ppt的用法在课堂越来越流行英语作文With the advancement of technology, PowerPoint presentations have become increasingly popular in classrooms. This tool offers numerous benefits for both teachers and students, enhancing the learning experience and promoting effective communication. In this article, we will explore the usage of PowerPoint in the classroom and its impact on education.Firstly, PowerPoint presentations provide an engaging and interactive platform for teachers to deliver their lessons. With the ability to incorporate multimedia elements such as images, videos, and audio, teachers can create visually appealing and dynamic presentations. This not only captures students' attention but also facilitates better understanding and retention of the subject matter. Moreover, PowerPoint allows teachers to organize information in a structured manner, making it easier for students to follow the lesson flow.Furthermore, PowerPoint presentations encourage active participation and collaboration among students. Teachers can design interactive activities within the slides, such as quizzes, polls, and group discussions. These activities promote student engagement and stimulate critical thinking skills. Additionally, PowerPoint enables students to present their own projects or research findings, fostering public speaking skills and boosting self-confidence. Through this collaborative approach, students can learn from each other and develop a deeper understanding of the topic.In addition to its interactive features, PowerPoint presentations offer flexibility and adaptability. Teachers can easily modify and update their slides to accommodate changes in the curriculum or incorporate new information. This ensures that the content remains relevant and up-to-date, providing students with accurate and current knowledge. Moreover, PowerPoint allows teachers to customize the pace of the presentation, catering to the individual learning needs of students. Whether it is speeding up or slowing down the slides, teachers can adjust the tempo to ensure optimal comprehension and engagement.Another advantage of using PowerPoint in the classroom is its accessibility. Students can access the presentations online or offline, allowing them to review the material at their own pace. This accessibility is particularly beneficial for students who miss classes due to illness or other commitments. They can easily catch up on the missed lessons by accessing the PowerPoint presentations and accompanying notes. Furthermore, PowerPoint presentations can be shared with