What college student doesn’t like free textbooks? Heck, you tell your parents to send money for texts, use free ones, and you pocket the rest, right? Boundless, a site that uses Creative Commons textbooks, will allow you to do that. Of course, K12 Open Source Classroom will not condone that though!
Boundless (www.boundless.com) seeks to provide open content to students. They work with the Open Educational Resources community to provide this free content.
So you go to the site, create an account, and choose your school and then classes. This is exclusively a higher ed entity at this time, but I can definitely see the promise for high school in the future. As you go through your courses, you will find some open textbooks. It does not seem like all the courses provide open texts, but my school I used to sign-up, North Carolina State (go Wolfpack!) has some using Boundless. You can also just browse an entire list of available texts at https://www.boundless.com/textbooks/. You can find a wide variety of courses from Accounting to Art History and from Marketing to Microbiology. When you drill down into a course you find a nice outline, and then your actual text. Boundless also provides other materials like study guides, quizzes, and flash cards for registered users. Pretty nice tool!
How great for a college student! If all their classes supported this, they would probably only need something like a tablet device for school. Instead of the hundreds of dollars put toward textbooks, put that to a device (although making sure to put a little to the good folks at Boundless who run the site–they need to eat too!). Do the publishers like this? Of course not, but they have had their run. Now it is time for us to shift directions, getting more crowd-sourced, current information. More engaging and interactive content as well. Now, just to see it at the high school level!
