信息技术说课稿篇一
《多样的输入法》选自浙江省摄影出版社出版的小学信息技术教材三年级下册第三单元。 本节课是让学生初步地了解和感受输入法的不同方式,而学生在本堂课之前已经通过前面基础课的学习普遍对键盘的认识和部分功能键的使用有所掌握,并已逐步开始熟悉键盘的指法练习。本堂课是理论知识传授与实际操作体验相结合的一堂综合课,主要以帮助学生认识了解输入法的多样性为目标,同时通过一定的实践体验对输入法的选择有更好的感知理解,可以简单地理解为这是一堂体验式学习的综合课。
三年级的小学生尚处于好玩、好问、好奇阶段,相对的他们对理论性偏强的知识点不易理解,也不大有兴趣去集中精力,对通俗易懂、平实的语言较容易理解,对实际具体的实践操作体验方式的教学较容易接受;同时不可否认的是,学生间学习成绩存在着差距,不同程度学生的认知能力、思维能力的不同定会对课堂的教学效果有一定的影响,因此必要性的分层教学不能少。
1) 了解常见的几种输入法,通过比较,初步感知不同输入法之间的特有优缺点;
2) 学会一至两种常用输入法的使用。
通过对不同的输入法比较的互动交流等活动形式,逐步加强对复杂信息的归纳整合能力。
1)通过对不同输入法的体验实践过程培养其对信息的探索能力,为今后学会自主学习打下良好的基础。
2)通过小组协作活动,培养学生协作学习的意识和研究探索的精神,从而激发学生对信息技术的浓厚兴趣。
1)教学重点:了解输入法的多种方式,初步感知不同输入法间的区别,会简单的键盘输入。
2)教学难点:在特定的环境中应用合适的输入法。
任务驱动法; 协作学习法; 分层教学法; 赏识教育法;
学生机耳机连接;“扫描式”介绍类视频;学生机安装好语音输入法pc软件,与网络连接的电脑;百度快捷链接放置桌面;
在教学中,围绕教学的重点和难点,调动学生的主观能动性,发挥学生的主体作用,我把教学过程设计为以下几个阶段:
(一)创设情境,导入新课
(二)任务驱动,体验乐趣
(三)自主探究,总结归纳
(四)奇思妙想,畅写未来
(五)课堂总结,主题升华
具体阐述如下:
简单地播放通过语音输入来操作导航的生活小视频,一方面以其高科技性吸引学生的注意力,另一方面通过系统的画面让学生感知到简单的语音输入方式的形式,并初步体会到语音输入的快速,同时顺势引导学生可以列举其他样式的输入法,激发学生的学习兴趣,活跃课堂的气氛,调动学生的思维。(计划用时2-3分钟)————生活密切相关的事例为切入点,体现启发式教学理念。
概括常用的输入法;教师总结学生的答案,并对其进行归类,引导,和学生探讨出基本的键盘、语音、手写、扫描等四种输入方式。例如:学生可能会说:拼音输入法、五笔输入法、微软拼音输入法等,教师在这个时候要给予必要性的制止,引导学生明确此类方式总括为键盘方式,引导学生去思考除了常见的键盘方式,包括视频中的语音方式,另外还有哪些,若学生回答没有所要的答案,则教师可以就家里爸爸妈妈的输入方式或者举相关的针对于输入法特定情况的情境来完成基本输入法的列举,导出。从生活的事例作为切入点,学生更易接受;根据学生的回答,教师灵活地安排引导的方式,是学生说教师概括,还是教师引导解说,学生初步体会。在此可以实现简单的以学定教教学理念(计划用时不超过五分钟)
这个环节是本堂课的最重要的环节,环节操作中的主体是学生,主要以学生体验尝试为主,由于三年级学生一般对体验式的学习较容易接受,因此这一环节安排了尽可能充足的时间来让孩子们探索体验,通过对三种输入法的不同体验,一方面可以满足孩子的好奇心,吸引孩子的注意力,不至于上课走神;另一方面孩子充分地体验过后,潜移默化之下已经对不同的输入法有了一定的基础性的感知理解,为随后的输入法优缺点的总结归纳已作了坚实的铺垫,本课的重点也就随着该环节的逐步深入得以实现。
