提纲：

P1：

作为21世纪最重要的发明，计算机已经在一些生活领域普及并成为必须，但在教育界却不竟然。

尽管计算机辅助教育广泛应用，教师在课堂上仍然不可少。

P2：

虽然一些学科计算机可以成功地运用于教学。

例如：

基础数学，基础语言学习，任何一种需要学生通过重复来记忆的领域都非常适合计算机教学。

通过程序，计算机可以毫不厌倦地提供各种问题给学生，通过这种方式强化知识；

P3：

但是，一些复杂的理论（complexideas）不能被计算机传授。

计算机可以判断（determine）哪个答案是对错，但不能告诉学生错在哪里，也不能以另外一种方式解释这个定义。

Tasksinvolvingreasoningcannotbetaughtbycomputer.在处理这些问题上，教师必不可少。

P4：

而且，计算机不能成功地组织一些基本的学习交流，如：

讨论（discussion）,联想（association）,比喻（imagery）都是课堂上常用的教学方式，教师可以通过这些方式excitestudent’simaginationandfiretheircreation.However,itistoocomplexforacomputertodealwith.

P5:

总的来说，计算机，特别是多媒体信息技术（multimediatechnology）给教育界带来许多重要的革命，但老师仍然是课堂的主人。

我们应该记住，人类永远是科学技术的主人，无论计算机有多聪明，它只不过是一个电子机器而已。
