       This study aims to determine the effectiveness of teaching materials in the form of ethnomathematics-based Student Worksheets (Joglo Traditional Houses, Central Java) on polyhedron  materials to improve student learning outcomes for class VIII Islamic Junior High Schools Plus At Tohari Tuntang for the academic year 2021/2022. 

       The population in this study were students of class VIII JHS Islam Plus At Tohari Tuntang. The sample used in this study were 22 students of class VIII Rabi'ah Adawiyyah, with a sampling technique using cluster random sampling. Collecting data using a test description of the pretest and posttest to measure whether there is an increase in learning outcomes. Statistical test analysis using paired sample t-test with a significance level of 5%. 

The results of the data acquisition were analysed using IBM SPSS Statistics 26. The results of the normality test of the data on the Shapiro-Wilk test showed that the pretest and posttest were normally distributed with the results of the pretest (0.175) > the significance value (0.05) and posttest (0.108) > the significance value (0,05). Then, for the correlation of 0.540 with a significance value of 0.010, because the significance value (0.010) > probability (0.05) so can be concluded that there is no relationship between pretest and posttest. Based on the analysis of the results of the pretest and posttest, the average learning outcomes increased by 41.136%, from 35.68 to 76.82. Thus, the ethnomathematics-based LKPD used in this study is said to be effective in improving student learning outcomes.
