Open Licensing and Reuse
Understanding Creative Commons Licensing: A Practical Guide for Tanzanian Teachers
When you find Open Educational Resources (OER), the licence tells you what you may do with the material. Creative Commons (CC) licences make it clear whether you can copy, adapt, translate, remix, and share. This guide explains each licence in simple terms so you can confidently use OER in Tanzanian classrooms.
What is Creative Commons?
Creative Commons provides free, standard licences that creators attach to their work. With the right CC licence, you may use, keep, modify, translate, and share materials—as long as you follow the licence conditions. Learn more at https://creativecommons.org.
CC Licence Elements

| SA | ShareAlike — if you adapt it, you must use the same licence on your new version. |
