Abstract
The aim of this study is to develop a valid and reliable astronomy attitude scale for secondary school students. The method of this research is a scale development study. The study group of the research consists of 300 students studying in 3 different secondary schools in Turkey in the first semester of the 2022-2023 academic year. A 32-item 5-point Likert-type scale was prepared with the data collected from the experts. In the first stage, exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were conducted within the scope of validity analysis for the scale whose reliability value was calculated at a "very good" level. In the EFA stage, a total of 12 items with high loading values in more than one factor were removed from the scale due to overlapping, and the explained variance of the 3-factor 20-item scale was found to be 53.704%. In the confirmatory factor analysis stage, the model fit of the 20 items with three factors determined in the EFA stage was tested with the SPSS AMOS programme. At this stage, one more item with low standardized loadings was removed from the scale and model fit values were calculated as χ2 /sd=1,907; GFI=,913; CFI=,941; NFI=,885; RMSEA=,055 and it was determined that the model showed "acceptable" and "excellent" fit. Cronbach's Alpha values were calculated as 0.914 for the whole scale. As a result of the construct validity and reliability analyses of the scale, the values found in the analyses showed that the astronomy attitude scale is a valid and reliable scale for secondary school students.
