In group interactions, children with better memory also have greater social skills. From the researchers’ findings, preschool children with better memory do have an advantage. The teacher suspected that he was a “slow student.”Teachers might often categorize students with poor memory as slow learners. Especially given the low birthrate today, when all children are precious to their parents, teachers have an even greater responsibility. The classroom must be a friendly learning environment, not “killing fields” for students thought to be “slow.” This is the classroom management ability teachers must possess.
