第三课《窗口探奥秘》信息技术

1、第三课窗口探奥秘-信息技术第三课窗口探奥秘年级：四年级教材：大连市教育局基础教育课程教材发展中心 编 现代教育出版社出版 小学信息技术第一册 第一单元启动计算机之旅 第三课窗口探奥秘第一课时设计者： 西岗区香二小学 周鸿宏一、教学目的：了解窗口，掌握窗口的基本操作。二、教学内容：窗口介绍和窗口操作。三、教学重、难点：1、重点：窗口的基础知识2、难点：窗口的基本操作四、教学准备： 1、计算机、网络及辅助教学软件。2、自制的powerpoint教学软件五、教学过程：（一）复习导入同学们，上节课，老师和大家一起探寻系统桌面各个组成部分的秘密，你们还记得吗？谁能来说一说？（二）新授同学们对系统桌面各个

2、组成部分都有所了解了，那么你们想不想继续探寻计算机窗口的奥秘呢？这节课老师就和大家一起来探寻计算机窗口的奥秘。出示课题：第三课 窗口探奥秘1、窗口的组成我们知道，在windows环境下的所有应用程序都是在窗口中执行的，关闭窗口，也就关闭了程序。下面我们就来一起认识一个最常见到的窗口，它具有indows窗口的许多共同特点。出示图片，教师提问：这就是我们最常见到的窗口“我的电脑” 窗口，你可知道该窗口各部分的名称吗？谁来试一试？（一名学生介绍时，其余学生边看演示边记忆，也可适当加以补充。教师根据学生的回答给予肯定或纠正。）标题栏菜单栏工具栏地址栏窗口控制按钮垂直滚动条状态栏2、窗口的基本操作同学们

3、都知道了窗口各部分的名称，下面我们就来一起探寻窗口都有哪些基本操作。（1）窗口控制按钮还原最小化关闭最大化我们先来看看刚才讲过的窗口右上角的窗口控制按钮，出示图片，指名说一说各部分名称。l 最小化窗口我们先来看最小化按钮的作用（指名示范操作）。让学生自己练习一下，同时找学生做给其它学生看。 l 最大化（还原）窗口让学生自己试，然后总结得出：单击“最大化”按钮 ，窗口会扩大到整个屏幕，此时“最大化”按钮变成了“还原”按钮 ；单击“还原”按钮，窗口恢复原状。l 关闭窗口有没有同学知道怎么关闭窗口（生答单击“关闭”按钮，窗口关闭。）（2）改变窗口的大小下面请同学们观察老师的鼠标指针的形况是什么样子的

4、（）。对，当指针成这种形状的时候我们只要向左右拖动就可以改变窗口的宽度。那么我们又怎么来改变窗口的高度呢？下面老师想请同学来完成这个任务。（请同学来操作）。师把鼠标的指针形状变为，提问：有谁知道老师现在这种指针能改变窗口的什么大小（生答，师总结，能同时改变高度和宽度。）（3）移动窗口师作讲解：指针指向“我的电脑”窗口标题栏，进行拖动操作，可以移动窗口。学生自己练习一下。 （4）浏览窗口全貌打开一个窗口我们想浏览到窗口的全貌时，应该怎么做呢？让学生试一试，再指名演示，最后让学生自己练习以下。3、小结：通过学习，你了解了窗口的作用了吗？有哪些经验要和大家分享？你的操作有没有提高啊？让学生先在小组内

5、说一说，然后每组请一个代表说一说。（三）挑战自己请你分别打开“我的电脑”和“网上邻居”窗口，按书上第16页图3-4所示的式样摆好。（四）全课总结这节课同学们学习了有关windows98的知识。下面老师想请哪位同学来说一说，你这节课学习到的具体内容有那些。能熟练操作吗？教学反思：课堂上，学生唱主角，我则沉入学生中间，互相讨论，平等对话，一起探究。我一方面勉励学生面对失败不气馁，冷静地理清思路后再尝试，培养、优化学生的意志品质和思维品质，另一方面了解学生学习过程中遇到的问题，在必要时给予帮助，针对性地请“成功”的学生上来演示，鼓励“能者为师”，激发学生的好胜心和不服输的精神。学生学习兴致盎然。 我

6、认为，现代教育改革的核心是使学生变被动型学习为主动型学习，让他们在真实的环境中学习并接受挑战性的学习任务。教师的角色逐渐由传统的“知识传授者”转变成“设计者、指导者、组织者、帮助者、学习资源管理者及研究者”。这在给教师提出全新的挑战的同时，也为教师提供了广阔的创造空间。qcwa3ptgz7r4i30ka1dkaghn3xtkknbycudxqa7fhyi2chhi92tgkqcwa3ptgshls50clmtwn60eo8wgqv7xav2ohum32wgeauwydiawgmer4i30ka1dkaghn3xtkknbycudxqa7fhyi2chhi92tgkqcwa3ptgz7r4i30
