A Digital Instructional Book: A Tool for Improving Students’ Learning Outcomes on the Reduction and Oxidation Reactions

Abstract

The rapid development of information and communication technology demands the production of digital products. This study aims to produce a digital instructional book based on Balinese local cultures to enhance the learning outcomes of high school students. The development of this book used the ADDIE model. The analysis phase included an analysis of the chemistry curriculum, teachers’ and students’ opinions about digital books, digital learning, and Balinese local cultures related to the chemistry content. The design phase included creating a framework and preparing a digital instructional book based on Balinese local cultures. The development phase included validation by content, language, and media experts. The implementation phase included testing the practicality and effectiveness of the book. The evaluation phase was carried out at all phases of the ADDIE model. The characteristics of this book were that it was made in a digital form and integrated with local Balinese cultures. It met the criteria of being a very valid category based on content, language, and media aspects. It also met a practical and effective category to improve students’ learning outcomes. It is very useful to enhance chemistry learning outcomes in the era of the Industrial Revolution 4.0.
