PENGEMBANGAN MEDIA BATUKALI (LUBANG HITUNG PERKALIAN) PADA MATA PELAJARAN MATEMATIKA KELAS II DI SEKOLAH DASAR

Based on the needs analysis observations on November 24, 2018 at Probolinggo Brabe 2 Elementary School, class II students during the learning process tended to be passive to the mathematical competence of multiplication material. This is because the teacher conveys the material that has not been supported by learning media that are fun and interesting to students. The teacher places more emphasis on the ability to memorize numbers than the process of building concepts. The teacher has never developed the media both existing media and developing new media, so the need for media development can help teachers and students in the teaching and learning process. This study aims to develop BATUKALI (Calculating Multiplication) media in Mathematics Material II Grade of Elementary School. This study uses the type of ADDIE development research, namely analyze, design, development, implementation, and evaluation. As a source of data are class II students at SDN Brabe II Probolinggo, with a total of 10 students. Data collection techniques using a validation questionnaire sheet. Before going through the implementation phase, the BATUKALI media was validated by 3 validators, namely material experts, media experts, and teacher responses to determine the effectiveness of the media. The results of the BATUKALI (Multiplication Hole) media study on class II math subjects in Elementary School were with the validity level of 96% and 93% material aspects in the media aspect. After implementation, researchers obtained 97% effectiveness for teacher responses and 97% for students' attractiveness responses with very effective criteria. This shows that with the BATUKALI (Hole Counting Multiplication) media, teachers and students have been helped and increased motivation in learning. The results of this study will produce products in the form of BATUKALI (Multiplication Hole) media on mathematics subjects multiplication so that students learn with fun, creative, and critical thinking
