<![CDATA[The lack of worksheets capable of enhancing knowledge in mathematics instruction, as well as the insufficient use of technology during the teaching-learning process, motivated this study. The objective of this study is to develop a guided inquiry-based Electronic Student Worksheet (E-LKPD) that is valid, practical, and effective, utilizing LiveWorksheets, to improve the learning outcomes of 10th-grade students at SMAN 1 Tilatang Kamang. This study is a research and development (R&D) project using the ADDIE model. The research subjects were students in class X.E4 at SMAN 1 Tilatang Kamang. Validation sheets, user response questionnaires, and mathematics learning outcome tests were used to determine the validity, practicality, and effectiveness of the developed E-LKPD. The results obtained from the study were as follows: a validity score of 87.99% (highly valid) based on the validators’ results; a practicality score of 88.57% (highly practical) based on the user response questionnaires completed by the students; and an effectiveness score of 77.14% (effective) from the mathematics learning outcome tests completed by the students. These results indicate that the E-LKPD developed can be utilized as a teaching tool to improve students’ learning outcomes in mathematics.]]>
