The most effective way grading can be used as a learning tool is:
"By offering detailed feedback that helps students understand their strengths and areas for improvement."
This approach emphasizes the role of grading not just as a means to rank students, but as a constructive tool that provides insights into their learning process, encourages growth, and helps them build on their skills. Detailed feedback can guide students in their learning journey, making them more aware of how to enhance their performance and understand concepts more deeply.
