Plain English Meaning
It is a way of describing the five main ways people learn: by seeing, hearing, reading and writing, doing, and touching. Good instructors try to teach using more than one of these channels so the lesson sticks for every student.
Full Definition
VARKT is a learning-styles model used in aviation instruction that identifies five sensory channels through which students take in and process information: Visual (seeing), Aural (hearing), Read/write (reading and writing text), Kinesthetic (whole-body movement and doing), and Tactile (touch and hands-on manipulation). Instructors use it to recognize that learners differ in which channels they rely on most, and to design lessons that present material through more than one channel so understanding is reinforced.
Context Anchor
Seen in aviation instructor training when discussing how to present a lesson so different students can understand it.
Derivation
An formed from the first letter of each learning channel: Visual, Aural, Read/write, Kinesthetic, Tactile. It is an extension of the older model, with Tactile added to separate hands-on touch from whole-body movement.
