This study aims to explain the impact of learning model and gender on critical thinking skills of junior high school students in a rural school environment. The population used is the students of the State High School IX first semester who have acquired material on the Circles and Circle Line in Pringsewu Lampung District. Think Talk Write (TTW) is a learning model that is used with the type of descriptive research and experimental semu. Data analysis using two-way ANOVA assisted SPSS 25 with a significant scale of 0.05. After the treatment, the difference in critical thinking ability based on gender obtained a significance of 0,072 > 0,05. The significance value of the learning model factor is 0,013 < 0,05, while the significance rate of the interaction of the learning model with gender is 0,230 > 0,05, so it does not give a difference to the ability to think critically. Therefore, this study indicates that only model factor influences the ability to think critically about geometry.
