Development of Chemistry Lesson Motivation Scale for Secondary School Students

The aim of this study is to develop a valid, reliable and up-to-date measurement tool that determines the motivations of secondary school students towards Chemistry Research Interest, Performance, Collaborative Work and Communication, and Chemistry Learning, taking into account the secondary school chemistry curriculum. 336 students from different schools participated in the study. As a result of the study, a reliable and valid measuring instrument consisting of three sub-factors measuring the motivation of the secondary school students towards the chemistry course was developed. The Cronbach's alpha reliability coefficient of your scale is 0.962. The reliability coefficients of the subscales of the scale ranged from 0.951 to 0.871, and the factor loadings of the scale items ranged from 0.852 to 0.492. The total variance explained by the scales was found to be 63,857%. Confirmatory factor analysis of the three-factor structure of the scale revealed a resultant RMSEA value of 0.09. The results show that your scale is a reliable and valid tool. (Powered by Google Translate)
