Concept:Child-centered education focuses on the child's needs, interests, and active participation, with the teacher acting as a facilitator. Explanation:In a child-centered classroom, the teacher supports learning by giving timely feedback. This helps students understand their mistakes and improve. Option A is correct because feedback encourages growth and builds confidence. Options B, C, and D discourage questions, create fear, or promote unhealthy competition. These are not child-centered practices. Instead, they go against the child's natural development and freedom to learn. Therefore, providing timely feedback is the key to creating a child-centered classroom. Answer:Option A: Providing timely feedback to the learners about their performance.
