This preliminary study aims to analyze the mastery of mathematical communication skills of class VIII students in junior high school in Bandung regency of triangular and rectangular flat building material. In this preliminary study, the research method used is a qualitative descriptive method with 5 students of class VIII as a sample and research instruments used are 5 items about the instrument of mathematical communication ability. Based on the observations made on 5 students it is found that mastery of mathematical communication skills owned by grade VIII students in one junior high school in Bandung Regency is still relatively low.

This study aims to analyze in depth the influence of mathematical disposition on mathematical communication ability of junior high school students. The method in this research using a correlational method with quantitative approach. The population of this study is all junior high school students in one of the SMP Negeri in West Bandung amounted to 34 students. Instruments in this study using the test of mathematical communication skills as much as 5 items and the scale of mathematical disposition as much as 23 points of statement scale. The result of this research is student's mathematical disposition influenced by 76,5% then its rest influenced by other factors outside mathematical disposition equal to 23,5%.

This research was motivated by the difficulties of teachers in implementing the 2013 curriculum, especially in the preparation of learning tools. This research was aimed to develop a valid, practical and effective learning tool for VIII grade junior high school students. This type of research was Research and Development with a 4-D model. Data collection instruments in this study were validation sheets, practicality sheets and tests of mathematical communication skills. Data were analyzed using validation criteria, practicality and effectiveness tests. The results obtained from the device validation show that the RPP is valid and the LKPD is quite valid. The practicality test results of small groups and large groups obtained very practical criteria. The effectiveness test can be seen from the percentage of student KKM achievement that is equal to 92% meets the effective criteria and the average difference test (t test) is obtained that tcount> ttable, which is 16.976> 1.677 and the significance value is <0.05. These results indicate that the developed learning tools are effective in improving students mathematical communication skills.

The mathematical communication ability of students is still low. One effort that can be done is to implement Experiences, Language, Pictures, Symbols, Application (ELPSA) framework. The pur pose of this research was to determine students' mathematical communication skills through the application of the ELPSA framework. This research is a descriptive quantitative research. The sub jects were Year 8 students of one of Junior High School in Banda Aceh which consisted of 24 students. Data collection is done through stdeunts worksheet and mathematical communication tests. Data ana lysis was performed by calculating the score of students' mathematical communication in groups and individually using percentage techniques. The results of this research are the mathematical com munication abilities of students in groups during learning with the implementation of ELPSA framework producing high average score. Whereas students' mathematical communication skills after the implementation of the ELPSA framework showed 75% of students met the minimal criteria.

This research is motivated by the low mathematical communication skills of junior high school students in the city of Bandung Regency. This study aims to determine the comparison of the mathematical communication skills of junior high school students in the city of Bandung regency between the learning usingmodels Think Talk Write. The method used in this study is a quasi-experimental method with a pretest-posttest control group design involving two groups and randomly selected classes, at the beginning and end of the study the two classes were given a test. The population in this study were junior high school students in the city of Bandung Regency, while the sample consisted of two randomly selected classes. Obtained class VII A (experimental class) given themodel Think Talk Write and class VII B (control class) is given a scientific approach. The instrument used was a 5-item mathematical communication ability description test, then theability scores mathematical communication students'were analyzed with descriptive and inferential statistics using the help of SPSS 21 software. Based on the results of the study, it was concluded that there were differences in the achievement of students' mathematical communication skills using models Think Talk Write with students who used a scientific approach.

This research aims to describe the students’ mathematical communication ability by using cooperative learning talking stick type. This research conducted at one of junior high school in Asahan-North Sumatera- North Sumatera. This research used posttest experimental class design as the method to obtain data. The indicators used to measure mathematical communication ability in this research arranged in three, as follows: 1) the ability of explaining a mathematical problem into figure; 2) the ability to explain mathematical problem situations by own words; 3) the ability of stating a mathematical problem in writing into mathematical models and doing calculation to solve the problem. The result found from this research is there are the differences in the students’ way of answering the problem even though the learning model and the instrument used is same.

The main purpose of this study to investigate the ability of mathematical communication ofHigh School Students, as a result of learning mathematics through application RealisticMathematics Education (RME). Research design used was a quasi experimental. Subjects inthis study consisted of 70 students of class VII Junior High School, Junior High School on oneof the states in Bandung academic year 2015/2016. Subject determined by purposivesampling techniques, and this study using pretest-posttest design of the control group. Datacollected with a mathematical communication ability test descriptions. Data were analyzedusing parametric statistical tests which is Test Independent Sample T-Test and nonparametrical tests which is Test Mann-Whitney. The results showed that: (1) students wholearn math with RME approach has a better ability mathematical communication of studentswho do not learn math with RME; (2) increasing mathematical communication ability ofstudents who learn with RME better than students who do not learn with RME; (3) students'attitudes toward learning mathematics through RME showed a positive attitude.

The purpose of this study was to analyze and explore the effectiveness of constructivism approaches in improving mathematical communication skills of junior high school students in the city of Paser. The experimental quasi method was used in this study to test the hypothesis of the study. The sample of the study at three junior high schools in Paser City, representing high, medium and low school students.. The instruments used in this study were pre-post test, pre-post questionnaires, and observation. The data were analyzed using independent sample t-tests, paired sample tests, annova tests, and descriptive analysis. The findings of pre-post test and pre-post questionnaire analysis using t-test showed that there were significant differences in group mathematical communication skills using constructivism approach compared to groups using conventional approaches at all achievement levels of high school students (high, simple and low). Based on the observation, it is found that high achievement school students have good mathematical communication skills in mathematical communication, these are identified in many aspects and observation indicators achieved by students during learning.
