This research was conducted to design and test digital teaching materials for the Editing Skills course using the 3D Pageflip Professional application, intended as a self-learning tool for Indonesian Language and Literature Education students at Medan State University. Product development was carried out using the 4D model approach (Define, Design, Develop, Disseminate), which includes needs analysis, initial design, expert validation, limited implementation, and dissemination stages. Research data were collected through needs questionnaires, validation sheets, and student perceptions, then analyzed using a combination of percentage-based quantitative techniques and qualitative interpretation. The research sample was determined using purposive and expert sampling techniques, involving 20 students who were or had taken the Editing Skills course, 3 lecturers, and 3 manuscript editing practitioners. The findings indicated that students demonstrated strong enthusiasm for the use of multimedia-based digital teaching materials, which was supported by the availability of adequate technological devices. Validation by material, language, and media experts resulted in an average score of 86.10% (very appropriate), while the effectiveness test through the perceptions of 90 students obtained an average score of 88.77%, with the highest scores in the aspects of media influence (90.52%) and media presentation (90.20%). These results indicated that interactive teaching materials can increase student motivation, engagement, and learning independence. The novelty of this research lies in the application of 3D Pageflip media in the context of language learning in higher education, particularly in editing skills courses that have different characteristics from the exact sciences. In addition, the resulting product is not only a digital teaching material, but also includes a meeting-based instructional design that integrates text analysis activities, editing practices, radio drama production, and mini-field research. Thus, this research confirms that the editing skills teaching material assisted by 3D Pageflip media is valid, practical, and effective, and provides a new contribution to the development of digital learning innovation in higher education in the 21st century.
