One of several reasons why Canvas is such an inferior LMS to Blackboard is the almost complete unwillingness of the developers to keep improving their product.
Case in point: Fill-in multiple blanks questions.
In Blackboard, you can specify whether you want the answer to be matched as:
In Canvas, not a chance!
So, Imagine that an instructor wants to create a question about a confidence interval in a quiz. The first idea is to create a multiple-numerical answers question, but that would be too easy, right? Of course, there is no such question type available (to be fair, neither there is in Blackboard.)
So, the next best thing is to set it up as a fill-in multiple blanks question. Only, Canvas makes it soooo much harder than Blackboard, because unless you are incredibly strict about the allowed correct answers, you will always find some student who manages to mess it up in some unexpected way and still expect credit for it. Then, good luck with 'fudge'.
Fudge! Really, Canvas?
At least Blackboard allows for correct answers so long as they contain a certain string of characters, which works great for rounding issues.
But Canvas? Maybe we will get an improvement when hell freezes over because all the developers have managed so far is to come up with the brilliant idea of New Quizzes, which is a brand new exercise in the logic of regress to a worse version than it was with Classic Quizzes.
I can't retire fast enough, apparently.
Please pardon me if I am off target, but I ask confidence interval questions on tests by separately asking for the lower and upper bound and using a numeric question type. I simply separately ask for the lower bound and the upper bound in two consecutive questions. The screenshot is for the lower bound, question number seven asks for the upper bound.
