1、用电脑录音各位老师：大家好！我是 xx 号考生，我说课的题目的是 用电脑录音 ，下面我准备从说教材、说教学目标、说教法、说学法、说教学过程这几个方面开始我的说课首先说教材 用电脑录音 是陕西科学技术出版社四年级下册第一单元第2课。本课的主要内容是让学生学习电脑录音的方法。是在了解多媒体电脑的基本操作的基础上进行为进一步 用多媒体电脑学习打下坚实的基础。既符合学生的现实需要又有利于学生的长远发展；既贴近生活，又有助于拓展学生的视野，依据义务教育信息技术课程标准我确定了如下的三维目标：知识目标：学会打开录音机以及保存录音作品的方法这也是本课的教学重点能力目标：掌握用电脑录制声音的方法这也是本课的难
2、点情感目标：通过用电脑录音的过程，感受信息技术的乐趣，提高学生的信息素养其次是说教法和学法：根据本节课的教学内容和学生的思维特点，以及新课改提出的理念“学生是学习的主体，教师是组织者、合作者和引导者”因此采用的教法是演示法和任务驱动教学法，四年级的学生正处于具体运算阶段该年龄阶段的学生思维活跃，爱表现，所以采用的学法是自主探究法与小组合作探究法下面呢我来说一说教学过程：首先是导入部分：我会采用谈话导入的方式进行导入，激发学生的热情和学习兴趣，让学生带着好奇心进入到课程来。同学们大家上午好！今天，我们班来了一位客人，它的名字是 Mr computer,我们可别小看它，它的本领大着呢！下面就跟着老
3、师一起来探索电脑先生的本领吧！其次是基本部分：第一个环节：通过自主探究与任务驱动法的有机结合的方式让学生自主去探究打开录音机的方法，教师通过演示法让学生感知录音机的基本操作。最后教师通过问答法总结。刚才大家都熟练地打开了录音机。哪位同学来说一说如何进行录音呢？首先单击录音按钮，开始录音，接着单击停止按钮停止录音。他还发现录音时距离的不能太近，时间不能太长。那要想让录制好的声音不丢失，我们该怎么办？接下里以小组进行探究。第二个环节：我会采用小组竞赛的形式，让不同层次的学生掌握用电脑录音的操作，教师巡回指导，给予学生肯定文档编码:CL4J3N2K2Y7 HG3M4J6V8Z3 ZC3X7M6P10
