Impact of OER in Teacher Education (2020)The purpose of this research study, which employed a quantitative research design, was to determine if there was a difference in the grades achieved by students who were enrolled in an entry-level Foundations of Education course using Open Educational Resources (OER) versus the grades achieved by students who used textbooks in other course sections. The goal was to find out whether OER was of the same or higher quality as textbooks in our minority-serving higher education institution.
