In order to facilitate robust and engaging learning experiences, educators and students rely upon the ability to freely exchange ideas and educational content. But that’s not always easy to do because most publishers and authors of educational materials explicitly restrict your ability to copy, share and modify these resources through copyright, passwords, or other means. Open licenses, such as Creative Commons licenses (also known as “CC licenses”; página en español: https://creativecommons.org/licenses/?lang=es_ES), clearly state how the author wants you to use their materials, and give you the right to freely copy, modify, adapt, and build upon those materials for your desired use.
