Abstract

Kemampuan penalaran matematis diperlukan dalam memahami matematika dan dalam menyelesaikan masalah sehari-hari, mahasiswa memerlukan. Kemampuan Indonesia di dunia pendidikan dalam bidang matematika masih sangat rendah. Berdasarkan hal tersebut, penelitian ini bertujuan untuk mengetahui penalaran matematis mahasiswa dengan kemampuan berpikir intuitif sedang dalam memecahkan masalah analisis real. Penelitian ini menggunakan pendekatan kualitatif dengan jenis penelitian deskriptif kualitatif. Sumber data yang digunakan pada penelitian ini adalah mahasiswa. Teknik pengumpulan data melalui tes tulis dan wawancara. Analisis data dalam penelitian ini dilakukan dengan tahapan reduksi data, penyajian data, dan penarikan simpulan. Berdasarkan hasil penelitian diperoleh kesimpulan bahwa mahasiswa dengan kemampuan berpikir intuitif sedang pada pemecahan masalah analisis real memiliki kecenderungan melaksanakan penalaran matematis dengan kurang sempurna. Mahasiswa dengan kemampuan berpikir intuitif sedang tidak mampu melaksanakan penalaran matematis pada tahap pemecahan masalah menyelesaikan masalah sesuai rencana dan melakukan pengecekan kembali. Mathematical reasoning capability is needed in the understanding of mathematics and in the problem solving of daily activity, student need. Indonesian education capability in mathematics is low. Based on that fact, the aim of this research is for knowing student mathematical reasoning with medium intuitive thinking capability in the problem solving of real analysis. This research uses qualitative method with the kind of method is qualitative descriptive. Data resource that is used in this research is student. Data collecting technique is done by using writing test and interview. Data analysis in this research is done by data reduction, data display, and data verification. Based on research result is gotten conclusion that student with medium intuitive thinking capability in the problem solving of real analysis can do mathematical reasoning less completely. Student with medium intuitive thinking capability cannot do mathematical reasoning in every step solving problem based on plan and doing answer checking .

Abstract

 Abstract: Mathematical reasoning ability is needed by students both in the process of understanding mathematics and in everyday life context. In fact, Indonesian students’ ability in the field of mathematics is still very low. Referring to the fact, this study is attempted to determine students' mathematical reasoning in solving real analysis problems based on their ability to think intuitively. This study is a qualitative descriptive research. The data sources in this study are college students. Data are collected through written tests and interview. Data analysis in this study is carried out by stages of data reduction, data presentation, and conclusion. The results show that (1) Students with high intuitive thinking skills in real analysis problem solving have a tendency to implement mathematical reasoning perfectly. They are able to carry out mathematical reasoning at each stage of solving real analysis problems. (2) Students with medium intuitive thinking ability in solving real analysis problem have a tendency to implement mathematical reasoning less perfectly. They are not able to carry out mathematical reasoning at the stage of solving problems according to plan and re-checking it again. (3) Students with low intuitive thinking skill in solving real analysis problem have a tendency to implement mathematical reasoning imperfectly. They are unable to carry out mathematical reasoning at the stage of planning solution and solving problem.Keywords:mathematical reasoning, solving problem, intuitive.

Abstract

Penelitian ini bertujuan untuk mengetahui kevalidan, kepraktisan, dan keefektifan pengembangan lembar kegiatan siswa (LKS) matematika berdasarkan masalah open-ended pada materi SPLDV.Penelitian ini dilakukan di SMK PGRI Wonoasri pada kelas X Multi Media dengan mengacu pada model pengembangan 4D sampai pada tahap ketiga, yaitu define, design, and develop.Instrumen yang digunakan dalam penelitian ini diantaranya adalah lembar validasi LKS untuk mengetahui kevalidan LKS yang dikembangkan lembar validasi angket respon untuk mengukur kepraktisan LKS, dan soal soal tes hasil belajar siswa untuk mengukur keefektifan LKS. Hasil dari penelitian adalah sebagai berikut : 1) LKS yang dikembangkan memenuhi kriteria kevalidan dengan hasil rata-rata yang diperoleh dari angket validasi LKS mencapai 88,2% 2) LKS yang dikembangkan memenuhi kriteria kepraktisan dengan hasil rat-rata yang diperoleh dari angket respon siswa pada uji coba lapangan mencapai 92%3) LKS yang dikembangkan memenuhi kriteria keefektifan dengan hasil rata-rata yang diperoleh dari tes hasil belajar siswa pada uji coba lapangan mencapai 77,4%. Berdasarkan hasil penelitian tersebut dapat disimpulkan bahwa LKS Matematika berdasarkan masalah open-ended pada materi SPLDV kelas X Multi Media tahun ajaran 2018/2019 yang dikembangkan oleh oleh peneliti layak digunakan dalam pembelajaran.

Abstract

Berpikir kritis matematis merupakan salah satu faktor penting dalam menyelesaikan masalah matematika, untuk meningkatkan  berpikir kritis siswa diperlukan pembelajaran yang tepat. Brain based learning merupakan salah satu alternatif pembelajaran yang mampu mengoptimalkan sistem kerja otak siswa sehingga dapat membantu siswa untuk memahami, menyelesaikan masalah dan menerapkan materi tersebut. Sehingga jika sistem kerja otak siswa bisa optimal maka dapat berpikir kritis dalam menyelesaikan masalah matematika.Kata kunci: Brain Based Learning, Berpikir Kritis Matematis

Abstract

Education is a common activity in human life. Every life in society has an educational process, both intentionally and unintentionally. In studying mathematics, students are required to be able to relate mathematical concepts that will later be useful in the process of solving problems. Students are expected to be able to master and apply mathematics subjects to daily life. This study aims to describe what mistakes male and female students often make in solving problems to build a flat side room. This study aims to describe what mistakes are often made by male students and. women in solving problems building flat side rooms. This type of research is descriptive qualitative. The subjects of this study were 2 female students and 2 male students of class VIII-A of SMP N 1 Sawahan for the 2021/2022 school year. Data collection techniques include written test questions and interviews. The data validity technique uses triangulation techniques, which aim to compare test result data and interview results. The data analysis technique uses three stages, namely data reduction, data presentation and conclusion.
