Abstract
This study aims to adapt the TPACK-21 (Valtonen et al., 2017) scale to Turkish. Based on the 21st century skills, this scale consists of 6-point Likert type items. Measuring the technological pedagogical content knowledge that teachers should have in order to integrate 21st century skills into their classroom settings will give an idea about whether they have the competencies recommended by the Ministry of National Education (2017). For the adaptation process, necessary steps were followed carefully by the researchers; permission, translation, pilot study, validity and reliability processes. The data were collected from 309 science and mathematics teachers in Turkey. For psychometric analysis of the scale, confirmatory factor analysis (CFA), item-total correlations for upper and lower groups according to 27% segment, and Cronbach's alpha reliability analysis were performed. According to the results, the adapted version of the scale was found as 6-factors and 37 items. Since the fit indices of CFA were found as acceptable values and Cronbach’s alpha coefficient was found as .97, the scale is valid and reliable. In addition, descriptive analysis was conducted according to demographic information.
