Abstract

This research aims to describe the ability to solve mathematical problems in terms of the level of mathematical communication skills of class IX students at SMPN 1 Batulayar for the 2023/2024 academic year. The type of research used is descriptive qualitative. Based on the results of data analysis, students with high mathematical communication skills were able to fulfill several indicators of problem-solving ability, such as the second and third indicators correctly, although there were students who were able to fulfill the first indicator on several questions. For mathematical communication skills, students in the moderate category are able to fulfill several problem-solving indicators, such as the second and third indicators, although they are not yet complete, but are not yet able to fulfill the first and fourth indicators. Meanwhile, students with low mathematical communication skills have not been able to fulfill the four indicators of mathematical problem-solving abilities.

Abstract

Pembelajaran matematika masih dianggap sulit dan kurang menarik bagi siswa karena cenderung monoton dan abstrak. Salah satu solusi yang dapat diterapkan adalah pembelajaran kooperatif yang melibatkan siswa secara aktif. Penelitian ini bertujuan untuk meningkatkan hasil belajar matematika pada materi persamaan dan fungsi kuadrat melalui penerapan model pembelajaran kooperatif tipe Team Game Tournament (TGT) berbantuan media ular tangga. Penelitian ini merupakan penelitian tindakan kelas (PTK) yang dilaksanakan dalam tiga siklus, masing-masing terdiri dari tahap perencanaan, pelaksanaan, observasi, evaluasi, dan refleksi. Instrumen penelitian meliputi lembar observasi aktivitas siswa, aktivitas guru, dan hasil belajar siswa. Hasil penelitian menunjukkan peningkatan skor rata-rata aktivitas siswa dari kategori kurang aktif pada siklus ke-1, menjadi aktif pada siklus ke-2, dan sangat aktif pada siklus ke-3. Dari segi hasil belajar, rata-rata hasil belajar siswa meningkat dari 75,70 dengan ketuntasan klasikal 69,56% pada siklus ke-1, menjadi 83,04 dengan ketuntasan klasikal 82,60% pada siklus ke-2, dan mencapai 86,95 dengan ketuntasan klasikal 91,30% pada siklus ke-3. Kesimpulannya, penerapan model pembelajaran kooperatif tipe TGT berbantuan media ular tangga dapat meningkatkan aktivitas dan hasil belajar matematika siswa kelas XI di SMKN 1 Gerung.

This research is descriptive qualitative research. The research subjects consisted of 6 students who were taken using a purposive sampling technique. As for the data collection techniques, this research is using three methods, which are questionnaires, tests, and interviews. The data analysis technique uses Miles and Huberman consisting of data reduction, data display, and conclusions are drawn. The results show that subjects with high self-confidence and moderate self-confidence are able to carry out the stages of understanding the problem, the stages of devising a plan, the stages of carrying out the plan, and the stages of looking back. Meanwhile, subjects with low self-confidence are only able to carry out the stages of understanding the problem.
