Sometimes your students will not finish a learning experience before it ends. Once ended, students can view a learning experience but they can no longer work through it or edit their answers.
If a learning experience ends, and you have some students who have not yet finished and you would like them to finish, you can reactivate the learning experience.
NOTE: Reactivating a learning experience does so for all invited students, not just the students who have not finished.
To Reactivate a Learning Experience
Go to your Ended Experiences, roll over the learning experience you want to extend, and click Reactivate.
This will reactivate the experience for 24 hours. If you want to extend for longer, you can change the End Time by following the steps in this article.
