Development of E-Supplement Teaching Materials Based on Socio-Scientific Issues on Environmental Change Material to Improve Process Skills and Science Literacy of High School Students

Abstract

The results of PISA in 2018 indicate that students' scientific literacy in Indonesia needs to be improved. Current teaching materials focus more on the content of the material and have not been linked to real-life contexts. To support the improvement of scientific literacy, teaching materials related to social issues are developed that can train students in improving science process skills and science literacy. The purpose of this study is to develop e-supplement teaching materials based on Socio-Scientific Issues to improve science process skills and students' science literacy. This study is a Research and Development (R&D) study referring to the steps including (1) potential and problems (2) data collection (3) product design (4) design feasibility assessment (5) design revision (6) product trial (7) product revision (8) usage trial. The results of the study indicate that the e-supplement teaching materials used in learning are in the criteria for being suitable for use, with material validity of 85%, media validity of 100%, teacher responses of 85%, and student responses of 88%. The use of e-supplement teaching materials effectively improves students' science process skills and science literacy, with the results of N-gain Science Process Skills in both classes of 0.67, and the results of N-gain science literacy in the two classes of 0.59 and 0.49. From the results of the study, e-supplement teaching materials based on Socio-Scientific Issue are valid as teaching materials in learning Environmental Change material. E-supplement teaching materials based on Socio-Scientific Issue are effective in improving students' science process skills and science literacy in Environmental Change material.
