互联网对教育的贡献

2008/04/01

……
What about the second big goal (learning)? Heavy technological artillery has been applied to education starting in the 1960s. The basic idea has always been to amplify the efforts of our greatest current teachers, usually by canning and shipping them to new students. The canning mechanism is almost always a video camera. In the 1960s we shipped the resulting cans via closed-circuit television. In the 1970s the Chinese planned to ship their best educational cans all over their nine-million-square-kilometer land via satellite television. In the 1980s we shipped the cans on VHS video tapes. In the 1990s we shipped the cans via streaming Internet media. We’ve been pursuing essentially the same approach for forty years. If it worked you’d expect to have seen dramatic results.

What if, instead of increasing the number of learners per teacher, we increased the number of teachers? There are already plenty of opportunities to learn at your convenience. If it is 3:00 am and you want to learn about quantum mechanics, you need only pull a book from your shelf and turn on the reading light. But what if you want to teach at 3:00 am? Your friends may not appreciate being called up at 0300 and told “Hey, I just learned that the Franck-Hertz Experiment in 1914 confirmed the theory that electrons occupy only discrete, quantized energy states.” What if you could go to a server-based information system and say “show me a listing of all the unanswered questions posted by other users”? You might be willing to answer a few, simply for the satisfaction of helping another person and feeling like an expert. When you got tired, you’d go to bed. Teaching is fun if you don’t have to do it forty hours per week for thirty years.

该段引用文字取自”Software Engineering for Internet Applications“一书的Introduction章节。作者用通俗的语言解释了互联网应用存在的意义,而我引用的文字恰恰在解释互联网如何造福教育领域,值得花些时间读一读。

大意是这样的:大约在半个世纪之前,为了解决教育资源不足(缺乏教师)的问题,随着技术的不断进步,各个国家通过不同手段大批量地分发教育资源(比如录像带、电视信号等),直至20世纪90年代,我们终于可以利用互联网来传播教育资源了。这一看似微小的变化带来了引人注目的影响,利用互联网,每个人都有机会发挥自己的一技之长,我们可以在成为一名学习者的同时贡献自己的专业领域知识,成为教育、帮助别人的老师。这一角色的随意转换使得教育资源缺乏问题迎刃而解。作者最后一句说的好:如果不必(像一名教师那样)每周工作40多个小时并如此持续30几年的话,教育别人就会成为每一位学习者的乐事。

2007/12/31
  • 我在twitter上说过,大意是今年除了高考本身就没留下什么值得记忆的了。
  • 不过在高考后,我迅速找到了自己的组织,相信在今后的一年里它会很快地成长起来。
  • 同时,就在前几天,我给我亲爱的笔记本电脑换了一个操作系统,来到了传说中的fancy world
  • 也就在这几天,我在校内网找到了将近6年没有联系的发小,而且通过他们找到了更多的小学同学,这个世界真美好。
  • 对,我要让这个世界更美好!A ZA A ZA FIGHTING!

回忆:上网,我爱并痛着

2007/12/15

2005年02月21日,我在Donews.net开设了自己人生中第一个Blog。 次日,我写了一篇名为《上网,我爱并痛着》的文章。 转天,它被keso收藏为当日的昨日新闻,害得我兴奋了好久。

三年来改变许多,回头再看当初写下的文字,总有种描绘不出的感觉。但相信自己对互联网本身的理解比当初更深了些。每天我们都处在互联网资讯的浪潮里,对他人的变化、突破、创新感到兴奋,哪怕这与自己没有丝毫利益干系。在这连续的兴奋中,还会不时地对未来产生疑惑:”我身处科技最前沿?”、”别人理解我吗?”、”哦买嘎,我快要跟不上了!”,与此同时,社会上的一些奇特现象与媒体关注的焦点也会让信仰互联网的人接受不了,开始怀疑自己努力的价值,发现这个世界变了,变得让自己不认识了。但如果我们心平气和地向互联网发展的本质望去,就会发现,他的本性并没有变,甚至你会觉得,现在所触摸到的怎么可能是那每天风云变幻让自己忙得晕头转向失去自我因而找不到发展方向的互联网呢。

跳出那个”大盒子”吧,控制住有限的激情,保持自己的节奏,多向事物发展的本质望一望,再比较一番自己的本性,一定会让心情轻松许多,即使有再多的利益干扰,也不会失去从容。
