Along with changing and developing technologies day by day the role of English Language Teaching has been gradually evolving. With the 21st century the nature of learning has also changed depending on society business and our children. Yet it is hard to say recent educational processes are in line with this shift. Although numerous in-service and pre-service teacher training programs are being offered all around the world they generally tend to follow the good-old materials with traditional content. Therefore this book concentrates on "The Catchy Trends" which can meet the needs of the 21st century learners and teachers. 
The scope of our book covers subjects related to foreign language instruction to Gen-Z students Flipped learning Inquiry-based language learning Corpus-based instruction Gamification in language learning Use of technology and Post-method pedagogy in the language classroom. It is a book intended to be not just interesting but useful. We as both the editors and the contributors believe that this book will enable those involved in the teaching of English as a foreign language to increase their awareness while at the same time help their instruction to be more effective and up-to-date. Let's "Catch The Trend".
