I think part of the reason that a lot of student evaluation is now in the form of tests (multiple choice I assume) is because they are relatively easy and quick to mark. Evaluating a piece of design or art work, or asking to write creative prose, or showing all the working out for a lengthy mathematical problem requires significantly more time and energy than feeding a test through a computer.