(因键盘输入法学生在之前就有接触,故不需再次体验)
教师简单地广播演示百度手写输入法的设置方式及利用鼠标手写汉字过程,整个设置过程相对来说还是挺简单的,短时间内学生基本上应该可以快速地完成设置并投入体验,学生获得主动权,教师主要负责引导学生利用简单的手写方式输入“手写输入法”五个字,同时帮助下接受能力稍弱的孩子完成设置。
对于速度快的同学可以借此机会引导其点击“百度一下”查找相关的“手写输入法”的介绍,进一步感受手写输入法的奇妙;也可以提前搜索“语音输入法”等进行初步了解,充分激发孩子的探究能力;学生的充分体验会对之后输入法的总结概括给予一定的支持,有体验才会有感悟;另一部分技能稍薄弱、接受能力稍弱的学生则只需借此机会初步体验手写这一输入方式即可,即在此实现简单教学分层。
事先装好语音输入法pc软件,学生尝试体验,同样在百度尝试语音输入法搜索相关“语音输入法”的资料,感知输入法(同上)。
扫描输入法在当堂授课的情况下,教师很难演示清楚,同时也没有足够的学生供学生或者老师去尝试体验,为节省时间,可在课前准备好相关的视频短片,让学生对扫描输入法有简单的了解。
综合输入法的介绍体验,以小组合作汇报或展开答辩会等形式讨论四种输入法的优缺点,展开头脑风暴,展示的过程其实就是对体验式过程的回顾,不仅可以帮助学生更好的感知输入法的不同所存在的必要性,认识到特定环境运用合适输入法的必要性。同时学生间相互交流讨论,学生在合作学习中实现难点的突破,同时培养了学生的自学能力以及与人合作的意识和探究精神;
另外阐述各方观点的同时其实也锻炼了学生的语言表达及语言组织能力,这也是与语文学科知识渗透,通过交流,分享成果,拓展了思路,使认识和情感得到提升。
体验总结完四种输入法,教师再播放“二十年后”未来科技应用的酷炫式场面——“科幻片”,教师的介入性引导式学习方式,可以更有指向性地帮助学生进行充分的思维探究,以未来的科学家为头衔,鼓励学生去畅想出未来的高科技式更快捷方便的输入法,可以提高学生自我认识度,在充分肯定自己的前提下,进行思维创新,相信会有出人意料的想法出现;另外学生畅想的方式是应用写字板进行键盘输入,这一环节其实也是对前几堂课的加强巩固。
学生分享各自的奇特的创意,新课程强调要尊重、赞赏,在充分考虑到学生的个体差异的同时,让每一个学生都有展示自我的机会,体验到成功的乐趣和喜悦。学生在展示自己观点时,教师应多给学生扬长性地评价,肯定学生的探究成果,激发学生持续探究的兴趣。,给予其必要的自信心。
最后用1-2分钟的时间简单与学生一起回顾本节内容,学生的知识技能得到提升。并和学生总结出最常用的输入方式——键盘输入,为后续的键盘相关的输入学习埋下伏笔。
本堂课教师主要承担引导性的角色,大部分时间给予学生充分的体验、探究学习,学生基本实现了在乐中学,在学中乐;主体定位为学生,根据学生在任务中的情况反馈再灵活制定教学任务简单地实现教学的分层;总结归纳环节也给予了学生充分的自主性,通过回顾感知,再对信息进行整合归纳,有意识地培养了学生对信息的处理能力以及相互协作精神,综合能力得以提升;最后奇思妙想环节的设置,孩子可以以未来科学家的身份出现,提高了孩子的主人翁意识,借此帮助孩子提高了自我的认识度,激发了孩子的想象力与创造力。

信息技术说课稿篇三
各位领导,各位老师,大家好!
