An article in the Chronicle of Higher Education posted today at http://chronicle.com/article/In-Students-Minds-Textbooks/231455/ provides more reason to adopt open educational resources.
“A survey of undergraduates on 23 campuses by the National Association of College Stores, expected to be released on Thursday, found that students spent an average of $563 on course materials during the 2014-15 academic year, compared with $638 the year before.” The article goes on to indicate that students are opting out of purchasing required materials. However, “a separate survey of professors on the same campuses, meanwhile, found that they almost never see the course materials as optional.”
