To add to the excellent blog from Willy on videos to help you in the classroom as warmers, here’s a video to help you outside the classroom.
If you are training to be an English teacher, perhaps doing the Trinity TESOL Certificate, or even if you are an experienced teacher at the stage of doing DELTA or the Trinity Diploma, then you might find this video on phonology extremely useful.
It’s Adrian Underhill (author of the excellent Sound Foundations) explaining the symbols and the sounds of the phonemic chart and how to teach pronunciation. If you dread the thought of any student asking you a phonemic related question, then this is the video for you. It’s one hour long, but it is invaluable for phonemic chart orientation.
