This study aims to determine and analyze aspects of students' mathematical communication skills in the material of two-variable linear equations (SPLDV. The study was conducted with a sample of 5 students from 30 populations with different abilities and were taken randomly at one junior high school in Jakarta. used is descriptive qualitative. The research instrument is a test of mathematical communication skills in the form of 5 essay questions and interviews. The results of the tests that have been carried out show the results of communication skills in the medium category because there are 3 questions whose percentage is in the medium category and 2 other questions in the low category It can be seen from the percentage of scores per item, that is question no. 1 has a percentage of 60%. Question no.2 has a percentage of 45%. Question no.3 has a percentage of 40%. Question no.4 has a percentage of 30%. And questions no.5 with the acquisition of a percentage of 25%. Thus, it can be concluded that the ability to communicate The mathematical students on the material of a system of linear equations of two variables are included in the medium category.

Abstract: The objective of this research was to find out students’ learning activity on Linear Equation System of Two Variables subject using Geogebra learning media, to find out if there was an increase in the students’ mathematic communication skills on Linear Equation System of Two Variables subject using Geogebra learning media, and to describe the students’ mathematic communication skills on Linear Equation System of Two Variables subject using Geogebra learning media. This research was conducted at SMP Negeri 1 Ngusikan. Based on the data in the school, the students’ mathematic communication skills was still low, so the use of Geogebra media was expected to increase students’ mathematic communication skills. This research applying qualitative research. The data were collected by tests and interview. To analyzing the students’ mathematic communication skills, the researcher did pre-test and post- test. The result showed that the application of Geogebra learning media can increase the students’ mathematic communication skills on Linear Equation System of Two Variables subject. It proved from the students work process in accordance with the indicators of students’ mathematic communication. Furthermore, the students’ mathematic communication skills will be described by the factors which include the learning process, students’ attitudes and comprehension, also giving question that can measure mathematical communication skills continuously. Keywords: Mathematic communication skills, Geogebra, Linier Equation System of Two Variable

The communication skills of eighth grade junior high school students are catergorized as low. The purpose of this study is to analyze and describe aspects of mathematical communication skill, the research subjects consisted of 10 class students in one of the private schools located in Cimahi. The research method with data collection techniques. From the descript test regarding the two variabel linear equation system of 4 question. The results of this study indicated that students mathematical communication skill are categorized as moderate with a percentage of 42.5 % with the percentage of each item, number one 47.5 %, question number two 60 %, and question number four 32.5 %.

One of the goals of learning mathematics is learning to communicate (mathematical communication). Mathematical communication skills are useful in gaining a better understanding of mathematics and a longer memory of learning mathematics. There are differences in communicating ideas, one of which is caused by differences in personality types. The personality types referred to in this study are extrovert and introvert personality types. This type of research is a qualitative descriptive study which aims to describe the profile of the extrovert and introvert students’ mathematical communication skills in solving the Three-Variable Linear Equation System question. This research was conducted in MAN 2 Jember and the research subject were all students of class X IPA 1. The data collection method used questionnaires and tests. The instruments used were personality type questionnaires, written test question, oral test question, and assessment rubrics. Based on the result of the analysis and discussion, it can be concluded that in general extrovert students and introvert students have similiarities and differences in written mathematical communication skills, namely extrovert students and introvert students alike can write down the information known from the questions, the type of methods to be used to solve the question, and use mathematical symbols. The differences is that introvert students can written down the steps for completion and conclusions, but not for extrovert students, this is because extrovert students end a job even though they have not found a solution. In analyzing a job, introvert students tend to take a long time, are more thorough, rushed, and give up easily in completing work. In general, it can be concluded that extrovert and introvert students can explain mathematical models from known information, state the type of methods to be used to solve problems, and used mathematical symbols. The difference is that extrovert students can explain the completion steps but not introvert students, this is because introvert students are hesitant and pessimistic, so they say cannot explain the completion steps even they not tried it.

This research is a quasi-experimental study that aims to determine the comparison of students' mathematical communication abilities with the cooperative learning model of the NHT and PPT media in class VII SMP Negeri 02 Ngabang. The population in this study were all students of class VII SMP 02 Ngabang consisting of 3 classes. The sample in this study was taken by using the Random Sampling Cluster technique. Class VII A as class I experimental class with 24 students and class VII B as a experimental class II with 24 students. The instruments used were pretest and posttest in the form of description. Data analysis uses the t test with a significance level of 5%. The results showed the average posttest for the NHT class was 72.5 and the average posttest for the PP class was 66.666. From the posttest hypothesis test results obtained t hitung> t tabel (1.9522> 1,667). Because t_hitung> t_tabel, H_0 is rejected and H_a is accepted. This means that students' mathematical communication skills taught with the NHT are better than using Power point media.

ABSTRACTThis research is motivated by the fact that the ability of mathematical communication in Indonesia is low. The models and approaches used in the learning process are one of the supporting factors for learning mathematics in the classroom. This study aimed to analyze SMA 1 Namlea students' mathematical communication skills with realistic mathematics learning assisted by GeoGebra. The research method used is quasi-experimental. WHO researched SMA Negeri 1 Namlea, Buru Regency. The analysis results show that the test instrument is valid and reliable to be used for pretest and posttest. The results showed that the mathematical communication of students who received realistic mathematics learning assisted by GeoGebra was better than students who received realistic mathematics learning without GeoGebra. The results also showed that there was a positive response from students towards learning realistic mathematics with GeoGebra.KEYWORDS: Realistic Mathematics, GeoGebra & Mathematical Communication
