    (Artvin Çoruh Üniversitesi, 2021) Kaplan, Ebru; Bektaş, Oktay; Karaca, Melek
    The aim of this study is to develop a motivation scale that can be used to determine the motivation levels of secondary school students for a science course. This study was conducted in accordance with quantitative research survey, and accessible populations of the study consisted of fourth district secondary school students in Melikgazi district of Kayseri province, and 386 secondary school students in the sample. Based on “Social Cognitive Theory” in this study, the scale was developed to determine students ' motivation levels for the science. It was ensured that there were sufficient substances of all sizes on the scale and the necessary corrections were made by checking two science education experts throughout the process. Validity and reliability of the draft scale applied to the sample group were analyzed. Within the scope of construct validity, EFA and CFA were performed. As a result of EFA, the KMO value of the scale was calculated as 0.95, and it was found that the scale elements explain 59% of the total variance. The reliability analysis was repeated over the remaining 21 questions after the substances removed during the factor analysis and calculated as 0.93. As a result, a valiable and reliable measurement tool has been developed that can be used by both researchers and teachers to determine the motivation levels of secondary school students for a science lesson.
