Mathematical communication skills are one of the competencies that students must have in the 21st century.  This study aims to anylize and describe students’ mathematical communication skills in terms of self efficacy on the polyhedrons material. The research used descriptive qualitative methods. The subjects were 9 grade students of An nashichah private junior high school selected purposively.  Data was collected through online test, questionnaires and interviews using WhatsApp. The data analyzed through 3 stages, namely data reduction, data presentation and conclusions. The results showed that the students’ mathematical communication skills were low. When viewed from students’ self efficacy, high self efficacy students have high mathematical communication. Meanwhile, low and moderate self efficacy students have low mathematical communication skills. The use of Whatsapp media is not able to support students mathematical communication skill and self efficacy. The tachers need to design learning media to help students improve their mathematical communication skills and self efiicacy.

This study was aimed to describe the mathematical communication skill of eighth-grade students of SMP IT Insan Mulia of Batanghari based on gender in solving questions about circle material. The subjects of this study consisted of 21 male and 21 female students. The research method used is descriptive qualitative. The data collection instrument used in this study is the mathematical communication skill test. The mathematical communication skill test instrument consists of three questions in the form of an essay. The results showed that in general, the mathematical communication skills of male and female students are in a low category. The low ability of students' mathematical communication is due to a weak understanding of concepts, not understanding the usefulness of mathematical symbols, and students' unfamiliarity in working on problems. Male and female students have different mathematical communication skills. Female students have better communication skills than male students in conveying ideas to provide an explanation on each indicator of the mathematical communication skills test.

Brain Based Learning

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.

The instrument used in this study is the learning achievement test, a test of mathematical communication skills, and interpersonal skills student questionnaires. To test the effectiveness of setting Think Pair Share (TPS) in the approach to discovery learning and problem-based learning, the one sample t-test was carried out. Then, to investigate the difference in effectiveness between the setting Think Pair Share (TPS) in the approach to discovery learning and problem-based learning, the Multivariate Analysis of Variance (MANOVA) was carried out. The research findings indicate that the setting TPS discovery approach to learning and problem-based approach to learning (PBL) is effective in terms of learning achievement, mathematical communication skills, and interpersonal skills of the students. No difference in effectiveness between setting TPS discovery approach to learning and problem-based learning (PBL) in terms of learning achievement, mathematical communication skills, and interpersonal skills of the students.Keywords: TPS setting in discovery learning approach, in problem-based learning, academic achievement, mathematical communication skills, and interpersonal skills of the student
