This research aims to develop an Electronic Learner Worksheet (E-LKPD) based on Problem-Based Learning (PBL) using Liveworksheet to improve students' mathematical problem-solving abilities. The study employed the ADDIE development model, which consists of five stages: analysis, design, development, implementation, and evaluation. The research subjects were 30 eighth-grade students at UPT SMP Negeri 35 Medan. The results indicated that the E-LKPD was valid, with an average score of 87% from media experts and 95% from material experts. The developed teaching module was also deemed valid, with an average score of 95%. The E-LKPD was considered practical, based on student responses (95%) and teacher responses (93%). Its effectiveness was demonstrated by an increase in learning outcomes from pretest to posttest by 28 points, with an N-Gain score of 0.66 (medium category). Students’ mathematical problem-solving skills also improved, as shown by the increase in the number of students achieving mastery from 13% to 93%, and an increase in the average score from 59 to 87.
