DEVELOPMENT OF AUDIOVISUAL MEDIA TO IMPROVE JUNIOR HIGH SCHOOL STUDENTS’ ABILITY IN WRITING EXPOSITORY TEXTS

Abstract

This research was initiated due to students’ low proficiency in writing exposition texts, primarily resulting from challenges in understanding text organization, using formal language, and the lack of engaging and interactive learning media. The aim of this study is to create audiovisual learning media to enhance the exposition text writing skills of eighth-grade students at SMP Negeri 8 Percut Sei Tuan. The research applied a Research and Development (R&D) method using the ADDIE model, which consists of five stages: Analysis, Design, Development, Implementation, and Evaluation. Findings from the analysis phase showed that students experience difficulties in grasping the structure and appropriate language use in exposition texts. Validation carried out by experts in material, media, and language demonstrated that the developed media was classified as highly valid, with an average score exceeding 88%. Field testing showed the audiovisual media was considered practical and easy to use, reflected by 92% of students giving positive responses. The effectiveness assessment demonstrated significant improvement in students’ writing ability, with an average pre-test score of 52.73 increasing to 84.58 in the post-test, and an N-Gain value of 0.6657 (66.57%), categorized as effective. The media was proven to enhance student motivation and learning outcomes through engaging and contextual material that integrates visual and audio elements effectively. Therefore, the audiovisual media developed using the ADDIE model is feasible as an innovative learning tool in Indonesian language instruction to strengthen students’ exposition writing skills in an effective and enjoyable manner. The findings suggest that audiovisual-based media can serve as a creative learning alternative to support 21st-century technology-oriented language education.
