It defines OERs and Z-courses, and notes their growth at MC from 2017-2018. It discusses drivers for these initiatives like rising textbook costs. Data shows most students couldn't afford required materials. Surveys found Z-courses had equal or better outcomes than non-Z courses. Barriers and lessons learned are presented. The goal of increasing access, equity and affordability while maintaining quality is emphasized.
