Developing English Reading Materials for Tenth Grade Students of Software Engineering in Vocational High School

This study aims to develop English reading materials tailored for tenth-grade students in the Software Engineering program at SMKN 1 Semparuk, addressing the lack of discipline-specific content in existing textbooks. Employing a Research and Development (R&D) design with a modified ADDIE model, the study focused on the stages of Analysis, Design, and Development. Data were collected through needs analysis involving students, teachers, curriculum documents, and textbooks, combined with expert validation using structured evaluation instruments. The resulting materials, consisting of descriptive and procedural texts enriched with software engineering vocabulary, were evaluated by two experts and achieved an average score of 3.45, which falls into the “Very Good†category. Teacher and student feedback further confirmed the practicality, relevance, and effectiveness of the materials in enhancing reading comprehension, motivation, and confidence in dealing with technical texts. The findings highlight the importance of integrating English for Specific Purposes (ESP) principles into vocational education, ensuring alignment between language learning and professional needs. This research contributes both theoretically and practically to ESP materials development, offering a replicable model for designing context-specific English resources in vocational high schools.
