Who will my tutors be?
At Dublin TEFL, we want to ensure that teachers on our Dip TESOL get a broad range of expert input from leaders in respective fields of language teaching, learning and education.
Your course will be overseen by the course directors and tutors, Emma and Shaun, who will stay with you for the entire duration of the course. In this way we make sure that you won’t get lost in a long list of course participants. We pride ourselves on getting to know you individually so that we can respond to your unique contextual challenges, build on your knowledge and capitalise on your interests.
At the same time, we also invite guest speakers from a variety of different fields related to the teaching and learning of English to give guest seminars to our teacher cohorts. These speakers have been carefully selected to represent key areas of relevance in modern language teaching. They are experts in their fields and we’re proud they’ve agreed to come on board with Dublin TEFL to provide you with a developmental experience of the highest quality.
Here are some of the guest experts we have had leading interactive seminars on our Dip TESOL courses:
