Analisis Kemampuan Komunikasi Matematik Siswa SMP Mutiara 1 Bandung pada Materi Bentuk Aljabar

The purpose of this study was to describe the mathematical communication skills of students of SMP 1 Bandung Junior High School class VII and examine errors in solving test questions regarding the material in the form of algebra. The research method used is the description method. The subject of the research was conducted on 29 students of Grade 1 Pearl Junior 1 Bandung Bandung. The test questions given are in the form of 6 questions. The results showed that mathematical communication skills as a whole were moderate and there were 1 indicator that entered the criteria very well, namely for indicators to rewrite information in the form of images into the language of mathematics. (Well); indicators state the problem of mathematical models of story forms into mathematical symbols, (Good); the indicator states what is known and asked according to the mathematical formula (Good), the indicator completes what is known and what is asked daily events using mathematical formulas (Good). And 1 indicator which includes sufficient criteria, namely the indicator states the completion of the mathematical model of drawing with the right solution idea. And it can be seen that the average score of all questions from all students is included in the good criteri

Meningkatkan Kemampuan Berpikir Kreatif Matematis dan Kemandirian Belajar Siswa SMP melalui Pendekatan Saintifik Berbasis Etnomatematika

This research is motivated by the lack of ability to think creatively Mathematically junior secondary students. This research aims to determine differences in achievement and increase the ability of creative thinking and independent learning as well as the association between mathematics student who obtained the usual scientific approach to obtaining scientific approach based etnomatematika. This research method is experimental design with pretest posttest control group design in this study population eighth grade students in one of the Junior High School in Bandung, the sample was taken two classes of ninth grade there. Instruments in this study is a test description of critical and creative thinking skills as much as 5 mathematical problems. Based on the results of the study are Differences in Achievement and improvement Ability Creative Thinking Mathematically junior high school students are learning to use PendekatanSaintifik usual with the use Approach Scientific based etnomatematika, and there is no difference Independence Learning student learning using the approach Scientific with the gain approaches saintif based Etnomatematika and are associated antarakemampuan Creative Thinking Mathematically students with learning independence student learning using etnomatematika-based Scientific Approach
