Evidence Based Education in Thoracic Ultrasound

The goal of this cluster randomized controlled trial is to evaluate if a web-based thoracic ultrasound (TUS) training program can effectively educate users non-inferiorly to traditional classroom teaching in physicians and selected healthcare professionals attending scheduled TUS courses. The main questions it aims to answer are: * Will participants in the web-based learning group achieve non-inferior theoretical test scores compared to the class-based group? * Will participants in the web-based learning group achieve non-inferior practical test scores on an ultrasound simulator compared to the class-based group? Researchers will compare a traditional class-based learning group (receiving preparational material, oral presentation, and class-based cases) to a web-based learning group (receiving interactive web-based reading, tasks, videos, and quizzes) to see if the web-based approach yields non-inferior educational outcomes and skills retention. Participants will: * Complete pre-course preparation (90 minutes) and a theoretical pre-test (30 MCQs). * Undertake either class-based or web-based theory and clinical integration training (3.5 hours total). * Perform hands-on ultrasound training on healthy volunteers and a simulator (2 hours 30 minutes). * Take a practical post-test using an objective structured assessment on a simulator. * Potentially return for a voluntary retention test (theoretical and practical) to achieve certification.

Inclusion Criteria: * Healthcare professional professionals attending the regional simulationscentres TUS Courses. * Provided consent to include their test results and data in the study in connection with the first theoretical test. Exclusion Criteria: \- None (participants can complete the course without participating in the study if they decline consent, but there are no clinical or demographic exclusion criteria for the study itself).
