Approximately 15 states are changing their policies to give school districts more flexibility in acquiring content. They have changed laws or policies or have bills pending in state legislatures to redefine "textbooks". Most of those changes are similar to the approach Indiana took in its new law: a "textbook" is not only a book but also "computers and other data devices, instructional software, Internet resources, interactive, magnetic media, and other systematically organized material." Digital content often contains more current and relevant information than can be found in traditional textbooks. Resources can be reallocated to support technology when content delivery is flexible. Open educational resources are changing the teaching culture and the relationship between learning and technology in many schools.
