Learning Sciences research has long established that the development of competence is predicated upon the initial acquisition of declarative knowledge (knowledge of what), followed by instructional activities that enable learners to transform their recently acquired declarative knowledge into procedural knowledge (knowledge of how to). Lectures and focus sessions such as our 2022 IAMSE focus presentation titled "An exploration into how clinical and basic sciences faculty perform 'diagnostic' problem solving" represent declarative knowledge. With this year's proposed workshop, we will once again impart declarative knowledge describing our current understanding of how basic and clinical sciences faculty solve diagnosis-oriented patient problems (in accordance with Dual Processing Theory's (DPT) description of how two cognitive mechanisms, referred to as System 1 and System 2, are used to perform the task of differential diagnosis).
