This study aimed to determine the improvement of students' mathematical communication skills in relation and function materials through the Reciprocal Teaching learning model in class VIII of SMPS National Development Pangkalan Susu. The researchers used classroom action research (CAR) which is carried out in 2 cycles, each cycle was carried out in 2 meetings. The subjects in this study were students of class VIII of SMPS National Development Pangkalan Susu, totaling 22 people. Data collection techniques used were teacher and student observation sheets, and tests of mathematical communication skills. The test was carried out 3 times, namely a diagnostic test, a test for mathematical communication skills I, and a test for mathematical communication skills II. The results of the research at the time of the diagnostic test showed that the students' mathematical communication skills in explaining/writing the elements were known, the elements were asked and concluded correctly and completely (33.4%), painting pictures, diagrams, graphs, or tables completely and correctly (38%), and express mathematical ideas using symbols or mathematical language in writing as a complete and correct representation of an idea or ideas (32%). After being given action in Cycle I and Cycle II, the students were able to explain/write known elements, ask questions and conclusions correctly and completely, describe pictures, diagrams, graphs, or tables completely and correctly, and state mathematical ideas using symbols or mathematical language in writing as a complete and correct representation of an idea or idea. The results of the mathematical communication ability test given in the classical cycle I obtained that students who completed were 10 students (45.45%) out of 22 students with an average of 58.09, in the second cycle who completed increased to 16 students from 22 students (81 ,81%) with an average of 74.18 and has achieved the classical completeness criteria because 80% of the number of students have mathematical communication skills in the sufficient category, namely 70. Based on the results of the study, it can be concluded that the Reciprocal Teaching model can improve students' mathematical communication skills in SMPS National Development of Pangkalan Susu.

Terdapat beberapa kemampuan yang seharusnya dimiliki peserta didik untuk menghadapai kemajuan jaman pada saat ini, diantaranya adalah kemampuan komunikasi dan penalaran. Matematika sebagai salah satu mata pelajaran yang telah dipelajari sejak taman kana-kanak sampai perguruan tinggi memainkan peran yang penting untuk mengembangkan kemampuan tersebut. Komunikasi dan penalaran matematika merupakan dua hal yang tidak dapat dipisahkan dalam pembelajaran matematika. Diharapkan kedepannya dengan semakin membaiknya pembelajaran yang dilakukan guru sebagai pendidik, kedua kemampuan tersebut dapat meningkat. Hal ini diharapkan agar peserta didik dapat bersaing dengan bangsa lainnya. Kata Kunci: Komunikasi matematika, Penalaran Matematika

Penelitian ini bertujuan untuk mengetahui apakah melalui penerapan model pembelajaran kooperatif tipe Think Pair Share (TPS) dapat meningkatkan kemampuan pemecahan masalah matematika siswa pada materi sistem persamaan linear dua variabel (SPLDV) pada kelas VIII-3 SMP Negeri 13 Binjai. Jenis penelitian ini adalah Penelitian Tindakan Kelas (PTK). Subjek dalam penelitian ini adalah 30 siswa dan objek penelitian ini adalah kemampuan pemecahan masalah matematika siswa pada materi sistem persamaan linear dua variabel. Penelitian ini merupakan penelitian tindakan kelas (PTK) yang terdiri atas 2 siklus, masing-masing terdiri dari 2 kali pertemuan. Sebelum memberikan tindakan, terlebih dahulu diberikan tes awal dan setiap akhir siklus diberikan tes kemampuan pemecahan masalah. Dari hasil analisis data tes awal diperoleh banyaknya siswa yang mencapai ketuntasan belajar dari tes awal yaitu 1 dari 30 siswa atau 3,33% dengan rata-rata kelas 40.83. Hasil analisis data pada siklus I setelah menerapkan model pembelajaran kooperatif tipe Think Pair Share (TPS) menunjukkan banyaknya siswa yang mencapai ketuntasan belajar adalah 20 dari 30 siswa atau 66,6% dengan rata-rata kelas 76,34. Hasil analisis data akhir siklus II dengan pembelajaran yang sama diperoleh banyaknya siswa mencapai ketuntasan belajar yaitu 26 dari 30 siswa atau 86,7% dengan rata-rata kelas 85,19 Ini berarti terjadi peningkatan kemampuan pemecahan masalah siswa dari siklus I hingga siklus II. Berdasarkan kriteria ketuntasan klasikal maka pembelajaran ini telah mencapai target ketuntasan klasikal. Dengan demikian dapat disimpulkan bahwa penerapan model pembelajaran kooperatif tipe Think Pair Share dapat meningkatkan kemampuan pemecahan masalah matematika siswa. ABSTRACTThis study aims to determine whether the application of the Think Pair Share (TPS) cooperative learning model can improve students' mathematical problem solving skills in the material of a two-variable linear equation system (SPLDV) in class VIII-3 SMP Negeri 13 Binjai. This type of research is Classroom Action Research (CAR). The subjects in this study were 30 students and the object of this research was the students' mathematical problem solving ability on the material of a two-variable linear equation system. This research is a classroom action research (CAR) which consists of 2 cycles, each consisting of 2 meetings. Before giving the action, first a preliminary test is given and at the end of each cycle a problem-solving ability test is given. From the results of the initial test data analysis, it was found that the number of students who achieved learning completeness from the initial test was 1 out of 30 students or 3.33% with a class average of 40.83. The results of data analysis in the first cycle after applying the Think Pair Share (TPS) cooperative learning model showed that the number of students who achieved complete learning was 20 out of 30 students or 66.6% with a class average of 76.34. The results of data analysis at the end of the second cycle with the same learning obtained the number of students who achieved mastery learning, namely 26 of 30 students or 86.7% with a class average of 85.19 This means that there is an increase in student problem solving abilities from cycle I to cycle II. Based on the criteria of classical completeness, this learning has reached the target of classical completeness. Thus, it can be concluded that the application of the Think Pair Share cooperative learning model can improve students' mathematical problem solving abilities

The methods used in this research is literature study of 6 sources consists of 3 thesis and 3 journals discuss the use of learning media in the Problem Based Learning model in Indonesia published in the span of 2016-2022. From the calculation of the effect size, the average value is 0.79 which is categorized in the medium category. This shows that the use of learning media with Problem Based Learning in mathematics learning had a positive effect on improving the mathematical ability of students and the effect obtained is in the medium category. The mathematical ability could be improved based on the literature study such as student’s mathematical connection ability, student’s mathematical problem soving ability dan student’s mathematical numeracy literacy ability. The type of learning media according this research are animation, geogebra, microsoft power point, fun math book, cabri 3D v2 dan youtube. Hope for further research can be analyzed more deeply by using more sources so the result will be more maximal and varied.
