This study aims to describe the design, feasibility, and practicality of, as well as the improvement in, scientific argumentation skills through E-LKPD based on Problem-Based Learning oriented toward socio-scientific issues. The study employed the Research and Development (R&D) method using the 4-D model, which includes the analyze, design, development, and dissemination stages. In the Define stage, an analysis of students’ needs, learning characteristics, and redox chemistry content was conducted. In the Design stage, the E-LKPD was designed by integrating PBL syntax, socio-scientific issues, and scientific argumentation activities. In the Develop stage, the E-LKPD was validated by content and media experts and tested for practicality at SMAN 5 Malang. The validation results indicated that the E-LKPD was highly valid, with content and media validation scores of 93.58% and 93.80%, respectively. Student and teacher responses yielded scores of 85.07% and 96.72%, respectively, indicating a very high level of practicality. Furthermore, a trial involving 30 tenth-grade students resulted in an N-gain score of 0.64, categorized as moderate, indicating an improvement in students’ scientific argumentation skills. In the Disseminate stage, the developed E-LKPD was distributed to SMAN 5 Malang and other senior high schools in Malang City. The product was also made available through the TopWorksheets platform to broaden access to contextual digital learning materials. Overall, the developed E-LKPD demonstrated high validity and practicality and has the potential to train students’ scientific argumentation skills in redox chemistry learning.
