The document summarizes the evolution of the Department of Medical Education at UMMS into the new Department of Learning Health Sciences. The new department broadens the scope to focus on learning at different scales from individual to organization-wide. It aims to advance the science of learning applied to health through research, education, and promoting continuous learning and improvement within health systems to make them "learning health systems". Realizing this vision requires overcoming challenges through new learning sciences and building collaborations across different fields.
