Improvement of Mathematical Communication Skills and Student Learning Motivation Through Realistic Mathematics Education Approaches

This study aims to see students 'mathematical
communication skills and student learning motivation through a
realistic mathematics education learning approach, describing
the process of students' answers in solving mathematical
communication problems. This study is a quasi-experimental
research . The research subjects were students of class VIII
SMP Negeri 1 Binjai. Then two classes were randomly selected.
The experimental class was given PMR learning treatment and
the control class with ordinary learning. The instruments used
consisted of: a test of mathematical communication skills and a
student motivation questionnaire.The purpose of this study was
to determine whether: improvement in mathematical
communication skills of students who obtained learning with the
Realistic Mathematical Approach (PMR) was higher than
students who received Conventional learning, increased learning
motivation of students who obtained learning with PMR higher
than students who obtain Conventional learning, there is an
interaction between learning models with students' initial
mathematical abilities to increase students' mathematical
communication skills, there is an interaction between learning
models with students' initial mathematical abilities towards
increasing student motivation. The results of this study have
explained in detail the research procedures for improving
communication skills and student motivation through a realistic
mathematics education approach.
