Twelve tips for using image challenges to teach clinical reasoning

Image-based challenges—visual material paired with a short clinical vignette—offer an efficient, authentic, and low-cost way to make reasoning visible and to give learners repeated, guided practice. This article offers twelve practical tips for educators who wish to teach clinical reasoning through image challenges.

The first tips start from learning objectives, ground the method in reasoning theory and the evidence on observation-based learning, and address the curation of authentic images and the organisation of small-group sessions. Four complementary formats follow, each described as a reproducible step-by-step activity: a multiple-choice challenge; assessment of general condition with dual-process thinking; comparative reasoning with progressive disclosure that exposes cognitive bias; and images that link diagnosis to management and social determinants of health.
