Question blocks are unique because they have defined correct and incorrect answers. These answers are automatically and immediately marked by the tool. If your learning object is situated within an LMS, you will be able to capture your learner's answers.
Feedback can be an important growth moment for your learners. If they have submitted an incorrect answer, feedback presents an opportunity to correct misunderstandings. There's also a chance that the learner was unsure of the answer and took a lucky guess, or chose the correct answer for the wrong reason. While appearing correct, this learner also lacks a proper understanding of the concepts and it is equally important to take the opportunity to correct misunderstanding.
With this in mind, it is an excellent practice to use the feedback text to briefly reiterate the concept that underpins the question. This looks like addressing correct and incorrect answer options and describing why they were or were not correct. This allows an unsure learner to correct or confirm their understanding of the concept.
An example is provided below in the form of a multiple choice question. The correct answer to the question is 'Jumped'. Notice that the same feedback is given for both Correct and Incorrect answers to cover all the scenarios described at the top of the article. The feedback addresses each of the multiple choice answer options.
