Designing Vocabulary Instruction in ELT: Digital Media, Classroom Practices, and Learner Engagement explores how vocabulary learning can be effectively designed to support meaningful language development in English as a Foreign Language (EFL) contexts. As vocabulary constitutes a fundamental component of language proficiency, its development requires more than memorization; it demands structured, engaging, and contextually grounded instructional practices. This book examines how vocabulary instruction can be enhanced through the integration of digital media, interactive methods, and classroom-based practices. Across different educational levels, the discussions highlight how teachers design learning experiences that promote active engagement, contextual understanding, and sustained vocabulary retention. Rather than treating vocabulary learning as isolated word acquisition, the chapters position it as part of a broader process of meaning-making in language use. A key focus of this book is the role of digital and multimodal resources in supporting vocabulary development. The use of platforms, games, audio-visual materials, and interactive tools demonstrates how technology can create more dynamic and learner-centered environments. These approaches enable learners to encounter vocabulary in meaningful contexts, facilitating deeper processing and more effective retention.
