Abstract

This research was motivated by the low level of students' scientific literacy skills, particularly in remembering and applying scientific knowledge, explaining the potential implications of scientific knowledge, evaluating scientific investigations, and interpreting data. The purpose of this study was to determine the effect of the Problem-Based Learning model assisted by digital flipbook media on the scientific literacy skills of fifth-grade students  in the topic of the human digestive system. The research employed a pre-experimental method using a one-group pretest-posttest design. The sampling technique used was non-probability sampling with a saturated sampling approach. The sample consisted of 26 fifth-grade students. Data were collected through test and non-test techniques using scientific literacy tests and a learning implementation observation sheet as the research instruments. Data analysis techniques included validity testing, reliability testing, normality testing, t-test, and effect size analysis. The results showed that the mean pretest and posttest scores of students' scientific literacy skills were 59 and 79, respectively. The t-test results indicated a Sig. (2-tailed) value of 0.01 < 0.05 in the Paired Samples t-Test with α = 0.05, while the effect size value was 1.22, indicating a high category. The implementation of the learning model achieved a percentage of 100%, which was categorized as very good. Therefore, it can be concluded that the Problem-Based Learning model assisted by digital flipbook media had a significant effect on students' scientific literacy skills in the human digestive system topic for fifth-grade students at SDN Darmaraja I, Darmaraja District, Sumedang Regency, Academic Year 2025/2026, and can serve as an alternative learning approach to improve students' scientific literacy skills.
