This is a new feature as of 2018/SU with our update to Moodlerooms 3.4 and provide instructors with a means of toggling the completion status of assigned work in a Moodle course.
These steps require that you have Completion Tracking enabled and applied in your course.
Enter the course in question.
Expand the Actions Menu (Gear icon) from the top-right corner of the page.
Select the More… option from the very bottom of the menu.
Under the Course Administration tab you’ll find the Reports section.
Select the Activity Completion option.
Moodle will generate a grid of activity completion statuses, users will be listed along the side and activities at the top of the grid.
Click on the the completion status checkbox you wish to override.
A popup will appear to ensure this is intended.
Click the Save changes button to apply your override.
Manually applied activity completion check boxes will appear much brighter in color to set them apart from the otherwise normal, grey items that have not been modified.
Repeat as desired.
Instructors can return to this page and modify or make additional overrides at any time.
