Abstract
This study aimed to develop an ethnomathematics-based E-LKPD assisted by Google Sites on probability material for eighth-grade junior high school students that is valid and practical for learning. This research used the Research and Development (R&D) method with the Four-D (4D) development model, limited to the first three stages: define, design, and develop. The study was conducted at SMPIT Mutiara Insan Cepu, involving material experts, media experts, mathematics teachers, and eighth-grade students as research subjects. Data collection techniques included interviews, observations, and questionnaires. The research instruments consisted of expert validation sheets and student response questionnaires. Data were analyzed using quantitative and qualitative descriptive techniques. The results showed that the ethnomathematics-based E-LKPD assisted by Google Sites obtained a media expert validation score of 91.67% and a material expert validation score of 91.67%, both categorized as very valid. In addition, student responses obtained an average percentage of 91.67% categorized as very practical. Therefore, the ethnomathematics-based E-LKPD assisted by Google Sites is feasible to be used as teaching material on probability for eighth-grade junior high school students.
