The differences in the characteristics of each student during the learning process mean that educators must use the right learning approach to activate the students' abilities, especially in Civics subjects which want to produce individuals as citizens who are able to think critically in their lives. This critical thinking ability can be stimulated and achieved when there is an understanding that in the process of learning activities students have different methods, therefore this differentiated learning is good to apply so that students use their critical thinking skills optimally when studying Civics. This research uses a qualitative approach with literature study methods originating from various sources such as books, national and international journals. The results of the research show that it is very necessary to use a differentiated learning approach to optimize the use of students' critical thinking skills when studying Civics, with an intense emphasis on the different ways of learning for each student which is carried out by focusing educators' attention on planning in the content, process, and product sections.
