Howard Gardner, a professor of education at Harvard University, is renowned for laying out the theory of multiple intelligences (MI), which argues that the customary views of intelligence are too narrow. Whilst traditional IQ tests measure verbal and mathematical skills, MI theory maintains that humans have multiple intelligences.
Included in these are spatial, musical, bodily-kinesthetic (movement), interpersonal skills, intrapersonal and naturalist (understanding and classifying objects in nature). So whilst some may not be to 'hot' on mathematics they may be great musicians or wonderful at understanding human beings.
A kid who struggles with conventional school work and ends up with poor grades may go on to be very successful in the 'real world' which requires and values a huge range of talents.
So where do you think your strength is intellectually speaking?
