Abstract
Mathematical critical thinking ability is an essential 21st-century skill that students need to solve problems logically, systematically, and reflectively, and it is influenced by self efficacy, which refers to an individual’s belief in their own abilities. This study aims to describe students’ mathematical critical thinking abilities based on high, medium, and low self efficacy levels in the topic of Three-Variable Linear Equation Systems (SPLTV). This research employed a qualitative descriptive approach and was conducted at SMA Negeri 1 Dukun, Gresik Regency. The research subjects were selected using purposive sampling based on self efficacy questionnaire results, consisting of three eleventh-grade students representing each self efficacy category. Data were collected through self efficacy questionnaires, mathematical critical thinking tests, and semi-structured interviews. Data analysis was carried out using the Miles and Huberman model, including data reduction, data display, and conclusion drawing. The results show that students with high self efficacy demonstrate strong mathematical critical thinking abilities across all Facione indicators, students with moderate self efficacy show fairly good abilities with some limitations, while students with low self efficacy experience difficulties in identifying problems and drawing appropriate conclusions. These findings indicate that self efficacy influences variations in students’ mathematical critical thinking abilities.
Keywords: Self efficacy, Mathematical critical thinking, SPLTV, Qualitative research.
Abstrak
Kemampuan berpikir kritis matematis merupakan keterampilan penting abad ke-21 yang diperlukan peserta didik untuk menyelesaikan masalah secara logis, sistematis, dan reflektif, serta dipengaruhi oleh self efficacy sebagai keyakinan terhadap kemampuan diri. Penelitian ini bertujuan untuk mendeskripsikan kemampuan berpikir kritis matematis peserta didik berdasarkan kategori self efficacy tinggi, sedang, dan rendah pada materi Sistem Persamaan Linear Tiga Variabel (SPLTV). Penelitian ini menggunakan pendekatan deskriptif kualitatif dan dilaksanakan di SMA Negeri 1 Dukun, Kabupaten Gresik. Subjek penelitian dipilih melalui teknik purposive sampling berdasarkan hasil angket self efficacy, yaitu tiga peserta didik kelas XI yang mewakili masing-masing kategori. Pengumpulan data dilakukan melalui angket self efficacy, tes kemampuan berpikir kritis matematis, dan wawancara semi-terstruktur. Data dianalisis menggunakan model Miles dan Huberman. Hasil penelitian menunjukkan bahwa peserta didik dengan self efficacy tinggi memiliki kemampuan berpikir kritis matematis yang baik pada seluruh indikator Facione, peserta didik dengan self efficacy sedang menunjukkan kemampuan cukup baik, sedangkan peserta didik dengan self efficacy rendah mengalami kesulitan dalam mengidentifikasi masalah dan menarik kesimpulan, sehingga self efficacy memengaruhi variasi kemampuan berpikir kritis matematis peserta didik.
Kata kunci: Self efficacy, Berpikir kritis matematis, SPLTV, Penelitian kualitatif.
