This book examines the phenomenon of English Medium Instruction (EMI) in Turkish higher education, using research-based findings and review-based discussions with a critical focus on diverse aspects of EMI. Particularly, it addresses issues under four major themes: EMI policy and the macro level context, teaching practices in EMI, learning experiences in EMI and future directions for EMI in Turkey. English as the Medium of Instruction in Turkish Higher Education: Policy, Practice in Action and Future Directions comprehensively examines the EMI phenomenon by taking Turkey as a case study and it exclusively explores existing issues against different conceptual frameworks and theoretical foundations. It also explores novel issues around EMI, such as EMI assessment, EMI classroom interaction, and technology-enhanced EMI teacher training. Written by established experts in the field, this volume will be of particular interest to scholars of English for Academic Purposes, English Medium Instruction and Applied Linguistics as well as postgraduate students of Applied Linguistics, English as a Lingua Franca, English for Academic Purposes, and language and education policy. The book might also appeal to policy makers both in Turkey and in international education seeking blueprints to align their avowed principles and ground realities for purposes of effective practices.
