I am applying for a job and I need to deliver a 20 minutes lesson on 'popular culture'. I do think 20 minutes is very short and I am thinking what skill I should concentrate on. My instinct tell me speaking but I think that the group will be very shy towards me. I thought of doing some disection of a Spanish song with an interesting theme such as Bebe's songs have. Or perhaps inspire myself by looking at some old speaking cards and plan an activity around some of those. Any suggestions?
