准备好应用网络教育的明日教师（上）

全球网（www.World Wide Wde)对教育系统的潜在冲击几乎是无限的。然而，如果我们的教师不具备适当的应用网络的知识和技能，实现的冲击会比可能的要小。证据表明，我们的教师需要培训，以便能够有效利用强大的在线资源，培养我们的孩子在数字社会中自我发展的能力。本文的目的在于探讨基于网络的教学对教师教育计划的冲击。     

The development of spoken language in deaf children: explaining the unexplained variance

Using a large existing data base on children with severe and profound deafness, 10 children were identified whose level of spoken laguage was most above and 10 whose level was most below that expected on the basis of their hearing loss, age, and intelligence. A study of their personal characteristics, family background, and educational history identified factors associated with unusually high performance; these includes earlier use of binaural ear-level aids, more highly educated mothers, auditory/verbal or auditory/oral instruction, reliance on spoken language as a method of communication, individualized instruction, integration, and structured teaching by parents. Parents of high performers also reported being highly commited to and focusing family resouces on developing their child's spoken language.     

在生物学教学中手的应用十例

80％以上的学习是通过视觉完成的。虽然听觉是重要的,但对学习过程来说,重要性只占约10％。因此很明显,直观教具演示是教学过程不可缺少的一部分。直观教具不一定是已经做好或买来的,因此可以通过“手”的应用,或许更多的是为了解决困境。我求助于我的双手作为直观教具,说明各种生物学上的概念。通过学生的手势,可以了解他们对概念是否理解。

被埋藏的爱

Where can we go, if we're lost in the air? What can we find, if there' s nothing there? Who can we talk to,if we're surrounded by hate? When can we walk freely up to that Golden Gate? The answer, my friend, is not to go high, Nor to go across. No, the answer,my friend,is buried deep down.     

把南极大陆变成望远镜

自从伽利略使“望远镜”成为家喻户晓的词汇后,纤细的光束已经帮助好奇的人们揭开了关于宇宙的一些谜团。从无线电到可见光到伽马射线,光子给我们带来了一个又一个惊人的发现。     

提心吊胆的华尔街

The war in Iraq, terrorism, rising oil prices-and now the threat of higher interest rates-are all preying on the market. There comes a point in virtually every bull market when     

数学学习性别差异的一项新研究

不向性别之间先天能力的差异是一个使人感情上敏感的问题,然而这种差异确实存在。获取数学最高成就的才能就是这种差异之一。约翰·霍普金斯大学的 C.P.本鲍和 J.C.斯坦利的最新发现有力地显示出这一点。在对一批选拔出的学生进行高智力调查中,他们发现,“十三岁时,不同性别在数学推理能力上存在着很大差异,在成绩突出的人中,这种差异悬殊表现得尤为突出。”资料表明,通过学习才能测验,数学测验,获
