The rapid expansion of digital technologies and artificial intelligence is transforming how teaching, learning, and knowledge construction take place. This book responds to these developments by examining education through the lens of discourse, highlighting the central role of communication in shaping learning experiences in technology-mediated environments. Bringing together insights from applied linguistics, education, communication studies, and educational technology, the book explores digital communication, online and hybrid learning, AI-mediated interaction, classroom discourse, social media, multimodality, assessment, curriculum design, and ethical challenges in contemporary education. Particular attention is given to the ways artificial intelligence influences knowledge production, feedback, participation, identity, and educational decision-making. By integrating theoretical perspectives with practical implications, the book offers a comprehensive framework for understanding and implementing human-centered digital and AI-enhanced education. It will be of interest to researchers, educators, policymakers, graduate students, and professionals seeking critical and interdisciplinary perspectives on the future of learning in an increasingly digital world.
