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 study aims to determine the improvement of mathematical communication skills of junior high school students from the influence of contextual approach. This research takes the form of a posttest pretest design that compares the influence of a contextual approach with a conventional approach. This study has a population that is all students of SMP class VII in Cianjur District while the sample is a student of class VII SMP Plus Al-Ittihad Cianjur. The samples were taken at random into experimental groups and control groups. Based on the data in the field, it can be concluded that the effect of improving mathematical communication ability of junior high school students who gain learning using contextual approach is better than conventional learning. Therefore, the effect of improving learning with contextual approach is much better while conventional learning is still very less.

Abstrak Kemampuan komunikasi matematika siswa di SMP 1 Cilaku masiih rendah karena terbatasnya model pembelajaran yang digunakan dalam proses pembelajaran matematika. Proses pembelajaran biasa didominasi oleh guru sehingga membuat siswa merasa jenuh, bosan, dan pembelajaran jadi terasa tidak menyenangkan. Tujuan penelitian ini adalah untuk meningkatkan kemampuan komunikasi siswa kelas Vii SMP 1 Cilaku di Cianjur menggunakan model AIR dan dapat meningkatkan aktivitas belajar siswa, menyampaikan pendapat dalam proses menyelesaikan masalah, keterampilan bertanya dan pengetahuan. Penelitian ini merupakan penelitian tindakan kelas dengan dua siklus pada siswa kelas VII D di SMP 1 Cilaku tahun ajatan 2016-2017 sebagai objek penelitian. Terdapat pengaruh penerapan model pembelajaran AIR. Pembelajaran berjalan dengan kondusif sehingga siswa memberikan respon yang positif dan menunjukkan peningkatan pada setiap siklus. Kata Kunci: model Pembelajaran AIR, komunikasi matematika   The Application of AIR Learning Model to Increase Junior High School Students Mathematical Communication Ability   Abstract Mathematical communication ability among students in Cilaku 1 junior high school still low because of the lack of the learning models in mathematics lesson. The ordinary learning mostly dominated by the teacher that makes the students feel saturated, bored, and makes the lesson considered not fun. The aims of this research are to increase the students’s mathematical communication ability grade VII in Cilaku 1 junior high school in Cianjur by using the AIR model and can increase the students’s learning activity, the clear arguments in completion problem proccess, asking and knowledge skills. This research is action class research trough two cycles with students in D class grad VII in Cilaku 1 junior high school year 2016-2017 as the objects of the research. Significantly had done the lesson using AIR model. The lesson is condusive so that the students give positive response and shows increase in every cycles. Keywords : AIR learning model, mathematics communication

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 ability of mathematical communication is the skill to communicate mathematics that is learned and the skill of using mathematics as a communication tool (mathematical language). Mathematical communication skills are very necessary in learning. Without mathematical communication skills, a person will not be able to deliver statements according to their desire. This qualitative descriptive study aims to describe the level of mathematical communication ability of junior high school students in solving open ended problems with the topic of functional graphs. The method of collecting data through written tests and interviews. Written tests were given to 115 8th grade students of junior high schools in Surabaya, followed by interviews of one student at each level of mathematical communication ability. The results showed 51 people (44%) were at fourth level, 27 people (24%) at third level, 23 people (20%) at second level, and 14 people (12%) at first level. Students at fourth level and third level are equally able to use mathematical language that was accurate and effective, and appropriate in providing the strategies. But it was different in giving the arguments. Students at second level can not provide logical arguments, the mathematical language used was less effective and accurate, and the strategies used were precise but incomplete. Students at first level did not provide the right strategies because the lack of information which contained in the story, did not provide responses more to the stories they have been written, and did not demonstrate the ability to use mathematical language that was  accurate and effective.

The purpose of this study is to examine the achievement and improvement of junior high school students' mathematical communication ability using discovery learning models and props of statistical kenik compared to students who use ordinary learning, and student activities during learning using discovery learning models and props of statistical kenik to take place. This study used a quasi-experimental design. The experimental group obtained learning with discovery learning models and props of statistical kenik and control groups obtained regular learning. The instrument used was a test of mathematical communication ability. The population in this study were all eighth grade students of SMP Negeri 2 Cilamaya Kulon Karawang. With the sample subjects were eighth grade students as many as two classes from the five existing classes randomly selected. The results of this study are: (1) There is achievement and improvement of mathematical communication ability between students whose learning uses discovery learning models and props of statistical kenik compared to students who use ordinary learning; (2) Learning by using discovery learning models and visual aids shows that the learning process is more effective in mathematical problems solving and students can find statistical material concepts.
