What is the greatest benefit of a teacher marking and returning homework promptly?

Marking and returning homework promptly significantly benefits students' motivation to enhance their performance. When students receive timely feedback, they can understand their strengths and weaknesses concerning the concepts taught. This immediate recognition can encourage them to put forth greater effort in future assignments, leading to a continuous cycle of improvement.

Timeliness is crucial because it connects the feedback directly to the relevant content, making it more meaningful to the students. They can apply corrections and insights to their upcoming work, which fosters a sense of progress and achievement. The prompt return of homework not only reinforces learning but also shows students that their work is valued, thereby promoting a more engaged and proactive approach to their education.

The other options, while relevant to the educational process, do not capture the motivational aspect that directly impacts students’ performance in the same way.
