Bi Yansong, a famous TV host, expressed his support for students wearing green scarves (绿领巾) at a primary school in Xi’an. He wore a green tie on a TV program on October 19, 2011.
“I just want the students to know that I’m also wearing green. And we are all great people and are as good as those wearing red scarves.”
The First Experimental Primary School in Xi’an made children with poor schoolwork and behaviors wear green scarves. Parents whose children wore green scarves were angry. “The punishment is too bad. All the children need their self-esteem(自尊心) even though they are very young, and they know the green scarf means something is not quite right. It does harm to students’ self-esteem,” said one mother. Educational expert Li Zhenxi said that primary and junior high school students have strong self-esteem. they hope to be respected(尊重) and understood. Punishment will hurt them. “It’s better to encourage them rather than call them ‘bad’ students,” he said. Now, the school has stopped the practice.
Some schools think more of students’ self-esteem and have done better in protecting students’ privacy (隐私) and encouraging them. In American schools, teachers post test results on the wall. Instead of using students’ names, they use secret numbers. This way, students know their secret numbers and can check their own grades only. Many teachers in China tell students their grades by sending text messages to their students.
School and teachers are doing more for students’ self-teem. But it is a long way. Both teachers and parents should realize that tests scores are not the only measure(标准) of a student’s ability. Everyone has his own strengths and everyone can make great progress by working hard. Adults should make students get to know their own value. The most important is to make students believe in themselves.
