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.

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.

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.

This research is to find out the mathematical communication skills of VIII junior high school students about building a flat side space. This research method is a qualitative descriptive study. The subject of this research is 18 students in one junior high school in Bandung regency. The test instrument used is a description form. The indicator used in this study there are 5 indicators of mathematical communication ability, namely expressing ideas, situations and relations with images, expressing mathematical situations or everyday events into mathematical models, explaining and making questions of mathematical problems, low indicators only obtain an average percentage averaged 12%, based on the results of calculations using the Microsoft Exel application the overall student communication skills of these five indicators are still low below 50% which is only 44%.

This article is derived from the research result entitled “The Application of Problem Solving Approach in Improving Junior High School Students’ Mathematical Communication and Disposition Skill”. The research is purposed to see and analyze if there are some improvements in mathematical communication and disposition skill achievement of the students who have been treated using problem solving approach compared to the students who are still treated using conventional approach. The population of the research is all students at a junior high school in Subang regency. Out of these students,  40 students of class VIII D were chosen randomly as the experiment class, and 41 students of class VIII C have also been randomly chosen as the control class. The data in this research have then been analyzed using parametric and non-parametric statistic. The result of this analysis has shown that the achievement of experiment class students’ mathematical communication and disposition skill is better than the achievement of the control class students. The experiment class students’ mathematical disposition is also better than those of the control class. Lastly, the result also shows that there is some kind of correlation between the mathematical communication and mathematical disposition on the level of medium.

AbstractThis research aimed (1) describe the implementation of learning in the classroom with the Quantum Learning model, (2) describe the students' written mathematical communication skills with Quantum Learning, and (3) describe the effectiveness of applying the Quantum Learning model to the written mathematics communication skills of junior high school students class VIII. The research was conducted in the even semester of the 2019/2020 school year in class VIII of SMP Muhammadiyah 2 Malang. This research is a type of descriptive research with quantitative methods. The initial stage of the research is the planning stage starting from determining the location and time of the study up to the validation of the research instruments used. The next stage is the implementation stage which is held three times by giving a description test to measure the ability of written mathematical communication at the third or final meeting. The last step is analyzing data obtained from the field. The data analysis technique used descriptive statistics. The results showed the average overall implementation of learning was in the good criteria of 83.92%. The ability of written mathematics communication in grade VIII A students of SMP Muhammadiyah 2 Malang is a very good criterion of 3.04. Therefore, it can be concluded that the application of the Quantum Learning model is effective to the written mathematics communication of junior high school students, especially in class VIII A.Keywords: Effectiveness, Quantum Learning, The implementation of learning, written mathematics communication.
