We are happy to announce that a bug in using Different Every Time randomization for assignments has been fixed.

Before today, if you delivered your assignments different every time to your students, viewing their responses was only meaningful for their last response. When All Responses were viewed, the questions contained incorrect randomizations.

This has been fixed. Viewing all responses now shows an accurate picture of the question as it looked to the student each time they submitted it. Please let us know if you see any problems.

Another bug that was fixed with Different Every Time was the way the randomization seeds were created. In some cases, the randomized values in the questions on each version of the assignment did not appear to be random. This occurred when the questions on the assignment had a similar structure.

Please note: The Different Every Time method of delivering assignments should only be used with Require Submission of Entire Assignment. It does not work with the submission of single questions. We apologize for not making this restriction apparent in the interface.
