In the Manage Variation Preferences section, you can change the point value for each step in a Grader Project question and set for which steps students should see hints.
To manage variation preferences for a question:
Click the Manage Variation Preferences section. A new window opens, showing each step by number, the step instructions, the current point value, an option to change the point value, and whether the hint is visible to students.
The Instructions column lists the instructions available to students when they are answering the question.
The Point Value column shows the current point value for that step. A point value of zero means the step is not included in the grading evaluation, but the student will still need to complete the step.
To change the point value for a step, select a new point value from the Change Point Value column. Select the desired point value from the drop-down list.
In the Show Hints? column, you can indicate if you want hints to appear to students as they are completing a Grader Project question. By default, this is set to No, so that hints do not display. To display hints to students for a specific step, click the Yes option button. The hint will appear to the student as ”Hint:&ldots;” within the question text.
Note: If you want to view the specific hints after clicking Yes to display them, click Save and Close to save the changes and then click the Manage Variation Preferences section header again.
When you are done you can select one of the following options:
Save and Close: Save any changes you made and close the window.
Reset all to defaults: Cancel any changes you made and display the original question preferences in the window.
Cancel and return to the question edit screen: Cancel any changes you made and close the window.
Note: Each step may have different variation options. Therefore, you may not be able to change the hint display or point value for every step in the question.
