This document discusses open textbooks and open educational resources (OER). It makes three main points:
1. Education is about sharing knowledge, and digital technologies allow unprecedented sharing through free copying, distribution, and editing of educational content. Open licensing like Creative Commons allows this type of open sharing.
2. Using open textbooks and OER can significantly reduce the cost of textbooks for students, saving millions of dollars. Research shows students rate the quality of open textbooks as equal to or better than traditional textbooks.
3. Providing open educational resources along with professional development for teachers allows them to adapt materials for better pedagogy, like highlighting, annotating, and adding notes. This can move the needle on learning outcomes
