The Influence of Realistic Mathematical Approach toward Students’ Mathematical Connections Ability at Public Primary School 105366 Sei Nagalawan Serdang Bedagai.

Abstract

The aims of this study are to examine: the influence of the Realistic Mathematical Approach toward students’ Mathematical Connection Ability of grade V at Public Primary School 105366 Sei Nagalawan and the comparison of Realistic Mathematics Approach with Conventional Learning on the Mathematical Connection Ability. This research is a quasi-experimental study. The population in this study is all fifth grade students of Public Primary School 105366 Sei Nagalawan, consisting of two classes with the number of 55 students. Class V-A, 27 students is as an experimental class using the Realistic Mathematics Approach while the V-B, 28 students is as the control class using Conventional Learning. The instrument used consisted of: preliminary math ability test and mathematical connection ability test. The instrument is stated to have fulfilled the requirements of content validity, and reliability coefficient. The data are analyzed by Simple Regression Analysis Test. Before using Simple Regression Analysis Test, firstly the homogeneity and normality are tested in this study with a significant level of 5%. The average score of students' mathematical connection ability taught with realistic mathematics learning is 79.6 and the average score of mathematical connection ability taught with conventional learning is 72.0. Based on the analysis, the results of the study are: (1) there is an influence of the Realistic Mathematical Approach toward students’ mathematical connection ability of fifth grade at Public Primary School 105366 Sei Nagalawan, (2) the mathematical connection ability of students who obtain a realistic mathematical approach is higher than students who obtain conventional learning.

Keywords: Realistic Mathematical Approach, Mathematical Connection Ability.
