General Resources
"Open education sites exemplify how technology is democratizing education. These sites allow both learners and teachers to create their own curriculum, whether it’s used in or out of the classroom.
Here’s a comprehensive list of open education sites MindShift has covered. "
Open Materials
Open Textbooks
"Open textbooks are real, complete textbooks licensed so teachers and students can freely use, adapt, and distribute the material. Open textbooks can be downloaded for no cost, or printed inexpensively."
Open Courses
"The ChemCollective is a collection of virtual labs, scenario-based learning activities, tutorials, and concept tests. Teachers can use our content for pre-labs, for alternatives to textbook homework, and for in-class activities for individuals or teams. "
