Abstract

Tujuan Penelitian ini adalah untuk menganalisis karakteristik learning obstacle yang terjadi pada siswa SMP saat mengerjakan soal kemampuan komunikasi matematika dengan materi bangun datar. Jenis learning obstacle yang difokuskan pada penelitian ini adalah ontogenic obstacle, didactical obstacle dan epistemologi obstacle. Metode Penelitian ini adalah kualitatif deskriptif  dengan 3 sampel siswa (dari kemampuan rendah, sedang dan tinggi) dari salah satu sekolah di Kota Cimahi, instrumen penelitian ini berupa seperangkat tes pada materi bangun datar dan pedoman wawancara. Hasil dari penelitian ini diperoleh bahwa karakteristik learning obstacle yang terjadi kebanyakan epistemologi obstacle yaitu keterbatasan koteks yang dimiliki siswa, sedangkan didactical obstacle hanya sebagian kecil yang mengalaminya dan tidak ada siswa yang mengalami ontogenic obstacle dalam menyelesaikan soal

Abstract

This study aims to determine the increased ability of mathematical generalization and self-confidence of students junior hight school with Methaporical Thinking approach. The research method used is an experimental method involving 2 classes, namely experimental class and control class. The sample of this study was chosen randomly with the number of samples were 30 students of class XII at SMP RAHAYU. And elected class 7-1 as experimental class and class 7-2 as control class. In each data collection each student will be given the same pretest and postes. Intrument used is a test of mathematical generalization ability and scale of confidence. From the calculation and hypothesis test, it can be concluded that the improvement of mathematical generalization ability of the experimental class is significantly better than the control class, then most of the students who get the learning with methaporical thinking had better self confidence than ordinary learning.

Abstract

This study aims to determine the ability of students mathematical communication skills of junior high school students in the material of One Variable Linear Equation and Inequality. The study was conducted on seventh grade students in one of the junior high schools in Cimahi as many as 37 students who were taken 6 random samples based on the results of the location of errors done by students in different criteria according to Watson's error. The research approach used is qualitative with descriptive method. The instrument used is a matter of mathematical communication that has been validated. Tests carried out by students were examined for the type of error based on the Watson category and an analysis of error answers was carried out. The results showed that based on the percentage of the types of errors students who had completed mathematical communication problems based on the category of errors according to Watson were incorrect data / ID errors included in a small error of 21%, improper procedure errors IP) is included in a high error of 46%. Omitted conclusions (OC) fall into a fairly low error of 3%. Errors in data missing (ommited data / OD) which is equal to 21%, Error hierarchical problem (SHP) problem is 7%. While conflict response levels (response level conflict / RLC), indirect manipulation (UM), and also errors other than the seven above other / AO) are 0% each, including very low errors.

Abstract

The purpose of this study is to analyze and describe the ability of mathematical connections in terms of self efficacy in Triangle and Segiempat material which is guided by the mathematical connection and self efficacy indicators. This research method is descriptive research by using qualitative approach. This research was conducted in SMP Negeri in Kabupaten Bandung. The subject of this research is the students of class VIII consisting of 20 students. The instrument used in this research is a matter of mathematical connection test, non test in the form of Self efficacy questionnaire, and interview. Based on the conclusions from the results of research and discussion in general can be concluded that the ability of mathematical connections in terms of self efficacy of junior high school students is the difference in the ability of mathematical connections at each level of student self efficacy. The ability of mathematical connections in review of the student's self efficacy indicator that is not met is to apply mathematics in other fields or in everyday life, to understand the equivalent representation of a mathematical concept or procedure, to seek the relationship of various representations of concepts, processes, or mathematical procedures, procedures with other procedures in the equivalent representation. Then for the Student Self Efficacy, in completing each statement given the average student replied that students are afraid of being wrong to work on the problem, and students feel unsure that the student can do the questions given
