OPTIMALISASI HASIL BELAJAR SISWA MELALUI PENGEMBANGAN MEDIA PEMBELAJARAN TIGA DIMENSI ( DUPOPIN ) PADA MATERI PENJUMLAHAN DAN PENGURANGAN KELAS 1 SDN BULUSARI 3

Abstract

The results of observations made in class 1 at SDN Bulusari 3 showed that students experienced difficulties in addition and subtraction material due to a lack of learning media. This study aims to develop three-dimensional mathematics learning media with R&D (ADDIE model). The data collected includes the validity, practicality, and effectiveness of learning media. The validation of material experts and media experts resulted in an average score of 88%, teacher responses achieved an average score of 88%, while student responses in limited and wide trials achieved an average score of 92% and 95%. Media effectiveness was assessed through a post-test. In the limited trial, the pre-test average was 40 and the post-test was 83. In the wide trial, the pre-test average was 44 and the post-test was 83. The statistical analysis of the Paired Sample-t Test showed a result of 0.001 % <0.05%, indicating a significant difference between the pre-test and post-test, proving that three-dimensional learning media is effective in improving student learning outcomes.
