This document summarizes the reasons why open educational resources (OER) should be adopted. It notes that higher education is both important and expensive, with rising textbook costs being a major factor. The traditional textbook market is also inefficient, with few major publishers controlling most of the market. As a result, many students cannot afford required textbooks or materials. OER provide a solution as freely accessible teaching and learning materials that can be customized by faculty and accessed by students at no cost. The presenter outlines initiatives in British Columbia to create open textbooks for high-enrollment courses and engage faculty in reviewing, adapting and creating new open resources.
