It isn’t easy to get people to break bad habits. Think how hard dieting is or stopping smoking. Same with using a textbook to learn or teach English, to learn or teach any language. Language is alive and should be taught through something that speaks, that sounds, that says, that lives and has color and moving images. In a word, video.
This fun video, part of a Hitler Reacts remix, highlights makes this point very well. Enjoy, laugh and take a break from your day job!