我说的是小学四年级信息技术课,题目是《安徒生童话》。
《安徒生童话》是九年义务教育冀教版小学信息技术教科书第二册、第十八课,属于小学阶段总计编排的第三模块powerpoint(幻灯片)。学这节课之前,学生已经学会了往幻灯片中插入图片、设置本文档中的超链接、设置不同效果的背景、能够放映和保存幻灯片,并且也已经会录音保存。在此基础上,这一节课的主要内容有:往幻灯片中插入声音;为童话故事名设置超链接到相关网页或文档;使用动画效果,突出重点,提高幻灯片演示的趣味性;通过幻灯片预设的设计模板美化文稿。
基于以上内容,我的总体设计思想是:体现以下三个方面,一、体现与小学语文课的整合。安徒生童话作品为世世代代的人们分享,他为全世界的儿童带来快乐和幻想,其中《卖火柴的小女孩》作为小学语文教材读本,学生已经学过。本课如果和语文课相整合,必定为本课铺垫了思想感情基础,能够加深学生的学习和理解,同时,信息技术本身就是综合实践课,幻灯片作品要求科学性、技术性、艺术性和思想性相结合,学生做出来的作品带有思想性,才会具有较强的生命力。二、体现培养学生的学习兴趣:培养学生的学习兴趣是我们基础教育工作的一个重要目标之一。学生刚开始上信息技术可得时候,学习兴趣是很高的,只要别的老师一下课,马上就跑到微机室门前来,我稍微迟一会,外面就乱哄哄的。所以,学校的下课铃往往就是微机老师的上课铃。但是那种兴趣,只是不同于其他学科的新奇、好奇,一个学生,她的语数外可能学不好,但是她的信息技术并不一定比别的同学差,这完全是处于那种好奇心。所以怎样能够让学生保持高涨的求知欲,持之以恒的发展下去,是我一直探讨的问题,也是我们提出的一个研究课题。在教学中我发现,用贴近学生生活的信息内容教学,很能吸引学生;在技能教学方面,用上学生已经掌握的技术,学生就觉得有成就感,就特别有兴趣,。所以我安排了有感情的朗读《卖火柴的小女孩》其中几段,让学生录音保存,作为新课的素材,插入到新幻灯片中播放。三、体现它的工具性。安徒生童话作品共有200多部,学生不可能在课上全部阅读,让学生给同化故事名链接网址,学生自然就去浏览这个网页,这时 ,留一定的时间让学生说一说在这个网页上看到了什么,这样对以后全面学习安徒生童话作品起了指引的作用,为拓宽知识面,打开了最低的门槛。
基于以上考虑,我把这一课的教学目标定为:
知识目标:学会网幻灯片中插入声音:学会使用动画效果:学会使用设计模板。
能力目标:提高学生的上机操作能力,培养学生的信息素养。
情感目标:增强痛恨资本主义制度,热爱自己祖国的情感,注意作品思想性的体现。
教学重点:往幻灯片中插入声音,播放声音。
教学难点:恰当地使用动画效果,。
我们知道,幻灯片中动画效果比较多,学生一节课很难一一试用,更难把握用什么效果表现主题最恰当,在教学这个知识点时,我设计了采用对比的方法,让学生感受悲剧和喜剧效果的不同,培养学生用动画效果表现主题的思想意识。
教学方法:演示讲解法,任务驱动法,小组合作学习法。
学习准备:上网搜集安徒生简介及照片整理与童话故事有关的文字、图片、声音、视频及有关网址资料。
教学时数:2课时
第一课时
教学过程:
一、指名学生有感情的朗读《卖火柴的小女孩》其中3段,学生录音并保存,;同时课件演示这篇课文的文字及插图;
二、教学插入声音
1、自学课本第66页的设计,按照设计制作封面、扉页和目录页等幻灯片。
2、教师讲解演示:
以《卖火柴的小女孩》故事为例,内容主要是故事简介(文字),相关图片3张(小女孩3次擦亮火柴所幻想到的美丽的圣诞树,香喷喷的烤鹅,亲爱的奶奶)要求把着3张幻灯片插入到1张幻灯片中,需要把其中的1张作为底图,这时教学图片的叠放次序。
其次教学插入声音的方法,教师演示讲解,之后学生操作,播放试听。提问读这一段应该用什么样的感情去读?声音标志你认为放到什么位置合适?怎样播放?
