Then, the data were analyzed by using statistic and descriptive analysis.

was collected by using a reading test in the form of multiple choices and creativity questionnaires. In sustaining the research result, the data.

This research was an experimental research consists of four classes as population and one class taken as sample by using purposive sampling technique. The aims of this research was to find out whether learning cell has an effect toward students’ reading ability at the eight year students of SMPN 4 Lingsar Lombok Barat in The Academic Year of 2016/2017. As for the results of the analysis of the data shows that the 1) the ability of understanding the concept of students who use Realistic mathematics education approach better than students who use scientific approach, 2) mathematical reasoning ability of students using Realistic mathematics education approach better than students who use scientific approach, 3) there is a connection between the understanding of mathematical concepts and reasoning of students. The data analysis used t test with two samples and test the correlation with significance level 0.05. Data collection techniques was in the form of test result data post test as the learning outcomes of students. between students who learn to use Realistic mathematics education approach with scientific approach, 3) know the difference between the understanding of mathematical concepts and reasoning of students. The purpose of this research is to 1) know the comparison the ability between students who learn to use Realistic mathematics education approach with scientific approach, 2) know the comparative ability of reasoning mathematically.


This article discusses the application of Realistic Mathematics Education approaches against the ability of mathematical reasoning and understanding of the students.
