Systematic Literature Review: The Effectiveness of the Group Investigation (GI) Learning Model Assisted by Manipulative Media on Mathematics Learning

Abstract

Mathematics learning should be designed with strategies that foster students' critical thinking and collaborative skills, as well as conceptual understanding. However, in reality, the mathematics learning process in the classroom still focuses heavily on procedural aspects. Teachers tend to emphasize problem-solving exercises without optimizing the use of manipulative media to deepen conceptual understanding. One approach considered effective in addressing this problem is the Group Investigation (GI) cooperative learning model, especially when combined with manipulative media that can help students represent abstract concepts concretely. This study aims to identify and analyze the effectiveness of implementing the GI model, supported by manipulative media, in mathematics learning using a Systematic Literature Review (SLR) approach. The research method was conducted by reviewing various scientific articles from national and international databases using strict inclusion and exclusion criteria to ensure the relevance and quality of the sources. The results of the study indicate that the use of the GI model, supported by manipulative media, consistently improves students' mathematics learning at various levels of education. Therefore, this study recommends the implementation of the GI model assisted by manipulative media as an innovative alternative in mathematics learning that focuses on active and in-depth learning experiences.
