Abstract

Penelitian ini bertujuan melihat adakah pengaruh positif self confidence siswa SMP terhadap kemampuan berpikir kritis matematis. Subjek penelitian yang diambil 30 siswa kelas IX di salah satu SMP swasta di Kota Cimahi. Metode yang digunakan pada penelitian ini yaitu metode korelasional dengan pendekatan kuantitatif. Instrumen dalam penelitian ini meggunakan tes kemampuan berpikir kritis matematis dan angket self confidence. Tes kemampuan berpikir kritis matematis terdiri dari 4 butir soal yang diadopsi dari Yulia (2015) dan angket self confidence terdiri dari 41 skala pernyataan yang diadopsi dari Sumarmo (2015) dengan indikator : a) percaya kepada kemampuan sendiri, tidak cemas, merasa bebas, dan bertanggung jawab atas perbuatannya. b) bertindak mandiri dalam mengambil keputusan. c) Memilih konsep diri yang positif, hangat dan sopan, dapat menerima dan menghargai orang lain. d) memiliki konsep diri yang positif, hangat dan sopan dapat menerima dan menghargai orang lain. e) berani mengungkapkan pendapat dan memiliki dorongan untuk berprestasi. f) saya mengenal kelebihan dan kekurangan diri sendiri. Hasil dari penelitian ini menunjukkan self confidence siswa tidak memiliki pengaruh terhadap kemampuan berpikir kritis matematis. Berdasarkan analisis lanjut penyebab self confidence yang kurang pada siswa dalam penelitian ini yaitu tidak ada motivasi siswa ketika menyelesaikan soal matematika. Jika siswa tidak memiliki motivasi dalam menyelesaikan soal matematika maka siswa itu tidak akan berani mengungkapkan pendapat dan memiliki dorongan untuk berprestasi (indikator self confidence). Yang dapat mempengaruhi siswa terhadap kemampuan berpikir kritis yaitu kemauan dalam belajar dan menyelesaikan soal matematika, motivasi belajar dan self efficacy merupakan faktor-faktor lain yang dapat mempengaruhi kemampuan berpikir kritis siswa.

Abstract

This research aims to know the influence of student’s self-confidence against the ability of mathematical creative thinking of students. Methods used correlational with quantitative approach. Samples taken is as much as 30 students are subjected to an SMP in the city of Cimahi. The instruments used in this research consists of a test and non-test. The results of this research are the self-confidence of students have a positive effect on the ability of mathematical creative thinking of the students of 10.9% and 89.1% influenced by factors other than the self-confidence.

Abstract

This research aims to analyze the mistakes of students in solving mathematical problem solving capability as seen from the extent to which students make mistakes and find out the level of problem-solving ability matematiknya. In this study the methods used i.e. descriptive qualitative approach method. With the population in this research is the entire student MTs in Cimahi and samples in this study i.e. 20 grade VII in one of MTs in Cimahi. The results obtained from the study with the lowest percentage of mathematical problem solving capabilities with indicators identifying the elements of the adequacy of the data, and plan the steps to solve the problem of percentage low of 8% on question No. 2. and indicators make a mathematical model of a real situation in everyday life and doing the calculations to solve problems related to the system of linear equations of one variable of 9% on question No. 4. Less than students are able to create a mathematical model to good use. But in answering the question of students still have not been able to answer the question correctly. Students are only able to answer with mathematical modeling used in the linear equation of one variable. Students haven't been able to operate the linear equation of one variable. Thus, it can be concluded that the ability of problem solving is still classified as low visible from less usually students in making mathematical models and less usually students operate a linear equation in one variable solve tests mathematical problem solving ability.
