Özet:

The aim of this research is examine the psychometric properties of the Scale of Beliefs About the Effectiveness of Teacher Education Program developed for the international TEDS-M Study (Tatto et al., 2008). The research was conducted on 583 preservice elementary mathematics teachers from different universities selected randomly from seven different geographical regions of Turkey. As a result of the exploratory factor analysis, it was found that total explained variance was 65% and that the items were grouped under a single factor. Results of confirmatory factor analysis demonstrated that the scale yielded single factor as the original form and that the model was well fit (x2=25.83, df=9, RMSEA=0.08, GFI=0.96, AGFI=0.89, CFI=0.98, NFI=0.97, NNFI=0.95). Corrected item-total correlations ranged 0.78 to 0.84. Internal consistency coefficient was found as 0.90 for the scale. These results show that the Turkish form of the scale is a valid and reliable instrument.