教师板书插入声音的方法。
设置超链接返回目录页。
三、教学为童话故事名连接网址
导语:目录上有好几个故事名,有的读过,有的没读过,没读过的我们一定很想读,但是把它们全部做成幻灯片不太现实。如果电脑联网的话,我们可以把故事名字跟网址链接起来,这样我们就可以全面学习了。
1、以《丑小鸭》故事为例,演示教学链接网址的方法,边演示边说注意事项。
2、学生操作。为自己喜欢的故事名链接相关网页地址。教师巡视指导。
3、让学生说一说在这个网页上都看到了什么。
4、交流与本文档链接和与网址链接在操作上有哪点不同?
四、教学使用动画
1、课件演示设置了动画的幻灯片
2、演示设置动画的方法,并板书
3、用《卖火柴的小女孩》为例,演示几种不同的动画效果,然后提问你觉得哪种效果比较适合这张图片?学生讨论交流然后动手体验。
教师:卖火柴的小女孩在冰天雪地的大年夜里被冻死在街头,这是个悲剧,我们在表现这一主题时,应该用悲哀的感情、阴暗的颜色、缓慢的动作等来表达这一沉重的话题,增加人们痛恨资本主义制度的思想感情,做幻灯片时,要带着思想感情去做,这样的作品才会有生命力。
4、学生试用不同的效果
五、作业设计
课件出示:以《安徒生童话》为标题,用自己学到的知识,做一张自己满意的ppt作品。
具体要求:1、幻灯片中要有插入的声音;
2、要有链接的网页;
3、要有恰当的动画效果;
4、作业统一教至班级公共邮箱。
六、学生谈收获
这一环节主要引导学生交流这节课所学到的知识,以及产生的新问题。
我们知道,用生命教育理念来说,课堂面对的是活生生的人的活动,的即师与生、生与生的互动,是动态发展的,所以尽管我做出了种种预设,但网王动态的生成与预设不完全一致,甚至超出了预设,所以,预设的教案不是一成不变的,要灵活的应对课堂生成,我的总体思路是:以学生的发展为本,尊重学生,培养兴趣,鼓励创新,在学生学技能的同时,注重思想性的培养。
以上汇报,定有不当之处,敬请各位领导和老师们提出宝贵意见,以促进提高,谢谢!

信息技术说课稿篇五
《认识excel》是中小学《信息技术》八年级上册第二章的内容。从内容上看它是个基础性章节,从前后的联系来说它是在续word之后的又一同类软件。它是excel的入门篇章,学生对它的兴趣直接影响他在其它小节中的学习,基于这种重要性,我着重在本节中激发学生的认知兴趣、了解它的工作环境以此来铺设学生以后的学习。
知识与技能方面:
(1)、了解excel的.功能和特点
(2)、掌握excel的启动和退出
(3)、通过实例学会excel表格数据的简单输入
(4)、掌握工作表的建立和保存
过程与方法 :
(1)、培养学生学习计算机的兴趣;
(2)、培养学生敢于尝试,自主探究的学习能力。
情感态度与价值观方面:
(1)、培养学生互帮互助、助人为乐的优良品德。
(2)、有意识地培养学生学习知识的积极情感,并进一步激发学生学习计算机的兴趣。
重点:了解excel的功能和特点
难点:通过实例学会excel表格数据的简单输入
本课主要是针对农村初中二年级学生设计的。对初中二年级的学生来说他们已具有一定的独立思维能力,在信息技术知识方面,通过一年多的学习,绝大部分学生已能进行一些基本的操作,但是学生之间还是存在一定的差异,对于基础较好的学生我将放手让他们自学,而对于能力较弱的学生,让他们在同学和老师的引导、示范讲解下完成任务。
另外,由于我校有些学生上信息技术课不带课本,为改变这一现状,我经常会让学生看课本,按课本的内容一个步骤一个步骤进行讲解,对一些和以前重复的知识点,我有意让学生结合课本独立完成。这样不仅可以把学生的注意力带到教材内容上来,还可以让他们知道,如果碰到一些疑难问题,除了可以向老师、同学请教外,课本也是他们最好的老师,从而培养他们的自主学习能力。
1、自学法
本节课内容相对简单,并且和以前知识又较类似,因此我采用了自学法,这样既可以体现学生的主体地位,又可以培养学生的自学能力。
2、范例教学法
