PENGEMBANGAN ALAT PERAGA PLACE VALUE BERBASIS SPEDOMATIK UNTUK MENINGKATKAN PEMAHAMAN KONSEP MATEMATIKA SISWA KELAS II SD

Abstract

This study aims to develop a place value learning tool based on "Spedomatik" to
improve the understanding of mathematical concepts in grade II elementary school
students. The research uses the ADDIE development model which includes
Analysis, Design, Development, Implementation, and Evaluation stages. Data
collection techniques included interviews, observations, questionnaires, and tests.
The subjects were 28 second-grade students at SD Islam Insan Taqwa. The
results showed that the developed Spedomatik media met valid, practical, and
effective criteria. This was based on expert validation results with an average
percentage of 81.6% (very valid), teacher and student responses with an average
of 85% (very practical), and student learning outcomes that increased significantly
after the use of the media. Thus, Spedomatik-based place value media is suitable
to be used as a learning aid to enhance students’ conceptual understanding in
mathematics.
