Concept:A good evaluation system goes beyond mere grading; it should be a constructive tool that identifies learning gaps and enhances both student performance and teaching effectiveness.Explanation:Evaluation in education is a systematic process of assessing student learning against set standards. It involves collecting data through observation, documentation, and measurement, and then making judgments about the extent and quality of learning. An effective evaluation must be impartial, reliable, and useful. It should not cause stress or anxiety, nor should it only label students as passed or failed.

Additionally, it gives teachers insights into the effectiveness of their instructional methods, allowing them to refine and improve the teaching-learning process.Answer:Option D is correct: provides feedback to students and improves teaching-learning process.
