Abstract

This research aims to produce worksheet products for students on Ethnomathematics-based two-dimensional figures in class VII that are valid, practical, and effective. This research uses the development of the 4D. the subject of this research 7 grade of Kelimutu Private Junior High School. Analysis of the validation value of student worksheets from media experts obtained 93% and material experts 85%, which is a very valid category, so it can be tested. The questionnaire classification of student responses results in the good practicality category with 81% showing that the student worksheet dimensional figure is practical. Effectiveness is obtained from the completeness of student's classical learning outcomes after using an ethnomathematics-based student worksheet which is very effective at 90% (Students who get a score > 60) with the criteria for learning completeness being in the very good category. The use of ethnomathematics-based student worksheets is very effective in learning. The result of the N gain calculation obtained an average of 0.56 in the medium category, so using ethnomathematics-based student worksheets was effective.
