黛安·蒂恩是美国华盛顿州布莱成尔小学的专职教师。她从事一份与众不同的工作:指导学生操作电脑时保持良好的坐姿。目前在美国,专门从事这项工作的人还为数不多。众昕周知,美国是全世界最早提倡技术教育的国家。一直以来,学校在技术设备,包括硬件、软件及师资培训上投入了大量资金,但却忽略了电脑可能给孩子身体带来的一系列伤害及其预防。蒂思认为,教师和家长都注重强调技术对文化发展的重要性,把大部分精力放在指导孩子如何使用电脑上, Diane Tien is a full-time teacher at Bradley Elementary School in Washington State, USA. She is doing a different job: instructing students to maintain a good sitting position while operating a computer. At present in the United States, there are only a few people who specialize in this work. Public Xin know, the United States is the first country in the world to promote technical education. Schools have long invested heavily in technical equipment, including hardware, software and teacher training, but have overlooked the range of injuries that computers can cause to their children and their prevention. Teith believes that both teachers and parents are stressing the importance of technology for cultural development and devoting most of their energy to instructing children on how to use computers.
