Berpikir kritis siswa ditinjau dari gaya kognitif visualizer dan verbalizer dalam menyelesaikan masalah geometri

Student's strategy in solving mathematics problem cannot be separated from the way students receive and process the information which is called as cognitive style. Students have different cognitive styles as they learn. They tend to have visualizer cognitive style and the others have verbalizer. The different cognitive styles will trigger students' critical thinking skills. This research was conducted in Madrasah Tsanawiyah Daru'l Hikam Cirebon using the quantitative method of a causal-comparative. The sampling technique used cluster random sampling, with a total sample of 45 students, 24 students are visualizer and the remaining is verbalizer. The results showed that the visualizer students obtained an average score of 50.15, while the verbalizer students got 40.05. Viewing from the average percentage of the results of each aspect of critical thinking, visualizer students can be categorized quite well, while the verbalizer students can be categorized less. This research implies that there are differences in critical thinking between students with visualizer cognitive style and students with verbalizer in solving geometry problems.
