- My Default Gradebook
- Category 1 (60% of course grade)
- Item 1.1 (25 points) (25% of category, 15% of gradebook)
- Item 1.2 (25 points) (25% of category, 15% of gradebook)
- Item 1.3 (25 points) (25% of category, 15% of gradebook)
- Item 1.4 (25 points) (25% of category, 15% of gradebook)
- Extra Credit Item (10 points) (10% of category, 6% of gradebook)
- Category 2 (40% of course grade)
- Item 2.1 (15 points) (40% of category, 16% of gradebook)
- Item 2.2 (15 points) (30% of category, 12% of gradebook)
- Item 2.3 (15 points) (30% of category, 12% of gradebook)
- Category 1 (60% of course grade)
Weight based calculations are used whenever a gradebook is in "Weighted Categories" mode. In this
case the instructor must lay out the desired weighting of each category and each item within those categories.
These weights are effectively a best case scenario, in which a given student has scores assigned for every item. If a score has not been assigned for an item or if the student has been excused from that item or if that item has been dropped as a lowest score within a category then that item will not be included in the calculation for that student and the weights will be proportionally modified based on the items that are scored.
So in the table below, the hyphen indicates unscored items, and otherwise a weight is provided to indicate the course grade weight that item will contribute:
Student | Item 1.1 | Item 1.2 | Item 1.3 | Item 1.4 | Extra Credit Item | Item 2.1 | Item 2.2 | Item 2.3 |
|---|---|---|---|---|---|---|---|---|
Joe | 15% | 15% | 15% | 15% | 6% | 16% | 12% | 12% |
Melody | 20% | 20% | 20% | - | 6% | - | 20% | 20% |
Francis | 60% | - | - | - | 6% | 40% | - | - |
Roderick | 100% | - | - | - | 6% | - | - | - |
That is, Joe has a score for all items, and so receives the default weights for those scores. Melody has one item in Category 1 ungraded, and so each of the other three items in that category increase their weight proportionally to 33.33% of the category or 20% of the course grade; she also is missing a score for Item 2.1, so Item 2.2 and 2.3 each increase to 50% of the category and 20% of the course grade. In Francis' case, since she has only one item in each category graded, they each make up the full category weight, 60% and 40% respectively. Roderick, finally, has only one item graded and so that item's score is 100% of his course grade.
This is an essential strategy in order to cleanly project grades throughout the quarter/semester/trimester, so the instructor can see how well his or her students are doing based on the items that have been graded, even before all the scores are in.
