Teachers should be able to add time to a timed quiz after the time is up. In a face to face class, if a student has been working diligently on a quiz or test and they ask to have additional time, I give it to them. If we are creating virtual environments that are as much like face-to-face classes as possible, we should be able to do the same. I set my time limit on quizzes for 30 minutes and on unit tests for 1 hour, both reflecting what a student would have in a face-to-face setting. If a student needs an extra 10 or 15 minutes, I should be able to give it to them with no problem. In addition, it should be quick and easy to do.
