Özet:

This research aimed at developing an instrument to determine the anxiety levels of classroom teachers while teaching mathematics. The study group included 348 classroom teachers with experience levels of 1-10 years, 10-20 years and more than 20 yearsin Ankara, Gaziantep, and Şanlıurfa. The results revealed that the scale indicates a 3 factor- structure and a total of 23 items. The internal reliability of the instrument was found as .89. As a proof of the validity of the scale, medium and high level positive correlations were observed between the total scores obtained from the top and bottom of the scale and sub factors (r= .93, .57 and .76). Model's coherence indexes related to confirmatory factor analysis were as follows: X²/sd (389.72 / 224) = 1.74, RMSEA= 0.057, RMR= 0.062, GFI= 0.87, CFI= 0.95, NFI= 0.89, NNFI= 0.94 and AGFI= 0.84. Based on the results of the study, the 23-item Mathematics Teaching Anxiety Scale can be claimed as a valid and reliable scale.
