Professional self-efficacy scale for information and computer technology teachers: Validity and reliability study

This study aims at developing a valid and reliable scale to measure information and communication technology (ICT) teachers’ self-efficacy related to the Turkish national framework of ICT competencies. For statistical procedures, data were respectively analyzed with exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Furthermore, test-retest procedure was carried out to confirm the time invariance of the scale. EFA results revealed that the scale’s seven-factor structure accounts for 65.90 percent of total variance. CFA results produced an acceptable statistical support for model-data fit between the observed item scores and the seven-dimension scale structure (X²/df= 1.98, RMSEA=.073, CFI=.86). The standardized regression weights between the latent and observed variables ranged from.57 to.89 and Cronbach’s alpha coefficient of the scale subdimensions ranged from.80 to.88. Besides, the item-scale correlations varied between values of.53 and.79. As a result, the developed scale is a likert questionnaire and composed of 33 five-point items with seven sub-dimensions.
