( |
array |
$grades | ) |
|
|
protected |
Calculates the aggregated grade given by the reviewer.
- Parameters
-
- Return values
-
| float|null | Raw grade (0.00000 to 100.00000) for submission as suggested by the peer |
◆ delete_dimensions()
| workshop_numerrors_strategy::delete_dimensions |
( |
array |
$ids | ) |
|
|
protected |
Deletes dimensions and removes embedded media from its descriptions.
todo we may check that there are no assessments done using these dimensions and probably remove them
- Parameters
-

◆ errors_to_grade()
| workshop_numerrors_strategy::errors_to_grade |
( |
|
$numerrors | ) |
|
|
protected |
Returns a grade 0.00000 to 100.00000 for the given number of errors.
This is where we use the mapping table defined by the teacher. If a grade for the given number of errors (negative assertions) is not defined, the most recently defined one is used. Example of the defined mapping: Number of errors | Grade 0 | 100% (always) 1 | - (not defined) 2 | 80% 3 | 60% 4 | - 5 | 30% 6 | 0% With this mapping, one error is mapped to 100% grade and 4 errors is mapped to 60%.
