Pembelajaran matematika merupakan proses interaksi atau komunikasi antara guru dan peserta didik serta lingkungan belajar agar peserta didik memperoleh kompetensi dalam bidang matematika. Kompetensi di bidang matematika yang harus dimiliki oleh peserta didik salah satunya adalah kemampuan pemecahan masalah matematis dan kemampuan komunikasi matematis, karena pada dasarnya kemampuan tersebut merupakan suatu kemampuan yang penting dan perlu dikuasai oleh peserta didik yang belajar matematika. Khususnya peserta didik sekolah menengah (SM). Metode yang digunanakan dalam penelitian ini adalah mix method research, (metode campuran) dengan jenis sequential explanatory. Desain penelitian kuantitatif menggunakan true experimental. Sedangkan desain penelitian kualitatif menggunakan deskriptif-kualitatif yang digunakan untuk melengkapi penelitian kuantitatif. Pada artikel ini dijelaskan bahwa perlakuan dengan model kooperatif tipe STAD dapat mempengaruhi kemampuan pemecahan masalah matematis dan kemampuan komunikasi matematis peserta didik. Hal tersebut dapat dilihat dalam hasil analisis data kuantitatif maupun kualitatif yang menunjukkan adanya perbedaan kemampuan pemecahan masalah matematis dan kemampuan komunikasi matematis antara peserta didik kelas eksperimen yang diberi perlakuan dengan model kooperatif tipe STAD dengan peserta didik kelas kontrol yang diberi perlakuan dengan model konvensional. Mathematical learning is a process of interaction or communication between teachers and students and the learning environment so that students gain competence in the field of mathematics. One of the competencies in the field of mathematics that must be possessed by students is mathematical problem solving skills and mathematical communication skills, because basically these abilities are an ability that is important and needs to be mastered by students who learn mathematics. Especially middle school students. The method used in this research is a mix method with sequential explanatory methods. Quantitative research design uses true experimental. While the qualitative research design uses descriptive-qualitative research that is used to complement quantitative research. In this article, it is explained that the treatment with the cooperative type STAD model can affect students' mathematical problem solving abilities and mathematical communication skills. This can be seen in the results of quantitative and qualitative data analysis which shows a difference in mathematical problem solving abilities and mathematical communication skills between experimental class students who were treated with the cooperative type STAD model and control class students who were treated with conventional models.

The main purpose of this study was to compare and examine the effectiveness of problem-posing and think-pair-share cooperatives' learning models on mathematical problem-solving skills and mathematical communication skills. This study was experimental research with a quasi-experimental design. The samples of the study were 41 students for classroom experiments and 40 students for classroom control. The instruments employed in this study were pre-test and post-test. The instruments were made in essay forms which design to measure students’ mathematical problem-solving skills. The result of the study showed that problem-posing and think-pair-share are very effective to improve students’ mathematical achievements. However, between the problem-posing and think-pair-share, the think-pair-share is more effective than problem-posing, view from the standards of mathematical problem-solving skills and mathematical communication skills of Junior High School students.

Initial Knowledge

Mathematical problem solving is a problem solving that uses mathematical problem solving. Students in the problem solving did not use the polya method so that students succeeded in difficulties. Educators still use conventional learning models so that students become bored, passive and reluctant to ask whether going forward working on the questions given by the educator, so that new learning models need to be applied. The e-learning learning model assisted with Edmodo learning media is an online presentation material on an Edmodo account using the mobile phone of students. PAM is the knowledge learned by students before getting learning material. This study aims to study the interaction of e-learning learning models assisted by Edmodo learning media to solve mathematical problems. This study is quantitative research. Data collection used with tests, interviews, collection and collection. The data analysis technique uses two-way anava test with cells that are not the same. From the results of the analysis, the influence of the e-learning learning model on mathematical problem solving abilities. It is necessary to question the high, medium, and low mathematical initial knowledge of Great mathematical problem solving ability, then there is no difference between assisted e-learning learning models edmodo, mathematical initial knowledge of mathematical problem solving abilities.

The emphasis of mathematics learning, especially students' communication skills, needs to be considered from gender equality in solving mathematical problems. This study aims to describe: 1) the potential mathematical communication skills of students based on gender; 2) gender equality in communicating mathematical problem solving; and 3) the suitability of the form of the model or the applied form to develop students' mathematical communication skills based on gender at school. This research is a descriptive qualitative research conducted on all junior high school students in Langsa with a purposive sampling technique of 283 students. The data were collected through mathematical communication skills and questionnaire tests which were analyzed descriptively using the concept of Miles and Huberman. The results showed that: 1) mathematical communication skills of female students were better than male students in solving mathematical problems; 2) mathematical communication skills of male students are better in suburban schools and female students are better in downtown schools; and 3) learning implementation plans are still limited in emphasizing mathematical communication skills and learning tends to be cooperative and individual. It is recommended that learning plans refer to developing mathematical communication skills that pay attention to students' gender equality in order to optimize mathematical problem solving.
