Intrinsic motivation has a crucial role in students' learning and should therefore be taken into consideration in educational activities. In this study, the short scale of intrinsic motivation scale developed by Wilde et al. in 2009 was adapted to Turkish Culture. This is an intrinsic motivation scale, which is an adapted, time-economic version of the "Intrinsic Motivation Inventory" introduced by Deci and Ryan. The short scale has four factors, namely interest/enjoyment, perceived competence, perceived choice and pressure/tension with three items each. Data were collected from 230 high school students in two public high schools in Northwestern Turkey in order to analyze the scale's factorial and construct validity. The linguistic equivalence step was carried out by consulting expert opinion because intrinsic motivation differs from one context to another. Results from a confirmatory factor analysis, construct validity and tests for reliability showed that its version adapted to Turkish is a good and time-saving assessment tool for measuring intrinsic motivation during lessons.
