Feedback as teaching improvement tool – UGC NET Question

Using performance information to adjust later teaching is the feedback function—closing the loop between assessment and improved instruction.

Option A:
Reinforcement is a consequence that strengthens behaviour (e.g., praise), not necessarily instructional modification.

Option B:
Diagnosis identifies causes of difficulties; related but narrower than general “performance info used to modify instruction.”

Option C:
Grading summarises performance with scores/marks, not necessarily used to change teaching.

Option D:
Feedback is information used to improve future teaching/learning actions, exactly as described.
