There are three main types of learning styles: visual, auditory, and tactile/kinesthetic. Visual learners learn best through seeing, auditory learners through listening, and tactile/kinesthetic learners through moving, doing, and touching. Howard Gardner proposed multiple intelligences which include linguistic, logical-mathematical, spatial, bodily-kinesthetic, musical, interpersonal, intrapersonal, and naturalist intelligences. Brain-based learning principles indicate that memories are strengthened through frequency, intensity and practice, and that emotions, meaning making, and attentional limitations impact the learning process.
