本书是在原江西省小学信息技术教材的基础上，进一步进行修订。本次修订是在《中小学信息技术课程指导纲要（试行）》的指导下，结合计算机技术的发展，以及信息技术教育教学的最新理念，发扬原教材中的优点，改进原教材中繁难偏旧的内容。小学信息技术教材从小学三年级开始使用，每学期1册，共8册。每册书有3个单元，每个单元围绕一定主题开展多项活动，在知识与活动中，注重对信息技术思想文化的渗透，在潜移默化中培养学生的信息素养。

致 同 学 们 亲爱的同学们，当你们步入多媒体教室时，电脑屏幕将给你们呈现一个五彩缤纷的世界。你们将徜徉在信息技术的快乐天地中：用电脑中的画笔涂抹心中的画；让打印机“吐”出排好版的文章、课程表、电子报刊；紧跟时代的步伐，制作出好玩有趣的动画；在因特网上冲浪，汲取知识的浪花，与同学分享成功的喜悦；制作多媒体作品，展现实力不凡的自我。 本套教材共8册，从小学3年级开始使用，每学期1册。同学们翻开课本，就会发现每册书一般有3个单元，每个单元让同学们围绕一个主题开展多项活动，每节课完成一个活动。在完成这些实践活动后，同学们就会掌握相关的软件知识，提高计算机操作技能。不同技术要求的实践活动，将引领同学们摘到属于自己的那颗“果子”。 为了帮助同学们学习，教材设计了“跟着做” 、“试一试” 、“知识窗” 、“评一评” 和“阅览室” 等一系列栏目。 是对全体同学的基本要求，培养同学们的操作技能，同学们在老师指导下或阅读教材后都能完成； 给不同学习能力的同学，留下不同层次的练习，让每个同学都有所收获； 介绍“跟着做”中涉及的基本概念和理论知识，帮助同学们加深对知识的理解和扩展； 让同学们对学习情况进行自我评价，激励自己不断进步； 提供了与教学内容相关的课外阅读资料，丰富信息技术学科的学习内容，可以拓宽同学们的知识面。 同学们，只要你们用心学习，就会发现，信息技术会给你们带来许多学习乐趣和创作动力。推开信息技术的大门，进入崭新的信息时代吧！ 本套教材的服务网站为http://www.hxedu.com.cn。书中涉及的图片、软件素材，请到本站“资源下载”栏目下载。 服务信箱为hxedu@phei.com.cn。 编　　者
