In learning students convey the results of their work is not always easy to accept. This is because their level of mathematical communication is not high. To improve their communication skills, a learning model that emphasizes communication aspects is needed, one of these models is two stay two stray. For this reason, through this study to improve students' mathematical communication skills, the two stay two stray learning model was applied to the limit material of trigonometric functions. This research was conducted on students of class XII-2 of Madani Integrated Model Senior High School in the 2022/2023 school year. This research is a collaborative classroom action research (PTK) which is carried out in 2 learning cycles. The results of the research in cycle 1 get the level of mathematical communication skills of student A is at level 1, student B is at level 2, student C is at level 3. Then revisions were made in cycle 2 learning to get the results of student A at level 2, student B at level 3 and student C at Level 3. From these results it can be concluded that learning mathematics by applying the two stay two stray type cooperative learning model can improve mathematical communication skills for students who have low and medium abilities.Keywords : Two stay two stray, Mathematical Communication

Student learning motivation will increase, which is determined by the teacher's ability to learn design. As a result, students are more interested in actively searching and finding their ideas. This study aims to determine increased student activity and motivation to learn mathematics on Limited trigonometric function. Researchers used the Window-Shopping learning model assisted by Padlet. This research is a collaborative Classroom Action Research. The subjects in this study are students of class XII-1 at Madani Integrated Model Senior High School in the 2023/2024 academic year. The stages in the research follow the flow of Kemmis and McTaggart and consist of planning, action, observation, and reflection. Data collection in this study was conducted by observing student activity during the teaching and learning process and using questionnaires. The results showed that students' learning activities are significantly increased. This happens more when they are involved in the learning process; consequently, students can build their knowledge. Students support each other, share ideas, and collaborate in constructing their knowledge. In addition, the results of this study are based on the completion of a student learning motivation questionnaire. Based on the questionnaire obtained in the first cycle, it amounted to 70.67%. In the second cycle, it increased by 11.35%. So, the total increase is 82.02%. This can be categorized in the predicate "good."

Mathematical communication skills are one of the skills that must be improved in students because before solving a problem and doing reasoning, students need to have mathematical communication skills first, namely the ability to convey mathematical ideas, both verbally and in writing and the ability to understand and accept other people's mathematical ideas, as well as the ability to use symbols, notations, and structures in a mathematical concept. The purpose of this study was to obtain an overview of the improvement of students' mathematical communication skills through collaborative classroom action research methods. As for improving mathematical communication skills in class XI-2 students at SMA Negeri Model Terpadu Madani, the researcher utilized media in the form of presentation boards given to students in groups to train their ability to express ideas and present them to other students in front of the class. Based on the results of the study, the mathematical communication skills of students in the class continued to increase in each cycle given for 6 meetings.

Tulisan ini merupakan best practice yang dilakukan di SMA Model Madani Palu. Sebelumnya alur pembelajaran yang dilakukan yaitu mengerjakan tugas dibuku, menuliskan di papan tulis dan dan mempresentasikan dengan membacakan hasilnya. Kemudian ditemukan media papan presentasi yang sederhana dan inovatif. Selain itu biaya untuk membuat papan presentasi relative murah. Media ini dapat dipergunakan berulang-ulang karena ditulis dengan spidol dan dapat dihapus. Metode yang dilakukan, siswa menuliskan pekerjaannya pada papan presentasi. Penggunaan media ini dapat menggali komunikasi matematis siswa, karena siswa terlatih menyampaikan dan menuliskan langsung hasil yang diperoleh. Hal ini diperkuat berdasarkan hasil pengisian angket bahwa penggunaan papan presentasi (1) dapat memotivasi siswa sehingga terlibat dalam menjawab soal atau selama kegiatan pembelajaran di kelas, (2) memberanikan diri tampil kerja/tugas yang diberikan di kelas, (3) merasa tertantang untuk mengerjakan tugas matematika yang diberikan karena kolaborasi (4) Menyelesaikan tugas-tugas dalam pembelajaran ini membuat siswa merasa puas terhadap hasil yang mereka capai, (5) Siswa terlibat aktif dalam kelompok, (6) berani menyampaikan ide gagasan secara tertulis dan lisan dan(7) melakukan suatu hal lebih detailsi. This study aims to investigate the best practice of mathematical communication carried out at SMA Model Madani Palu. In mathematical communication, the learning flow was conducted by doing assignments in books, writing on the board, and presenting the results through reading. Then, a media in the form of presentation board which is simple and innovative was found. In addition, the cost of making a presentation board is relatively cheap. This media can be used repeatedly because it is written with erasable markers. The method used, students write their work on the presentation board The use of this media is expected to be able to explore students' mathematical communication as they are trained to convey and write down the results obtained directly on it. This statement is reinforced by the results of the questionnaire that was disseminated in this study. From this study, it was found that the use of a presentation board (1) can motivate students to be involved in answering questions or during learning activities in class, (2) make students to be braver to perform work/assignments given in class, (3) challenge students to work on the given collaborative mathematical assignments, (4) make students feel satisfied by completing the assignments, (5) involve students in a group, (6) make students dare to convey ideas in writing or orally, and (7) encourage students to do something more detailed.