此法主张精选素材、创新素材,它强调教学的示范作用,使学生能够在此基础上举一反三、触类旁通。在操作过程中该法也融合了直观演示法和讲授法,以增强教学内容的直观性、启发性,使学生更好地从感性认识上升为理性认识。演示和讲授的过程中可将教师演示与讲授和学生的演示与讲授相结合,一来可调动学生的积极性,同时也可以发现学生操作中存在的个别或普遍问题,以便教师及时纠正。
3、讲解示范法
讲解示范法是最基本的一种教学方法,教师通过讲解示范,给学生以系统连贯的知识,使学生容易理解和掌握所学习的内容。
4、比较学习法
因为excel与word属于一母同胞的兄弟,他们之间有很多相同之处,可以相互借鉴,通过他们之间相互比较就可以缩短学生的认知途径,同时也可以缓解学生对新知识的畏惧心理。
1、尝试操作法
信息技术课是一门操作性很强的学科,学生只有通过不断的尝试操作,在实践中探索发现、试错反思,才能形成具有自我特征的知识体系,并以此提高自己的技能。
2、互帮互助法
在信息技术教学中,学生的程度差异是很普遍的现象,水平好的同学必然比水平低的同学做得快做得好,我利用水平好这部分学生的剩余时间,让他们帮助操作较慢的同学,这样既可以让学生产生荣誉
感和成就感,培养学生的协作精神,同时也可以解决教师不能全体皆顾的矛盾,以此提高教学效率。
3、自主探究学习法
学生在任务驱动下,把学生的角色从“让我学”变成“我要学”,引导学生自主探究,由此产生事半功倍的效果。同时学生也能体验到任务完成后的成就感,从而激发他们进一步学习的兴趣和积极性。
1、创设情景,激趣导入(4分钟)
我使用范例法向学生展示了他们最熟悉的成绩统计表
利用初中生强烈的好奇心来激发学生学习新知识的欲望,也为顺利实现后面的学习做好铺垫。
接下来我让学生打开课本12页,从课本中找出答案,并告诉老 师这个软件的名称。一般情况下学生都不会读出excel这个单词,所以我让学生拼读出来,学生边拼读我边板书:excel。目的是让学生节下来能根据这个单词结合word的方法来启动excel
2、回顾迁移(4分钟)
教师告诉学生:excel与word属于一母同胞的兄弟,他们之间有很多相同之处,同学们想想能不能参考启动word的方法来启动excel。
在教师的引导下,学生通过知识的回顾和迁移可得出不同的打开方式。请一学生上台演示。由于初二学生具有一定的表达能力,我会尝试让学生边演示边讲解,如果讲解的不是很清楚,老师再补充讲解。
3、自学教材,自主探索(11分钟)
在所有的学生打开excel的基础上,我出示word和excel的窗口,让学生找出他们之间有哪些异同之处,这也是对窗口组成的复习。当学生找出这些不同之处后,我让学生了解这些额外的工具按钮叫什么,学生通过自学,并根据字面意思可以得出excel添加的工具都和数据有关,这样学生在教师的引导下经过自己的自学探究得出了认知规律,这种认知不是教师强加的,所以知识的价值也得以提升。 明确任务,激发学生的好奇心、求知欲,从而促使学生去自我探索、自主学习。
4、在学生得出excel更侧重于数据处理后,为了让学生熟悉数据的输入或是说编辑栏的运用,我让学生输入19—20页的做一做“初二(1)班学生成绩表”。(18分钟)
1)教师示范操作:给学生演示如何在表中输入内容。
2)学生输入内容,师巡视指导。
5、自学保存、退出。(4分钟)
保存、退出的方法也存在借鉴,可以参考课本,或向老师、同学请教。一方面培养了学生的自学能力,另一方面又使那些能力较弱的学生在别人的帮助下也能完成任务。
6、归纳总结(4分钟)
在学生关闭excel后,让学生进行总结归纳这两个办公软件的特点,使学生能够在日常生活和学习中正确的选择办公软件为我们服务,另外,我们今天又认识了一位新的朋友——excel,并学会了如何在excel中输入内容,下节课我们再来学习如何处理这些数据。总之,在整堂课中,教师力求语言简洁,主要让学生自己探索,让学生在尝试中有所发现,在思考中发展自我。

信息技术说课稿篇七
