<![CDATA[21st-century skills are essential for teachers in integrating rapidly advancing technology into the teaching and learning process. Teachers are required to utilize media, especially digital media, in classroom activities. This study aims to develop a teaching module using digital media for plane figures material based on the PBL (Problem-Based Learning) model for Grade II elementary school and to evaluate the quality of the developed module. The research employed the R&D (Research and Development) model with the ADDIE framework. Four validators participated in the study: one lecturer, one Grade II teacher, one language expert, and one ICT expert. Data collection techniques included a needs analysis questionnaire. Data analysis utilized both qualitative and quantitative approaches. The findings of this study are as follows: (1) The teaching module using digital media for plane figures material was developed through the five stages of ADDIE: Analyze, Design, Development, Implementation, and Evaluation. (2) The validated teaching module achieved a score of 3.75, categorized as "very good," based on several aspects such as cover design, preface, table of contents, module content, and language. (3) The benefits of the teaching module for students, as evidenced by the average post-test results from two sessions, showed an improvement from 86% to 92%, with an average increase of 6%. Therefore, the teaching module using digital media for plane figures material with the PBL model effectively aids students in understanding the topic. ]]>
