Background
Scoring mechanisms offer a variety of ways to grade each item. collaborationQ provides three different scoring mechanisms:
- System score
- Recalculated score
- Minimum and maximum score
System score
This is the default scoring mechanism when you create a new question.
Example:
If you create a fill gaps question with 5 gaps, the system will automatically assign a score of 1 point to each gap. The total max score for the item will be 5.
If the participant correctly answers 3 out of 5 gaps, he will have a score of 3/5.
Recalculated score
If the recalculated scoring mechanism is set for a question, the score will be calculated following the default scoring mechanism, but it will be recalculated to the minimum and maximum score that have been entered.
Example:
Let us again take the same example of a fill gaps question with 5 gaps for which the default system scoring is: min score = 0; max score = 5.
The author selects the recalculated scoring mechanism for this item and changes the max score to 2.
If the participant correctly answers 3 out of 5 gaps, he will have a score of 1,2/2.
Formula for recalculated scoring
| For positive scores: | (Score/System max score ) * Recalculated max score |
| For negative scores: | (Score/System min score ) * Recalculated min score |
Example:
| System min score | System max score | Recalculated min score | Recalculated max score | System score | Recalculated score |
|---|---|---|---|---|---|
| -3 | 5 | -1 | 2 | 3/5 | 1,2/2 |
| -3 | 5 | -1 | 2 | -3/5 | -1/2 |
| -2 | 5 | 0 | 1 | 2/5 | 0,4/1 |
| -2 | 5 | 0 | 1 | -2/5 | 0/5 |
Minimum and maximum score
If the minimum and maximum scoring mechanism is set for a question, the participant can only obtain the system minimum or maximum score for the item, no intermediate score.
As an author you can set the minimum or maximum score in the Scoring tab of a question.
Example:
Let us take a fill gaps with 5 gaps for which the default system scoring is: min score = 0; max score = 5.
The author selects the min or max scoring mechanism for this item and changes the max score to 2.
The participant correctly answers 3 out of 5 gaps. As he or she did not answer everything correctly, he or she will have the minimum score of 0.
