Mathematical communication skills of students are still relatively low. One learning model can improve students 'mathematical communication skills and at the same time students' mathematical disposition is the Problem Based Learning (PBL) model. The aim to be achieved is to find out the improvement of students 'mathematical communication skills and mathematical disposition using PBL models in terms of students' initial mathematical level. This research is an experimental research design with pretest posttest control group design. The research population was Grade VII students of SMP 9 Langsa. Students are grouped into two classes namely the experimental class and the control class randomly selected from eight parallel classes. The instrument used was a test of mathematical communication skills and a mathematical disposition questionnaire. Data analysis was performed using two-way ANOVA. The results showed that improving students 'mathematical communication ability and students' mathematical disposition by applying PBL learning models is better than students applying conventional learning models. There is no interaction between the PBL learning model with student level on mathematical communication skills and students' mathematical disposition. Abstrak Kemampuan komunikasi matematis siswa masih tergolong rendah. Salah satu model pembelajaran dapat meningkatkan kemampuan komunikasi matematis siswa dan sekaligus disposisi matematis siswa adalah model Problem Based Learning (PBL). Tujuan yang ingin dicapai ialah untuk mengetahui peningkatan kemampuan komunikasi matematis siswa dan disposisi matematis menggunakan model PBL ditinjau dari kemampuan awal matematis siswa. Penelitian ini merupakan penelitian eksperimen dengan desain pretest postest control group design. Populasi penelitian adalah siswa kelas VII SMP Negeri 9 Langsa. Siswa dikelompokkan menjadi dua kelas yaitu kelas eksperimen dan kelas kontrol yang dipilih secara acak dari delapan kelas paralel. Instrumen yang digunakan tes kemampuan komunikasi matematis dan angket disposisi matematis. Analisis data dilakukan dengan menggunakan anova dua arah. Hasil penelitian menunjukkan bahwa peningkatan kemampuan komunikasi matematis siswa dan disposisi matematis siswa dengan menerapkan model pembelajaran PBL lebih baik dari pada siswa yang menerapkan model pembelajaran konvensional.

Students' mathematical communication is stated to be low because students learn by listening and seeing the teacher solve mathematical problems and students have difficulty in expressing everyday events in mathematical models. This study aims to determine whether there is an influence of the Inside Outside Circle (IOC) type of cooperative learning model on students' mathematical communication skills better than using scientific learning. This study uses a quantitative approach with the type of research Quasi-Experimental Design and the design of this research The Nonequivalent Postets-Only Control Group Design. The population in this study were all students of class VIII SMP Negeri 1 Nisam, while the samples were class VIIIB as the experimental class and class VIII-A as the control class with the sampling technique of purposive sampling. The data collection technique in this study used a mathematical communication ability test. The data analysis was carried out for the mathematical communication ability test using the t-test because the data were normally distributed and homogeneous, the data were processed using SPSS 18 software and the hypothesis test results were obtained with a significant value of 0.000 less than 0.05, which means reject H0 and accept Ha. The results showed that there was an effect of the Inside-Outside Circle (IOC) type of cooperative learning model on students' mathematical communication skills.

One of the objectives of mathematics learning is to learn to communicate, because through communication students can communicate ideas, reasoning, and be able to compile mathematical evidence using complete sentences, symbols, tables, diagrams, or other media. One learning model that can be applied to improve students' mathematical communication skills is a group investigation model. This study aims to determine the improvement of students' mathematical communication skills between students who obtain group investigative learning and students who obtain conventional learning are reviewed as a whole and based on the level of students. This study uses experimental research. The design of this study was a pre-test post-test control group design. The population in this study were all seventh grade students of SMP Negeri 9 Banda Aceh. Samples are taken through random sampling techniques. To obtain research data, the instrument is used in the form of tests of students' mathematical communication skills. The results of the study showed that the mathematical communication skills of students who received group investigation learning were better than students who obtained conventional learning both overall and based on the level of students.

Abstract. This research is based on the students' mathematical communication ability at SMP Negeri 1 Pasir Penyu which is still low. To overcome the problem is applied learning model Auditory Intellectually Repetition (AIR). This study aims to determine the ability of students' mathematical communication using the learning model of Auditory Intellectually Repetition (AIR). This research type is quasi experiment research. The research design used was randomized subjects posttest only control group design. The sampling technique used is cluster random sampling. After the sample was taken randomly, the students selected VIII.6 class as experimental class and students of class VIII.5 as the control class. The instrument in this research is a test of students' mathematical communication skill. The data analysis technique used Independent Samples T-Test (t-test) test. Based on hypothesis test results obtained that tcount = 5,065> ttable = 2.002 with (df = 60) and a real level of 5%. Reject H0 if thitung value is ttable. So it can be concluded that the mathematical communication skills of students using the learning model of Auditory Intellectually Repetition (AIR) is better than the students' mathematical communication skills using conventional learning model. Keywords: Auditory Intellectually Repetition (AIR), mathematical communication.

The purpose of writing this paper is to study the enhancement of mathematical communication skills of students who have gained the implementation of Somatic, Auditory, Visual, and Intellectual (SAVI) approaches better than those who have learned scientific approaches. The approach used is a quantitative approach with the type of quasi-experimental design with a nonequivalent control group design. The population in this study are all grade X students of SMK Negeri 1 Nisam with a sample of TBSM II class students as an experimental class and TKJ I as a control class taken to use the purposive sampling technique. The data collection techniques used in this research are mathematical communication skills tests of students and observation sheets. Data analysis was done using test-t, that because the data of the n-gain score obtained with normal distribution, but has a variance that is not homogeneous. The significant result of the statistics equal variances not assumed is 0.00 smaller than 0.05 H0 is rejected. The result showed that the enhancement of mathematical communication skills of students who gained the implementation of somatic, auditory, visual, and intellectual (SAVI) were better than students who gained scientific learning approaches.
