Abstract

ABSTRACT Mathematics education in elementary schools has a very important role in forming the basis of students' understanding of more complex mathematical concepts at the next level of education. One of the materials taught in grade IV is flat shapes, which includes calculating area and circumference. Many students already know the formula but have not been able to solve the problems faced. This can be seen from the results of previous student learning. The purpose of this study was to determine the effectiveness of the ability of grade IV students of SDN Pati Kidul 03 Pati in determining the circumference and area of ​​​​flat shapes by applying the Problem Based Learning (PBL) model assisted by geoboard media. This study uses a quantitative approach with a pre-experimental design, namely the one-group pretest-posttest design. The population of this study was all grade IV students of SDN Pati Kidul 03 Pati in the 2024/2025 academic year, with a sample of 30 students selected using saturated sampling techniques. The results showed significant improvements in students' understanding of flat shapes, with an average pre-test score of 47 and an average post-test score of 80. The results of the paired t-test confirmed the effectiveness of using geoboard teaching aids, with a t-value of 37.946 > 1.699. The use of geoboard teaching aids can be an alternative media to improve students' understanding of flat shapes, for active and enjoyable learning.
