Abstract

This study aimed to develop a science literacy based Student Worksheets on amphibian material to improve students’ science literacy. The research employed a Research and Development (R&D) method using the 3D model consisting of Define, Design, and Develop stages. The study was conducted at one of the schools in Bandung district involving 40 tenth grade students selected through random sampling. Data were collected through interviews, observations, validation questionnaires, and science literacy tests in the form of pretest and posttest. The worksheets was validated by material expert, pedagogical expert, and biology teacher, obtaining validity scores of 61.33%, 90.67%, and 92%, respectively. Based on material expert feedback, revisions were made to improve content accuracy, align science literacy indicators with learning objectives, and clarify learning activities before implementation. The revised worksheets was categorized as valid and highly valid for classroom use. The effectiveness test showed an increase in students’ science literacy, with the average score rising from 39 on the pretest to 77 on the post test. The N-Gain score of 0.59 was categorized as moderate. These findings indicate that the developed worksheets is feasible and effective in supporting biology learning and improving student science literacy.

Abstract

The study aimed to develop science literacy-based Student Worksheets (LKPD) on the topic of insects. This Research and Development (R&D) study employed the 3D model, consisting of the define, design, and develop phases. The study participants included subject matter experts, pedagogical experts, and biology teachers who served as product validators. A pilot test was conducted on 41 students at a high school in Bandung Regency, West Java. Data analysis showed that the Student Worksheets (LKPD) had a high level of feasibility based on validation by subject matter experts (77,3%), pedagogical experts (85,3%), and biology teachers (95%), thus the LKPD was deemed highly suitable for use. The research instrument used was a validation sheet to assess the suitability of the science literacy-based LKPD. The results of the limited pilot test showed an increase in students’ science literacy skills with a score of 0,44, falling into the moderate category. The science literacy-based LKPD on the topic of Insects can be used as teaching material to improve science literacy.
