2.6 Scaling Grades

This scenario demonstrates the graphic grade scaling functionality of the Grader tool.� Using the Grader tool, the instructor is able to use graphs to scale the grade distribution of the class. This functionality helps the instructor to have a visual understanding of what the grade break down is and the ability to easily make changes directly on the graphs until the grade distribution is to his liking.� It also allows for students to predict their grades by predicting the grade breakdown.

The grade scale functionality has three modes of operation: the pie chart, the histogram, and the data table.� The user can choose to use only one or all modes of operations at the same time.� Whatever changes are made in one mode will be reflected on the other modes as well.

Each grade is assigned a color to give better indication of the grade breakdown.� The user can change the color of each grade by changing its properties as shown in Figure 2.6-3.
