Drop Lowest Score

Case Study

Julie has four quizzes in her course, each worth 10 points.  She wants to drop the lowest score of the four quizzes.

NOTE: In a real course, there are many graded items. However, in order to clearly show the effect in the Grade Center, only four scores will be used.

When each quiz is deployed, a column in the Grade Center is automatically generated.

After students complete the quizzes, the instructor may 1) review the scores, manually determine the lowest, then Exempt that score. OR, 2) the instructor may set up a calculated column to automatically remove the lowest score. Both methods are explained in the following links.

When using the calculated column method there are two different types of calculated columns that can be used. The first type is referred to as the Total calculated column and allows the instructor to work with a final score (points) within the Grade Center. The second type is referred to as the Weighted Total calculated column and allows the instructor to work with a weighted final score (percentages) within the Grade Center.

The manual method is simple and direct but requires instructor involvement.

The automatic method requires several extra steps. But once it is setup, no further instructor involvement is necessary. The automatic method also has the advantage that when the course material is copied into another course shell, no further setup is needed.
