Abstract: This research was motivated by the low thinking level of SMK Mega Link Majene students in solving higher-order thinking problems and inadequate math teachers using mathematics applications in the learning process. This study aims to develop student worksheets assisted by the GeoGebra application to develop higher-order thinking skills. This research is Research and Development (RnD) using the ADDIE model (Analyze, Design, Development, Implementation, and Evaluation). The participants were 27 eleventh-grade students of SMK Mega Link Majene. The instruments were tests, student activity observation sheets, teacher implementation sheets, and questionnaires. The student worksheets should meet the characteristic of helping students develop higher-order thinking skills–analyzing, evaluating, and creating. The results showed that the student worksheets were in the valid category. The worksheets also fulfilled the practicality category: the learning implementation was well-executed, and met the effectiveness categories: (1) the students' high-level thinking ability in mathematics on average was in the high category; (2) student activity was in the very active category; and (3) student responses to the student worksheets assisted by the GeoGebra application obtained a very positive response. The findings implied that the development of student worksheets assisted by the GeoGebra application met the valid, practical, and effective criteria.
