Application of Group Investigation Model to Improve Students' Social Studies Learning Outcomes

Abstract

This research is motivated by the lack of student activity during the learning process and the use of less varied methods, which results in low learning outcomes. The aim of this study is to improve learning outcomes by using the Group Investigation model. The method used is Classroom Action Research (CAR), conducted in two cycles at SDN 88/II Sungai Mengkuang with 27 student participants during the odd semester of 2023. The results indicate an improvement in both the process and outcomes of learning with the implementation of the Group Investigation model. In Cycle I, activity increased from 48.1% to 59.2%, categorized as active. In Cycle II, the activity percentage increased from 70.3% to 85.1%, categorized as very active. This improvement was accompanied by an increase in student learning outcomes, where test results in Cycle I improved from 40.7% to 62.9% (Very Good) and in Cycle II improved from 74.0% to 88.8% (Very Good). Thus, it can be concluded that the Group Investigation model can enhance student learning outcomes and is considered relevant to current educational needs, thereby improving the quality of classroom learning.
