The landscape of English Language Teaching (ELT) has evolved significantly over the past 75 years, marked by major shifts in theoretical, technological, and sociocultural approaches to language teaching and learning. From the dominance of behaviorist methods in the mid-20th century to today's innovations in digital, tech-mediated language learning, these transformations have created both opportunities and challenges for teachers. The rapid growth of technology, along with the changing status of English as a global language and the evolving goals of language learning, has further reshaped how languages are taught and learned. Yet, amidst these profound changes, the role of teachers remains central. Teachers are tasked not only with adapting evidence-based methods to address the diverse needs of students but also with fostering meaningful interactions, encouraging critical thinking, and maintaining high levels of student engagement. As ELT continues to advance, teachers are called upon to continually reflect on their practices, adopt new evidence-based approaches, and adjust their teaching methods to meet the evolving needs of their students.
