5R's of OER


Open Educational Resources (OER) are defined as teaching, learning, and research materials that are either (a) in the public domain, or (b) openly licensed in a manner that provides everyone with free and perpetual permission to engage in the 5R activities. The 5Rs are defined as:

  • Retain – make, own, and control a copy of the resource
  • Revise – edit, adapt, and modify your copy of the resource
  • Remix – combine your original or revised copy of the resource with other existing material to create something new
  • Reuse – use your original, revised, or remixed copy of the resource publicly
  • Redistribute – share copies of your original, revised, or remixed copy of the resource with others


Zero Textbook Cost (ZTC)


Zero Textbook Cost (ZTC) courses are those that are designated free from high costs traditionally associated with commercial textbooks. Faculty designate courses ZTC in the course schedule if they use OER or other free, or low cost options in their courses. Check out the short video below to find out how students can find ZTC courses in the Grossmont class schedule.
