TURKISH ADAPTATION OF THE SURVEY OF PEDAGOGICAL CONTENT KNOWLEDGE IN EARLY CHILDHOOD MATHEMATICS EDUCATION
The aim of this study is to adapt the Survey of Pedagogical Content Knowledge in Early Childhood Mathematics, developed by Smith (1998), to Turkish. The need for a scale investigating the pedagogical content knowledge of teachers in the field of early childhood education ensures the relevance of the current study. After the translation stage of the Turkish form, it was applied to 80 preschool teachers and 110 preschool teacher candidates; a total of 190 people. Statistical analysis of the data obtained in the study was completed with SPSS 10.0, LISREL 8.8 and Excel programs. To determine the fit of the applied scale to the original structure and to test the validity of the structure, confirmatory factor analysis was used. To determine the validity of the scale in terms of internal consistency, the Kuder Richardson-20 Reliability Coefficient was calculated. The KR-20 reliability coefficient for the applied scale was found to be 0.71. The results indicated that the Turkish adaptation of the scale was comprised of sub-factors like the original scale, the data obtained from teachers in the research fit with the six-factors model, the internal consistency coefficients of the factors of the scale were sufficient and the scale served its purpose.
