Abstract. This study aims to (1) improve students' mathematical communication skills through the STAD Type Cooperative Learning Model with the Reciprocal Teaching Approach in MTs Islamiyah Medan, (2) describe the process of implementing the STAD Type Cooperative Learning Model with the Reciprocal Teaching Approach at MTs Islamiyah Medan. This research is a class action research with 31 students of VII-2 MTs Islamiyah Medan subject. Instruments used include learning implementation observation sheets, mathematical communication observation sheets, and mathematical communication test questions. Implementation of the STAD Cooperative Learning Model with the Reciprocal Teaching Approach includes: (1) Initial Activities: the teacher conveys apperception and motivation regarding the material to be studied; (2) this activity: group work which includes Clarifying discussion, Predicting discussion Questioning discussion, Summarizing discussion, discussion of LKS questions, and group percentage; (3) Closing: the teacher together with students draw conclusions on the material that has been learned. After learning takes place there is an increase in students' mathematical communication skills. This can be seen from the results of observations of the implementation of learning an increase in the percentage from cycle I to cycle II amounted to 90.90% to 94.45% with a very good category of accuracy. Furthermore, the results of observations of students' mathematical abilities also increased from cycle I by 75.00% (good category) to 82.41% (good category) in the second cycle. This is in line with the results of a mathematical communication test that has increased after the second cycle, which is as many as 27 students or 64.52% of the number of students in class VII-2 has increased in total scores to good categories.Keywords: Mathematical Communication, Cooperative, STAD, Reciprocal Teaching.

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.

Abstract-This research is supported by low interpersonal intelligence of learners on IPS learning in class VIII C SMP Negeri 45 Bandung. This can be seen from the still low empathy, prosocial, low self-awareness as a member of the group, social ethics of learners, problem-solving skills and effective communication skills of learners. Seeing the problem, the researcher chose Cooperative Learning Model Type Two Stay Two Stray (TSTS) as a solution to improve students' interpersonal intelligence. The purpose of this study is to describe the planning, implementation, obstacles and solutions and increase interpersonal intelligence. The type of research used is Class Action Research (PTK) Kemmis and Mc model. Taggart which consists of four stages. Stages of planning in this study include determining SK / KD and teaching materials, preparing RPP, Student Worksheet and create research instruments according to the needs of researchers. This research was conducted in three cycles and obtained the result of improvement of students' interpersonal intelligence in IPS learning. Increased interpersonal intelligence of learners is characterized by an increase that occurs in every aspect of the assessment of interpersonal intelligence. This proves cooperative learning model type two stay two stray (TSTS) can improve students' interpersonal intelligence.Keywords: Interpersonal Intelligence, Cooperative Learning Model type Two Stay Two Stray (TSTS).

This research was aimed at examining the improving mathematical connection and communication ability and self-concept of vocational students through cooperative learning of jigsaw so that they were able to be more motivated in learning mathematics, more understanding mathematics learning itself and to  apply it in everyday life. This research method was a quasi-pretest-posttest experiment that applied a jigsaw cooperative learning model. This study involved two groups of students who  studied about mathematical connection and communication skills and students' self-concepts. The instruments used were in the form of mathematical connection and communication skills, as well as student self-concept questionnaires. The research instruments were firstly tested for validity (logical and empirical), reliability, distinguishing features and the level of difficulty of the questions. The achievement of mathematical connections and communication skills and the self-concept of students who got learning with a scientific approach to the type of cooperative learning model jigsaw was better than students who only learned the scientific approach. In this study there was also an association between the ability of connections with mathematical communication of students in the high category. There was an association between the ability of connections with students' self-concepts in the high category. There was an association between mathematical communication skills and students' self-concepts in the high category.

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.
