Abstract

The persistently low IPAS (Science and Social Studies) learning outcomes among elementary school students necessitate serious attention in educational practices. This study aimed to investigate the effectiveness of an inquiry learning model utilizing the Lake Tondano environment in enhancing the IPAS learning outcomes of fifth-grade elementary school students. Employing a quasi-experimental design with a pretest-posttest non-equivalent control group, the research utilized objective tests and learning activity observation sheets as instruments, both of which had undergone validation. The findings indicate that the inquiry learning model leveraging the Lake Tondano environment significantly improved students' IPAS learning outcomes. Students participating in this learning demonstrated enhanced understanding of ecosystem concepts and critical thinking skills, alongside increased awareness of environmental issues. This learning model proved effective not only in boosting IPAS achievement but also in providing a more profound and immersive learning experience for students.

Abstract

Penelitian ini dilakukan dengan tujuan meningkatkan hasil belajar matematika siswa kelas IV mengenai topik pecahan melalui penerapan model Problem Based Learning di Sekolah Dasar Katolik III St. Fransiskus Xaverius Woloan. Penelitian ini mempergunakan metodologi Classroom Action Research (CAR), yang dijalankan di dua siklus berbeda. Tiap siklus tersusun atas empat fase kegiatan berurutan, yakni tahapan perencanaan, pelaksanaan tindakan, observasi, serta refleksi. Peserta penelitian ialah 18 siswa, dengan 7 perempuan serta 11 laki-laki. Data didapat dengan dengan mempergunakan instrumen penilaian serta observasi. Analisis data dijalankan melalui penerapan metrik Normalized Gain (N-Gain) untuk memastikan peningkatan kinerja akademik siswa. Pada siklus pertama, persentase keterlibatan pembelajaran mencapai 61.11%, dengan nilai N-Gain 0,40, mengkategorikannya dalam kisaran sedang. Mengikuti peningkatan yang diamati pada siklus kedua, persentase keterlibatan pembelajaran naik menjadi 88,88%, disertai dengan skor N-Gain 0,77, yang berada dalam kisaran tinggi. Hasil itu membuktikan jika implementasi model PBL secara signifikan berkontribusi pada kemajuan hasil pembelajaran matematika siswa mengenai konsep pecahan.
