Feedback in systems approach – UGC NET Question

In the systems approach to teaching, feedback refers to information about the outputs—such as learner performance—that is fed back into the system to guide improvement. Teachers use test scores, observations and student comments as feedback to modify objectives, materials or strategies. This loop helps maintain or enhance the effectiveness of instruction. Therefore, the information about learner performance used to modify future teaching is called feedback.

Option A:
Input in a teaching system includes elements like student characteristics, resources and objectives that enter before instruction begins. While important, input does not describe information generated after instruction. Hence, it is not the term for performance information used to adjust future teaching.

Option B:
Throughput (or process) refers to the actual teaching–learning activities that transform inputs into outputs. It encompasses classroom interaction and instructional strategies. The stem, however, focuses on information used after observing outputs, which is different from throughput.

Option C:
Output denotes the results of the system, such as test scores, skills acquired or changed attitudes. Although feedback is based on outputs, the term “output” alone does not capture the idea of using this information to modify the system. Thus, it incompletely represents the concept described.

Option D:
Feedback is the flow of information from the output back to the system to indicate how well objectives are being met. In teaching, this includes exam results and other evidence of learning, which guide the teacher in revising plans and methods. Because the stem emphasizes using learner performance information to change future instruction, “feedback” is the correct term.
