Q. How does using OER affect learning outcomes for students?
Studies at both the K-12 and higher education levels show that students who use OER do as well, and often better, than their peers using traditional resources. In some cases, this is believed to be the case because all students are able to access their learning materials when they are free. However, being open or closed does not inherently affect the quality of a resource. What matters is that the materials meet the needs of a course and are integrated into a curriculum well.
NOTE: Being open does enable educators to use a resource more effectively because they can be adapted. OER can be updated, tailored, and improved locally to fit the needs of students.
