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.

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.

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 2013 Curriculum emphasizes on active learning pattern. However, based on the questionnaire spread in junior high school 18 Padang, it was gotten the result that teachers still have difficulty in implementing it, especially in affective competence of confidence. The affective competence of confidence will encourage students to be active in learning process, both in asking questions and expressing opinion. In cooperative learning, students are provided a vehicle to increase their confidence through presenting their discussion result in front of the class. By considering this issue, there is an alternative solution that can be used by teacher, which is example non example method. This method is one of cooperative learning method. Besides that, it can support the implementation of scientific approach and discovery learning model in learning process. The scientific approach and discovery learning model are the approach and model recommended in the 2013 Curriculum. Purpose of the research was to know effect of example non example method in scientific approach and discovery learning model on students' affective competence. It was a quasi-experimental research. It was done in junior high school 18 Padang to grade VII students. The instrument used was written test in form of multiple-choice and essay. Technique of data analysis used Mann Whitney U test. It was done by using SPSS software. The finding shows that example non example method in scientific approach and discovery learning model has significant effect on students' affective competence, with sig. value (0.036) < 0.05.
