John Woo“BOUNCE high, bounce low, bounce the ball to Guangzhou,” Mark Williams sang while bouncing a ball.He rolled the ball to one of the children seated around him. The child bounced the ball and repeated the song before he passed the ball back to Williams, who sang the song again and gave the ball to another child. This was a scene of the “teaching English through singing” class taught by the American. He is teaching two groups of children.Williams’ daughter was a retarded child because the connection between the right and left sides of her brain did not function. She learned music and singing in a special school and miraculously recovered.“Without music, my daughter would never have graduated from college,” said Williams, adding that this was why he had been so passionate about teaching music and sharing the idea of its healing effect. Williams said people could pronounce English words well when singing. Without music, they would have trouble doing it. Singing uses the brain’s right hemisphere so he is helping children to use both sides of the brain to learn English. Williams is teaching in Shenzhen for the summer vacation. The finale of his program will be a musical, The Amazing Encounter, to be performed by the children. It tells the story of extraterrestrial beings who are fascinated by children’s singing and want to learn from them.
