Scales are a way of evaluating or rating a learners' performance. Totara offers a standard set of numeric scales. It is also possible to create custom scales which can be available on the site. For example, you can give the trainer a word or small phrase as a way of rating or giving a learner feedback.
Scales may be used in Forums, Glossaries and Assignments for rating and/or grading a learner's activity.
Standard scales: Totara includes different numeric scales which can not be edited, and one non-numeric example.
Numeric: Totara includes numeric scales that range from a maximum of 100 to a minimum of 1. For example, selecting a scale of 10, will allow a rating on a scale between 10 and 1. Numeric scales can be calculated as a grade.
Included non numeric scales: Included in the standard Totara install is a scale called "Separate and Connected ways of knowing". This has 3 elements: "Mostly Separate Knowing", "Separate and Connected", "Mostly Connected Knowing". These phrases relate to a theory about how people approach the world. In edit mode, the trainer or administrator can see the scale description which explains the use of this interesting rating system.
New scales can be created by trainers with editing rights or by administrators or by any user with the manage scales role capability . Scales can be edited in the Gradebook Menu Scales. The process is similar for making a new scale for either a course or site.
Creating scales that are available in every course is similar to creating one for a single course. The site administrator will find a Scales link in the site administration block under Grades. It will list the scales available on the site, except the standard numeric sales.
First the trainer needs to assign a specific scale to the activity using a drop down menu in the activities setting. Then the trainer and/or trainees can rate an activity element (for example, a post in a forum) with the pre-defined scale.
If a scale has not yet been used, you will see an edit, move, and delete icon in the edit column.
Once a scale is used for an activity, it is no longer possible to move or delete it, and you can only edit the scale name and description.
Totara uses the last entry to determine the number of points in the scale for computing percentages. For example, if your scale is 0,5,6,7,8,9,10 then Totara will use a 0-6 or 1-7 point scale depending on your chosen aggregation method.
Either way, the numbers you enter for your scale are NOT calculated as entered, the system calculates the number of non-zero entries and then creates a scale from 0 to the total number of entries (n) with their values calculates as 0/n, 1/n, 2/n, 3/n....
'Letters' allows you to associate a letter grade with a percentage range.
