Development of Science Technology Society (STS)-Based Physics Student Worksheet to Improve Students’ Science Literacy

The research on the development of Science Technology Society (STS)-based physics student worksheet has been conducted. This study aims to: (i) produce valid STS-based physics student worksheets, (ii) analyze the practicality of STS-based physics student worksheets, and (iii) analyze the effectiveness of STS-based physics student worksheets on students’ science literacy at SMAN 4 Gowa. The research method is Research and Development (R&D) with 4D model. The subjects of this research trial were 35 students of class XI IPA 1 at SMAN 4 Gowa. The instruments used include validation sheets, practitioner assessment questionnaires, and science literacy test instruments. Validity criteria based on expert validation results analyzed with Aiken's Index. Practicality criteria based on practitioners’ assessment result. Effectiveness criteria based on students' science literacy test result analyzed with N-gain equation. The results showed: (i) The validity of STS-based physics student worksheets meets the valid criteria with an expert agreement index (V) of 0.80, (ii) The practicality of STS-based physics student worksheets meets the practical criteria with a percentage of practitioner assessment of 91.88% in the very practical category, (iii) The effectiveness of STS-based physics student worksheets on science literacy of SMAN 4 Gowa students meets the effective criteria with an N-gain score of 0.42 in the medium category. Based on this research, it can be concluded that STS-based physics student worksheets are valid, practical, and effective in terms of improving students' science literacy.
