The Percentage-Based System uses a 100% scale to grade student performance. Each assignment is assigned 100%; individual assignments are grouped into categories, which are then assigned a different percentage or weight to calculate the final course grade. The sum of all the categories is 100.
How to Create an Assessment Schema Using the Percentage-Based Grade System?
Create Individual Assignments
Create individual assignments for the entire course and assign the maximum value for each 100%. In other words, a student can get a maximum of 100% for each assignment.
Determine the Assessment Categories
Determine the assignment categories (e.g., homework, midterm, presentations, etc.) and group individual assignments into each category. For example, ten individual homework short paper assignments can be included in the homework category. Consider using the Backward Design framework in this step.
Align Categories With Learning Objectives
Align assessment categories with the course learning objectives to determine which assessment category will be assigned a higher point value (high-stakes) and which category will have a lower point value (low stakes). For example, a midterm assignment is usually considered high-stakes, and a discussion board post can be regarded as a low-stakes assignment.
Assign a Percentage to Each Category
In this step, we are calculating the final course grade using the Weighted Total System. Consider Bloom’s Taxonomy to determine assignment categories deserve a higher percentage in calculating the Weighted Total.
