Howard Gardner's theory of multiple intelligences proposes that there are nine different types of intelligence rather than a single general intelligence. The nine intelligences are linguistic, logical-mathematical, spatial, bodily-kinesthetic, musical, interpersonal, intrapersonal, naturalist, and existential. Gardner argues that assessments should evaluate individuals' different cognitive strengths across multiple intelligences rather than focusing solely on linguistic and logical skills. Educators can apply the theory by developing curriculum that integrates and assesses students' abilities through multiple intelligences.
