Abstract

The low mathematics learning outcomes among elementary school students, particularly in the topic of decimal numbers, are caused by a lack of active student engagement, limited variation in teaching methods, and minimal integration of technology in the learning process. The aim of this study is to analyze the effectiveness of the Project-Based Learning (PjBL) model assisted by the digital media Mentimeter in improving elementary students' mathematics learning outcomes on the topic of decimal numbers. This research employed a quasi-experimental method with a pre-test post-test control group design, involving 186 fourth-grade elementary school students. The sample was selected through random sampling, with Class IV A as the experimental group (27 students) and Class IV B as the control group (15 students). Data were collected through observation, interviews, tests, and documentation. A t-test was used to analyze the data. The t-test results showed that among the 32 tested students, the tvalue was 7.074 and the ttable was 1.683, indicating that the null hypothesis (Ho) was rejected and the alternative hypothesis (H1) was accepted, revealing a significant difference between the two groups. This study implies the importance of integrating project-based learning models with the support of interactive digital media such as Mentimeter to create a more engaging, participatory, and meaningful learning experience for elementary school students, especially in mathematics education.

Abstract

Penelitian ini bertujuan untuk menghasilkan media pembelajaran interaktif berupa PPTX inovatif berbantuan edpuzzle untuk mata pelajaran IPAS kelas IV di Gugus VI, Kecamatan Sawan  yang valid dan praktis. Metode penelitian yang digunakan adalah Research and Development (penelitian dan pengembangan) dengan model pengembangan ADDIE (Analysis, Design, Development, Implementation, dan Evaluation). Model ADDIE yang digunakan dibatasi sampai tahap Implementation karena keterbatasan waktu. Teknik pengumpulan data yang digunakan meliputi wawancara dan penggunaan kuesioner. Hasil penelitian menunjukan bahwa media pembelajaran PPTX inovatif berbantuan edpuzzle memperoleh nilai validitas tinggi, yaitu 0,8 untuk ahli bahasa, 0,9 untuk validitas media dan materi. Pada uji kepraktisan menggunakan angket dengan responden lima orang guru kelas IV dan 20 peserta didik. Hasil kepraktisan memperoleh skor 94% pada uji kepraktisan praktisi dan 93,9% pada uji kepraktisan peserta didik. Dari data tersebut, penelitian pengembangan media pembelajaran PPTX inovatif berbantuan edpuzzle untuk materi indonesiaku kaya budaya pada mata pelajaran IPAS dengan kategori sangat layak dan sangat praktis digunakan
