"The book explores how the evolving global role of English as a lingua franca (ELF) challenges traditional approaches to English language teaching. Focusing on Polish in-service EFL teachers, it investigates their views and attitudes towards ELF-oriented pedagogy and outlines five key principles that form its foundation. Through a mixed-methods study conducted among English language teachers in Poland, alongside an innovative classroom project with secondaryschool learners, the author highlights both the benefits and challenges of implementing ELFaware practices. Additionally, the book provides practical guidelines and sample activities to support teachers in effectively integrating ELForiented strategies. This work offers valuable insights for teachers and researchers seeking to adapt ELT to todays multilingual and multicultural realities, promoting a more inclusive, flexible, and context-sensitive way of teaching English in the 21st century"-- Provided by publisher.
