The Review Status tool allows instructors to track user review of specific content items. After an instructor turns on the tool for an item, students track their progress. A Needs Review button appears with enabled items. After reviewing the item, a student selects this button to mark it Reviewed.
If the Review Status tool is turned off, all data is saved. If the tool is made available again, all user entries will appear and be unchanged.
