This question relates to my attempt at adaptive testing (https://moodle.org/mod/forum/discuss.php?d=215671), but it's strictly about grading.
I have created a course named Placement/Diagnostic Test, which consists of these quizzes:
There are 10 questions in each quiz.
Now, my aim is to reflect the level of difficulty in the overall mark a student gets in the whole test (technically - a course in moodle).
For example, all 'orange' quizzes are of medium difficulty, all 'purple' quizzes are a bit easier than the orange ones. How should I arrange the marking system to reflect that?Which one is a better idea:
- assigning different marks for separate questions in these quizzes? For example, each question in 'orange' quizzes will have a default mark = 5, and each question in 'purple' quizzes will have a default mark = 4, etc. It would mean I would have marks ranging from 1 to 9, a different one for each quiz colour group.
- using weighted means? If yes, then technically I don't know how to do it - I've read the moodle docs, I can understand that I should create grade categories (so it could be 'orange', 'purple', etc. in my case, right?). But when I tried to create a category with 'weighted means' option I couldn't even see the box for assigning 'weight' to it - the one that is shown in the moodle tutorial.
Can anyone help?
