Abstract

Abstrak: Kemampuan berpikir kritis matematis siswa Indonesia masih tergolong rendah, salah satunya disebabkan oleh penerapan metode pembelajaran yang kurang melibatkan partisipasi aktif dan belum mendukung perkembangan self-concept siswa secara optimal. Self-concept (konsep diri) dapat mempengaruhi kemampuan berpikir kritis matematis pada pembelajaran matematika. Penelitian ini bertujuan untuk mengetahui pengaruh metode Fish Bowl Discussion berbasis Learning Cards terhadap kemampuan berpikir kritis matematis, self-concept, serta pengaruh keduanya secara simultan pada siswa SMP kelas VIII di Kabupaten Lampung Utara. Penelitian ini menggunakan jenis penelitian Quasy Experimental Design. Populasi pada penelitian ini adalah siswa SMP kelas VIII dengan sampel yang diambil menggunakan teknik Stratified Random Sampling berjumlah 59 siswa. Instrumen yang digunakan untuk mengumpulkan data yaitu instrumen tes esai kemampuan berpikir kritis matematis dan angket self-concept. Teknik analisis data pada penelitian ini menggunakan Multivariate Analysis of Variance (MANOVA) dengan nilai signifikan sebesar α=5%. Berdasarkan perhitungan yang telah dilakukan, mendapatkan hasil bahwa p-value dari kemampuan berpikir kritis matematis dan self-concept (konsep diri) sebesar 0,000, sehingga p-value dari masing-masing kemampuan kurang dari 0,05, maka dapat disimpulkan terdapat pengaruh metode fish bowl discussion berbasis learning cards terhadap kemampuan berpikir kritis dan self-concept siswa secara parsial maupun simultan. Abstract: Students' mathematical critical thinking skills in Indonesia remain relatively low, partly due to the use of learning methods that do not sufficiently involve active student participation and have not optimally supported the development of students' self-concept. Selfconcept can influence students' mathematical critical thinking skills in mathematics learning. This study aims to determine the effect of the Fish Bowl Discussion method based on Learning Cards on mathematical critical thinking skills, self-concept, and their simultaneous effect on eighth-grade junior high school students in North Lampung Regency. This study employed a Quasi-Experimental Design. The population of this research consisted of eighth-grade junior high school students, with a sample of 59 students selected using the Stratified Random Sampling technique. The instruments used to collect the data were an essay test to measure mathematical critical thinking skills and a self-concept questionnaire. The data analysis technique used in this study was Multivariate Analysis of Variance (MANOVA) with a significance level of α = 5%. Based on the calculations, the p-value for mathematical critical thinking skills and self-concept was 0.000. Since the p-value for each variable was less than 0.05, it can be concluded that the Fish Bowl Discussion method based on Learning Cards has a significant effect on students' mathematical critical thinking skills and self-concept, both partially and simultaneously.
