High Impact OER: Connexions and OpenStax College Daniel Williamson, Richard Baraniuk & David Harris, OpenStax College, US Phyllis Hillwig, Words and Numbers, US Conference Theme: Impact Abstract: Limited access to higher education is one the greatest challenges facing students today both in the US and abroad. For many years, going to college was an opportunity to which only the wealthy could aspire. Yet, even with the great amount of scholarships and government aid available, many students still cannot afford college. One of the commonly overlooked costs associated with college affordability and student success is the ever-increasing price of textbooks and other learning resources. This is especially visible in the US community college space, where the cost of textbooks often exceeds the price of tuition. It has been documented that students are simply choosing not to purchase textbooks. OpenStax College, an initiative of Connexions (cnx.org), one of the world's first and largest OER repositories, is improving student access to quality learning materials. OpenStax College (openstaxcollege.org) brings together the innovative publishing features of Connexions with the rigors of professional content development and academic peer-review. OpenStax College plans to provide turn-key open textbook solutions for the 20 most popular US community college courses and beyond.