《绿色家园》是省小学信息技术教材(上册)windows画图程序中的内容,教学对象是小学四年级学生。它是《画图》单元中关于画图知识铺垫的延伸,其目的在于让学生学会置前景色、背景色和掌握对封闭图形进行彩色处理的方法,重点是掌握利用画图的“涂色”、“喷枪”、“刷子”、“取色”等工具对封闭图形进行彩色处理的方法。根据教材的目的和特点,我确定以下教学目标:
认知目标:让学生熟悉画图功能的操作,掌握对图形进行彩色处理的方法。
能力目标:培养学生自我探索、自主学习的能力和自我创新、团体协作的能力。
情感目标:让学生自我展示、自我激励,体验成功,在不断尝试中激发求知欲,在不断摸索中陶冶情操。
重点:通过网络环境下的研究性学习活动,掌握对封闭图形进行彩色处理的方法。
难点:“彩色世界”丰富内涵的理解、体验与表现。
为了实现以上教学目标,结合教材特点,本课采用的主要教学方法有“任务驱动法”、“创设情境法”等。
通过学生已经受过的美术教育和信息技术教育(课程整合),创设一个电子画展的情境(创设情境法),设置一个个任务,让学生运用已学知识,自己动手,有机结合画图的各种操作(任务驱动法),以任务驱动的方式查漏补缺,使教学内容合理流动,水到渠成。教学中,启发、诱导贯穿始终,充分调动学生的学习积极性,注意调节课堂教学气氛,使学生变被动学习为主动愉快的学习,使课堂能在生动、有趣、高效中进行。
本课教给学生的学法是“接受任务——思考讨论——合作操练”。
建构主义学习理论强调以学生为中心,要求学生由知识的灌输对象转变为信息加工的主体。故此本课教学过程中,巧妙设计,让学生带着一个个任务通过课堂讨论、相互合作、实际操作等方式,自我探索,自主学习,使学生在完成任务的过程中不知不觉实现知识的传递、迁移和融合。
根据本课教学内容以及信息技术课程学科特点,结合四年级学生的实际认知水平和生活情感,设计教学流程如下:
(一)创设情境,激情导入
(二)步步为营,导学达标
(三)归纳总结,完成建构
具体阐述
(一)创设情境,激情导入
首先展示一个美丽的电子画展情境,学生通过已有生活体验肯定会发表自己的评价,认识到电子画展中的作品是多么多姿多彩。接着出示电子画展中未涂色的作品,学生认识到电子画展中未涂色的作品由于缺乏色彩而显得单调、不“美”。最后我抓住时机提出任务:学生自己选择图画涂色,要求注意色彩的搭配。
此环节设计目的是创设美好的学习情境,调动学生的积极性,又巧妙设计了一个显而易见的缺憾,利用学生对美好事物的向往,激发学生的学习兴趣,使学生在情景中主动、积极地接受任务,从而乐学。同时复习已经掌握的操作技巧,为后面的教学打下铺垫。
(二)步步为营,导学达标
本环节分两个层次展开:
第一层次:
1、学生选择图画练习涂色,教师巡回指导色彩搭配。2、交流评价学生作品,教师肯定学生的成绩,小结过渡。
第二层次:
1、教师指出画面内容的不丰富性,结合学生已受过的德育教育,集体讨论,引导拓展“彩色世界”的意义——美丽的色彩不仅有自然景色,还有人性的美德。
2、制定整合美育、德育和信息技术教育的目标任务:自我创作一幅体现自我个性的图画。要求对于画面设计(如内容、颜色搭配等)可利用小组协作方式来解决。遇到技术问题可通过小组讨论,向老师求助来解决。
3、集体讨论交流、评价。
这一环节是课堂重点部分,因此,我以任务驱动的方式来整合美术、思想品德和信息技术三大学科。任务是课堂的"导火索",教师通过课程整合后的优点,抛出一个个任务,激发学生的创作欲望,从而促使学生去自我探索、自主学习和团体协作、自我创新,达到掌握操作和使用的目的。同时使用优越有效的也是信息技术学科所特有的激励制度,为任务驱动法注入又一推动剂,激发学生的学习热情和创作积极性。

(3)填充底纹效果。
难点 (1)根据需要,选中并设置不同单元格的边框颜色和线型;
(2)根据需要,选中并填充不同单元格的底纹效果。
本课我采用“任务驱动法”和“激趣探究法”引导教学。
表格修饰的实际操作性较强,在教学过程中使用这样的教学方法,便于调动学生的学习兴趣和积极性,加强学生的主体参与,增强学生理解和掌握。
