How scores are calculated on ExpertTrack courses
Courses that form part of an ExpertTrack use the 'weighted step scores' calculation.
All steps that are able to generate a score* are assigned relative score weightings as part of the course design process. These weightings are then used to calculate the overall course score as a weighted average of the percentage scores from the steps.
For example, suppose a course contains two tests, each with a score weighting of one, and a peer graded assignment with a score weighting of eight. The overall course score for a learner who scored 50% and 60% for the tests, and 70% for the assignment would be:
Learners can see how much each step contributes to their overall score on the step itself and on the run progress page.
Learners are not awarded an overall course score until they have received a score for all of the scored elements. If any scores are missing, the run progress page shows what needs to happen for those scores to become available.
Configuring score weightings
Score weightings can be edited by clicking Score Weightings on the Course Content tab.
The score weightings page contains an editable weighting field for each scored step in the course. The equivalent percentage contribution is also displayed alongside each weighting.
All new tests and peer graded assignments are given a score weighting of one by default. This means that, unless the weightings are modified, each assessment is worth an equal proportion of the overall course score (for example, if there are four assessments in the course, by default each will contribute 25% towards the overall score).
Each weighting must be a whole number. Steps that have zero weighting don't contribute towards the overall course score.
How scores are calculated on non-ExpertTrack courses
Courses that are not part of an ExpertTrack use the 'combined test scores' calculation.
With this calculation, the overall course score is the total number of points awarded across all tests as a percentage of the total number of points available.
For example, suppose a course contains two tests, one with five questions (max score 15) and the other with ten questions (max score 30). The overall course score for a learner who scored 12 and 23 points in those tests respectively would be:
With this calculation, only scores from tests can contribute to the overall course score. The contribution each test makes to the overall course score is proportional to the number of questions it contains and so, to avoid giving the impression that some questions contribute more to the overall course score than others, step weightings are not displayed on courses that use this calculation.
