Özet:

This study involves the adaptation of a scale into Turkish which is developed by Thomas, Anderson and Nashon (2008) to investigate elements of students’ metacognition, self-efficacy and constructivist science learning processes. In this context linguistic equivalence, validity and reliability analyses were conducted. The scale was administered to 913 secondary school students aged between 15 and 18 years of age in four cities of Turkey. Results of the confirmatory factor analyses [(395, n=913)=1137.10, p<.000; RMSEA=.045; GFI=.92; CFI=.93; NNFI=.92] show that five factorial construct of the original scale was preserved in the Turkish form. Factor loadings differ from 0.50 to 0.70 for items and item-total score correlations ranged from 0.39 to 0.65. The Cronbach alpha coefficient for whole scale was also calculated as 0.93.
