Abstract

Tujuan dari penelitian ini adalah untuk menjelaskan rencana pembelajaran, pelaksanaan, dan peningkatan pemahaman konsep siswa pada pelajaran matematika di kelas III SDN 1 Margoyoso. Dengan menggunakan model Contextual Teaching and Learning (CTL), penelitian ini bertujuan untuk menyelesaikan masalah ini. Penelitian ini melibatkan 18 siswa. Penelitian Tindakan Kelas (PTK) adalah pendekatan yang digunakan. PTK terdiri dari langkah-langkah perencanaan, pelaksanaan, observasi, dan refleksi. Data dikumpulkan melalui observasi, catatan lapangan, dan tes. Lembar observasi, catatan lapangan, dan lembar kerja siswa digunakan untuk menganalisis pendekatan kualitatif dan kuantitatif. Hasil penelitian menunjukkan bahwa penerapan metode CTL berhasil meningkatkan pemahaman konsep matematika siswa. Pada siklus I ketuntasan klasikal mencapai 66% dengan nilai rata-rata 73,61%. Sedangkan pada siklus II ketuntasan meningkat menjadi 83% dengan nilai rata-rata 80,56% yang menunjukkan kriteria sangat baik. Dengan demikian, model pembelajaran CTL terbukti efektif meningkatkan pemahaman konsep matematika siswa kelas III.

Abstract

The purpose of this study is to describe students’ activities during realistic mathematics learning using the context of trailer truck wheels and marble games in addition and subtraction material. This research employed a design research method with 23 first-grade students of SD Negeri 3 Krasak, Jepara Regency, Central Java as participants. The findings indicate that the use of trailer truck wheels as concrete media increased students’ activeness and curiosity in understanding the concept of addition. Students were able to redraw the wheels, perform calculations, and match their drawings with real objects, leading to an understanding of addition as a process of combining. Meanwhile, through the marble game, students engaged in learning while playing and understood subtraction as the process of taking away from a whole. Overall, students actively participated and successfully completed the activities, showing that real-world contexts effectively support the understanding of basic arithmetic operations.

Abstract

The purpose of this study was to determine the effectiveness of the SI-BAD application-assisted problem-based learning model in improving students' mathematical problem-solving skills. This study was a pre-experimental quantitative study with a one-group pretest-posttest design conducted in class V of SDN Mangunrejo 1 with a population of 19 students. The sampling technique used in this study was saturated sampling. The data collection techniques used were tests and documentation. The data analysis techniques used were the paired sample t-test and the N-Gain test. The results of the study showed that the SI-BAD application-assisted problem-based learning model was effective and that there was an increase in students' mathematical problem-solving skills after using this model. The results of the paired sample t-test showed that the use of the SI-BAD application-assisted problem-based learning model was effective in improving students' mathematical problem-solving skills. It was found that the percentage of improvement in students' abilities was 60.02%, which is considered quite effective.
