More correct answers with explanations than with a right-or-wrong mark
Medical students answered correctly more often with explanations (56% and 59%) than with a mark (51%). With new questions, neither explanation was better.
The study, in plain language
After a multiple-choice question, feedback can indicate whether the answer was right or wrong and also explain why. The team compared three forms of feedback with medical students: a correct-or-incorrect mark, an explanation of the answer, and an explanation of the concept, each for different questions.
Both explanations led to more correct answers than the mark, with small-to-moderate differences. When transfer to new questions was assessed, no advantage was detected for explaining the answer versus the concept. One week later, students took tests on the same content again.
The key idea
Explanations led to more correct answers than a right-or-wrong mark, and neither explanation stood out on new questions.

Beyond right or wrong: More effective feedback for formative multiple-choice tests
