Abstract

Penelitian ini dilatarbelakangi oleh rendahnya kemampuan matematika anak kelas I sekolah dasar dalam memahami konsep membandingkan dua bilangan. Tujuan dari penelitian ini untuk mendeskripsikan peningkatan hasil belajar matematika siswa kelas I melalui penerapan model contextual teaching and learning. Subjek penelitian ini adalah siswa kelas I C yang berjumlah 28 orang. Rancangan penelitian tindakan kelas ini menggunakan model Kemmis dan Mc Taggart. Teknik pengumpulan data dalam penelitian ini menggunakan lembar observasi, lembar tes, dan dokumentasi selama pembelajaran. Perkembangan proses pembelajaran dari siklus I ke siklus II mengalami peningkatan, baik dari segi aktivitas guru dan siswa selama pembelajaran maupun hasil belajar siswa. Aktivitas guru pada siklus I ke siklus II mengalami peningkatan sebesar 11,77% dari 76,47% menjadi 88,24% dan aktivitas siswa mengalami peningkatan sebesar 17,31% dari 67% menjadi 84,31%. Selain itu, ketuntasan hasil belajar siswa secara klasikal dari siklus I ke siklus II juga mengalami peningkatan sebesar 17,86% dari 75% menjadi 92,86%. Berdasarkan hasil penelitian tersebut, dapat disimpulkan bahwa model pembelajaran contextual teaching and learning dapat meningkatkan hasil belajar siswa pada muatan matematika Tema 5 Subtema 3

Abstract

This study aims to analyze the application of the Problem Based Learning (PBL) model based on educational games in improving mathematics problem solving skills in class 1C students at SDN Kauman 1 Malang City. This research approach uses descriptive qualitative methods with data collection techniques in the form of observation, interviews, and documentation. The results showed that the application of PBL based on educational games can significantly improve students' ability to identify, formulate, and solve mathematical problems. This model also increases motivation, participation, and critical thinking and collaboration skills among students. Educational games that are designed to help students understand mathematical concepts in a real context can also create fun and meaningful learning, in line with constructivist learning theory. Obstacles such as differences in student understanding and time constraints can be overcome with intensive assistance and simplification of the games. This study also concluded that PBL based on educational games is an innovative approach that is effective in improving problem solving skills and student engagement.

Abstract

This study aims to explore the implementation of Problem-Based Learning (PBL) on the topic of "Rules and Safe Play Areas" to enhance science and technology literacy among first-grade students in class 1C at SD Negeri Kauman 1. The research uses a Classroom Action Research (CAR) design, conducted in two cycles involving planning, implementation, observation, and reflection. The results show that the application of PBL significantly increases student engagement and understanding of science concepts related to safety in play. In the first cycle, students faced challenges in connecting scientific concepts with real-life safety rules. However, improvements were made in the second cycle, where clearer connections were established, leading to better participation and understanding. The study concludes that PBL can effectively improve science and technology literacy in early-grade students.
