ATTITUDE SCALE TOWARDS T.R. REVOLUTION HISTORY AND ATATURKISM COURSE: VALIDITY AND RELIABILITY STUDY
Abstract
The purpose of the present study is to develop reliable and validate an attitude scale towards attitude scale towards T. C. Revolution History and Ataturkism Course. The study sample was composed of 671 eighth grade students studying in secondary 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. 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 PASW 18.0 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 three-factor scale with 23 items, the proportion X2 to degree of freedom was ≤ 5( 4,89). Since all fitness values were within acceptable boundaries, the three-factor structure of the Attitude Scale was considered to be a valid model. The Cronbach alpha reliability of the sub-scales and the overall scale (0,80) and the correlation coefficients between the subscales indicated that the scale was reliable.
