Caching Issues for Updated Quizzes
Aug 29, 2015
I deliver quizzes through an LMS. I periodically make updates to the quizzes, including deleting old questions and adding new questions.
The issue I run into is that after uploading the updated quiz to the LMS any students who accessed the quiz prior to the update get some strange things happening when accessing the same quiz after the update has been made. They'll often end up getting stuck and not able to complete the quiz.
The problem is that their browser's have cached the old quiz and it conflicts with the updated quiz. We end up spending lots of time walking students through the steps for clearing their browsers' cache.
Is there some way to force the students' browsers to clear cache when launching an updated version of a quiz so that they won't get stuck? Is it possible for an LMS to clear a browser's cache in these instances?
Any ideas on how to get around this problem would be greatly appreciated.
