Investigating the Effectiveness of the SAVI Learning Approach in Improving Critical and Analytical Mathematical Thinking

Background: Students’ ability to think critically and analytically in mathematics remains a central challenge in Indonesian education. Many instructional approaches in schools fail to adequately stimulate higher-order thinking. Traditional expository models, although commonly used, often lack the engagement required to foster meaningful learning. The SAVI (Somatic, Auditory, Visual, Intellectual) learning model offers an integrated and interactive alternative by combining physical activity, auditory input, visual aids, and intellectual reflection, aligning with multiple learning modalities. Aims: This study aims to determine the effectiveness of the SAVI instructional approach in improving students’ mathematical critical and analytical thinking skills. It specifically compares the outcomes of students taught using the SAVI model with those instructed through conventional expository teaching. Methods: A quasi-experimental research design with a posttest-only control group was used. The participants were 60 eighth-grade students from SMP Negeri 1 Mataram Baru during the 2023/2024 academic year. Students were divided into two groups: one receiving instruction via the SAVI approach and the other using the expository model. Essay-based assessments were used to evaluate students' critical and analytical thinking skills. The instruments were previously tested for validity and reliability. Data analysis was performed using Multivariate Analysis of Variance (MANOVA) to evaluate differences between the two groups. Results: The results showed a significant difference in student performance between the two groups. Students in the SAVI group demonstrated higher scores in both critical and analytical mathematical thinking. MANOVA results revealed statistically significant values (p < 0.05), confirming the effectiveness of the SAVI model over the expository method. Conclusion: The SAVI instructional model significantly enhances students’ critical and analytical thinking in mathematics. Its multisensory design promotes deeper cognitive engagement, making it a promising approach for improving mathematical thinking at the secondary school level.
