Özet:

This study aimed at developing an instrument to determine the mathematics anxiety of teachers. The study group constitutes 487 teachers from different disciplines. First, a literature review was conducted to develop Math Anxiety Scale for Teachers (MAS-T). Also, semi-structured interviews were conducted with teachers of different subjects. An instrument consisting of 5 factors and 33 items were obtained after performing a factor analysis. Model's coherence indexes related to confirmatory factor analysis were as follows: X²/sd = 2.71, RMSEA= 0.07, SRMR= 0.07, GFI=  0.91, CFI=  0.92, NNFI= 0.93 ve AGFI=  0.90. Total internal consistency coefficient Cronbach Alpha (α) was obtained as .91. The findings of the criterion validity (.81) showed that the scale served itspurpose. After the analyses, Math Anxiety Scale for Teachers (MAS-T) was found to be a valid and reliable scale.
