GB2 Grade Calculations
The calculations for the new gradebook have two main modes:
- points-based calculations : in which the ratio of an item's max points versus the total points possible for all items scored is used to establish the item's 'weight' within the gradebook
- weight-based calculations : in which the product of two assigned weights at the category and item levels is used to establish the item's 'weight' within the gradebook
Points Based Calculations
There are two cases for points based calculations, but the distinctions between the two are very slight. Whenever the 'organization' of the gradebook is set to "No Categories" or "Categories", points-based calculations will be used, independent of whether the "grade type" is set to "points" or "percentages". In setting up the gradebook, an instructor must provide a maximum number of points per item, or if one is not entered, a default value of 100 will be used.
So, in "No Categories" mode, we might create the following gradebook:
- My Default Gradebook
- Item 1 (25 points)
- Item 2 (25 points)
- Item 3 (25 points)
- Item 4 (25 points)
- Extra Credit Item (10 points)
This gradebook would have a total possible non-extra-credit point value of 100, with 10 extra credit points possible.
