This document summarizes a presentation about exploring open educational resources (OER). The presentation addresses the high cost of textbooks as a problem, and introduces OER as a potential solution. It defines OER and distinguishes them from other zero-cost materials. Research is presented showing that using OER can improve student outcomes like course completion rates and grades, especially for lower-income students. Potential benefits of OER beyond cost savings are discussed. The presentation explores "OER-enabled pedagogy" involving students creating and customizing OER. Common concerns about quality and other factors in selecting course materials are acknowledged. The presentation concludes with a group exercise and invitation for further discussion.
