Abstract

This study aims to examine the improvement of students representation ability of Class VIII on the material of two-variable linear equation system through contextual approach. This type of research is classroom action research. The method of this research is qualitative descriptive. This research was conducted on Grade VIII-A students of SMP Mahardhika in the academic year 2017/2018 with 39 students. The instrument used is a students mathematical representation test, cycles I and II tests (after giving of action), and an observation sheet for teachers and students to conditions of action implementation. The results of this study indicate that the aspect of mathematical representation ability of students has increased because of the problems tested in each test, the more students who score above the KKM.

Abstract

This research is based of low mathematics creative thinking ability from students in Vocassional High School in order to be needed study method to solve that problem. Alternatife of study method and  strategy is use Mind Mapping method by Thinking Aloud Pair Problem Solving (TAPPS) strategy. The purpose of this research is to identify weather achievement of mathematics creative thinking ability of students in High School through use Mind Mapping method by Thinking Aloud Pair Problem Solving (TAPPS) strategy is better than use convensional study. The population in this study were vocational high school students in Bandung, while the sample was SMK MAARIF Cicalengka and selected two classes randomly from all of the existing XI class. Then from the two classes are assigned randomly into the experimental class and control class. The experimental class  received learning get Mind Mapping Method by Thinking Aloud Pair Problem Solving (TAPPS) strategy and control class gained regular learning. The instrument used is the test of creative thinking ability mathematically. Based of the calculation and hypothesis test concluded that the achievement of creative thinking ability of mathematic of students who get Mind Mapping Method with Thinking Aloud Pair Problem Solving (TAPPS) Strategy is better than those who get regular learning.

Abstract

The purpose of this research is to find the correlation between mathematical generalization skill and student’s self-concept in learning activities by using learning strategy based on VBA’s Microsoft Excel. Experimental method is used in the research with 2 different classes. The first class is given by VBA Microsoft Excel learning based, while the other class is given common learning method. In addition, the data sample used in this research are all Junior High School in Cimahi, one school is selected randomly and SMP Negeri 4 Cimahi has been selected. The Sample chosen is the 8th grade pupils which selected randomly. One class as experiment class, and the other is controlled class. The result of the research is obtained from mathematical generalization skill test instrument of phytagoras and self-concept skill inquiry as non-test instrument. Mathematical generalization skill post-test result and final inquiry are analyzed by using Spearman to find the correlation. The result shows that there is a correlation between mathematical generalization skill and student’s self-concept in learning mathematics.

Abstract

The balance between cognitive and mathematical affective abilities is very important to be mastered by students in order to face future challenges. Background of the research is based on the students’ low ability of mathematical problem solving and mathematical learning activeness. The purpose of this research is finding the relation between students’ mathematical problem-solving ability and students’ mathematical learning activeness by using Realistic Mathematics Education approach using GeoGebra. The method in this research is the experimental research in the form of pre-test-post-test Control Group Design. In addition, the population for this research is the entire Public middle schools (SMP Negeri) in West Bandung regency. From all public middle schools in West Bandung, a school named SMP Negeri 3 Batujajar is randomly selected, and two classes of the 1st-gradestudents of the school are selected as the research sampling data. The first class becomes an experimental class which gains learning using GeoGebra assisted realistic mathematics educational approach and the other class gets common learning. The result of the research shows that there is a more positive relationship between mathematical problem-solving ability and mathematical learning activeness of learning by using Realistic Mathematics Education approach with GeoGebra rather than using common learning. In addition, the approach gives positive impacts, such as more interactive learning, understanding concepts, and more meaningful learning.
