Multiple choice is robust and easy to implement but not pedagogically ideal. It allows objective and reliable marking. However it provides trivial distractors that may engender misconceptions. On the other hand, open questions are pedaogically preferable but it is difficult to provide robust and valid marking. Open questions can also appear intimidating for learners.
With confidence-based marking, the student selects both their answer and their level of confidence or certainty. Then they get full marks for a confident correct answer fewer marks for a less-confident correct answer, and incur a penalty for being definite about a wrong answer.
