<![CDATA[The mathematical problem-solving ability of Indonesian junior high school students remains relatively low. This study aimed to develop a Liveworksheet-assisted Electronic Student Worksheet (E-LKPD) based on the Realistic Mathematics Education approach for statistics learning to improve junior high school students' mathematical problem-solving ability. The development model employed was ADDIE. The E-LKPD was designed following the RME learning syntax, namely contextual problems, modeling, discussion and sharing, mathematization, and reflection. A limited trial was conducted with 9 students, followed by a large-scale trial involving 43 students from one class. The results showed that the developed media had been designed in accordance with the stages of the ADDIE model. The developed E-LKPD achieved a very valid and very practical category based on the validation and practicality assessments. Furthermore, the product was found to be highly effective in improving students' mathematical problem-solving ability. Therefore, the Liveworksheet-assisted E-LKPD based on the RME approach is considered valid, practical, and effective as an alternative digital teaching material that supports the implementation of the Merdeka Curriculum and the development of 21st-century skills.]]>
