This presentation discusses Open Educational Resources (OER) and high impact OER adoption. It defines OER as resources with free access and permission for users to retain, reuse, revise, remix, and redistribute. Studies show OER improves affordability and student success compared to commercial textbooks. High impact adoption invigorates pedagogy through reusable assignments and entire OER-based degree programs. The open nature of OER allows new opportunities to enhance teaching and learning.
