eClass enables you to manage access to resources and activities in your course, based on dates, grade, group, grouping, user profile fields or a combination of above variables. This eClass feature provides considerable flexibility in managing access to course elements.
For example, you may only want to allow access to an activity between certain dates, regardless of the release date set on it. An assignment could have a release date in the third week of your course with only its description being made available. You may then want to restrict access to access the assignment between week two to week four.
Another scenario might be that students need to complete a quiz or research activity before being allowed to complete a related assignment. Access could be further restricted by setting a minimum grade requirement on a per-activity basis.
