I am almost painfully aware of the importance of examinations as a way to create emotionally important memory-recall events, and therefore their vital importance in learning itself. Within the examination itself, however, I usually place the questions in an order that optimizes page-layout; I want to give the students enough space, but otherwise use the fewest pages possible.
However, it occurs to me that this may not be optimal. Is there any research (or does anyone have experience) that supports the idea that the order of question on an examination can impact pedagogic efficacy?
