<![CDATA[This study, entitled The Development of a Problem-Based Learning-Based Teaching Module on the Application of Pancasila Principles to Improve the Communication Skills of Fourth-Grade Elementary School Students, was motivated by the low communication skills of elementary school students and the unavailability of teaching modules specifically designed to develop these skills through meaningful learning. This study aimed to describe the process of developing a Problem-Based Learning (PBL)-based teaching module to improve the communication skills of fourth-grade elementary school students.This research employed a Research and Development (RD) method using the ADDIE development model, which consists of the stages of analyze, design, develop, implement, and evaluate. The research subjects were 20 fourth-grade students of SD Kanisius Kalasan. Data were collected through observation, interviews, questionnaires, and document analysis. The developed teaching module was validated by four experts, consisting of two subject-matter experts and two instructional experts. The validation results showed that the teaching module obtained an average score of 3.56, categorized as very valid in terms of module readability, structural feasibility, integration of the PBL model, and integration of communication skills. The findings indicate that the developed PBL-based teaching module is feasible to be used as instructional material to support the improvement of communication skills of fourth-grade elementary school students.ABSTRAKPenelitian berjudul Pengembangan Modul Ajar Penerapan Sila-Sila Pancasila berbasis Problem Based Learning untuk Meningkatkan Keterampilan Komunikasi Siswa Kelas IV SD yang dilatarbelakangi oleh rendahnya keterampilan komunikasi siswa sekolah dasar serta belum tersedianya modul ajar yang secara khusus dirancang untuk mengembangkan keterampilan tersebut melalui pembelajaran yang bermakna.