students via email or online platforms, promoting seamless communication and facilitating distance learning.Despite the numerous advantages, it is important for teachers to use PowerPoint presentations judiciously. Over-reliance on slides can lead to passive learning and reduced critical thinking skills. Therefore, it is crucial for teachers to strike a balance between using PowerPoint and incorporating other teaching methods, such as discussions, hands-on activities, and real-life examples. By diversifying the instructional strategies, teachers can create a well-rounded and engaging learning environment.In conclusion, PowerPoint presentations have revolutionized the way lessons are delivered in classrooms. From enhancing engagement and interactivity to promoting collaboration and accessibility, this tool has proven to be a valuable asset in education. However, it is essential for teachers to use PowerPoint presentations in a balanced and thoughtful manner to maximize its benefits. By harnessing the power of technology, educators can create a dynamic and effective learning experience for their students.。

本文介绍了如何使用PowerPoint制作英语课件的方法、技巧与使用中应注意的问题。
关键词:PowerPoint;初中英语;应用随着教学改革的深入,多媒体辅助教学已渐渐地走进英语课堂,这无疑给英语课堂教学改革注进了新的活力。
21世纪的钟声已经敲响,我们已进入了数字化信息时代。
课堂教学由传统的“认知型、灌输型、独奏型、封闭型、统一型”开始向“视、听、说”的教学模式转变。
实现了英语课堂上学生积极参与、口脑并用、和谐高效、主动发展,着重培养学生运用英语进行交际的能力在课堂上得以体现,听、说、读、写综合训练得以加强,人文教育思想得到渗透。
PowerPoint软件是windows环境下得到广泛应用的演示创作工具软件。
它提供了功能强大的创作工具,包含有100多种模板(Template),这些模板是专家设计的演示,教师可以选择一个模板作为制作幻灯片的基础,并根据自己的需要做些修改,再输入演示的内容,这样会比一切都从头做起要方便容易得多,有利于简化教师的备课过程。
PowerPoint的每张幻灯片都可拥有标题,(Title)、文本(Test)、图形(Graphs)、绘制的对象(Object)、几何图形(Shape)、剪辑艺术图片(ClipArt)以及由其他应用程序创建的各种图表、图像等。
利用PowerPoint的控制功能,连接大屏幕投影仪直接演示,产生出一种图文并茂、丰富多彩的人机交互方式,这对于教学过程具有重要意义。
它能有效激发学生的学习兴趣,使学生产生强烈的学习欲望,从而形成学习动机。
学生有了主动参与的可能,而不是一切都由教师安排好,学生只能被动接受。
按认知学习理论的观点,人的认识不是外界刺激直接给予的,而是外界刺激与人的内部心理过程相互作用产生的,必须发挥学生的主动性、积极性,才能获得有效的认知。
这种主动参与性就为学生的主动性、积极性的发挥创造了很好的条件,即能真正体现学生的认知主体作用。
此外PowerPoint演示过程中提供外部刺激的多样性有利于知识的获取与保持。
实验心理学家特瑞赤拉(Treicher)做过两个著名的心理实验,一个是关于人类获取信息的来源。
他通过大量的实验证实:人类获取的信息83%来自视觉,11%来自听觉,两者之和就有94%。
他的另一个实验是关于知识保持即记忆持久性的实验,结果是这样的:人们一般能记住自己阅读内容的10%,自己听到内容的20%,自己看到内容的30%,自己能听到和看到内容的50%,在交流过程中自己所说内容的70%。
这就是说,如果既能听到又能看到,再通过讨论、交流、用自己的语言表达出来,知识的保持将大大优于传统教学的效果。
利用PowerPoint教学过程不仅非常有利于知识的获取,而且非常有利于知识的保持。
当你手头有一篇用Word写的文件,想把它做成演示文稿,肯定想问有没有快一些的方法?答案是肯定的:当然有。
我们只要在大纲模式上稍加改动,很快就能把Word 转化为演示文稿。
其实在PowerPoint里,可以支持很多种格式的文件,除了Word文件外,记事本、书写器、Excel、Web文件等都行。
幻灯片的文字部分做好之后,就可以插入一些要用到的图形、图表;内容齐全后,就加些必要的跳转和超级链接;然后再给幻灯片套用一个模板,或是自己加背景、设置配色方案,使幻灯片更美观;最后再考虑加些幻灯片切换、自定义动画、声音等。
动态效果处理技巧。
动画的作用是吸引观众,并使观点更突出、更醒目,不是为了哗众取宠。
