In 2019 and 2021, the THECB partnered with ISKME and DigiTex to conduct surveys and landscape analyses of OER in Texas higher education. The data collected surfaced numerous insights, including that the institutions most advanced in their open education policies and practices provide comprehensive, systems-based supports for OER by engaging multiple offices and roles across campus. Given this, one of the recommendations in the 2021 report included creating a state OER Playbook to support institutions as they work to build capacity and drive systems change around OER. Together, the THECB and ISKME, with support from a statewide Advisory Committee, developed the OER in Texas Playbook, which has two primary objectives: Outline the steps needed to implement the change management inherent in an institutional shift to OER. Provide resources for the localization and contextualization for each of the Texas institutions that choose to take part in [a] Playbook Development Academy. In this session, geared toward all levels of expertise, presenters from ISKME and the THECB will discuss the research-based genesis of the playbook and its development process and give a quick tour of the guide. Attendees will have the opportunity to ask questions and consider ways to adapt the openly licensed resource for their own contexts.
