Hello,
With respect to Canvas Quizzes, I really like using the multiple answer format in my University class. The problem is that I don't like the grading methodology. I understand the grading works as explained below. Here is an example: I give five possible answers. Two are correct answers. If a student chooses one correct answer and one wrong answer, then Canvas grades as follows:
1. Since there are two possible correct answers every answer is worth 0.5 points. The student gets 0.5 points for every correct answer and has 0.5 points deducted for every wrong answer.
2. So in this case, the student's grade is 0.5-0.5=0 points.
I would argue that the student got the question half right. If it were up to me, I would give this student half credit (0.5 points) for this question. I would appreciate an option allowing the instructor to choose this grading option.
To elaborate, this is how I think this alternative grading option should work using the same example from above:
Recall there are five possible answers and two are correct answers. If a student chooses one correct answer and one wrong answer, then Canvas grade should be as follows:
1. Since there are two possible correct answers and student chose two answers, then student gets credit for every correct answer: so student gets 0.5 points for the correct answer but doesn't get penalized for the wrong answer.
2. So in this case, the student's grade is 0.5-0=0.5 points.
3. However, it is important to penalize the student for too many incorrect answers. So the methodology would need to provide that so long as the student only selected as many answers as there are correct answers (i.e. two in this case), then there would not be a penalty for the wrong answer. However, if the student selects more answers then there are correct answers (i.e. if the student chooses three answers in this example), then the student would get a point deduction as follows:
1. Student gets 0.5 points for the correct answer and no penalty for the first incorrect answer. But student gets a 0.5 point penalty for each additional answer beyond the number of correct answers. So a student that picks one correct answer and two incorrect answers in this case would get a grade of zero (0.5-0-0.5=0).
I would be happy to discuss this further with a member of your development team or product management team. I would be grateful for your consideration of this alternative grading approach.
Thanks very much,
