This presentation discusses open educational resources (OER) and their benefits. OER are teaching and learning materials that can be freely used and modified. The presenter argues that adopting OER through entire degree programs (replacing all required textbooks with OER) can significantly improve affordability for students, increase student success rates, reinvigorate teaching methods, and achieve these benefits at scale across many students and institutions. The presentation cites research showing positive impacts of OER adoption on student outcomes like course completion rates and credits earned. It encourages moving beyond just swapping textbooks to fully leveraging the capabilities of OER, such as creating renewable assignments that students find valuable.