所以在设计幻灯片时,幻灯片切换、自定义动画、动作设置的技术处理很重要,应用什么样的动态效果引入新的主题或解决方案;使用回旋添加悬疑或奇怪的效果;使用从屏幕中心放大效果表示揭示谜底;使用缩小效果强调观点;使用切入效果比较数据;如果是重点突出的文字,就用闪烁的效果;如果是正在读的一段文字,就用向右擦除效果;如果想控制字出现的节奏,就设定“按字母”方式擦除。
给演示文稿减肥。
往往我们做完一个文稿后,发现实在太肥大了,竟然无法方便携带它,因为软盘太小了。
下面我们就讲一下给文件减肥的问题,演示文稿肥大的主要病因大部分是图多,如果你的演示文稿中有几十幅较大的图片,那文件可能就有几兆或十几兆大了。
我们的主要手段就是拿图片开刀,就可以把图片缩小,一般最多和屏幕一样大,这步很容易,在画笔、Microsoft Photo Editor、PhotoShop等图形工具中都可以将图片缩小。
一幅bmp图片,长和宽都缩小到50%后,文件能减小四倍。
其实最有效的办法,使用JPG格式的图片文件,同样一幅图片,JPG格式只有bmp 格式的几十分之一,所以如果我们多插入些JPG格式的图片,把bmp的文件替换掉,PowerPoint 文件就小多了。
而且,BMP转换JPG也非常简单,在ACDsee、画笔等常用工具都可以轻松转换。
另外插入的图片如果是Wmf格式的剪贴画,PowerPoint文件也会很小。
除了给图片减肥外,还可以使用Gif格式的动画文件代替Avi视频文件,用Midi音乐代替wav文件,这些将会给你带来预想不到的奇迹产生,如一个20KB左右的Midi音乐竟然可以放4分多钟,而使用wav音频文件播放4分钟长至少要4MB左右,这很有用了吧。
“打包”工具用于将演示文稿和它所链接的声音、影片、文件等组合在一起,成为一个包,以便用多张软盘携带。
到达目的地时,只需运行第一张盘上的pngsetup.exe,就可以重新安装演示文稿。
单击“文件”菜单中的“打包”命令,打开“打包向导”对话框,这样就可以到另一台计算机上去播放了。
今年我曾执教一节通州市“江海之光”汇报课,授课内容为译林版教村初中第四册第十课“A Film Fan”,Sample A。
教学中我通过PowerPoint演示呈现出词cowboy,star,full,后播映三部电影让学生熟悉cartoon,war film,cowboy film,三种电影片断,学生兴趣很浓。
本课所学语法为情态动词inay的三种用法,我继续通过图片演示Mar I have this cup of tea?Yes,you may if you like。
There may be a ruler in the pencil-box。
在学生熟悉may 的基本用法后,学生以小组为单位进行操练,其中有一组同学的对话博得阵阵掌声。
A: What is in my pocket? B: There may be some money. A: No, I have no money with me. B: Are there any sweets? A: No. B: I give up. A: You may use your head. I’m a film fan, you know. B: There may be some tickets, right?A: Yes. You’re right. Look, here are two tickets. They’re for the film thisevening.. B: May I go with you? A: Yes, you may if you like. But you must finish your homework first.学生把本课的主要内容都通过这段对话表现出来了。
收到了较好的教学效果。
在使用PowerPoint进行教学的过程中,部分教师存在误区。
笔者就这个问题谈几点肤浅之见。
一、一味地追求在英语课堂上的演示效果。
在多媒体辅助教学过程中,教师仍应起主导作用,教师在英语课堂上的作用是计算机的一些功能不可也不能替代的。
如:英语课堂开头几分钟的值日生报告或师生的口头交流,是学生听说训练的很好方式。
而为了一味地追求多媒体教学课件在课堂上的展示,把由教师讲述的一部分内容变为媒体演示;甚至有时优质课评比也以是否用上大量的媒体演示作为一个必备条件。
但是,我们必须明确地认识到,英语是一种实践性很强的语言学科,必须通过课堂上大量的师生之间的英语语言交流。
学生运用英语语言进行交际的能力才能得到培养。
我们应该记住:任何时候我们都是为了教学而使用工具,而非为了使用工具而教学。
因此,PowerPoint的演示时机及数量应取决于英语课堂教学的需要。
二、用显示屏代替黑板有些英语老师把计算机显示屏当作黑板,课前将整个操练材料、问题和答案,甚至整个教案都用PowerPoint制成幻灯显示。
这样做不利于根据教学进展需要创设情景,板书内容也难以进行调整、修改。
而且,用显示屏代替黑板,一方面易造成学生视觉感知僵化;也由于显示屏一屏的显示内容有限,使学生对课文的整体感知受到影响;另一个方面,使适时创设情景引导学生进行英语语言操练变成难于把握。
总之,用显示屏完全代替黑板,不仅丢掉了传统,而且也不能发挥帮助我们解决教学方面的疑难问题。
三、用PowerPoint制作的课件代替学生的思维和操练。
现在,英语学科的课件大多侧重于有声动画的制作,它集动画和声音于一体,通过把教材中的素材以动画形式展示给学生,增加学生的视觉感官效果,较生动形象地展示教材中的语言素材,学生的视听效果得到强化,起到了帮助学生理解文章及对话内容的作用。
但不容忽视的一个问题是:这仅仅是把文中情景和有声语言展示给学生,它代替不了学生的思维,代替不了学生在教师创设的情景中运用英语进行交际的操练,也很难适应我们英语课堂上实施素质教育的积极参与,口脑并用、质疑讨论、和谐高效、主动发展的要求。
因此,切不可为了给课堂上多一点现代化教学的气息,一味地不加选择地使用课件。
