“…According to Suyanto (2012) group investigation type is a cooperative model that guides students to solve problems critically and scientifically and facilitates students to learn in small heterogeneous groups, to discuss and solve a problem assigned by the teacher to students, so that students able to think systematically, critically, actively participate in learning and have a creative culture through problem solving activities in the learning process through group investigations, students will learn actively. Students are involved since planning, both in determining the topic and the way to learn it through investigation (Chusni, Mahardika, Sayekti, & Setya, 2017). In short, this model is designed to guide students to define problems, explore various horizons about the problem, gather relevant data, develop and test hypotheses (Baharu, 2020).…”
