The Canvas Quiz tool is one of my favorite elements in Canvas. However, 95% of the time I don't want to use it for quizzes or tests. Instead, I use it as an interactive learning activity.
For example, in the "quiz instruction" area, I may put a little content or context. Then, when the student clicks on "Take the Quiz," the first question may have them do some sort of activity or ask a question that they respond to such as typing out a solution, etc. Then in the next question, I may provide feedback, etc. In short, the Canvas quiz tool is great for creating learning and feedback cycles.
There is one problem, it is called a quiz.
I would love it if Canvas offered the flexibility to rename certain buttons and elements within a quiz so that the quiz tool can serve as both a quiz/test function and also a platform for creating engaging learning activities.
