"Many problems of misunderstandings or problems comes from that children these days don't know what now the good language really is"
As a teacher or as parents you want the best for your child, and when you hear that your child has a bad behaviour you need to do something about it. Now for the example of Lee, he wasn't a bad student but he don't say much in the classroom.
Lee had his "own language" the skateboard language. Lee did not know the why there is in class an other language that he and his friends use on the streets and at home.
Helen Nicholson wanted to help Lee at his language and used the specific terms of skateboard to help Lee understand why it is so important to learn many languages as possible. Learning is a practical word, i mean that if u want to learn you need to do and you need to "immigrate" you in that socicity and make the language at your own.
