The methodology used in this research was a descriptive quantitative method. The participants of the study were twenty-seven German and thirty-three Turkish mathematics teachers. Data analysis involved both descriptive and inferential statistics. Effect sizes were also calculated. The findings revealed that: (1) the interaction effect between nationality and gender group was not statistically significant; (2) the main effect for gender did not reach statistical significance; and (3) there was a statistically significant main effect for nationality.
