Releasing the results to the students can be done in two ways:
Releasing the results through LTI. Go to ‘Rating form’ and click on ‘Release results?’ toggle.
Releasing the results through VLE. Follow the steps for Releasing the results through LTI. Then go to the ‘Students’ tab and at the bottom of the page select the option to ‘Update VLE with results’. This will push the results into the Gradebook (on Moodle). Once the update is finished, a message will appear indicating so.
