How Do I Weight Grades?
« on: January 16, 2017, 02:31:25 PM »
There are three levels of weighting possible in simplegradebook for percentage assignments.

1. Weighting Assignments

Assignments can be weighted against each other using either the total points method or the equal points method.  The weightings are entered when you create the assignment.  They can also be changed after it was created.

For the total points method, just make the Points for your assignment equal to the number of points that you want it to be worth in your class:



Notice that when you click on Total Points, the field is automatically filled in with the value you entered in the Points field.  Your assignments will be weighted based on the number of points you entered for them.  So, if you have an assignment worth 30 points, and the total number of points for all assignments is 1200, that assignment will be worth 30/1200 or 2.5% of the total.  Note that the Scale Factor will automatically be set to 1 - if you want an assignment worth double points, just set the Scale Factor to 2, or 3 as appropriate.

For the equal points method, enter the Points the assignment is out of, then set the Total Points for all your assignments equal to some value like 100. 



The Scale Factor will be automatically adjusted to make all the assignments worth the same.  If you want an assignment to be worth double, set the Total Points for that assignment to 200, or 300.

2. Weighting Categories

When Categories are entered for assignments, a weighting percentage can be entered for each category if the class is a percentage or letter grade class. The weightings are entered by clicking the Class Settings button beside the class.



In simplegradebook, category weightings do not have to add up to 100, but doing so makes things less confusing for parents and students!  In this case, the category weighting percentage is converted to a decimal, and the total points in that category is multiple by this decimal.  For example, if you enter 30% in the category weighting, the total points a student earns in that category will be multiplied by 0.30 when determining the overall achievement.



3. Weighting Terms

A weighting percentage can also be applied to a Term. 



Once again, Term weights do not have to add up to 100%, but it makes the most sense to parents and students if they do.  For example, is common to have Term 1 - 40%, Term 2 - 40%, Final Exam - 20%.  Terms can also be used for units of study, such as Trigonometry - 20%, Algebra - 30%, Shape and Space - 30%.  Term weights are incorporated into the overall mark the same way that Categories are.
