Release conditions allow you to create a custom learning path through the materials in your course by controlling how and when students access certain course items. When you attach a release condition to a course item, students cannot see that item until they meet the associated condition. For example, you can require that students meet certain criteria, such as reading a set of lecture notes in the content area, before they can submit their work to an assignment. You can also make submission to the assignment a criterion for accessing another item, such as a quiz.
On the nav bar, click Activities, then select Assignments.
On the Assignments page, from the context menu of the assignment you want to set release conditions for, click Edit Assignment.
Select the title on the Availability and Conditions panel located on the right side of the page to expand these options and set your preferences.
Click Add Release Conditions.
Do one of the following:
Click Create New, then select a Condition Type. Complete any additional Condition Details that appear and click Create.
Click Add Existing. From the View Conditions for drop-down list, select the tool in which you want to view existing release conditions, select the release condition you want to attach, and click Attach.
