Application of the Group Investigation Learning Model to Increase Learning Outcomes of Junior High School Students in Science Lessons for Materials on Characteristics of Living Things

Abstract

The background of this research is the low learning outcomes of students in science subjects. The purpose of this study was to describe the application of thelearning model Group Investigation (GI) and improve science learning outcomes for seventh grade students of SMP Negeri 1 Umbu Ratu Nggay. The research method used is a group discussion method using an interactive strategy and analyzed using a quantitative approach. This research is a Classroom Action Research (CAR) which is carried out in pre-cycle activities, cycle I and cycle II consisting of planning, action implementation, observation, and reflection. The subjects of the research were 25th graders of class VII. The results showed that the application of the learning model GI could improve student learning outcomes in science subjects at SMP Negeri 1 Umbu Ratu Nggay. This increase can be seen during the pre-cycle, cycle I and cycle II through the learning carried out. The increase in student learning outcomes in the pre-cycle stage was worth 36%, the first cycle reached 64% and increased in the second cycle to 92%. In line with the increase in student learning outcomes by applying the GI learning model, this is similar to the observation of student learning activities at SMP N 1 Umbu Ratu Nggay class VII in science subjects material characteristics of living things through the GI learning model. Because it uses the GI learning model. Practical benefits are expected to add teacher references in implementing learning models that increase student participation.
