Development of an SSCS-Based Electronic Student Worksheet (E-LKPD) Integrating Science Process Skills in Respiratory System Learning

Abstract

Biology learning in secondary schools is still dominated by printed materials or simple files that have not been integrated with interactive digital technology and do not emphasize the development of science process skills. This situation results in students not receiving an optimal learning experience. This study aims to develop an Electronic Student Worksheet (E-LKPD) based on the Search, Solve, Create, and Share (SSCS) model for the respiratory system to practice students' science process skills. This study used a Research and Development (R&D) method with a 4D development model that includes the define, design, and develop stages. The research subjects included a material expert validator, a media expert validator, two biology teachers, and 35 grade 11 students from SMAN 10 Kota Depok. The research instruments were a validation questionnaire and a user response questionnaire. Data were analyzed descriptively and quantitatively. The results showed that the developed E-LKPD received a feasibility rating of 78% from subject matter experts, indicating "feasible," and 82% from media experts, indicating "very feasible." Teacher and student responses were 92% and 98%, respectively, categorizing it as "very feasible." Based on these results, the SSCS-based E-LKPD was deemed suitable for use as an innovative teaching material that supports interactive, meaningful learning and has the potential to improve students' science process skills.
