ABSTRACT
The purpose of the present study is to develop reliable and validate an attitude scale for geography courses. The study sample was composed of 920 ninth, tenth, eleventh and twelfth grade students studying in high schools in the provincial area of Sivas. The study sample was selected using random group sampling method.In line with the purpose of the study, after reviewing the literature, an item pool for the piloting process was created, and expert opinion was sought for the appropriateness of each item in the pool.The experts were asked to rate the items using a three-point Likert scale by using the labels "Appropriate", "Partially Appropriate" and "Not Appropriate".The items in the pool were revised by using the feedback from the experts before the scale was piloted.After the piloting process, the draft scale was administered to the study group. Exploratory factor analysis (EFA) was carried out to identify how the scale was structured, and along with other validity analyses, confirmatory factor analysis (CFA) was conducted to test the construct validity of the scale.The data were analysed using SPSS 17.0 and Lisrel 8.51. To test the construct validity of the scale, exploratory and confirmatory factor analyses were carried out. Item-test correlations, test re-test correlation and the Cronbach alpha internal reliability coefficient were calculated. In addition, a t-test was carried out to see if the items discriminated between the upper and lower 27% of the groups.According to the results of confirmatory factor analysis carried out to test the validity of the two-factor scale with 15 items, the proportion X2 to degree of freedom was slightly over 3 (3,10). Since all fitness values were within acceptable boundaries, the two-factor structure of the Attitude Scale for Geography Courses was considered to be a valid model. The Cronbach alpha reliability of the sub-scales and the overall scale (0,907) and the correlation coefficients between the subscales indicated that the scale was reliable.
