The aim of this study is to enhance the students' ability to solve math problems and classical completeness of students in grade VIII SMP Negeri 10 Medan through Guided Discovery Learning model. This research is called Classroom Action Research (CAR) and carried out by two cycles, where each cycle includes the stages of planning, implementation, monitoring, evaluation and reflection. The research subjects were 32 students of grade VIII-C SMP Negeri 10 Medan T.A 2023/2024. The object of this study is to enhance the math problem solving capability of students by applying the Guided Discovery Learning model on chance material. The results obtained from the initial ability test before applying the learning model that the average student score was 40.19. In cycle I, there was an increase with the average student score of 66.21 which was in the moderate category and there were 16 students (50%). Then in cycle II it increased with an average student score of 85.29 which is in high category and 29 students (90.62%). Thus the conclusions that can be drawn from this is the Guided Discovery Learning model can enhance the ability of students in grade VIII SMP Negeri 10 Medan to solve problems of math

This research was conducted because there were still relatively low mathematics learning outcomes of students, students were less enthusiastic about conventional learning methods and they did not understand the concepts in learning mathematics. Therefore, innovation is needed in learning methods that can improve students' understanding of concepts and interest in learning. One model that is considered effective is the TGT model which can facilitate a more interesting and enjoyable learning experience. This community service is to determine the increase in student learning outcomes after the TGT Cooperative Learning Model was implemented. In addition, to determine the classical completeness of student learning outcomes after being taught using the learning model. Community service was held at MTS Islamiyah Belawan in the even semester of 2023/2024. Classroom action research is a type of research that is carried out in five stages: class presentation, group learning, games, tournaments and team awards. The instruments used are tests and observations. The results of the research are that by using the TGT cooperative learning model, the average value of student learning outcomes increased to 68.16 in the first cycle and 84.5 in the second cycle. In cycle I, classical learning completion increased from 53.34% to 86.67% when the TGT learning model was applied. Of the 30 students who took the test, 26 (86.67%) of them met the completion criteria, namely achieving a score greater than or equal to 75, while 4 (13.33%) did not meet the completion requirements. During cycle II, the average point score for observing learning implementation activities in the classroom was 91.27 with the best group. So it is concluded that students have better learning outcomes with the TGT learning model. Furthermore, the completion of their learning outcomes is classified as complete.

Penelitian ini bertujuan untuk mengetahui perbedaan kemampuan penalaran matematis siswa melalui pembelajaran Problem Based Learning (PBL) dibandingkan dengan pembelajaran biasa pada siswa kelas VII SMP Negeri 3 Tebing Tinggi. Penelitian dilakukan dengan menggunakan tes kemampuan penalaran matematis pada kelas eksperimen (PBL) dan kelas kontrol (pembelajaran biasa). Hasil uji hipotesis menggunakan uji-t menunjukkan bahwa thitung > ttabel yaitu 2,014 > 2,010, sehingga Ho ditolak dan Ha diterima. Hal ini menunjukkan bahwa kemampuan penalaran matematis siswa yang diajar dengan model PBL lebih baik daripada yang diajar dengan pembelajaran biasa. Data pretest dan posttest menunjukkan adanya peningkatan kemampuan pada semua indikator penalaran matematis baik di kelas eksperimen maupun kelas kontrol, namun kelas eksperimen menunjukkan hasil yang lebih baik pada sebagian besar indikator. Pada indikator mengajukan dugaan, kelas kontrol lebih baik dengan persentase 76% dibandingkan kelas eksperimen 48%. Pada indikator melakukan manipulasi matematika, memeriksa kesahihan argumen, dan menarik kesimpulan, kelas eksperimen lebih unggul masing-masing dengan persentase 36%, 8%, dan 80%, sedangkan kelas kontrol hanya 12%, 4%, dan 60%. Dengan demikian, pembelajaran PBL efektif meningkatkan kemampuan penalaran matematis siswa.

This research aims to: (1) determine the validity, practicality, and effectiveness of Android media based on the realistic approach that was developed, (2) determine the increase in students' mathematical problem-solving skills using Android media based on the realistic approach that was developed. This research is development research. The development model used is the Plomp & Nieveen Development model which consists of three phases, namely the preliminary phase, the development or prototyping phase, and the assessment phase. Based on the results of trial I and trial II, it was found that: 1) Android media based on a realistic approach to improving students' mathematical problem-solving skills were developed which met the criteria of being valid, practical and effective; 2) Increasing problem-solving skill using Android media based on a realistic blended learning approach that has been developed as seen from the N-gain value in trial I of 0.55, increasing to 0.60 in trial II, meaning it is in the "medium" category.
