How can a human teacher see a child’s mistake?

Correct answer: A learning opportunity

The governing concept is constructive, learner-centred teaching. A human teacher can treat a mistake as evidence of what the child has not yet understood, then use it to give correction, practice, encouragement, or a clearer explanation. Thus, option A is correct: a mistake can become a learning opportunity. It need not be treated as a permanent failure or a crime. Options B, C, and D are unsuitable because they turn an ordinary part of learning into punishment or an unrelated contest. Human judgment allows the teacher to respond to the child’s actual need.
