Abstract

Kemampuan bernalar, khususnya berpikir kritis siswa Indonesia masih tergolong sangat rendah. Hal ini dapat dilihat dari hasil PISA 2018 yang menunjukkan bahwa Indonesia menduduki peringkat ke-7 dari bawah. Beranjak dari hal tersebut, peneliti akan mendeskripsikan proses berpikir kritis ditinjau dari kemampuan berpikir komputasi siswa. Adapun metode yang digunakan dalam penelitian ini adalah deskriptif dengan pendekatan kualitatif. Teknik pengumpulan data dilakukan dengan tes dan wawancara. Sedangkan penentuan subjek menggunakan teknik purposive sampling dengan mengambil 3 subjek usia 15 tahun jenjang SMP yang memilki kemampuan berpikir komputasi tinggi, sedang, dan rendah. Hasil penelitian menunjukkan bahwa dalam proses mengerjakan instrumen tes berupa soal PISA, berdasarkan aspek informasi subjek yang memilki kemampuan berpikir komputasi tinggi memenuhi indikator jelas, tepat, dan relevan. Selain itu subjek tersebut memenuhi indikator tepat dan relevan berdasarkan aspek konsep dan ide. Sedangkan pada aspek sudut pandang memenuhi indikator jelas dan luas, namun pada aspek penyimpulan subjek hanya memenuhi indikator logis.

Abstract

Analytical reasoning and computational thinking are two essential skills in mathematics education, especially in solving complex problems such as quadratic equations. This study aims to describe the analytical reasoning process of high school students in solving quadratic equation problems based on computational thinking skills. This study employs a descriptive qualitative approach, with data collected through tests and interviews with 30 students at a high school in Jember, categorized into three levels of computational thinking skill: high (S1), moderate (S2), and low (S3). One subject from each category was selected as a representative for in-depth analysis based on analytical reasoning indicators adapted from Fisher (2011), namely: problem identification, relationship analysis, strategy formulation, and solution evaluation and justification. The research results indicate that S1 demonstrates coherent and flexible analytic reasoning, characterized by precise problem identification, accurate model formation, adaptive strategy use, and implicit verification of results. S2 showed generally systematic reasoning, especially in translating contextual information into algebraic models and performing procedural operations. However, their analytic reasoning tended to rely on fixed procedures, with limited evaluative judgment or strategic adaptation. In contrast, S3 exhibited fragmented reasoning, difficulties in constructing symbolic models, and minimal solution validation, often caused by challenges in decomposing information and analyzing relational structures. These findings provide insights that can help teachers design more adaptive and effective learning strategies to encourage higher-order thinking skills in students.
