A community college reform group has selected a handful of schools in Virginia and Maryland to develop degree programs using open-source materials in place of textbooks, an initiative that could save students as much as $1,300 a year. Such open educational resources — created using open licenses that let students download or print materials for free — have gained popularity as the price of print textbooks have skyrocketed, but courses that use the materials remain a novelty in higher education. Achieving the Dream, an education advocacy groups based in Silver Spring, Md., aims to change that by offering $9.8 million in grants to support the development of open-source degree programs at 38 colleges in 13 states.
