeper insights from experiences by systematically working through each stage of critical reflection.
