This research was motivated by the low writing skills of procedural texts of grade IV students of Pamulihan Elementary School, Pamulihan District, Sumedang Regency in the 2024/2025 Academic Year. Students' skills in writing procedural texts are still not optimal in terms of structure, namely; the suitability of the title to the content, the choice of diction so that the same words are repeated. This is because vocabulary and language mastery are still minimal and limited stimulation of imagination is caused by less varied learning, resulting in a lack of skills in stringing words together. The purpose of this study was to determine the effect of diorama media on procedural text writing skills. This type of research is quantitative research using the Pre-Experimental method with the One-Group Pretest-Posttest Design. The population taken was all 18 fourth-grade students of SDN Pamulihan with a saturated sampling technique. The data collection technique used in this study was a test technique.
