The poor mathematics communication abilities of eighth-grade students serve as the driving force behind this study. This study's goal is to use E-LKPD, which is based on contextual learning, to evaluate and characterize students' mathematical communication abilities. Design research using the Ploom and Gravemeijer development model is the methodology employed. Test questions for students' mathematical communication abilities, practicality assessments, and expert validation serve as the research tools. Students in grade VIII.8 at SMP Negeri 26 Padang during the 2024–2025 school year served as the study's subjects. The pupils' test scores for mathematical communication skills are as follows: the proportion of pupils that are proficient in mathematical communication on indications (1) Expressing mathematical ideas verbally, in writing and by visualizing them is 81.7; (2) Interpret and evaluate mathematical ideas both orally, in writing and in other visual forms is 76.6; (3) Using mathematical terms, symbols, and structures to model mathematical situations or problems a 66.7 percentile. With a good category, the average is 73.8 overall. This indicates that students' mathematics communication skills can be effectively improved by CTL-based E-LKPD. © 2026 Author(s).
