For some students it also can serve to mitigate exam shock (speaking to high school level anyway, which is my area). Finding a familiar, or even roughly familiar question can mean a nervous student has an entry point into the exam. I quite liked the article. It'd be interesting to see if the benefits persisted over multiple groups though. I tend to see engagement increase when rules are changed and students need to figure out how to address the problem in a new way, regardless of whether they are collaborating or not. (anecdotal evidence there only sorry ;P)
