The main purpose of this study is to determine the effect of geography education on the acquisition of citizenship awareness with an experimental approach. A total of 140 students aged 16-18, who were studying at high schools, were included in the study. Firstly, the pre-test was applied to the participants, then 20 hours of online lessons were given in a total of 4 weeks, and finally, the post-test was applied. The data of the study were evaluated using quantitative analysis methods. The most basic finding of the research was that geography education significantly increased the citizenship awareness levels of students. Citizenship awareness levels of the students increased by 21% and this increase was found to be significant (p<0.05). And, the significant increase in all gender and GPA groups showed that geography education was beneficial for all students with different gender and achievement characteristics.
