Abstract:

This study investigated the relationships between the motivation, gender, grade level and academic achievement using adapted Intrinsic and Extrinsic Motivation Scale (IEMS). The survey method was used in the research. The sample consists of 994 secondary school students in Istanbul during the 2013-2014 academic year. Data was analyzed through confirmatory factor analysis and MANOVA. The findings indicated that the IEMS was a valid and reliable scale for determining the motivation orientations of secondary school students. It was found that the extrinsic motivation scores differ significantly with respect to grade level, while the intrinsic motivation scores showed significant differences according to gender, grade level and academic achievement. An analysis of the gender and grade level variables revealed significant differences in the intrinsic motivation scores. The findings of the study are discussed based on the literature
