Adapting the teacher formative assessment literacy scale into Turkish: Validation and reliability study

In the present study, the Teacher Formative Assessment Literacy Scale (TFALS), developed by Yan and Pastore (2022a), was translated into Turkish to examine the factor structure and psychometric characteristics of the scale in a Turkish sample. Data was collected from 318 teachers, of whom 168 were males and 150 were females, working in different state schools in a city in the Central Anatolia Region of Türkiye. As the first step, the scale items were translated and back-translated by experts in both English and Turkish. Afterward, experts were presented with the scale to check for consistency and accuracy based on the feedback received. A pilot study was carried out to establish the linguistic equivalence of the scale, followed by an examination of its structural validity in a Turkish sample. To demonstrate evidence of the confirmed factor structure of TFALS with 22 items, the confirmatory factor analysis (CFA) was conducted. The CFA results demonstrated that the three-factor model of the TFALS-Turkish-version had adequate fit indices. The Cronbach’s alpha coefficient of the total scale was found to be .93. The Cronbach’s alpha for each of the dimensions of TFALS was .90 for the conceptual dimension (7 items), .86 for the practical dimension (8 items), and .88 for the socio-emotional dimension (7 items). Composite reliability coefficients of the dimensions ranged from .78 to .84. The results of this study provide important evidence for the validity and reliability of the Turkish version of the TFALS, confirming that it has good psychometric properties in a Turkish sample
