How to Develop Scientific Literacy Enrichment Book on Earth Science Content Using Plomp Method?

Abstract

The purpose of this study is to produce a book on enriching scientific literacy in Earth Science context that is feasible and appropriate for junior high school students. The development of science literacy enrichment books uses the Plomp method which consists of problem analysis, prototype design and development, evaluation, and revision. In the process of developing the book an instrument is used in the form of a list of indicators which are a combination of material and competencies developed. The material developed includes Atmosphere, Hydrosphere and Lithosphere which includes discussions on environmental pollution, global warming, the water cycle, earthquakes, tsunamis, volcanoes and soil. Competencies developed include the competence to explain phenomena scientifically, interpret scientific data and evidence, and evaluate and design investigations. In the evaluation process the instruments used were questionnaires, readability test instruments and scientific literacy tests. The participating participants numbered 30 of grade 7 students from one of the junior high schools in Cilacap District. The results of the study showed that the developed scientific literacy enrichment book was feasible to use with a percentage of eligibility of 79,2%.
