The document outlines a 2-year research project funded by the William & Flora Hewlett Foundation, aimed at analyzing the impact of Open Educational Resources (OER) on student performance and satisfaction. Findings from surveys revealed that over 60% of students and educators experienced increased satisfaction and interest in subjects due to the use of OER, with significant financial savings reported. The research also highlighted the collaboration model employed, along with an impact map hosted on the OER Research Hub, to further disseminate findings and encourage contributions to a comprehensive study on OER impact.
