At the end of each module, participants will be asked to rate their confidence in answering triaging lesions on a scale of 1-10. The change in confidence rating between Module 1 and 4 will be tracked. Students will also be asked to answer a post-test questionnaire designed to assess: i) the usability of this course ii) effectiveness of this course in helping students triage benign and malignant lesions. Usability will be assessed with the System Usability Scale. Effectiveness of the course will be assessed with questions tailored to assess the specific learning objectives.
