Examining Validity and Reliability of Transformational Teaching Questionnaire

Purpose of this research was to adapt Beauchamp and colleagues’ (2010) "Transformational Teaching Questionnaire" to Turkish that is inspired by the transformational leadership concept from theories of leadership. 265 high school students between 15-19 (Mage = 16, SD = .95) years old (141 girls and 124 boys) participated to this study. The questionnaire is used for evaluation of students’ perceptions about their teacher. A questionnaire composed of 16 items and four subscales as; idealized influence, inspirational motivation, intellectual stimulation, and individualized consideration. Pearson correlation analysis, Cronbach’s alpha coefficient, and confirmatory factor analysis were used for data analyses. For a model with 16 items and 4 factors, the correlations between Turkish and original (English) forms were found between 0.79-0.94 while, test-retest correlations were between 0.77-0.85. Internal consistency values varied between 0.78-0.87. Moreover, factor loadings were calculated between 0.48 and 0.83. According to the confirmatory factor analysis results, model fit indices (χ2/sd= 2.474, RMSEA= 0.075; CFI=0.98, NFI=0.97, NNFI=0.98, IFI=0.98, RFI=0.97, GFI=0.90, AGFI=0.86) indicated the data compatibility of the model appeared to be within acceptable and perfect limits. It can be said that the Turkish version of the “Transformational Teaching Questionnaire” can be used as a valid and reliable measurement tool in researches
