PENGARUH MEDIA PEMBELAJARAN TANGGA SATUAN PANJANG DAN BERAT TERHADAP KEMAMPUAN LITERASI NUMERASI SISWA SEKOLAH DASAR

Abstract

Mathematics often poses an abstract challenge for elementary school students,
particularly in mastering length and weight unit conversions, which are frequently
memorized rather than conceptually understood. This study aims to bridge this gap
by utilizing the length and weight unit stairs learning media to meaningfully enhance
students' numeracy literacy skills. Employing a quantitative approach with a One
Group Pretest-Posttest design, this study involved 20 fifth-grade students at SDN
029 Tenggarong Seberang selected via purposive sampling. Literacy tests were
administered to observe students' progress before and after the intervention,
followed by N-Gain and paired sample t-test analysis. The findings reveal that
bringing abstract concepts into a concrete, visual space successfully transforms the
classroom atmosphere, making students more active, focused, and less anxious in
understanding unit sequences. The media exerts a significant positive influence on
students' numeracy literacy. In conclusion, learning that prioritizes concrete
experience through unit stairs successfully fosters a deeper conceptual
understanding, proving to be a humanistic yet effective alternative in elementary
mathematics education.
