Hunting the Whole Enchilada: 6 Excellent Sites for Free Digital Textbooks -- THE Journal

"Plug 'digital resources for k12' into Google and you'll get a bazillion results (or maybe it just seems that way). Head to any resource site for teachers and you'll lose yourself in a miasma of links. Thinkfinity will link you to Smithsonian, which will direct you to HippoCampus, and onto Kahn Academy, and over to Curriki, and off to — well, you get the picture. As wonderful as those sites are, sometimes you don't want to spend all your planning time piecing together a school year's worth of lessons from a multitude of online sites. You just want the whole enchilada delivered in textbook form from which you can select the content you'll assign to your students. To that end we have hunted down the top sources for digital textbooks — all free. What you and your students do with them on the iPads and Chromebooks in your classroom is up to you. California Learning Resource Network (CLRN) The current compilation of open educational resources (OERs) on CLRN stands at 6,063. If you're teaching high school-level math, science, history or social science, what you want to pay attention to is the free textbooks link, of which there are 30. The site counts up standards met for many of the textbooks; but since they're being compared to California education standards, that metric may or may not be of use to you, depending on what state you're teaching in. As an example, Light and Matter is an introductory 1,016-page textbook on physics published by Benjamin Crowell, a faculty member at Fullerton College in Southern California. The PDF is a whopping 80Mb, full of graphics and color images. He makes an instructor's guide available for the text on his Web site. The site also includes an ample number of non-textbook OER resources for grades K-12 that meet Common Core standards. You can filter results by subject, grade level, and type of resource. CK-12 Foundation This pioneer in the field of OER has a simple student interface. Go to the home page, pick a topic, and choose a 'FlexBook' from what's listed. English has three offerings (one a teacher's edition), history has two, math has five (all for middle school), and earth science has five. This is one of the few resources that actually allows reviewing. For example, CK-12 Earth Science Concepts for High School gets 11 thumbs up, no thumbs down, and two reviews, both positive. FlexBooks can be downloaded in three forms: PDF (for most computing devices), mobi (for Kindle), and ePub (for iPad and Android devices). Users have to sign in for access to the textbooks but you can use your Google, Facebook, or Twitter account for that. Once you've provided that, you'll receive a confirmation email that will guide you back to the site for your downloads. The earth sciences textbook referenced above, for example, written by science writer Dana Desonie, runs 1,208 pages in PDF format.
