<![CDATA[The learning process in higher education requires contextual textbooks that are relevant and able to meaningfully adapt to the characteristics of students. However, at Musamus University, most teaching materials still rely on general textbooks from outside sources, which insufficiently represent the realities of local education in Papua. This research aims to produce a contextual-based Introduction to Education textbook tailored to the needs of Primary School Teacher Education (PGSD) students at Musamus University. The study employed a Research and Development method with a quantitative approach through a quasi-experimental design. The development process encompassed needs analysis, product design, expert validation, limited trials, revision, and large-scale trials. Validation results indicated an average score of 84.5%, categorised as very good, thereby deeming the product suitable for use. Furthermore, the practicality of the limited trial obtained a student response score of 84% and an activity observation score of 90%. Subsequently, the effectiveness results demonstrated an improvement in pre-test–post-test scores by 21.25 points with an effect size of 2.69. The conclusion affirmed that the contextual-based Introduction to Education textbook is feasible and effective for use by PGSD students at Musamus University. Additionally, students evaluated positively the aspects of clarity, design appeal, integration of local content, and usefulness of practice exercises. Therefore, it is recommended that the study programme adopt this textbook into the official curriculum to promote more contextual learning. Moreover, lecturers should receive specific training to optimise the utilisation of the textbook. Finally, further research may extend the application of the textbook to other study programmes in order to achieve more comprehensive results.]]>
