EFEKTIVITAS PENGGUNAAN MODEL PEMBELAJARAN MATEMATIKA REALISTIK TERHADAP KEMAMPUAN PEMAHAMAN KONSEP TEORI GRAF BERBANTUAN MATLAB PADA MATA KULIAH MATEMATIKA DISKRIT

Abstract

This study aims to determine the The effectiveness of realistic mathematics learning on the ability to understand graph theory concepts assisted by MATLAB in discrete mathematics courses for students STKIP Budidaya Binjai. This research was conducted at STKIP Budidaya Binjai on fourth semester students. Jenis penelitian yang digunakan dalam penelitian ini adalah penelitian eksprimen dengan  desain  penelitian pre-test  and  post-test  control  group  design. The population in this study was all fourth semester students of STKIP Budidaya Binjai. In the experimental class, the treatment was given using realistic mathematics learning and in the control class, conventional learning was used with pretests and posttests. The Matlab program can be used as a tool in learning discrete mathematics courses, especially graph theory material with mastery of concepts, theories, and procedures. The data in this study were analyzed using a simple regression test. Matlab software is used to draw vertices, graph edges and graph components. Data analysis techniques using SPSS-Version 18 software with linear regression tests. From the results of the average test scores for understanding mathematical concepts of students in the experimental class before and after learning were 46.96 and 79.96. While for the control class 42.10 and 64.56. The results of the hypothesis test with a significance value of α = 5% then H0 is rejected and Ha is accepted. So the results of this study show that there is "effectiveness of the realistic mathematics learning model on the ability to understand the concept of graph theory assisted by MATLAB in discrete mathematics courses for students of STKIP Budidaya Binjai.
