Do students do better when they write exams faster (or slower)?


Regular contributor Chris Buddle examines the relationship between how quickly (or slowly) students complete exams and their performance. He demonstrates some very interesting results.

From Chris’ post:

As I was grading my final exams last week, I wondered about ‘quantity’ of answers to written questions as opposed to ‘quality’ of the answer: in other words, some students write a lot of stuff for an answer, but could have received full points on a question without filling a page with tiny handwriting. Here’s what I tweeted about this.

The students that fill the page certainly take longer to complete an examination, and this reminded me of a little project I did many years ago* about the speed at which students write their exams relative to the grade they received on that exam. For one of my larger undergraduate classes the final exam is meant to be about a two hour exam, but some students finish in just over an hour, and some students wait until we take the exam from them at the end of the three hour exam period.

One year I tracked the order that students forwarded me their exams and after the course was over I plotted their grade on that exam relative to the time it took them to complete the exam**. I’ve always wondered whether or not students who finish quickly are the ones that really know the material, or whether the ones who take the longest are so careful to check and re-check everything that they tend to do better than their peers. Here are the results:
