This bulletin offers guidelines to help parents and teachers improve the thinking skills of gifted children. It stresses the importance of encouraging thinking through the use of evocative questions, distinguishes between and defines critical thinking and creative thinking, and offers suggested questions to prompt either creative/divergent thinking or critical/analytical thinking. The need to foster such traits as persistence, open-mindedness, rationality, flexibility, and intellectual honesty is also stressed. A home which fosters thinking skills is described as one in which the family works together to solve problems. Suggestions are also offered for fostering children's metacognitive skills by prompts and questions that help them to monitor and evaluate their own thinking. General guidelines for nurturing thinking as well as criteria for classroom thoughtfulness are listed. (DB)
