The subjects of this study were 36 eighth-grade students from class VIII2 at SMP Negeri 11 Pekanbaru. The research employed a Classroom Action Research (CAR) approach conducted in two cycles, with each cycle consisting of four stages: planning, implementation, observation, and reflection. The instruments used in this study included instructional tools and a mathematical problem-solving ability test (KPMM). The instructional tools consisted of teaching modules, student worksheets (LKS), and formative tests. Data were collected through the KPMM tests and observation sheets documenting the activities of both students and the teacher. Data analysis was carried out using descriptive narrative and statistical techniques. The results of the study indicated that the implementation of the Power of Two method was effective in improving the quality of the learning process and enhancing students' mathematical problem-solving skills. In the first cycle, 2 students achieved scores in the "very good" category, 5 in the "good" category, and 4 in the "fair" category. In the second cycle, there was a significant improvement: 26 students achieved "very good" scores, 10 were in the "good" category, and none were categorized as "fair." This indicates that by the second cycle, students had become accustomed to using the cooperative learning model with the Power of Two method in solving mathematical problems. In conclusion, the implementation of the cooperative learning model using the Power of Two method has been proven to improve the learning process and enhance the mathematical problem-solving abilities of Phase D students in class VIII2 at SMP Negeri 11 Pekanbaru during the odd semester of the 2024/2025 academic year

Profil Koneksi Matematis Siswa SMP Negeri 4 Sigi Kelas IX Pada Materi Bangun Ruang Ditinjau dari Kemampuan Matematika
No full textThis qualitative descriptive research aims to describe the mathematical connections of 9th-grade students at SMP Negeri 4 Sigi regarding spatial shapes based on their mathematical ability levels. Data were collected through written tests and interviews to explore students' understanding in depth. The results indicate that students with high mathematical ability are capable of connecting surface area with the area of a rectangle, converting diameter to radius in volume calculations, and systematically linking the concepts of area and volume. They can effectively apply mathematics to other disciplines and real-life contexts. Students with moderate ability demonstrate similar skills in connecting surface area, volume, and daily applications, yet they tend to be less specific in identifying interdisciplinary connections, such as with economics. Meanwhile, students with low ability are able to determine surface area and provide real-life examples, but they encounter difficulties in relating surface area to the concept of a rectangle's area and are unable to identify interdisciplinary relationships in written tests. Overall, there are significant differences in the depth of mathematical connections and systematic procedural abilities among the three groups of students in solving spatial shape problems
