Excellent primer on the open textbook publishing model: what it is, how it works, who’s doing it, why it’s significant.
“The open textbook publishing model offers new collaborative opportunities for authors, who can join communities of writers on sites that offer open licensing. Authors, illustrators, and editors can choose to contribute many types of course content to the growing field of open educational resources, including essays, animations, video demonstrations, detailed drawings, and classroom activities—all without taking on the burden of writing an entire book.”
What’s really important is that this is not all about solving for the cost issue. It’s about creating textbooks that are truly engines of learning, by letting those who are in the trenches and know best what’s needed (teachers) drive the (textbook publishing) bus.
