Development of Mobile Media “GeMBul” in Science Learning: The Validity and Reliability Study

Abstract

The development of technology 4.0 affects learning and teaching in schools, especially with the COVID-19 pandemic, which requires teachers and students to use technology. This study aims to develop mobile media on solar and lunar eclipse material, abbreviated as "GeMBul," which can assist teachers in teaching concepts. Students can repeat learning materials anytime and anywhere. The development of mobile media "GeMBul" was developed using the ADDIE model (analysis, design, development, implementation, and evaluation). Validation was carried out by three material experts and one media expert with 78.33 and 76. The mobile media "GeMBul" was valid/feasible to use in science learning. The limited trial of mobile media "GeMBul" to students and teachers obtained 91 and 94 with excellent categories. Reliability data were obtained from a multiple-choice test of conceptual understanding and technological literacy as many as 22 questions to 75 junior high school students in Surabaya. The reliability results stated that the test was declared reliable to measure students' conceptual understanding and literacy with high criteria. The responses of students and teachers to the "GeMBul" application in terms of the practicality of using the "GeMBul" application obtained data that students and teachers stated that the "GeMBul" application was efficient to use in science learning with scores of 83.96 and 90.

A Review Analysis: Implementation of STEAM Project Based Learning in Science Learning

“…Kementrian Pendidikan dan Kebudayaan (Kemendikbud), mendefinisikan pendidikan harus mampu memenuhi tuntutan kerja pada abad 21. Salah satu upaya yang dilakukan oleh Negara Indonesia adalah dengan pengintergrasian antara kecapakan pengetahuan, sikap, keterampilan, serta penguasaan teknologi informasi dan komunikasi (Kasmita et al, 2021;Ramdani et al, 2019). Pendidikan abad 21 bertujuan untuk membawa individu ke dalam masyarakat sebagai pribadi yang bertanggung jawab, kreatif, memiliki harga diri yang tinggi dan mampu menggunakan ilmu pengetahuan (BALAY, 2004;Kiremit, 2006).…”
