Typical example of college writing I see

117. It is much more prevalent, starting when schools went online during COVID.

My own practices changed as a teacher, because I believe online closed book testing is inherently unfair. Even when test monitoring is available, the tools each student has for taking the test (quality/reliability of computer, compatibility of the computer with the monitoring equipment, space conducive for test taking (e.g. rich child with a private room v. a poor child from a large family where several children are sharing the bedroom as a few examples) means that some people will have an advantage over others - before even taking cheating into account.

And, as an undergrad student (as I have been for the past 3 years), I've had one class which used closed book exams. All of the others were either completely untimed, open book - OR - timed, and relied on the time crunch to sort those who knew the content from those who didn't.

There are very few professions where one is expected to perform without being able to access resources - so the open book test models what students will encounter once they graduate - and don't end up being a sorting tool for who is better at rote memorization than their peers. (A pet peeve of mine, since I've always had to figure out work-arounds to get through exams because logic, rather than memory, is how my brain works.)
