Özet:

The purpose of this study is to adapt “Chemistry Motivational Questionnaire- II- CMQ-II”, developed by Glynn, Brickman, Armstrong and Taasoobshirazi (2011), into Turkish and investigate validity and reliability of the Turkish version of the scale. The original version of the scale was composed of 25 items gathered under five factors (intrinsic motivation, self-determination, self-efficacy, career motivation and grade motivation). Firstly permission from the developers of the scale was sought. Thereafter, the items of the scale were translated into Turkish by researcher. The translation validity of the scale was examined by referring to the views of Eng- lish and Turkish language experts. Once the final form of the scale had been derived, an English language expert translated the items of the scale from Turkish to English. The results obtained from this translation indicated that the Turkish scale closely approximated the original English scale. Turkish version of the scale was adminis- tered to total of 306 high school students from Anatolian Teacher High School and Anatolian Imam and Preacher High School and 266 university students from Educa- tion Faculties of Bartin and Ataturk Universities. The item-total correlations were calculated, and items which had negative or low correlation with the total scale score were excluded from the scale. The construct validity of the scale was examined by exploratory and confirmatory factor analysis. Varimax rotation technique was used due to the separation into irrelevant factors. Finally the scale was constructed from 20 items gathered under five factors to university students and 19 items gathered under five factors to high school students. The reliability coefficient (Cronbach- Alpha) for the whole scale was calculated as .894 for university students and as .840 for high school students.
