You can restrict access to an assignment so that only students meeting certain criteria can take the assignment. You can also create assignment requirements that refer to the current assignment, even if you are working with a new assignment that has not yet been saved. The assignment on which you are working is now listed along with all other available assignments in the Criterion specification box. This is useful when you want to ensure minimum competencies in prerequisite topics. For example, you can limit access to students who have already passed an earlier assignment.
To restrict assignment access:
From the Assignment Editor screen in the Set Policies tab, click Advanced. The Set Policies - Advanced screen with a Requirements field is displayed.
To set criteria, click Design. A Criterion 1 rule based field opens. The program adds input fields for the first criterion, as shown:
The program automatically propagates the settings in the Criterion panel to the Requirements panel, and updates the criteria in this field as soon as you select a different option from the list. You do not need to take any action to add the criterion to the text area.
Note: You can also enter the criterion directly in the Requirements field, but using the Designer is recommended.
The first drop-down list gives a choice between has and has not.
The drop-down list in the middle lists a range of states and actions, as shown.
The drop-down list on the right lists all of the assignments for the class, including the assignments whose restrictions you are defining.
Adding an OR Criterion: Click the Add alternative criterion button immediately below the list of assignments. The program adds the list fields for another criterion.
Adding an AND Criterion: Click the Add alternative criterion button at the bottom right of the form, below the frame that encloses the criterion fields. The program adds another criterion group, in a separate frame.
Deleting a Criterion: To delete an OR criterion, click on the Remove criterion button inside the frame for that criterion group. The program deletes the last criterion from the group. You may have to change the settings for the remaining criteria in the group to set the requirements that you want. To delete an AND criterion group, click on the Remove criterion button at the bottom of the form, below the last criterion group. The program deletes the last group. You may have to change the settings for the remaining groups to set the requirements that you want.
Save Changes to Criterion: To close the Set Polices -Advanced page and save changes made to the criteria, click the Set Policies tab.
