The Use of Manipulatives in Teaching Grade 8 Mathematics

Abstract

Mathematics is often perceived as a difficult subject due to its abstract nature, making it challenging for students to grasp key concepts, especially at the Junior High School level. This study investigated the effectiveness of manipulatives in teaching Grade 8 mathematics to address low academic performance among students. It aimed to determine the students’ performance before and after the use of manipulatives, compare the results with those taught through traditional methods, and assess the significance of the difference between their scores. As an output, the study proposes the integration of manipulative-based instruction to improve conceptual understanding and enhance overall student achievement in mathematics. This employed a quasi-experimental quantitative design and had 60 grade 8 students of the University of Cebu at Pardo and Talisay. The research involved two groups: an experimental group taught with manipulatives and a control group taught using traditional methods. Pretest and posttest scores were analyzed using the mean, paired, and independent t-tests to determine performance differences within and between groups. Findings revealed that while both groups showed improvement from pretest to posttest, the experimental group exhibited significantly higher gains in mathematical achievement. The posttest scores of students who were taught using manipulatives were notably higher compared to those in the control group, affirming the positive impact of hands-on materials in facilitating conceptual understanding. The study recommends integrating manipulatives in regular instruction to foster student engagement, improve comprehension, and support differentiated learning in mathematics classrooms. Additionally, school administrators are encouraged to provide training and sufficient resources to support the effective use of manipulatives in classroom instruction.
