This document summarizes a study on shifting educator perspectives and practices through an online professional development course on open educational resources (OER) at the Open University of Sri Lanka. The course aimed to build educators' capacity to reuse, revise and remix OER for innovative learning experiences. Survey results found the course increased educators' understanding of OER concepts and skills in identifying, evaluating and integrating OER. Factors like course design and peer support facilitated learning, while time constraints hindered it. Impacts included changes in mindsets and practices regarding OER adoption. The study concluded the course significantly impacted educators' abilities to engage in OER-based e-learning.
