Imagine a math problem that consists in doing all sum operations you can in 2 minutes.
And then imagine these are the correct operations each student has done (each list entry represents a different student, it is ordered to keep it simple):
- 4 correct
- 7 correct
- 10 correct
- 11 correct
- 12 correct
- 12 correct
- 15 correct
- 15 correct
- 17 correct
- 22 correct
One way of evaluating it would be based on the overall students performance (maybe < 10 not passed, > 16 excellent
). But I don't see fair evaluating a student based on another student performance.
Another way I though would be to set each "milestone" myself. For example > 6 passed, > 18 excellent
but I was not the test author and students didn't know about that "milestones".
So, do you have any idea of what could be a fair option to evaluate students in an exercise of this kind? (It is a real case.)
Thanks!
