Adaptation and empirical evaluation of the questionnaire on students' motivation towards science learning

The aim of this study is to verify the psychometric properties of the translation of the questionnaire which is designed for self-assessment of students' motivation toward science learning, SMTSL. Besides being translated and adapted to Serbian language, the questionnaire was adapted to the specific properties of chemistry as a school subject. The administered questionnaire consisted of 29 items in the five-point Likert scale and contained five subscales which assessed a sense of self-efficacy for learning chemistry, active learning strategies, chemistry learning value, performance goal and achievement goal. The suitability of the theoretical model and psychometric characteristics of the questionnaire were assessed on the sample of 741 grammar school students. The results show that the tested model has good fit indicators. The calculated values of the indicators of reliability and representativeness indicate quite satisfactory psychometric properties of the questionnaire and it can be used in further research.
