Development of The Scale for Identifying Perceptions of Having 21st Century Skills of Pre-service Teachers: Validity and Reliability Study

Present study aims at developing a scale to identify pre-service teachers' perceptions of having 21st century skills. It was carried out with two different participant groups using survey method through maximum variation sampling method. The study was conducted with a total of 827 participants (439 for exploratory factor analysis (EFA) and 388 for confirmatory factor analysis (CFA). SPSS program was used to analyze data for EFA and SPSS AMOS program was used for CFA. The 'Scale for Identifying Perceptions of Having 21st Century Skills' was developed based on the EFA results, revealing a 44.188% total variance. The scale consisted of 19 items with a 3-factor structure. The CFA indicated good fit indices for the scale, and an internal consistency coefficient of .858 Cronbach's Alpha was obtained. The findings of this study indicate that the developed scale meets the theoretical and statistical criteria outlined in the relevant literature for pre-service teachers. Therefore, the instrument has potential as a reliable and valid measure of pre -service teachers' perceptions for possessing 21st century skills.
