The TEFL course I did was a 30 hour course on teaching young learners. It was extremely informative and even though I am an experience ESL teacher I have only recently started teaching young learners and this course opened my eyes to the massive difference between teaching adults and children. I learned so much and it instantly made a difference to my teaching methods. What works for adults does not necessarily work for children and there is a lot more psychology behind teaching children. It's very reasonably price, very concise and it's all online - what could be better. Thank you TEFL!
