Good news! Activity completion or completion tracking, available in Moodle 3.4, lets students see their progress through their Moodle course through the use of checkboxes on the side of activities. There are two types of checkboxes to help your students: dotted and solid. The boxes with dotted lines are automatically ticked when a student hits a certain criteria, such as completing a quiz. Whereas the boxes with solid lines can be clicked manually by students to display that they have completed the activity.
