J.P. Guilford proposed a detailed model of intelligence that includes three dimensions: contents, operations, and products, ultimately comprising 150 specific factors. He introduced the concepts of divergent and convergent thinking, emphasizing the importance of creativity in problem-solving through fluency, flexibility, originality, and elaboration. The educational implications of his work suggest that intelligence is not fixed, can be learned, and that diverse methods should be used to accommodate different students' learning abilities.
