Validity of Teaching Materials Based on Socio-Scientific Issues Approach on the Topic of Vibration, Waves, and Sound

Abstract

Participation in TIMSS and PISA showed that the achievements of Indonesian children are still under the average and low in the scientific literacy. Scientific literacy is the ability to make decisions about scientific issues and scientific phenomena that can be applied in daily life. This ability can be developed using innovative learning approaches such as socio-scientific issues (SSI). SSI is an approach that represents issues or problem in social life that are conceptually related to science. The material discusses on the topic of vibration, waves, and sound because it related to scientific issues and phenomena in daily life. This study aims to describe validity of teaching materials based on socio-scientific issues approach including Syllabus, Lesson Plan, Students' Book, Students' Worksheet, and Scientific Literacy Test. The data are then collected through validation questionnaire to assess validity of teaching materials. Data collection instruments used validation sheets. The data are analysed by using both descriptive quantitative and qualitative methods. The result of teaching materials validation showed that teaching materials is very valid and can be used for learning process.
