Abstract

One of the cultural behaviors of local wisdom that is starting to disappear is related to how manage the "garbage". Several communities still throw garbage out of place, such as in the river. On the other hand, the effects of this waste that was disposed of carelessly are very long-term for human health and also the environment. This culture is eventually emulated by their children and grandchildren who are still in school. For this reason, community awareness regarding waste needs to be directed, one of which is the management of a community waste bank. In Tegalsari Village, Ambulu Jember there is one Cipta Mandiri Waste Bank that has been operating for the last 3 years. The Waste Bank activity went quite well, but less than 20% of the community participated, especially young people and children who were less interested. So that the empowerment of the Waste Bank needs to be supported in order to be able to pass down the local culture of being aware of waste, especially for elementary school students through the socialization and education of ethnomathematics worksheets in the elementary school. The results of the activity showed that 78% of students wanted to take part in the waste bank around their homes and they enjoy learning with ethnomathematics worksheets about garbage.

Abstract

Geometric skills was one of the essential competencies in mathematics learning. However, instruction that did not consider differences in students’ abilities could hinder the achievement of this competency. This study aimed to produce a differentiated learning module on quadrilateral material that was valid, practical, and effective in improving students’ geometric skills. The study used the 4-D model, which included the stages of define, design, develop, and disseminate. The research subjects were 24 eighth-grade students at SMP Negeri 1 Rambipuji. Data collection techniques were questionnaire techniques and test techniques, with the included instruments being on validation sheets, teacher and student response questionnaires, pre-test, and post-test. The research results showed that the developed learning module had a validity score average of 3,84, practicality ratings of 97,50% from teachers and 83,02% from students, and an effectiveness score with an average N-Gain of 0,76 (high category). The module included learning objectives, diagnostic assessments, differentiated activities, summative assessments, and reflection. Each student group received scaffolding tailored to their ability level. This learning module could be used to support differentiated instruction aligned with the Merdeka Curriculum.
