The document summarizes research from the OER Research Fellows program about open educational resources. It discusses the purpose of the program, which is to encourage high-quality OER research and build researcher capacity. It provides an update that several articles have been published or accepted for publication. It then highlights research from two Fellows, Judy Orton Grissett and Huimei Delgado. Orton Grissett's research found students perceived faculty more positively when they used open textbooks. Delgado's research at Purdue University found lower withdrawal rates but similar exam performance when using free OER instead of a $121 textbook. The document ends by calling for more rigorous OER research designs.
