This document discusses open educational resources (OER) and how they can benefit K-12 education. It defines OER as teaching materials like textbooks, videos, and exams that are free to access and allow users to engage in 5R activities of retaining, revising, remixing, redistributing, and repurposing. Studies have found OER can save school districts millions of dollars annually in textbook costs while empowering teachers and keeping content up-to-date. The document provides examples of how OER are being successfully implemented and recommends steps superintendents and administrators can take to support OER adoption.
