Abstract

Beberapa alasan perlunya kemampuan representasi yaitu untuk membangun konsep dan berpikir matematis, serta untuk memiliki kemampuan pemahaman konsep baik yang dapat digunakan dalam pemecahan masalah.Penelitian ini merupakan penelitian kuasi eksperimen yang bertujuan untuk menganalisis perbedaan kemampuan representasi matematis antara siswa yang mendapatkan pembelajaran Contextual Teaching and Learning dan Discovery Learning. Populasi pada penelitian ini adalah seluruh siswa kelas VIII SMP Negeri 2 Garut. Teknis pengambilan sampel menggunakan Purposive Sampling dengan sampel sebanyak dua kelas. Diperoleh kesimpulan bahwa terdapat perbedaan kemampuan representasi  matematis siswa antara yang mendapatkan model pembelajaran Contextual Teaching and Learning  dan model pembelajaran Discovery Learning, kualitas peningkatan kemampuan representasi  matematis siswa yang mendapatkan model pembelajaran Contextual Teaching and Learning dan Discovery Learning berinterpretasi sedang, dan sikap siswa terhadap model pembelajaran Contextual Teaching and Learning dan Discovery Learning berinterpretasi cukup.Some of the reasons for the need for representational skills are to build concepts and think mathematically, as well as to have good conceptual understanding skills that can be used in problem-solving. This research is a quasi-experimental study that aims to analyze the differences in mathematical representation abilities between students who receive Contextual Teaching and Learning and Discovery Learning. The population in this study were all eighth-grade students of SMP Negeri 2 Garut. The sampling technique used was purposive sampling with a sample of two classes. It was concluded that there were differences in students' mathematical representation abilities between those who received the Contextual Teaching and Learning learning model and the Discovery Learning learning model, and the quality of improving the mathematical representation ability of students who received the Contextual Teaching and Learning and Discovery Learning learning models with moderate interpretation, and student's attitudes towards the learning model. Contextual Teaching and Learning and Discovery Learning have sufficient interpretation.

Abstract

Kemampuan pemecahan masalah matematis merupakan salah satu kemampuan yang penting untuk dikembangkan dan dimiliki siswa. Beberapa penelitian menunjukkan bahwa kemampuan pemecahan masalah matematis yang dimiliki oleh siswa masih rendah. Tujuan penelitian ini adalah untuk menganalisis kesulitan kemampuan pemecahan masalah matematis siswa pada materi sistem persamaan linear dua variabel. Penelitian ini dilakukan di SMP IT Al-Fadhilah Kp. Pasirkiamis Desa. Pasirkiamis Kec. Pasirwangi Kab. Garut. Penelitian ini menggunakan pendekatan kualitatif dengan metode analisis deskriptif yang melibatkan 3 siswa sebagai sampel (teknik simple random sampling). Instrumen tes kemampuan pemecahan masalah matematis siswa yang digunakan sebanyak 4 butir soal berbentuk uraian. Berdasarkan hasil penelitian dan pembahasan dapat disimpulkan bahwa kesulitan yang paling banyak dilakukan siswa yaitu pada tahap membuat pemodelan matematika dan menerapkan strategi untuk memecahkan masalah pemodelan matematika. Siswa belum melakukan langkah-langkah penyelesaian soal dengan lengkap, karena siswa belum menerapkan prinsip menyelesaikan soal masalah matematis pada materi sistem persamaan linear dua variabel dan belum terbiasa memeriksa kembali jawaban dengan teliti. Mathematical problem-solving ability is one of the important skills to be developed and owned by students. Several studies show that students' mathematical problem solving is still low. The purpose of this study was to analyze the difficulty of students' mathematical problem-solving abilities in the variable system of linear equations of two materials. This research was conducted at SMP IT Al-Fadhilah Kp. Pasirkiamis Village. Pasirkiamis Kec. Pasirwangi District. arrowroot. This study uses an approach with a descriptive analysis method involving 3 students as a sample (simple random sampling technique). The test instrument for students' mathematical problem-solving abilities used as many as 4 items about the description. Based on the results of research and discussion, it can be said that the ease with which most students do is at the stage of making mathematical modeling and applying strategies to solve mathematical modeling problems. Students haven't done the steps to complete the problem completely, because students have not applied the principles of solving mathematical problems to the material for systems of linear equations of two variables and are not accustomed to re-examining answers carefully.

Abstract

Self-regulated learning merupakan salah satu faktor penting dalam pembelajaran untuk mengendalikan diri dalam berpikir maupun bertindak. Tujuan penelitian ini adalah untuk mengetahui pengaruh self-regulated learning terhadap hasil belajar matematika siswa. Metode penelitian ini adalah deskriptif kuantitatif dengan jenis korelasional dan expost facto. Sampel penelitian terdiri dari siswa kelas VII dan VIII pada salah satu SMP Negeri di Kota Serang dengan rincian 20 siswa kelas VII dan 20 siswa kelas VIII. Instrumen yang digunakan berbentuk non-tes yang berisi butir positif dan negatif. Teknik analisis data dilakukan dengan analisis inferensial menggunakan software SPSS 25.00. Hasil penelitian menunjukkan bahwa tidak terdapat pengaruh self-regulated learning atau kemandirian belajar terhadap hasil belajar matematika siswa. Self-regulated learning is one of the important factors in learning to control oneself in thinking and acting. The purpose of this study was to determine the effect of self-regulated learning on students' mathematics learning outcomes. This research method is descriptive and quantitative with correlational and exposed facto types. The research sample consisted of students in grades VII and VIII at one of the public junior high schools in Serang City with details of 20 students in class VII and 20 students in class VIII. The instrument used is in the form of a non-test containing positive and negative items. The data analysis technique was carried out by inferential analysis using SPSS 25.00 software. The results showed that there was no effect of self-regulated learning or independent learning on students' mathematics learning outcomes.

Abstract

Kemampuan komunikasi matematis masih rendah. Perlu analisis untuk mendeskripsikan kemampuan komunikasi matematis, diantaranya ditinjau dari self regulated learning siswa pada materi sistem persamaan linear dua variabel. Penelitian dilakukan secara kualitatif dengan metode deskriptif. Subjek penelitian yaitu tiga siswa kelas VIII SMP di Cimuncang, dipilih secara purposive. Teknik pengumpulan data menggunakan tes kemampuan komunikasi matematis, angket self regulated learning siswa, dan wawancara. Teknik analisis data dilakukan dengan reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa dua subjek dengan kategori self regulated learning tinggi, salah satunya belum memenuhi keempat indikator yang diaplikasikan dalam tes kemampuan komunikasi matematis. Sedangkan satu lainnya mampu memenuhi dua indikator. Satu siswa dengan self regulated learning sedang belum memenuhi satupun indikator kemampuan komunikasi matematis. Self regulated learning menjadi faktor yang perlu diperhatikan terkait dengan kemampuan komunikasi matematis siswa.Mathematical communication skills are still low. An analysis is needed to describe mathematical communication skills, including in terms of students' self-regulated learning of the material of a two-variable linear equation system. The research was conducted qualitatively with a descriptive method. The research subjects were three grade VIII junior high school students in Cimuncang, selected purposively. Data collection techniques used mathematical communication skills tests, student self-regulated learning questionnaires, and interviews. The data analysis technique was carried out by data reduction, data presentation, and conclusion. The results showed that in two subjects with a high self-regulated learning category, one of them did not meet the four indicators applied in the mathematical communication ability test. While the other one can meet two indicators. One student with moderate self-regulated learning has not met any of the indicators of mathematical communication skills. Self-regulated learning is a factor that needs to be considered related to students' mathematical communication skills.
