PENGARUH MEDIA KONKRET TERHADAP HASIL BELAJAR SISWA PADA MATERI BANGUN RUANG DI KELAS II SD

Abstract

This study aims to determine the effectiveness of using concrete media to improve
student learning outcomes in the topic of three-dimensional shapes among
second-grade students at SDN Bangunrejo Lor 1, Pitu District. This research
employed a quantitative approach using a pre-experimental design of the One
Group Pretest-Posttest type. Data were collected through multiple-choice tests
administered before and after the treatment. Data analysis was carried out using
SPSS version 26, applying the Kolmogorov-Smirnov normality test and the paired
sample t-test for hypothesis testing. The results showed a significance value (2-
tailed) of 0.000 < 0.05 and a t-count of 11.856 > t-table value of 2.045, indicating a
significant difference between pretest and posttest scores. These findings suggest
that the use of concrete media effectively enhances students’ understanding and
learning outcomes. Observations in the classroom revealed that many students
encountered difficulties in grasping the abstract concepts of three-dimensional
shapes due to the dominance of teacher-centered learning and the lack of
engaging instructional media. The use of concrete media, such as three-
dimensional teaching aids, provides visual and tangible representations of
geometric concepts, making it easier for students to comprehend the material. In
addition, this approach fosters greater student engagement, motivation, and active
participation in the learning process. Therefore, it is recommended that concrete
media be incorporated into mathematics instruction to create a more interactive
and meaningful learning environment.
