Skripsi, Fakultas Keguruan dan Ilmu Pendidikan Universitas Sebelas Maret Surakarta. Mei 2018. Tujuan penelitian ini adalah (1) mendeskripsikan penerapan model group investigation dalam peningkatan kerja sama dan pemahaman konsep IPA materi gaya; (2) meningkatkan kerja sama siswa; (3) meningkatkan pemahaman konsep IPA materi gaya; dan (4) mendeskripsikan respon siswa terhadap pembelajaran IPA materi gaya melalui penerapan model group investigation. Penelitian ini merupakan penelitian tindakan kelas (PTK) kolaboratif yang dilaksanakan dalam tiga siklus. Setiap pertemuan terdiri dari empat tahapan, yaitu: perencanaan, pelaksanaan, observasi, dan refleksi. Subjek penelitian ini adalah siswa kelas V yang berjumlah 26. Sumber data penelitian ini yaitu guru dan siswa. Teknik pengumpulan data menggunakan tes, observasi, wawancara, dan angket. Uji validitas data menggunakan teknik triangulasi. Analisis data yang digunakan adalah teknik analisis data kualitatif dan analisis data kuantitatif. Hasil penelitian ini menunjukkan bahwa (1) penerapan model group investigation (GI) dilakukan dengan langkah pemilihan topik dan pengelompokkan (grouping), perencanaan kerja sama (planning), penyelidikan (investigation), analisis dan sintesis, presentasi hasil (presenting), dan evaluasi (evaluating); (2) penerapan model group investigation dapat meningkatkan kerja sama siswa kelas V SD Negeri 1 Selang, hal ini diketahui dari penelitian yang menunjukkan bahwa pada siklus I persentase siswa yang memenuhi capaian target kerja sama yaitu 65,4%, siklus II 80,8%, dan siklus III 84%; (3) penerapan model group investigation dapat meningkatkan pemahaman konsep IPA materi gaya siswa kelas V SD Negeri 1 Selang yang, hal ini diketahui dari ketuntasan pemahaman konsep siswa pada siklus I sebesar 73,5%, pada siklus II sebesar 55,8%, dan pada siklus III sebesar 84,6%. Selain itu, kemampuan kognitif siswa sangat baik untuk jenjang kognitif C1 dan C2. Kemampuan kognitif siswa pada jenjang kognitif C3 dan C4 masih dalam kategori sangat rendah; (4) respon siswa terhadap pembelajaran IPA menggunakan model group investigation pada umumnya lebih semangat daripada menggunakan metode ceramah. Siswa menanggapi positif pembelajaran IPA, merasa senang dengan cara guru menyampaikan materi pelajaran dan suasana belajar yang baru di kelas. Kesimpulan dari hasil penelitian ini adalah penerapan model group investigation dapat meningkatkan kerja sama dan pemahaman konsep IPA materi gaya di kelas V SD Negeri 1 Selang tahun ajaran 2017/2018.

THE IMPLEMENTATION OF GROUP INVESTIGATION (GI) MODEL IN IMPROVING COOPERATION AND CONCEPT UNDERSTANDING OF NATURAL SCIENCE LEARNING ABOUT FORCE FOR THE FIFTH-GRADE STUDENTS OF SD NEGERI 1 SELANG IN THE ACADEMIC YEAR OF 2017/2018. Thesis, Teacher Training and Education Faculty, Sebelas Maret University of Surakarta. May 2018. The objectives of this research are: (1) to describe the application of Group Investigation model in improving students’ cooperation and concept understanding of natural science; (2) to improve students’ cooperation; (3) to improve concept understanding of natural science about force; and (4) to describe the response of the students on the learning of natural science about force through the use of Group Investigation model. This research is a collaborative Classroom Action Research (CAR) conducted within three cycles. Each cycle consisted of planning, action, observation, and reflection. Subjects of the research were 26 students of the fifth grade. The data source of this research are teachers and students. Data collection techniques used are tests, observations, interviews, and questionnaires. Test of validity of data using triangulation techniques. Techniques of data analysis are qualitative data analysis techniques and quantitative data analysis. The results of this research indicated that: (1) the application of Group Investigation model was conducted through stages as follows: choosing topic and group division, planning of collaboration, investigation, analyzing and synthetic, presenting the result, and evaluating; (2) the application of Group Investigation model can improve students’ cooperation on the fifth-grade students of SD Negeri 1 Selang. In fact, the results of this research show that the percentage of students who meet the target achievements of cooperation is 65.4% in the first cycle, in the second cycle 80.8%, and in the third cycle 84%; (3) the application of Group Investigation model can improve concept understanding of natural science about force for the fifth-grade students of SD Negeri 1 Selang. In fact, the result of learning outcomes concept understanding of natural science is 73.5% in the first cycle, in the second cycle 55.8%, and in the third cycle 84.6%. Moreover, students’ cognitive ability are very good for cognitive level C1 and C2. Meanwhile, students’ cognitive ability for cognitive level C3 and C4 is still categorized very low; and (4) generally, the response of the students about the learning of natural science the implementation of Group Investigation model is more enthusiastic than the implementation of lecture method. Students give positive feedback about the learning of natural science, feeling comfortable with the way the teacher deliver lessons and new learning experience in the classroom. The conclusion of this research is the implementation of Group Investigation model can improve cooperation and concept understanding of natural science about force for the fifth-grade students of SD Negeri 1 Selang in the academic year of 2017/2018.
