As assessment becomes more and more necessary and commonplace in online courses, the opportunity for students to explain themselves on why they selected an answer might be a good way to bridge the gap and promote both fairness and critical thinking. Tim Hunt of the Open University has introduced this as a Moodle concept in the Question Behavior addon, “Deferred Feedback with Explanation“.

This question behaviour is just like deferred feedback, but with an additional input box where students can give a reason why they gave the answer they did.

No attempt is made to automatically grade the explanation, nor is it required. However, it may be used in various ways, for example

1 The teacher may want to manually edit the grades where the student gave a wrong answer, to give partial credit if the student used the right method or approach.
2 The student might want to explain their thinking, so that later, when the results and feedback are revealed, they are reminded of what they were thinking at the time, and so can reflect more deeply.

  1. Thank you for highlighting this plugin. To give credit where it is due, I only got around to making it because Madhusudan Singh asked for it in the quiz forum recently.

    Mind you, I am pretty sure it had been talked about before once, and I had had the idea vaguely floating around in my head that it would be possible and might be useful. Still, it took a nudge to make me actually do it.
