Glad you found the video interesting @osanka_r David is such a natural! I guess it’s worth mentioning that the class in the recording is an options class that focussed on academic vocabulary through the use of technology (2-3 lessons per week). The students had their core EAP lessons (10 lessons per week) and on top of that they had an afternoon class of their choice. So, perhaps it might be difficult for teachers to spend some much time on vocabulary in a skills class e.g. reading, listening, etc. but the video does offer plenty of ideas you can take and apply to your context.
