Analisis Kemampuan Berpikir Kritis Matematis Ditinjau dari Aspek Overview

Abstract

: This study aims to determine students' mathematical critical thinking skills in terms of overview aspect. This research type is a quantitative descriptive study, with a population of all students of class XII from senior high schools in Pacitan Regency and the sample is 141 students which are determined by purposive sampling technique. Research data was taken through tests of critical thinking skills, questionnaires and interviews. The test result data were analyzed based on aspects of mathematical critical thinking ability (FRISCO). The results showed that students' mathematical critical thinking skills in the overview aspect were still low. These can be described as follows: (1) based on the analysis of test results, the overview aspect is included in the achievement of the lowest aspects of 72,6; (2) the results of the questionnaire analysis showed that the average percentage in the overview aspect was 58,16% including in the medium category; (3) the interview results showed that most students only examined and checked the final result of their works. 141 siswa yang ditentukan dengan teknik purposive sampling. Data penelitian diambil melalui tes kemampuan berpikir kritis, angket dan wawancara. Data hasil tes dianalisis berdasarkan aspek kemampuan berpikir kritis matematis (FRISCO). Hasil penelitian menunjukkan bahwa kemampuan berpikir kritis matematis siswa pada aspek overview masih tergolong rendah. Hal tersebut dapat dijabarkan sebagai berikut: (1) berdasarkan analisis hasil tes, aspek overview termasuk pada pencapaian aspek yang paling rendah sebesar 72,6; (2) hasil analisis angket menunjukkan persentase rata-rata pada aspek overview sebesar 58,16% termasuk pada kategori sedang; (3) hasil wawancara menunjukkan sebagian besar siswa hanya memeriksa dan mengecek pekerjaan pada hasil akhir saja.
