Academic Motivation Scale:
The Academic Motivation Scale is a measure of intrinsic, extrinsic and amotivation in education developed by Vallerand and colleagues at the University of Quebec in Montreal, Canada. Originally developed in French as the Echelle de Motivation en Education (EME), it is based on the principles of self-determination theory and comprises 28 questions aimed at assessing seven subscales of motivation: three intrinsic (to know, to accomplish things and to experience stimulation); three extrinsic (external, introjected and identiified regulation); and amotivation (lack of motivation).
