Open Educational Resources (OERs)

Open Educational Resources (OER) are free, customizable teaching and learning materials that support student success, academic freedom, and equitable access to education. At Purdue, we support instructors in adopting, adapting, and creating OER to reduce costs for students and enhance classroom engagement.
On this page, you’ll find the benefits of using OER, practical ways to get started, tools for finding and modifying resources, and support available through Purdue Libraries.
The Benefits of OERs
- Retention/Student Success: OERs can help to make education more accessible. OERs are available online and can be accessed from anywhere.
- Support Teaching and Learning: Instructors can use OERs to create their own lesson plans or to supplement existing materials. Students can use OERs to learn new material, review for exams, or complete assignments.
- Promote Equity in Education, Teaching, and Learning: OERs can help to make education more affordable. The cost of textbooks has been rising steadily in recent years, and this has put a strain on students’ budgets. OERs can provide students with free or low-cost access to high-quality learning materials, which can help to reduce the financial burden of college.
- Adaptability: OERs promote discovery by providing students with access to a wide range of learning materials, including scholarly articles, videos, and simulations. This can help students to explore new ideas and to learn about different perspectives.
- Active Learning: OERs can help to engage students by providing them with opportunities to participate in active learning activities. This can help students to learn more effectively and to develop critical thinking skills.
