This study gives results of the first phase of the 12-18 year old Turkish students' norm study of The Motivated Strategies for Learning Questionnaire (MSLQ), which developed by Pintrich, Smith, Garcia & McKeachie (1993). The scale was administrated to 1114 students from 3 primary schools and 3 high schools in Ankara in Turkish language, science, mathematics and social science courses. After eliminating the questionnaires which have missing and extreme values, the analyses were done on 762 valid questionnaires for motivation subscale and 1100 valid questionnaires for learning strategies subscale. Results of the confirmatory factor analyses show that the first subscale, Motivation, has six factors, and the second subscale, Learning Strategies, has nine factors according to original scale's factor structures. Depending on the results of the confirmatory factor analysis; 6 items from motivation subscale and 5 items from learning strategies subscale were removed due to their low factor loadings. The corrected item total correlations ranged 0.58 to 0.15 for motivation subscale, and 0.68 to 0.19 for learning strategies subscale.
