Gladys Scott shared a Google+ message with me about a presentation that she is giving this weekend. The presentation she is running is about CK-12 Flexbooks. In advance of that presentation she has released a short video tutorial on how to create CK-12 Flexbooks for mathematics. The video is embedded below.
Applications for Education
Tools like CK-12 Flexbooks can be very useful for producing reference materials that are tailored specifically to your curriculum and your students' needs.
