Abstract

Tujuan: Penelitian ini bertujuan untuk meningkatkan hasil belajar matematika siswa kelas VII MTs Baitul Amal Pekanbaru pada semester ganjil tahun pelajaran 2025/2026 melalui penerapan model Problem Based Learning dengan konteks objek wisata lokal pada materi rasio. Metode: Penelitian ini merupakan Penelitian Tindakan Kelas (PTK) yang dilaksanakan dalam dua siklus dengan tahapan perencanaan, pelaksanaan tindakan, observasi, dan refleksi. Subjek penelitian adalah 18 siswa kelas VII MTs Baitul Amal Pekanbaru. Data dikumpulkan melalui lembar observasi aktivitas guru dan siswa serta tes hasil belajar, kemudian dianalisis secara deskriptif. Hasil: Hasil penelitian menunjukkan bahwa aktivitas guru meningkat dari 82% pada Siklus I menjadi 92% pada Siklus II, sedangkan aktivitas siswa meningkat dari 74% menjadi 88%. Hasil belajar matematika siswa juga mengalami peningkatan yang ditunjukkan oleh kenaikan persentase siswa yang mencapai Kriteria Ketercapaian Tujuan Pembelajaran (KKTP) dari 38,89% pada kondisi awal menjadi 50% pada Siklus I dan 66,67% pada Siklus II. Nilai rata-rata hasil belajar siswa meningkat dari 65,1 pada kondisi awal menjadi 71,6 pada Siklus I dan 77,6 pada Siklus II. Simpulan: Penerapan model Problem Based Learning dengan konteks objek wisata lokal dapat meningkatkan kualitas proses pembelajaran dan hasil belajar matematika siswa pada materi rasio. Model pembelajaran ini dapat dijadikan sebagai alternatif pembelajaran yang kontekstual untuk membantu siswa memahami konsep matematika secara lebih bermakna.

Abstract

This study aims to analyze students' errors in solving problem-solving problems on the material of two-variable linear equation systems based on Newman's theory. This study needs to be conducted in order to help find out what mistakes students make so that it will be easier to find solutions to minimize the occurrence of these errors in learning. The research method used is descriptive qualitative. The subjects in the study were 16 students of class X MA Cendekia Bangsa. The study was conducted in the 2024/2025 academic year, even semester. The data collection technique used by the researcher was using a test instrument in the form of two essay questions containing indicators of mathematical problem-solving abilities on the material of two-variable linear equation systems and interviews. The results of the analysis of students' errors in solving problem-solving problems on SPLDV material based on Newman's theory obtained 9.4 % reading errors (very low category); 28.1% understanding errors (low category); 40.6% transformation errors (sufficient category); 62.5% process skill errors (high category) and 21.9% answer writing errors (low category). The largest percentage of errors is in processing skills errors which are caused by many students still having problems with algebraic calculations and integer operations.

Abstract

This classroom action research aimed to improve the instructional process and enhance students' mathematical understanding ability through the application of the Realistic Mathematics Education (RME) approach in class XI TKJ 2 of SMK Negeri 1 Pekanbaru. A collaborative classroom action research design was used, conducted over two cycles, each consisting of planning, action, observation, and reflection. The study was carried out in the odd semester of the 2025/2026 academic year on the topics of composite functions, inverse functions, and function transformations. Data were collected through a mathematical understanding test in the form of essay questions and observation sheets documenting teacher and student activities throughout the learning process. The data were analyzed using descriptive and qualitative techniques. The results show that the implementation of the RME approach improved the learning process and increased students' mathematical understanding ability. The improvement in the learning process was indicated by the increasing quality of instruction in line with the stages of the RME approach, as reflected in the observations of teacher and student activities. In addition, the mathematical understanding test results demonstrated a gradual increase between before and after the intervention. This was evidenced by the rise in the number of students in the very high category from 2 to 12, accompanied by a decrease in those in the very low category from 19 to 4. Based on these findings, the RME approach is proven capable of improving the instructional process and enhancing the mathematical understanding ability of class XI TKJ 2 students at SMK Negeri 1 Pekanbaru in the odd semester of the 2025/2026 academic year on the topics of composite functions, inverse functions, and function transformations.

Abstract

Penelitian ini dilatarbelakangi oleh rendahnya kemampuan berpikir kritis siswa kelas XI TKJ 3 SMK Muhammadiyah 3 Pekanbaru. Hasil tes awal menunjukkan sebagian besar siswa belum mampu melakukan interpretasi, analisis, evaluasi, dan inferensi secara optimal. Kondisi ini disebabkan oleh pembelajaran yang masih berpusat pada guru, penggunaan soal rutin, serta kurangnya keterlibatan aktif siswa dalam proses pembelajaran. Penelitian ini bertujuan untuk memperbaiki proses pembelajaran dan meningkatkan kemampuan berpikir kritis melalui penerapan model Problem Based Learning (PBL). Metode penelitian yag digunakan adalah Penelitian Tindakan Kelas (PTK) kolaboratif yang dilaksanakan dalam dua siklus dengan subjek sebanyak 29 siswa. Instrumen penelitian meliputi lembar observasi aktivitas guru dan siswa serta tes kemampuan berpikir kritis. Data dianalisis secara kuantitatif berdasarkan hasil tes pada setiap indikator berpikir kritis. Hasil penelitian menunjukkan bahwa penerapan model PBL mampu meningkatkan aktivitas siswa dalam pembelajaran, serta berdiskusi, bekerja sama, dan mempresentasikan hasil. Selain itu, kemampuan berpikir kritis siswa mengalami peningkatan, ditandai dngan bertambahnya jumlah siswa pada kualifikasi baik dari 0 pada tes awal menjadi 10 orang pada siklus II, serta tidak adanya siswa pada kualifikasi kurang sekali.
