Concept:Learning is best fostered when new information is linked to the learner’s existing knowledge. This builds on the principle of moving from the known to the unknown.Explanation:Effective learning happens when children can connect new ideas to what they already understand. Drills, punishment, or long study hours create stress and do not promote lasting change. Connecting new material to prior knowledge helps the child relate, remember, and apply the information in real situations. For example, when a teacher explains a new math concept using everyday examples the child knows, learning becomes easier and more meaningful. This approach uses the natural process of building on previous experiences. Feedback and practice are also important, but the key is making the new content familiar through prior knowledge. Thus, among the given options, only option D aligns with this proven educational principle.Answer:D. connecting new materials with something the child already knows.
