Abstract

AbstrakSiswa mengalami kesulitan dalam memecahkan masalah Trigonometri yang berdampak pada rendahnya hasil belajar. Artikel ini bertujuan untuk menganalisis kesalahan siswa memecahkan masalah trigonometri ditinjau dari strategi pemecahan masalah Polya. Penelitian ini merupakan penelitian eksploratif menggunakan pendekatan kualitatif deskriptif. Penelitian dilaksanakan dengan melibatkan 1 guru dan 20 siswa SMA. Data penelitian ini dikumpulkan melalui tes dan wawancara. Tes terdiri atas 5 masalah Trigonometri. Wawancara semi terstruktur diberikan pada; (1) guru untuk mengetahui kesulitan yang dialami siswa selama proses pembelajaran Trigonometri, dan (2) siswa untuk mengidentifikasi kesalahan dalam memecahkan masalah. Data dianalisis dengan tahapan berikut; (1) jawaban siswa diperiksa lalu di hitung skor untuk setiap masalah, (2) di identifikasi jenis kesalahan siswa pada setiap masalah, (3) persentase banyaknya siswa dihitung pada tiap jenis kesalahan, dan (4) siswa yang melakukan kesalahan diwawancara untuk mengetahui penyebab dan jenis kesalahan. Penelitian ini menemukan bahwa kesalahan siswa dalam memecahkan masalah Trigonometri adalah: (i) Kesalahan memahami masalah Trigonometri (57,73%); (ii) Kesalahan dalam merencanakan strategi (9,27%); (iii) Kesalahan menerapkan solusi (15,83%); dan (iv) kesalahan dalam memeriksa kembali (17,16%).  Student Errors in Solving Trigonometry Problems in View from Polya’ Problem Solving IndicatorsAbstractStudents have difficulty in solving trigonometric problems which have an impact on low learning outcomes. This article aims to analyze students' errors in solving trigonometric problems in terms of Polya's problem-solving strategy. This research is exploratory research using a descriptive qualitative approach. The research was conducted by involving 1 teacher and 20 high school students. The data of this study were collected through tests and interviews. The test consists of 5 Trigonometry problems. Semi-structured interviews were given on; (1) teachers to find out the difficulties experienced by students during the Trigonometry learning process, and (2) students to identify errors in solving problems. The data were analyzed in the following steps; (1) student answers are checked and then the score is calculated for each problem, (2) the types of student errors are identified in each problem, (3) the percentage of the number of students is calculated for each type of error, and (4) students who make mistakes are interviewed to find out the cause and the type of error. This study found that students' errors in solving Trigonometric problems were: (i) Misunderstanding of Trigonometric problems (57.73%); (ii) Errors in devising a plan (9.27%); (iii) Error in performing the plan (15.83%); and (iv) errors in looking back/ confirmation of the answer (17.16%).

Abstract

The top three levels in Bloom's taxonomy of learning objectives, which includes analysis, synthesis, and evaluation, are critical thinking skills. Critical thinking abilities among students range widely. Based on aspects of critical thinking and universal intellectual standards, this research seeks to investigate the level of critical thinking competencies of tadris mathematics students in the topic of node coloring graph material. Descriptive analysis is the method of research used in this qualitative research technique. 14 fourth-semester students served as the research subjects for this study, which was carried out at the Mathematics Tadris Study Program at Institut Agama Islam Negeri (IAIN) Takengon. The tools employed include validation sheets, interview sheets, and critical thinking skills. Tests and interviews are used to acquire data. There are five stages in the critical thinking level (TBK). According to the study's findings, no pupils met the criteria for critical (TBK 3) and very critical performance (TBK 4). The subject level of students' critical thinking is based on critical thinking components, with 3 students (TBK 2) being quite critical, 10 students (TBK 1) being less critical, and 1 student (TBK 1) not being critical (TBK 0). This research demonstrates that students' critical thinking skills are still very low, hence enhancements to teaching strategies and learning activities are required.
