Abstract
The Student Worksheet is one of the essential teaching materials in learning. The Student Worksheet will make it easier for educators to facilitate students in building and developing concepts, attitudes, and skills. However, so far, educators have only used Student Worksheets in the textbook without any development. Ideally, educators should analyze Student Worksheets to develop so that Student Worksheets fit the needs of students. This development research aims to produce Student Worksheets Based on Discovery Learning to improve students^ understanding of the concept of Environmental Pollution at 7th-grade junior high school. This study uses the Design and Development (DnD) method with a 4D development model (Four D Model) from Thiagarajan, Dorothy S. Semmel, and Melvyn I. Semmel, which has four stages: Definition, Design, and Development. Develop), and Disseminate. However, this research only reached the Development stage (Develop) because of the situation and conditions that did not allow for the Disseminate stage. Validation was carried out by two experts, namely material experts and media or design experts. The results of material validation and media validation obtained an assessment in the appropriate category. So that the Student Worksheet is declared feasible and ready to be used as teaching material.
