To make test security and validity better, I'd like to have it close out the test/quiz if they navigate out of the window they are using to take the test. It might be nice to have that available on assessments as well, but I thought perhaps they may be less formal or for review.
As it is, when giving a test to a 1:1 school student, I have no way of knowing if they are looking up answers. Though knowing where to go to find answers is a good skill to have, it doesn't belong in a testing situation for knowledge of a topic. Because of this, I can't use the test/quiz option for its intended purpose. I still have to make multiple forms of paper tests to ensure I'm getting what they have learned as a result.
