Designed around an OER Scaling and Sustainability Playbook, this workshop invites OER veterans and newbies to explore: 1) What are the common challenges around growing OER adoption, and what are successful strategies for tackling these challenges at your institution? And 2) What models are institutions pursuing to sustain their OER initiatives, and which might be a good fit for you? During the session, you’ll use the Playbook as a diagnostic tool to identify strategies to help you achieve your goals for making a significant impact with OER. We’ll also invite the group to recommend additional strategies and tactics to broaden the Playbook as a useful resource for the OER community.
