Development of Student Worksheets for Matrix Topic in Senior High School Mathematics

Abstract

Despite the growing body of student worksheet development research in mathematics, few studies have integrated real-life economic contexts, particularly the Sustainable Development Goals (SDGs), into matrix learning materials. This study aims to develop and validate an SDG 8-integrated Student Worksheet for matrix learning in grade XI at SMAN 2 Ponorogo and MA Darul Huda Mayak. The method employed is a modified version of Thiagarajan’s 4D development model, limited to three stages: define, design, and develop. Two mathematics teachers served as validators, assessing the student worksheet using a content validity questionnaire analyzed with the Gregory formula. The validation results yielded a content validity coefficient of Vc = 1.00, indicating very high validity based on Gregory’s criteria (0.80–1.00). The student worksheet is designed to help students understand matrix operations and apply them in real economic contexts relevant to SDG 8 (decent work and economic growth), making it potentially suitable for supporting contextual matrix learning in senior high school.
