There is simply no way to rest on our past achievements. Today’ s competition renders obsolete huge chunks of what we know and forces us to innovate. For each individual, several careers will be customary, and continuing education and retraining will be inescapable. To attain this extraordinary level of education, government, business, schools and even individuals will turn to technology for the answer.
In industry, processing the information and designing the changes necessary to keep up with the market has meant the growing use of computers. The schools are now following close behind.
Already some colleges in the United States are requiring a computer for each student. It is estimated that 500, 000 computers are already in use in American high schools and elementary schools. Although there is an abysmal lack of educational software, the number of computers in schools expands rapidly.
The computer is the Proteus of machines, as it takes on a thousand forms and serves a thousand functions. But its truly revolutionary character can be seen in its interactive potential. With advanced computers, learning can be individualized and self-paced. Teachers can become more productive and the entire learning environment enriched.
It is striking how much current teaching is a product of pencil and paper technology. With the computer’ s capacity for simulation and diverse kinds of feedback, all sorts of new possibilities open up for the redesign of curriculums. Seymour Papert, the inventor of the computer language LOGO, believes that concepts in physics and advanced mathematics can be taught in the early grades with the use of computers. He cites as an example the teaching of the laws of motion in physics, which he says are accessible at an early age when a computer is used to assist in the instruction.
On an everyday level, word-processing significantly improves the capacity for written expression. How? Simply by making it easier to revise and rewrite. In terms of drill and practice, self-paced computer-assisted instruction enables the student to advance rapidly—without being limited by the conflicting needs of the entire class.

答案
我们决不能够吃老本。当今的竞争使得我们大部分知识变得陈旧,非加以革新不可。在未来,每个人都会对从事好几种职业习以为常,并将继续进修,重新接受培训,这是不可避免的。为了达到这种非同一般的教育水平,政府、工商业部门、学校甚至个人都将求助于技术来解决问题。 在工业领域,必须处理信息,制定必要的改革计划,来适应市场的需要。这意味着对计算机的使用会越来越多。学校现已紧随工业部门之后。美国已有一些学院要求每个学生都有一台计算机。据估计,美国中小学使用的计算机已达到五十万台。虽然教学软件十分紧缺,学校的计算机数量却迅速增加。 计算机是一种变化多端、神通广大的机器,它可以显示一千种图像,发挥一千种功能。但它真正革命的特性能够在人机相互影响的潜力方面表现出来。有了先进的计算机,学习就可以单独进行,速度可以自行规定。教学会变得更有成效,整个学习环境会显得丰富多彩。 令人吃惊的是,当前的教学在很大程度上还是铅笔和纸张技术的产物。计算机能够实行模拟并提供各种反馈,为重新设计学校的课程提供了各种前所未有的机会。计算机语言(标识语)的发明家西摩?佩伯特认为,利用计算机,在低年级就能教授物理学和高等数学的概念。他援引教授物理学的一些运动定律为例,说明计算机用于辅助教学时,学生在幼年就能够理解这些定律。 在日常生活中,文字处理能相当有效地提高书面表达能力。如何提高呢?只要让文字更便于修改和重写就可以了。从训练和练习来说,使用自行规定速度的计算机辅助教学可以使学习突飞猛进,而且不受全班学生各有不同需要的限制。
