Evaluation of a Simulation Training Tool to Identify Lesions Requiring Further Screening for Melanoma

The investigators will design a curriculum for visual screening for melanoma and skin biopsy procedure, based on the mastery learning model, using simulators and web-based didactic instruction for medical students and internal medicine residents. This requires having a skin simulation model that presents a range of lesions from benign nevus to atypical nevus to melanoma in a distribution and density that mimics the clinical findings of those with 2 skin tones: fair-skin non- Hispanic white and Hispanic.
