When creating a formula question for math or science (I teach physics) I would like to allow multiple attempts per problem. I don't think this is a feature in Canvas but here is why it is needed. A good learning environment allows for a learner to attempt a problem and if wrong then reevaluate to try to identify what they did wrong and fix it. This process of corrective self learning is extremely valuable to problem solving skills.
So in short 1) Add multiple attempts per problem, not just quiz; and 2) Allow unique feedback per attempt which allows the teacher to give tiered feedback trying to help guide the learner if they do need multiple attempts.
By the way, Moodle has these features but my district is going with Canvas.
The idea is if the student solves the problem and gets it wrong they don't have to do a whole other quiz to work on that learning objective. The teacher should be able to see how many tries it takes for a student to get a problem. If after the allowed amount of tries the student is still wrong then they can retake that quiz if so desired. Also, after each incorrect answer a unique feedback should be able to be provided. This allows the teacher to give increasingly helpful hints as the student struggles.
Welcome
Hi Alex Moody
Welcome to the Canvas Community. You bring up a very interesting idea that I cannot exactly answer, but for which I can start pointing out other resources within this great Community. First, Canvas is currently supporting a legacy version of quizzes and a newer version called Quizzes.Next. If you're not sure which one your institution is using, here are a few video overviews where you will be able to tell rather quickly:
Because of this, no more development is taking place on the legacy version of quizzes (the first link); all future development is being concentrated on Quizzes.Next. I encourage to join the following group within this community to keep an eye on developments for Quizzes.Next: New Quizzes User Group . To join, follow that link and at the upper-right of the screen, click the Action drop-down menu and then Join Group.
Finally, you can vote "up" Feature Ideas or create your own. The one idea that I could find that somewhat matches your idea--though I admit not exactly--is this one: New Quizzes: Carry Forward Correct Answers on Quiz Multiple Attempts . It is still available for voting and I encourage you to vote it up and comment on it. If you find your idea should be a separate one, you can create your own Feature Idea by following these instructions: How do I create a new feature idea in the Canvas Community?
I hope this helps a bit, Alex, even if it's not a solution to your issue. That said, we're always here to assist you as you're learning the ins and outs of Canvas.