对于本节课重点内容,我指导学生进行合作探究学习,让学生在现有知识基础上进行自主学习,充分掌握自学方法。同时注意发挥优秀学生的示范讲解和辅导作用。这将会充分培养学生的逻辑思维能力、自学能力和动手实践能力。
1. 一生一台计算机;准备好相关表格以便拓展练习;
2. 教师机安装有广播教学控制软件,可实时控制学生机,进行演示教学及学生展示等;七、教学流程及设想
【本节课我设计了“情境感知,揭示课题” →“合作交流,探究方法” →“巩固新知,拓展应用” →“归纳总结,完成建构”四个环节。】
1. 教师出示上节课创建的课程表,引导学生回忆上节课学习的内容,复习相关知识点。〖意图:因为本单元内容具有连续性,课程表的创建是新课操作的基础,所以先进行复习,为学习新知识“预热”。
2. 教师同时屏幕出示两个“课程表”,引导学生对比。
在对比中,学生说一说两个课程表更喜欢哪一个?为什么?
教师由此引出课题《美化课程表》。〖意图:通过强烈的对比,来激发学生的学习兴趣,同时培养学生的观察能力和审美情趣。
【本环节设计目的是以强烈鲜明的课程表对比效果激发学生的学习兴趣,激发学生探索美化课程表知识的兴趣并转化为动力,提高学生思维积极性,使学生主动地、积极地接受任务,从而乐学。】
1. 修饰文字
⑴ 教师引导学生进一步仔细观察两个课程表区别在哪里?
通过仔细观察,学生发现文字、表格、颜色三方面的变化。〖意图:通过引导,激发学生学习兴趣。培养学生的观察能力和收集信息、分析问题的能力。
教师根据学生回答,分别板书:文字格式 →
表格边框 →
填充底纹 →
〖意图:通过教师板书,增强理性认识,将知识点系统化。
⑵ 教师引导学生回忆在上一单元“制作课余计划”的学习中,关于文字处理的内容,并结合出示的课程表,说一说文字的修改,可以修改什么?(视情况,可以引导学生看书p57)
根据学生回答,教师继续板书:文字格式 → 字体、字形、字号、颜色
表格边框 →
填充底纹 →
〖意图:通过引导,使学生结合前一单元学习内容,在不知不觉中完成知识迁移。
⑶ 教师要求学生根据书上p57~58内容,自主探究如何设置文字格式,并提出要求:
a. 学生3人一组,有问题互相帮助,但要注意讲清楚方法;
〖意图:培养学生团结协作精神,锻炼学生的语言表达能力。
b. 有问题无法解决,可以求助于老师;
c. 你可以按照自己喜欢的样子设置文字;
d. 比一比,看谁完成得最快。
〔教师巡视指导〕
〖意图:让学生进行探究性学习,以培养和提高学生的自主学习能力。
⑷ 学生基本完成后,教师选择性地请一位学生上前展示自己修改过的课程表,并说一说是如何设置的,然后请其他学生评价,教师适时评价。
〖预设:设置字体、字号和颜色等操作内容在前一单元的教学中详细讲述过,相信学生都已经掌握了,因此这部分内容不作为本节课重点,主要通过学生自学和演示的方式,让他们在巩固中学习,预计时间较短。
2. 设置边框
⑴ 教师引导学生说一说表格可以修改哪些地方?(视情况,可以引导学生看书p59)
根据学生回答,教师继续板书:文字格式 → 字体、字形、字号、颜色
表格边框 → 线型、宽度、颜色
填充底纹 →
⑵ 教师要求学生根据书上p59~60内容,自主探究如何设置表格边框,并提出要求:
a. 仔细看书,认真思考,学生3人一组,有问题互相帮助,但要注意讲清楚方法;
b. 确实无法解决的问题,可以求助于老师;
c. 你可以按照自己喜欢的样子设置表格边框;
d. 比一比,看谁完成得最快。
〔教师巡视指导〕
⑶ 学生基本完成后,教师选择性地请一到二位学生上前展示自己修改过的课程表,并说一说是如何设置表格边框的,然后请其他学生评价,教师适时评价。
〖意图:通过学生示范、讲解,强化操作方法并锻炼学生的语言表达能力。
〖预设:学生会有二种不同的设置方法,教师在引导学生评价的时候,可以适当评价哪种方法更简便,使学生理解信息处理的多样性。
⑷ 学生再次操作,教师巡视指导。
〖意图:重难点内容要巩固,使全体学生都能够掌握。
3. 填充底纹
⑴ 教师引导学生说一说底纹可以修改哪些地方?
