Beliefs of Preservice Elementary Mathematics Teachers About The Effectiveness of Teacher Education Program: Scale Validi-ty And Reliability Study

Serhat AYDIN, Derya ÇELİK

Abstract


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.
