简介: 从一间房到另一间房,从单位到家里,我就这样被生活囚禁.看到的总是那样狭窄的一片天空,日子过得越来越无聊.除了重复还是重复,除了压抑还是压抑.我越来越感觉要窒息.……

简介:一天,记者姐姐在网上逛啊逛,忽然发现了一个特别有意思的地方——怪老头儿随想录(http://adp.6to23.com/hongnini/guailaotou/index.htm),这不是著名儿童文学家孙幼军爷爷的个人网站吗?小时候我最喜欢看他的童话《小布头奇遇记》、《小猪唏哩呼噜》了。打开网站主页
简介:E-learning目前已经成为一个流行术语,在google搜索引擎上,和E-learning相关的网站达到了180万个,这几乎是任何一个专业研究者穷其一生都无法阅读完的数字.越来越多的教育机构和培训机构,把E-learning作为自己的宗旨和目标,甚至许多企业也把E-learning作为自己员工培训的重要手段.但是要给E-learning下一个准确的定义,仍不是一件容易的事.有人解释为电子学习,有人解释为在线学习,有人解释为远程教育,可谓众说纷纭.也许这种对E-learning理解的多样性,恰恰说明了E-learning的包容性和无限广阔的发展前景.
