Written by internationally renowned educator and researcher Robert Sternberg, this text is based on Sternberg's research-supported theory that students need to develop analytical, creative, and practical thinking abilities in order to acquire successful intelligence. It addresses the notion that many educational programs seem to develop people's intelligence in only one area analytical and that students need all three to be successful in life. Useful as a reference or primer, all teachers of all grade levels and subject areas will benefit from these proven teaching and assessment techniques to promote development of all three abilities.
