In fall of 2018, a cross-campus team of academic professionals at Salem State University, a regional comprehensive institution in Massachusetts, launched a strategic and programmatic OER and textbook affordability initiative. In this session, the team (comprised of a faculty member and the heads of the library and of academic technology) will discuss how they have taken an innovative approach to building an OER initiative through coordinated and intensional faculty development. They will examine how integrating multiple types of faculty development activities have kickstarted OER adoption and creation on campus by meeting faculty at their experience level (beginner to advanced) and learning style (individual to collective). The session will describe four types of learning activities that offer faculty a range of options for OER professional development, which faculty can select according to their level of experience and personal learning preferences. Presenters will also discuss the results of surveys of their faculty and students about perceptions of OER and will use Polleverywhere and small break-out groups to integrate audience participation in the discussion. This presentation will be especially instructive to individuals who are just getting started or want to start a programmatic OER initiative on their campus.
