Analisis Kemampuan Berpikir Kritis Siswa SMA Dalam Menyelesaikan Masalah Logaritma Berdasarkan Gaya Kognitif Visualizer-Verbalizer

Abstract

The implementation of the 2013 revised curriculum requires students to be able to think critically. The field of mathematics, especially logarithmic material, contains many characteristics, so it requires the ability to think critically to solve the problem. Meanwhile, the ability to think critically is influenced by students' cognitive styles, such as the visualizer and verbalizer cognitive styles. So it is necessary to do research to analyze students' critical thinking skills in solving logarithmic problems viewed from the two cognitive styles. This qualitative descriptive research is used by the teacher as a learning design or strategy so that it can improve students' critical thinking skills according to their cognitive style. The subjects are class X students of SMAN 1 Kamal with visualizer and verbalizer cognitive style. The data analysis technique begins with the VVQ cognitive style test (Visualizer-Verbalizer Questionnaire), problem-solving tests, and interview tests. The results obtained by the visualizer subject in TPM 1 were 14 (good critical thinking category), and TPM 2 scored 12 (adequate critical thinking category). While the verbalizer subject in TPM 1 has a score of 13 (adequate critical thinking category), and TPM 2 is 9 (adequate critical thinking category). Based on the research results, it can be concluded that the critical thinking ability of the visualizer subject dominates compared to the verbalizer subject, because it is able to detect inconsistencies and solve problems systematically.
