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. Based on the work indicator, it is concluded that the mathematical representation ability of grade VIII-A students of SMP Mahardhika Batujajar on two-variable linear equation system can be improved through contextual approach.

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

This study intended to studied student’s ability to mathematical creative thinking and mathematical disposition of student who receive contextual approach compared to those who receive regular learning. Method use in this study is Experiment Method.  Population in this study is the students of Junior High School in West Bandung Regency while the sample is SMP Negeri 1 Cihampelas and two classes are randomly chosen from all existing VII grade. From those two classes randomly appointed which will be the experiment class and control class. Experiment Class receive learningwith contextual approach while Control Class receive regular learning. Instrument used are mathematical creative thinking ability test and mathematical disposition scale. From the result and hypothesis testing concluded that increasing ability to mathematical creative thinking and mathematical disposition of students who receive contextual approach learning are better than those that receive regular learning.

Abstract

The problem that becomes background of this research, the abilitity of mathematical understanding of students is still lowThe purposes of this research are to know the influences of the use of active learning model type Everyone is a Teacher Here on raising the abilitity of mathematical understanding of students and to know students response of mathematics learning by using mathematics learning model. The method that is used in this research is Experimental, with research design Non-Equivalent Control Group Design. The research is done in SMP N 1 IBUN. The population in this research is all of students of  class VII-C as experiment class and class VII-B students as control class that is choosed randomly. And the instrument that is used is mathematical understanding test, observation sheet of students learning activity and questionnaire. In this research obtained qualitative data and quantitative data. Based on analysis of the result of the abilitity of mathematical understanding test concluded that active learning model type Everyone is a Teacher Here has positive effect on abilitity of mathematical understanding of students in mathematics learning. While based on analysis of observation sheet and questionnaire concluded that there is raising students learning activity in mathematics learning by using active learning model type Everyone is a Teacher, and the students give positive response on mathematics learning by using active learning model type Everyone is a Teacher Here
