This study is based on preliminary studies that identified the problem of suboptimal learning quality. The objective of the study is to develop a digital e-module within the teaching factory (TEFA) (TEFA)-T learning model as an effort to improve the academic achievements of automotive vocational students, ensuring the module is valid, practical, and effective. The study method is research and development (R&D) using the Instructional Development Institute (IDI) model development procedure, which consists of three stages: define, develop, and evaluate. The results of this study generally produce a comprehensive digital learning e-module design consisting of a cover, preface, table of contents, learning structure, learning patterns, e-module position map in learning, glossary, learning introduction, learning activities, evaluation, and closing. The TEFA-T learning e-module is statistically validated and practical. The average Aiken’s V value obtained is 0.967, indicating that the digital e-module content is in the valid category. The TEFA-T learning e-module is considered very practical, as shown by the average practicality assessment scores of 92.20% from lecturers and 90.60% from students, both in the “Very Practical” category. In conclusion, after implementing the TEFA-T learning e-module, students can build knowledge inductively and deductively, as well as gain learning experiences through one-way interaction, personal interaction, and effective learning interaction, significantly improving student academic achievement (Sig. 2-tailed value is less than 0.05). © 2025 by the authors of this article.
