In which situation has the student turned self-reflection into corrective action instead of only thinking?

Correct answer: Writing the cause of the mistake and adding that part to practice for the next three days

Reflection becomes corrective when it produces a specific change in future behavior. Writing the cause of the mistake identifies what needs attention, and adding that area to practice for three days creates a concrete opportunity to test improvement. Feeling sad, hiding the error, or blaming the paper may not reveal what the student can change or do next.
