Abstract

Penelitian ini bertujuan untuk menganalisis kemampuan penalaran dan kemandirian belajar pada materi persamaan garis lurus siswa SMP. Metode penelitian ini menggunakan metode deskriptif kualitatif. Tempat penelitian dilaksanakan di SMP Negeri 5 Cimahi pada kelas VIII semester ganjil tahun ajaran 2017-2018. Populasi penelitian ini adalah siswa kelas VIII SMP Negeri 5 Cimahi pada materi Persamaan Garis Lurus. Subjek penelitian adalah siswa kelas VIII E. Untuk memperoleh data penelitian digunakan instrumen berupa tes soal uraian dan angket kemandirian belajar. Hasil penelitian didapat kesimpulan: (1) tingkat kemampuan penalaran matematis siswa dalam penyelesaian masih level rendah; (2) kesulitan siswa pada umunya belum memahami soal dan prakonsep masih rendah; (3) siswa belum tertanam rasa belajar secara mandiri. Kata kunci: kemampuan penalaran matematis, kemandirian belajar.   ABSTRACT This study aims to analyze the ability of reasoning and self-regulated learning on the material of equations of straight lines of junior high school students. This research method using qualitative descriptive method. This research is conducted in SMP Negeri 5 Cimahi in Grade VIII of academic year 2017-2018. The population of this study is the students of class VIII SMP Negeri 5 Cimahi who have studied the material of the equation of straight line. The subject of the research is the students of class VIII E. To obtain the research data used the instrument in the form of test description and questionnaire self-regulated learning. The results of the research concluded: (1) the level of students mathematical reasoning ability in the problem solving is still low level; (2) students difficulties in general have not understood the problem and the preconception is still low; (3) students have not embedded the sense of learning independently. Keywords: mathematical reasoning ability, self-regulated learning.

Abstract

Penelitian ini bertujuan untuk mengetahui tingkat kemampuan penalaran matematis dan resiliensi siswa SMA untuk mengetahui kesalahan siswa dalam menyelesaikan soal statistika. Metode penelitian ini adalah deskritif kualitatif. Tempat penelitian dilaksanakan di SMA Negeri 4 Cimahi jurusan IPA kelas XII- MIA 3 semester 1. Penelitian ini tergolong dalam penelitian deskriptif kualitatif yang berupaya untuk mendeskripsikan analisis kesalahan siswa dalam mengerjakan dan menyelesaikan soal statistika. Populasi penelitian adalah seluruh siswa SMA kelas XII di kota Cimahi jurusan IPA. Untuk memperoleh data penelitian digunakan instrumen berupa tes diagnostic soal statistika dan angket resiliensi siswa. Hasil penelitian didapat kesimpulan: (1) tingkat kemampuan siswa pada soal kemampuan penalaran masih rendah; (2) kesalahan siswa pada umunya belum memahami soal dan belum memiliki daya nalar yang baik; (3) siswa masih perlu ditanamkan mathematical resilience. Adapun solusi untuk mengatasi hambatan tersebut melalui latihan atai drill soal secara terstruktur dan memberikan soal yang beragam sebagai bahan untuk berlatih. Guru  mencoba menggunakan metode yang berbeda setiap pertemuan di kelas agar siswa tidak mudah jenuh dan berlatih berpikir dan memiliki penalaran yang tinggi.

Abstract

This research is a study to analyze the ability of mathematical connections and self-confidence in the flat-side space material for junior high school students. This research used a qualitative descriptive method. The study was conducted at 47 Bandug Junior High School in 9th grade students of SMPN 47 Bandung who had studied in a flat side room. The research subjects were ninth grade F. The data were collected in the form of a description of the test instrument and self-confidence questionnaire. The results of the study concluded: 1) the level of students' mathematical connection skills in the settlement pointed at good categories; 2) students have mastered the materials so that they could understand problems and concepts well; 3) students already have had good self-confidence.

Abstract

The purpose of this study was to determine the increase in creative thinking skills of junior high school students who use learning by using the problem posing approach and the scientific approach to classroom learning, especially in mathematics. Quasi experiment is this type of research with the control group pre test and post test design. The research was conducted at one of the junior high schools in Cimahi City. As many as 62 students of class VII being sampled in this study consisted of 30 students in the experimental class with problem posing learning and 32 students in the control class with scientific learning. The testing in this study uses IBM SPSS version 22 software. The conclusions from the results of this study are 1) Increasing the ability of mathematical creative thinking by using a problem posing approach better than the scientific approach, 2) A problem posing approach if it is well planned for effectiveness when learning takes place, and 3) Students who are inaccurate in solving the problem of the ability to think creatively because they do not understand the problems asked in the questions. This can be seen from several responses of students who are incomplete in giving responses

Abstract

Mathematics is a science that can not be separated from other science as well as in everyday life. The ability of mathematical Connection aims to connect the mathematics with other disciplines and also daily life so that math can be more meaningful. This study aims to determine the ability of mathematical connections of junior high school students VIII class in one of junior high school in Bandung on Comparable material reviewed through gender. Subject consists of 35 students. In addition, the discussion on the mathematical connection ability for junior high school students from the difference of gender, between students and students in terms of ability penyimannya. The understanding of the mathematical connection capability rests on the concept of "socio-cultural construction" that there is a difference between men and women, resulting in their respective roles and duties. While based on the results of his research states that the difference of ability between male and female students and the results showed that the mathematical connection ability of female students is much better that is with an average of 3.71 from the students 3.59. In addition to gender factors are also found other factors that can affect the achievement of the ability of the connection of the readiness of students and teachers to learn, basic skills of students and basic knowledge of mathematical concepts
