Validation of audio-based solar system visual aid for special school students

Abstract

Making and testing of miniature solar systems intended for students has been carried out and specifically for special school students. The purpose of making this tool is to help the learning process in students with special needs for science materials, especially in the solar system. The solar system visual aid consists of sun with its planets, including from Mercury to Neptune. Planets were designed to move automatically. In addition, this visual aid was also made audio containing explanations for each planet and also the sun. Validation of tools is carried out by material and media experts. The results of the material validation are good. While the media validation is sufficient and received well. This audio-based solar system visual aid is good enough to be used by special school students.
