Gardner rejected the concept of intelligence as a single general ability, often measured as IQ in various psychometric tests, and proposed that there are multiple, interacting intelligences (modalities) which better represent the spectrum of human cognitive abilities. These intelligences are eight in number, namely:

While the focus of most traditional educational and pedagogy practices is on verbal-linguistic and logical-mathematical intelligences, other intelligences are often much less explored as a medium of learning. Design of artefacts, applications and activities for learning should use all of these modalities as multiple entry points to introduce concepts. Increasing the ways that work for different children based on their unique profiles of multiple intelligences would allow better understanding as well as higher number of children who would understand these concepts. There are useful free online tools which assess an individual’s strengths and weaknesses for each of the intelligences, such as:
