Abstract. The purpose of this study was to determine the effect of the trade a problem learning model by rewarding students' mathematical communication skills. This type of research is quasi-experimental research by determining one class of research samples taken randomly as the experimental class. In this study the method of data retrieval is carried out by applying to an experimental class a treatment condition. The population in this study were all VII grade students of SMP N 1 Gunung Malelala. The results show a strong relationship between the Trade A Problem learning model and reward for students' communication skills. Based on the results of the calculation of the regression equation the equation 𝑌̂=27,87+0,64𝑋 is obtained. In this equation the regression direction coefficient (b) = 0.64 is positive, which means that the two variables have a positive linear relationship.Keywords: trade a problem, mathematical communication skills.

The purpose of this study was to determine whether the mathematical communication skills and attitudes of students who were taught with the Think-Talk-Write (TTW) strategy were better than conventional learning. This research is a quasi-experimental research which compares two learning models, namely the TTW cooperative learning model and the conventional learning model. This research was conducted on students of class VII SMPS Mentari Bangsa Medan, which consisted of 2 classes. This study involved two variables, namely the independent variable and the dependent variable. The independent variable is the TTW and KAM learning strategy, while the dependent variable is the mathematical communication skills and attitudes of students towards learning. The sample consist of 42 students for TTW strategy and 37 students for conventional learning. The conclusion is that students who get learning with the TTW strategy have significantly better mathematical communication skills than students who get conventional learning (tcount = 4,93 more than ttable =1,66) and the attitudes of students who get learning with the TTW strategy are significantly better than students who get conventional learning (tcount = 3,14 more than ttable = 1,66).

This research is a quasi-experimental study which aims to describe the effect of cooperative learning type Think Pair Share (TPS) on students' mathematical communication skills, and to find out the percentage of students' activeness in participating in learning and knowing students' positive responses to learning. The output that will be generated in this study is that students can be more active in the learning process, more active in solving mathematical problems, and can be more confident in expressing their answers in public so that after applying cooperative learning models the Think Pair Share (TPS) mathematical communication skills of students will be better. The research subjects were divided into 2 groups, namely the experimental group taught using the cooperative learning model Think Pair Share (TPS) type, and the control group taught using Conventional learning models. Each group is taught with the same frequency of meetings with the same material. The results of the study show that the application of the cooperative learning model Think Pair Share (TPS) influences students' mathematical communication skills

This study aims to determine whether the Round Table cooperative learning model influences the mathematical communication skills of students of SMAN 101 Jakarta. This research was conducted in the even semester of the 2018/2019 academic year on the subject of Lines and Series. The research method used was quasi-experimental. The target population of this study were all students of SMAN 101 Jakarta and the affordable population in this study were students of XI MIPA. The sampling technique uses cluster random sampling technique. The research instrument used was a test of mathematical communication skills as many as four description questions. the instrument has gone through content validation tests, construct validation and empirical validation. After the instrument is valid, reliability is tested where the correlation coefficient obtained is 0.5602. After testing the normality, homogeneity and similarity of averages and cluster random sampling. XI MIPA 2 was chosen as the control class and XI MIPA 4 as the experimental class. Based on the calculation of the research data of the two classes, each of them is normally distributed and has the same or homogeneous variance. Therefore, hypothesis testing is done by using t-test statistics with a significant level α = 0.05. Based on the results of the test, the value of tcount = 2.43499 and t table = 1.6682 is obtained, so that it gets tcount> ttable. So reject H0. This shows that there is the influence of Round Table cooperative learning model on mathematical communication skills of students of SMAN 101 Jakarta.

Poor mathematical communication skills and motivation are influenced by several factors, such as the use of learning models used by teachers in learning. The use of appropriate learning models can improve students’ mathematical communication skills and motivation. This study aimed to determine the effect of the discussion learning model using Google Classroom and Google Form on students' mathematical communication in terms of students’ learning motivation. This type of research is quasi-experimental. Data were analyzed using two-way analysis of variance with unequal cells. Based on the results, it can be concluded that the discussion learning model using Google Classroom provided better communication skills than the learning model using Google Form, (2) there was no difference in the effect of learning motivation on students' mathematical communication, and (3) there was no interaction between learning model and learning motivation towards students' mathematical communication skills. Further research is needed to develop learning models using Google Classroom and Google Form by taking into account the characteristics of other students that are adjusted to the school curriculum.

Mathematical communication is very important in the process of learning mathematics. Through mathematical communication, students can organize their mathematical thinking in writing and communicate their understanding to others. However students mathematical communication skill are relatively low, so we need a learning model that can improve student’s mathematical communication skills by using brain based learning. The purpose of this research are  : (1) To determine the improvement of student’s mathematical communication skill after using Brain Based Learning Model. (2) To know the comparation between the student’s mathematical communication skill by using Brain Based Learning with convetional learning models. The research method used was a quasi-experimental design with pretest and posttest control group design. The result showed that : (1) The use of Brain Based Learning improves mathematical communication skill significantly. (2) Student’s mathematical communication skill by using Brain Based Learning were better that student’s mathematical communication skills by using conventional learning model.

Communication skills focus on the importance of speaking, writing, describing and explaining mathematical concepts. In achieving that success is by using cooperative learning model. This model is an effective teaching strategy in improving student achievement and socialization while contributed to their changing of attitudes and perceptions of the importance of learning and cooperation, including for their understanding of their peers from different ethnic backgrounds. This research was conducted at SD IT Faza Azkia Kelurahan Hutaraja, South Tapanuli Regency, North Sumatera Province. This research uses quasi experimental research method. This study aims to describe how to improve students 'mathematical communication skills before and after using cooperative learning model, and also to know the effectiveness of using cooperative learning model in improving students' mathematical communication ability. Based on the results of the study concluded there is an increase in the mathematical communication skills of students before and after using cooperative learning model. And the cooperative learning model is effective for teaching count number operations. This is shown by: the effectiveness of student learning activities, the ability of teachers in managing learning is effective, students 'responses to learning is positive and mastery of students' mathematical communication skills reach 100%.
