Last week, I shared a link to OpenStax, a site that offers free college level textbooks. Several of you wrote back saying that it was an interesting idea, but the text was too challenging for middle or high school students.
If so, you should check out today’s site from the CK-12 Foundation. The website includes free textbooks in STEM subjects with video and audio built in that allow students to interact with the material. They even have physics simulation modules and PLIX (play, learn, interact, explore) that allows students to “explore [STEM] concepts often used in real world examples.”
Check it out and let us know what you think!
