Within the PolyLearn (Moodle 3.1) Gradebook, faculty can use it three different ways. The aggregation is very useful for weighted if used correctly. Below are some examples of how a gradebook can be setup based on the faculty members needs to display total, weight by category, or weight by category and item.
Table of Contents
Go to the Course Category total and click on the Edit Menu,, then click on the Edit settings link.
The Aggregation is defaulted to Natural. Natural will allow you to set the Gradebook to "Sum of Grades" or "Points Total".
The Natural aggregation is unweighted when the boxes are not checked. Do not check the Weights boxes if you want Sum of Grades.
Notice the bottom value is 435 points under Max grades.
If you want to weight your Gradebook, you have three aggregation types: Natural, Simple weighted mean of grades and Weighted mean of grades.
If you use the Natural aggregation, you will not see the total Weights, just Max grade (total points).
For example if your course had items weighted by categories (Homework 25%, Quizzes 25% Exams 40%, and Participation 10%), then this is the setup for your course. The weighted categories (25% + 25% + 40% + 10%) equal 100%. 100% will not show up at the bottom of the Weights column. If it doesn't equal 100%, the values you enter will be changed by PolyLearn to equal 100% for you. ( see video example)
NOTE: This is an example of a Gradebook aggregation using Natural, then checking the Category Weight box on the right and type in the weighted % value.
Please see the tutorials on Weighting Grades by Category.
- In class graded items can be create by clicking on the Add grade item button.
- Categories are created by clicking on the Add category button. Items can be placed into categories by clicking the box in the Select column and then choosing the category in the Move selected items to list.
- When finished adding items, make sure to Save changes.
You may want to use Simple weighted mean of grade instead of Natural aggregation if you want your Gradebook to have 100% at the bottom under Max grade.
This example course is called "Gradebook". On the right of the course name, click on the Edit Action and choose Simple Weighted Mean of grades for the aggregation. For the Maximum Grade value, type 100 (this will be the 100%).
Add the other categories and set the aggregation to Simple weighted mean of grades. Use the Maximum Grade value for those % weights. You need to verify that all your weighted equal 100%. PolyLearn will not fix the value for this aggregation.
The only time you would want to use Weighted mean of grades is if you have items within one category that require different weighted.
For example the Exams category has three items (2 Midterms & 1 Final). The Final is wighted higher than the midterms.
