This case study examines student learning outcomes derived from the redesign of an undergraduate child development research methods course, replacing a commercial textbook with Open Educational Resources (OER), which were remixed into interactive lessons. Using survey and exam performance data, two areas were evaluated: 1) students' experiences with the OER lessons; and (2) students' exam results from two OER sections compared to two previous commercial textbook sections taught by the same instructor. No significant differences in exam performance between the two groups were observed; however, student perceptions of the OER lessons indicated strong satisfaction. Implications of these findings, such as OER benefits for teaching and learning, are discussed.
