Abstract

This study aims to develop flipped classroom-based teaching materials to enhance students' comprehension skills in English Correspondence, a critical course for fostering professional written communication in international business contexts. The research used a Research and Development (R&D) approach, specifically the 4D model (Define, Design, Develop, Disseminate). Expert validation of the materials yielded a high validity score of 86%. A small-group trial yielded an 84% practicality score, indicating the usability of the materials. Effectiveness was measured through a pretest and posttest, revealing a moderate improvement in student comprehension with an N-gain score of 0.54. These findings suggest that the flipped classroom model enhances students' engagement, supports independent learning, and strengthens both theoretical and practical understanding of English business correspondence. The developed materials demonstrate the potential of flipped classrooms in improving comprehension skills and learning outcomes in English Correspondence courses. This research highlights the practical implications of innovative teaching strategies in higher education.

Abstract

This study aimed to develop flipped classroom-based teaching materials for the English Correspondence course to improve students’ comprehension of professional written communication. The research was motivated by the limitations of conventional lecture-centered instruction, which often restricts student engagement and provides insufficient opportunities for independent and practice-oriented learning. A research and Development (R&D) approach employing the 4D model (Define, Design, Develop, Disseminate) was applied to systematically design, validate, and evaluate the instructional product. Data were collected through needs analysis, expert validation, student response questionnaires, and effectiveness testing using a pretest–posttest design. Expert validation results indicated a validity level of 86%, categorized as very valid, while practicality testing showed an 84% score, demonstrating that the materials were accessible and supportive of independent learning. Effectiveness testing revealed a significant improvement in students’ performance, with mean scores increasing from 58.51 (pretest) to 80.54 (posttest) and an N-gain value of 0.54, indicating moderate learning improvement. These findings suggest that flipped classroom-based teaching materials effectively enhance students’ conceptual understanding and practical competence in English business correspondence. The study implies that integrating validated digital instructional materials with student-centered learning models can strengthen technology-supported pedagogy and provide a scalable framework for improving professional communication learning in higher education.
