Abstract

Abstract: This study aims to describe the reflective students' critical thinking process in solving the problem of two-variable linear equation system. Instruments used to know the critical thinking process of the subject is a problem-solving test and interview. Through tests and interviews, we can analyze the critical thinking process of the subject based on six criteria focus, reason, inference, situation, clarity, and overview. The results showed that both subjects only met the criteria of focus, and experienced errors in making mathematical models, so that both are not able to solve the problem.Abstrak: Penelitian ini bertujuan untuk mendeskripsikan proses berpikir kritis siswa reflektif dalam menyelesaikan masalah sistem persamaan linier dua variabel. Instrumen yang digunakan untuk mengetahui proses berpikir kritis subjek adalah tes pemecahan masalah dan wawancara.

Abstract

Abstract: This study used a qualitative-descriptive study with the aim of this study to describe the pointing profile and gesture representation of students in solving mathematical problems with the material of linear functions. The subjects in the study were 2 students of class X SMA Negeri 2 Dompu. The research subjects were selected by 1 student as the pointing gesture and 1 student as the representational gesture. Data was collected by providing assignments, gesture observation sheets, and interviews with selected subjects. The data were analyzed qualitatively through data reduction, data presentation, and drawing conclusions. This study resulted that the pointing gesture helped P1 describe the answer completion plan, helped focus himself to perform calculations, generate ideas, and facilitate the description of information from questions and answers as well as check and understand questions and answers when solving questions. Representational gesture helps R1 to describe the steps to understand the graphic related to the problem, helps focus on understanding the problem and can be careful in solving the problem. Also plays a role in concretizing ideas/ideas that are being worked on or are being thought of by students.Abstrak: Penelitian ini menggunakan penelitian kualitatif-deskriptif dengan tujuan penelitian ini untuk mendeskripsikan profil pointing dan representasi gesture siswa dalam menyelesaikan soal matematika materi fungsi linear. subjek dalam penelitian adalah 2 orang siswa kelas X SMA Negeri 2 Dompu. Subjek penelitian dipilih 1 orang siswa sebagai pointing gesture dan 1 orang siswa sebagai representational gesture. Perolehan data dilakukan dengan memberikan lembar tugas, lembar Observasi gesture, dan wawancara yang terpilih menjadi subjek. Data di analisis secara kualitatif melalui reduksi data, penyajian data, dan menarik kesimpulan. Penelitian ini menghasilkan bahwa Pointing gesture membantu P1 menggambarkan rencana penyelesaian jawaban, membantu memfokuskan dirinya untuk melakukan hitungan, memunculkan ide, dan mempermudah gambaran informasi dari soal dan jawaban serta mengecek dan memahami soal dan jawaban saat menyelesaikan soal. Representational gesture membantu R1 untuk menggambarkan langkah memahami grafik terkait hubungan dengan soal, membantu memusatkan perhatian memahami soal dan dapat teliti dalam menyelesaikan soal. Berperan juga untuk mengkongkretkan ide/gagasan yang sedang dikerjakan maupun sedang dipikirkan siswa.

Abstract

This study aims to describe the internal cognitive conflicts that occur to students when they were solving mathematics problems. There were two participants in this research. They were 7th grade students from SMPN 1 Malang. The first participant was a student who has experienced internal cognitive conflicts and has capability to resolve it as well as the mathematics problems. Meanwhile, the second participant was a student who has experienced internal cognitive conflict but cannot resolve that conflict and also the mathematics problems. This research was used descriptive qualitative. The data of this study was gathered from students’ test on cognitive conflict and interview which was adapted from Newman's interview procedure. It was found that, the students who are able to find a relationship between the ratio of the number of workers and the number of chairs produced in a day, have capability to resolve their cognitive conflicts so that it brings them to the right problem solving. Meanwhile, the students that fail to build a relationship between the comparison concepts with mathematics problems and fail to find the relation between the numbers of people with the number of chairs in one day can not resolve the cognitive conflict so that they solve the problems in the wrong ways.

Abstract

This study aimed at investigating the relationship between student’s algebraic thinking and cognitive style of Field Independent (FI) and Field Dependent (FD). The method implemented in the study is Group Embedded Figure Test (GEFT) which was intended to categorize students into the FI and FD styles. Afterward, to collect the data of students’ algebra thinking ability, a test was administered. The result of the test was compared to the result of GEFT test by integrating a computer program to find out the relationship between the students’ algebraic thinking and their cognitive styles, both FD and FI. The subjects of this research were the eighth-grade students totaling at 24 students. The findings of this study indicate that there is no relationship between manipulating symbols and students’ cognitive style.. There is a relationship between generalizing and formalizing and stundents’ cognitive styles. There is a relationship between using algebra as a tool and FD. There is a relationship between reasoning and representation and student’s cognitive style.

Abstract

Penelitian ini bertujuan untuk mendeskripsikan kemampuan berpikir kritis siswa pada materi bangun datar ditinjau dari gaya belajar. Jenis penelitian ini adalah deskriptif kualitatif. Subjek penelitian adalah siswa kelas VIII SMPN 1 Jereweh, Kabupaten Sumbawa Barat. Subjek penelitian sebanyak 8 dengan masing-masing dua siswa dari visual, auditori, kinestetik dan visual-auditori. Data penelitian diambil dari kuesioner gaya belajar, lembar tes siswa, dan wawancara. Teknik analisis data pada penelitian ini yaitu reduksi data, penyajian data, dan penarikan kesimpulan. Data kuesioner dilakukan untuk menentukan kecendrungan gaya belajar siswa, sedangkan lembar tes untuk mengetahui kemampuan berpikir krtitis siswa. Hasil penelitian menunjukkan bahwa kemampuan berpikir kritis siswa pada masing-masing gaya belajar memiliki tingkatan yang berbeda. Siswa dengan gaya belajar visual memiliki kemampuan berpikir kritis pada kategori cukup kritis, siswa dengan gaya belajar auditorial memiliki kemampuan berpikir kritis pada kategori kurang kritis, siswa dengan gaya belajar kinestetik memiliki kemampuan berpikir kritis pada kategori cukup kritis, sedangkan siswa dengan gaya belajar visual-auditori memiliki kemampuan berpikir kritis pada kategori kritis. Dari 3 gaya belajar tersebut didapatkan bahwa gaya belajar visual memiliki kemampuan berpikir kritis lebih baik dari auditori dan kinestetik. This study aims to describe students' critical thinking ability on two-dimentional figure material in terms of learning styles. This type of research is descriptive qualitative. The research subjects were students of class VIII SMPN 1 Jereweh, West Sumbawa Regency. The research subjects were 8 with two students each from visual, auditory, kinesthetic and visual-auditory. The research data were taken from learning style questionnaires, student test sheets, and interviews. Data analysis techniques in this study are data reduction, data presentation, and drawing conclusions. Questionnaire data was conducted to determine the tendency of students' learning styles, while the test sheet was to determine students' critical thinking ability. The results showed that students' critical thinking ability in each learning style had different levels. Students with visual learning styles have critical thinking ability in the moderately critical category, students with auditory learning styles have critical thinking ability in the less critical category, students with kinesthetic learning styles have critical thinking ability in the moderately critical category, while students with visual-auditory learning styles have the ability to think critically in the critical category. From the 3 learning styles, it was found that the visual learning style has better critical thinking ability than auditory and kinesthetic.
