Howard Gardner developed the theory of multiple intelligences which identifies eight different types of intelligence: linguistic, logical-mathematical, spatial, bodily-kinesthetic, musical, interpersonal, intrapersonal, and naturalist. The theory emerged from cognitive research showing students learn in different ways. Gardner identified these eight intelligences based on a person's sensitivity to different types of information and ways of processing information. The theory suggests teachers should incorporate methods that appeal to different types of intelligence to help students learn effectively.
