Development of Student Worksheets (LKPD) Based on Socio-Scientific Issue (SSI) on Flat Form Topics to Improve Reading Literacy and Numeration Skills

This study explores the development and effectiveness of student worksheets (LKPD) based on Socio Scientific Issues (SSI) to enhance reading literacy and numeracy skills among fifth-grade students. Conducted at SDN Jabontegal, SDN Lebaksono, and SD Islam Nahrul Ulum, the research identifies the challenges faced by students in implementing independent learning policies and the inadequacy of existing teaching materials in improving literacy and numeracy. The LKPD was designed to integrate reading and numeracy skills through contextual issues related to the students’ environment, such as historical events and objects in Mojokerto. Validity and reliability tests, involving expert validators in material, language, and media, confirmed the LKPD’s high validity and reliability, with scores of 86%, 83%, and 90%, respectively. The effectiveness of the LKPD was demonstrated through significant improvements in students’ literacy and numeracy skills, as evidenced by N-Gain scores of 0.82 in the experimental class, compared to 0.65 and 0.47 in control classes. Student and teacher responses indicated high levels of agreement on the practicality and readability of the LKPD, with percentages ranging from 72% to 100%. These findings suggest that the SSI-based LKPD is a practical and effective tool for enhancing literacy and numeracy skills in primary education.
