Development of sound wave and light wave e-book physics based on scientific approach to improve science process skills for secondary school students

Abstract

This study aims to develop Sound Wave and Light Wave e-book based on Scientific approach to improve science process skills for secondary school students, that is suitable to be used as a learning source. The method used in this research is Research and Development (R&D) with Borg and Gall model. The steps are preliminary research, model development planning, validation, evaluation, revision and implementation. This e-book is developed based on scientific approach, which consists of introduction, concept development, application in real life, concept reinforcement, and evaluation. This e-book has been validated with average score of 98% by material experts, 82% by media experts, and 80% by learning experts. Based on the assessment of the effectiveness in the experimental class, the average score of pretest and posttest obtained were 44.38 and 76.1, with N gain score of 0.55. Overall, this e-book is feasible to be used as a learning media and can improve students' science process skills in sound wave and light wave subject.
