Abstract

Learning mathematics in elementary schools, particularly regarding fraction subtraction, is a challenge for both teachers and students. The purpose of this study was to describe students' EDP (Engineering Design Process) activities through the Implementation of Student Worksheets (LKPD) based on Indonesian Realistic Mathematics Education (PMRI) and the STEM (Science, Technology, Engineering, and Mathematics) approach, with the support of Artificial Intelligence (AI) on the concept of reducing fractions in elementary schools. The subjects in this study were fifth-grade students of SD Negeri 158 Palembang. The observation technique of document study of students' EDP activities in the implementation of LKPD based on PMRI and the STEM approach, with the support of AI, was categorised as good. It is recommended that the development of STEM-based Student Worksheets (LKPD) be continuously improved by taking into account the characteristics of students and the context of everyday life, so that the material on reducing fractions can be understood in a meaningful way.
