One of the most common and widely-used categorizations of the various types of learning styles is Neil Fleming's VARK model (sometimes VAK) which expanded upon earlier Neuro-linguistic programming (VARK) models: (i) visual learners, (ii) auditory learners and (iii) kinesthetic learners or tactile learners. Fleming claimed that visual learners have a preference for seeing (think in pictures; visual aids such as overhead slides, diagrams, handouts, etc.). Auditory learners best learn through listening (lectures, discussions, tapes, etc.). Tactile/kinesthetic learners prefer to learn via experience—moving, touching, and doing (active exploration of the world; science projects; experiments, etc.). Its use in pedagogy allows teachers to prepare classes that address each of these areas. Students can also use the model to identify their preferred learning style and maximize their educational experience by focusing on what benefits them the most.
