Bug?: Bad equation rendering in feedback of Blackboard created quizes #1375

Open nelis73 opened 5 years ago

nelis73 commented 5 years ago

Summary:

When importing quizzes originally produced in Blackboard into Canvas a flaw is encountered: Equations and other rich material are not propperly rendered within the feedback environment.

Steps to reproduce:

  1. Create quiz in Blackboard (create equation in feedback environment).
  2. Export quiz as Blackboard export file (zip).
  3. Import quiz into Canvas.
  4. Look at feedback.

Expected behavior:

Equation and other ritch material such as tables and plots should be properly rendered.

Actual behavior:

  1. Rich material in quiz_comment environment is messed up.
  2. Analysis: During Canvas import, feedback from Blackboard quiz is treated differently than content from other environments, such as that of the item body. It seems not to be evaluated. For example, plots are not imported in Canvas data base (whereas for other parts, such as the item body, they are).
  3. As a result the quiz_comment environment is messed up. It shows only parts of the original equations and refers to the original links in the Blackboard data base

Additional notes:

See my question on the Canvas community page for an analysis of the html/xml code encountered in the different environments: bug?
