The research instrument consisted of essay-based questions to assess scientific literacy.The data analysis methodologies employed were N-gain statistical test, normality test and effect size. The effect size technique to measure the effectiveness E-LKPD based on PBL can increase scientific literacy. Based on the study’s findings, shows that there is an average distinction before and after the implementation of E-LKPD founded on PBL. Students in the medium category obtained an increase in scientific literacy with a N-gain value of 0.56. Meanwhile, the effect size value obtained a value of 0.62 in the high category. Thus, E-LKPD based on PBL is efficient in enhancing the scientific literacy of pupils in high school on global warming material at SMAN 1 X Koto Diatas.]]>
