Abstract

Rendahnya hasil belajar siswa akibat kurang aktifnya siswa mengikuti pembelajan menjdai salah satu alasan penelitian ini dilakukan. Penelitian ini bertujuan untuk mengetahui pengaruh yang signifikan model pembelajaran group investigation (GI) berbasis tri hita karana terhadap hasil belajar IPA. Penelitian ini merupakan penelitian eksperimen semu (quasi eskperimen) dengan desain non equivalent post test only control group desain. Populasi dalam penelitian ini adalah seluruh siswa kelas V SD jumlah 139 orang. Pengambilan sampel dilakukan dengan teknik simple random sampling. Sampel dalam penelitian ini adalah SD Bayunggede berjumalah 29 orang (ekperimen) dan SD Sekaan berjumlah 25 orang (kontrol). Teknik analisis yang digunakan adalah analisis deskriptif dan uji-t. Hasil perhitungan rata-rata skor hasil belajar IPA siswa yang diberikan perlakuan model pembelajaran group investigation (GI) berbasis tri hita karana 19,62 termasuk ke kategori sangat baik, sedangkan siswa yang dibelajarkan model pembelajaran konvensional memiliki rata-rata skor hasil belajar IPA 15,16 termasuk ke kategori baik. Sehingga berdasarkan temuan tersebut, dapat disimpulkan bahwa model pembelajaran group investigation (GI) berbasis tri hita karana berpengaruh positif terhadap hasil belajar IPA. Model ini bisa dijadikan sebagai pilihan oleh guru digunakan sebagai alternative dalam proses pembelajaran.

Abstract

This research was carried out due to the lack of use of varied teaching materials, causing a lack of scientific literacy and problem-solving skills of students in learning. This study aims to analyze the design, validity, practicality, and effectiveness of project-based learning-based modules to improve scientific literacy and problem solving in plant development materials. This research is development research using the 4D model (Four D Model). The subjects of this study were material experts, media experts, educators, and third grade elementary school students. Data collection methods used are interviews, documentation, and questionnaires. The type of instrument used is a closed questionnaire. Data collection techniques used are qualitative analysis techniques and quantitative analysis techniques. The results of this study indicate the results of the calculation of the effectiveness test on the overall scientific literacy ability using N-gain with a g value of = 0.74 with a high level of effectiveness. The results of the effectiveness test on overall problem-solving ability using N-gain obtained a g value of = 0.71 with a high level of effectiveness. Thus, the project-based learning module developed with the 4D model is valid, practical, and effective to be used as teaching materials. The implication of this research is that the project-based learning module developed is valid, feasible, and effective for use in learning.
