The development of electrical energy conversion tools as learning media for the concept of energy sources

Abstract

Abstract The purpose of this research is to produce electrical energy conversion tool as a learning medium. This research process is a research and development research which is commonly referred to as R&D. Sugiyono modified this research model. The instrument used was a questionnaire with a Likert scale which were assessed by media experts, material experts, physics teachers and students of Grade XI IPA Senior High School Lab school, Untad, Palu. The product quality data obtained were analyzed using descriptive analysis. The product quality based on the results of the analysis of the media expert’s assessment obtained a percentage value of 84% with the interpretation of “Very Good”. The product quality, based on the results of the assessment analysis by material experts, obtained a percentage value of 85% with the interpretation “Very Good”. For the results of the physics teacher responses on the perspective of the learning media developed, it obtained a percentage value of 92.2% with the interpretation “Strongly Agree”. For the results of the students’ responses in Grade XI Science Senior High School Lab school, Untad, Palu, on the limited test, the percentage value obtained was 85.95% which had the interpretation of, “Strongly Agree” regarding the use of the learning media. The results of the tests and questionnaire analysis indicated that the electric energy conversion tool as a learning medium developed is suitable for use in the learning process.
