Globalization has had the greatest impact on business and trade, but it is also having an increasingly significant impact on education. Because of this, some researchers have urged for a revision of the role of teachers in order for them to better model what it means to be a responsible global citizen. In this work, I recognise the necessity for ESL/EFL teachers to re-examine their identities and duties in light of the worldwide developments that have occurred recently. At the same time, I believe that instructors should not lose sight of the necessity of polishing the craft of teaching English in order to develop their professional capital, which will allow them to better moderate the influence of globalization on their students' learning. It is the purpose of this essay to first analyze the shifting roles of teachers in a globalized world and then to discuss the ramifications of this for the teaching and learning of English language. Moreover, the notions are connected to the teaching of second language oracy (speaking and listening), which is critical in the development of essential 21st Century skills in a globalized environment. The essay also discusses ways in which teacher education that is cognizant of globalization dynamics might help ESL/EFL teachers build the knowledge and beliefs they need to be more effective in their new responsibilities as global citizens.
