Developmental Scratch-Based Online Learning Media in Dynamic Electric Dynamic Topic to Increase Students Concept Understanding in Students Junior High School

Abstract

The purpose of this research is to design and develop learning media, test the validity and reliability of the media and know the effectiveness of scratch-based online learning media on dynamic electrical materials in improving understanding Junior high school students concept. The research and development is based on 4D model consisting of four steps, namely definition, design development, and dissemination. Methods of collecting data using questionnaires, tests and documentation. This scratch-based online Media consists of headers, menus, contents, and footers. In the header there is a title from the Web and dynamic electricity, then the Top menu consists of (home, download, video, map, about, help), while in the section "main Menu" consists of (Home, syllabus, core competencies/basic competencies, and Indicators), material (electrical current, different potential, OHM's law and electrical resistance, and reference sections consist of material sources. To access this online media users just click on the site www.noftianatesis.com. When the site is opened then the user does not need to login first, some features are available at the address, live click and Live View visible. So it can be concluded that the research results with this program can help students to understand the concept of physics that are still abstract and students feel interested in learning to use a learning media program with Scratch-based animations.
