Pengembangan Modul Ajar Berbasis Problem Based Learning Konten Sistem Persamaan Dan Pertidaksamaan Linear Untuk Memfasilitasi Kemampuan Representasi Matematis Peserta Didik Kelas X Sma Fase E
This research aims to develop a Problem-Based Learning (PBL) teaching module to facilitate students' mathematical representation abilities (KRM) in the context of linear equations and inequalities systems. Employing a Research and Development (R&D) approach, the module was created using the 4D model, encompassing the stages of define, design, develop, and disseminate. The define phase identified challenges in teaching mathematical representation and the need for a student-centered learning model. In the design phase, initial module drafts and validation tools were developed. The module was validated by experts, with an average score of 86% categorized as highly valid. Practicality tests, conducted in small groups and field trials, yielded average scores of 89% for practicality. Results indicated that the PBL module effectively supports students' engagement and mathematical representation skills by integrating contextual problems into
learning activities.
