This document describes a research study using a MOOC to investigate how searching online for medical information affects the doctor-patient relationship. The MOOC asked participants to diagnose six medical case studies and complete surveys. Over 200 people participated, and data collection is complete. Preliminary results found high rates of online medical searching and a strong correlation between MOOC participants' diagnoses and doctors' diagnoses. The study aims to provide insights into the benefits and risks of online medical searching and its impact on healthcare. MOOCs show potential as a research tool but also have limitations like self-selection bias and low completion rates that must be considered.
