Gardner argues that traditional views of intelligence are too narrow and that there are multiple intelligences. He identifies eight criteria for what counts as an intelligence and lists eight intelligences: linguistic, logical-mathematical, spatial, bodily-kinesthetic, musical, interpersonal, intrapersonal, and naturalistic. Gardner acknowledges limitations of his theory and argues that intelligences are developed through biological and experiential factors within a cultural context. The document discusses applying multiple intelligences theory to education by incorporating varied forms of assessment beyond standardized testing.
