Some American parents might think their children need better education to compete with those in China and other countries. But how much do the parents themselves need to change?

A new book called Battle Hymn of the Tiger Mother by Amy Chua has caused a debate about cultural differences in parenting. In Chinese culture, the tiger represents strength and power. In the book, Ms. Chua writes about how she demanded excellence from her daughters. She said that she had a clear list of what her daughters, Sophia and Louisa, were not permitted to do, such as attending a sleepover, having a play date, watching TV or playing computer games and getting any grade less than an A.

Many people have criticized Amy Chua. Some say her parenting methods were abusive(辱骂的). She even admits that her husband, who is not Chinese, sometimes objected to her parenting style. But she says that it was the way her parents raised her and her three sisters.

Ms. Chua makes fun of her own extreme style of parenting. She says she eased some of the pressure after her younger daughter rebelled and shouted, “I hate my life! I hate you!”

Ms. Chua says she decided to retreat when it seemed like there was a risk that she might lose her daughters. But she also says American parents often have low expectations of their children’s abilities. “One of the biggest differences I see between Western and Chinese parents is that Chinese parents assume strength rather than fragility(脆弱),” she said.

“The beginning of this intense discussion has to do with what it means to be a successful parent and what it means to be a successful child,” said Stacy Debroff, who has written four books about parenting.

Ms. Debroff says Amy Chua’s parenting style is not limited to Chinese families. She says it represents a traditional way of parenting among immigrants(移民) seeking a better future for their children.

But she also sees a risk. When children have no time to be social or to follow their own interests, they might not develop other skills that they need to succeed in life. Stacey Debroff advises parents to develop their own styles of parenting and not just repeat the way they were raised.
