Group Investigation Model in Environmental Learning: An Effect for Students' Higher Order Thinking Skills

Group investigation is a learning model that emphasizes the ability to think of students through group activities to investigate specific problems or topics. Solving problem needs an Higher Order Thinking Skills (HOTS). This is because the problem needs to be solvedwith problem analysis and evaluation, based on the competency of the students. Through this model, students can be directly involved in solving the problems encountered. This study aimed to determine the effect of the group investigation learning model on students’ HOTS in environmental learning for the topic of environmental pollution. The method used in this research was an experiment with a post-test only control group design. The sample of the research was 10th grade students selected by simple random sampling. The results of the study showed that t-count > t-table, which could be interpreted as an effect of the group investigation learning model on students' HOTS. The group investigation learning model made students more active and exercised their ability to analyze students. The conclusion of this study was that there was an influence in students’ HOTS on the use of the group investigation model.
