The Council of Independent Colleges (CIC) received a grant from the William and Flora Hewlett Foundation in 2020 to explore the potential of open educational resources (OER) to reduce textbook costs for students at smaller and mid-sized independent colleges and universities, especially Historically Black Colleges and Universities (HBCUs) and other Minority-Serving Institutions; to understand how OER are being used at these institutions; and to learn the extent OER can support more equitable teaching and learning. A key objective of this project was to produce a research report on the use of open educational resources at small to mid-sized independent colleges and universities that are CIC members, detailing the successes and challenges of existing OER projects at select CIC member institutions. This project focused on those institutions that serve historically underrepresented student populations in higher education, such as students who identify as Black or African American or Latinx, students who are the first in their families to pursue a postsecondary education, or students from low-income households. The first phase of this work involved CIC conducting a survey of a subset of its membership to understand the landscape of initiatives to use or create OER for undergraduate courses and what has been done on an institutional level to incentivize the use of OER across the colleges and universities. Following the survey, a select group of CIC member institutions were interviewed to develop a set of case studies. These case studies outline OER strategies and efforts at a wide range of independent colleges and universities serving historically underserved students and include a discussion of the factors for success at these institutions.
