Should Children Be Allowed to Get Bored?

    Children need time to stand and stare. They should be allowed to get bored to that they can develop their ability to be creative.

    Children are expected by their parents to be reading a textbook all the time. However, research shows that it may hamper the development of their imagination, while boredom can give them opportunities to develop creativity.

    Boredom is often linked with loneliness, but a writer named Meera Syal said boredom had helped here in developing her mind. She told researchers about her childhood. Having few things todo, Syal often talked with her neighbors. She also tried to do things like learning to bake cakes. “But importantly, I Thought and wrote a lot, because I was bored,” Syal said. She kept a diary, filling here time with short stories and poems she made up.

    Grayson Perry, an artist, grew up in a family with little money. He enjoyed himself by making up stories, drawing pictures for his stories and reading many books in the library. Bored but free, he spent hours looking out of the window, watching the changing clouds and seasons. Perry filled up his free time with what he liked. He became creative, because he could think freely.

    Dr. Belton is an expert on the effects of emotions on learning. “Boredom could be an uncomfortable feeling,” she said. “But some young people cannot deal with that boredom creatively. So sometimes they may break a classroom window, or drive a car out for a mad race.”

    Usually, when children have nothing to do, they would turn on the TV, the computer, or the phone. Their time on these things has increased, yet they need to have time to think about their experiences through play or just watching the world around them.

    It is this kind of thinking that can inspire the imagination. On the other hand, the TV or phone may cut short the thinking process. That can be harmful to the development of creativity. “For developing the ability to be creative,” Dr. Belton advised, “perhaps we need to stand and stare, and stay off-line from time to time.”

全国政协委员建议设立“汉字节”

       ①国人的汉字书写问题,引起了全国政协委员的重视。

       ②全国政协委员言恭达指出,数字化时代,很多人对电脑、手机产生依赖症,再加上网络语言表达的不规范性和粗鄙化倾向,导致提笔忘字的“失写症”逐步蔓延。

       ③他认为,当今基础教育重在认字,忽视汉字的美。汉字的教学不应该只是高速,而更应该是高质。他指出,汉字国际传播起步较晚,要从战略高度充分认识汉语的国际推广和传播在建立中国与世界有效的话语系统过程中的积极作用。

       ④因此,他建议,必须在国家层面上重视汉字和汉字文化,设立“汉字节”,并建立汉字文化教育基地,打造中华民族汉字文化的精神堡垒。紧抓“一带一路”倡议发展机遇,加强引导推广。在基础教育阶段,应培养孩子的写方块汉字的习惯和对汉字母语的认同与亲和力,使汉字教学能够从传统文化层面进行。要运用现代传媒手段,全民普及汉字文化,通过电视、广播、新媒体等大众传媒打造“振兴汉字文化”类精品节目,让观众学习汉字知识,领略汉字之美。

       ⑤他还建议,将汉字书写融入社会评价体系之中,“不管是大中小学生,还是各业成人应提倡书写,让书写汉字成为一种生活习惯与方式。”

       ⑥全国政协委员苏士澍呼吁:“学好汉字、写好汉字,已成为关系到中华文化自信、文化传承、民族凝聚力提升甚至国家文化安全的大事,全体国人都应该对此高度重视。我们共同向所有国人发出倡议——‘写好中国字,做好中国人;从自己做起,从现在做起’”。

       ⑦据了解,为推动青少年汉字书写教育,2016年,苏士澍联合其他全国政协委员先后到全国20多个省、上百所学校就“书法进课堂”实施情况进行调研,发现中小学校书法教育资源分布严重不均衡,书法教师严重短缺,开课率严重不足等教学瓶颈和困难。

       ⑧苏士澍说,从现在开始,我们要在日常工作生活中多用汉语,多动笔写字;要投入更大的力量加强书法教师培养,拓展电脑、互联网等现代化教学平台,大力推进“书法进课堂”的汉字书写教育,教导孩子们会写字、规范写字;建议设立“全国汉字书写日”,在全社会积极营造“写好中国字、做好中国人”的社会氛围。
