21st century education demands strong science literacy skills; however, students often struggle to apply scientific concepts to environmental issues due to teacher-centered instruction and a lack of interactive media. This study aims to determine the effectiveness of the Problem-Based Learning (PBL) model, supported by the Liveworksheet e-LKPD, in improving students’ science literacy in the subject of biodiversity. The research method used was a quasi-experimental design with a pretest-posttest non-equivalent control group design, involving 60 tenth-grade students divided equally into experimental and control groups. Data were collected using a validated two-tier multiple-choice test and analyzed using an independent t-test and Cohen’s d. The results showed that the experimental group achieved a significantly higher average posttest score (73.43) and N-Gain (0.65) compared to the control group (62.60 and 0.49, respectively). Statistical analysis confirmed a significant difference (p=0.001) with a large effect size (d=1.827). In conclusion, the integration of PBL with the interactive Liveworksheet E-LKPD is highly effective in improving science literacy compared to conventional Discovery Learning. Consequently, educators are advised to adopt interactive digital platforms combined with contextual problem-solving to foster scientific reasoning and active student engagement.