根据学生回答,教师继续板书:文字格式 → 字体、字形、字号、颜色
表格边框 → 线型、宽度、颜色
填充底纹 → 颜色、图案样式
〖预设:学生可能会说出“颜色”和“图案样式”,如果说了“图案样式”,教师就势板书出来,并激趣引导,如果没有说“图案样式”,教师就暂时只板书“颜色”,在之后学生的自主探究中,一定会有学生会发现并设置,那时教师再引导并板书即可。
⑵ 教师要求学生根据书上p61~62内容,自主探究如何设置底纹效果,并提出要求:
a. 仔细看书,认真思考,学生3人一组,有问题互相帮助,但要注意讲清楚方法;
b. 确实无法解决的问题,可以求助于老师;
c. 你可以按照自己喜欢的样子设置表格底纹效果;
d. 比一比,看谁完成得最快。
〔教师巡视指导〕
⑶ 学生基本完成后,教师选择性地请一到二位学生上前展示自己修改过的课程表,并说一说是如何设置表格底纹效果的,然后请其他学生评价,教师适时评价。
〖预设:学生应该会有多种底纹效果展示,甚至会有学生直接设置成图片作为底纹,教师在引导学生评价的时候,多予以肯定,并注意学生的方法演示。
⑷ 学生再次操作,教师巡视指导。
〖意图:重难点内容要巩固,使全体学生都能够掌握。
【本环节把学习的主动权真正交给了学生,让学生通过小组合作、讨论、操作的方式探究学习,从而促进学生自我探索、自主学习和团结协作、评价解决的能力,既尊重了学生已有的知识储备,又在不知不觉中完成了知识的建构。】
1. 教师要求学生快速完成“试一试”,对几个表格自由选择一到两个进行美化修饰(零花钱支出统计表、班级学生信息表、计算机零配件价格表、水电费统计表),并提出要求。
2. 学生完成后,教师展示学生修饰的精美表格。其他学生评价,教师适时评价。
〖预设:学生作品应该比较多样化,教师选择性展示时,注意挑选不同创意、不同表格类型或是问题比较集中的作品,并注意评价。
〖意图:把所学的知识和操作方法应用于学习和生活中,培养学生的创新能力和实践能力,提高信息素养。并通过展示学生优秀作品,让学生体会到成功的愉悦,从而使其身心健康和人格健全得到良好的发展。
【本环节以丰富的操作实践刺激学生的多种感官,注重了学生的感性认识,并加强了勤俭节约的品德教育,进一步巩固所学内容,达到教学目的。培养了学生的创新能力、动手实践能力和对信息综合处理的能力,让学生获得积极地、深层次的体验。】
教师要求学生总结本节课学习成果及体会,并要求回家后,有条件的同学可以自己打印一份课程表,下节课带来,比一比谁的最好。
【本环节使学生交流心得、互评总结,帮助学生自己梳理知识。为了检验和促进每个学生达到预期的目标,发现教学中的问题,对学生的学习效果进行评价是必须的,也是有效的。目的在于加深学生对知识的记忆和理解,完成真正意义上的建构。】
根据课程改革的精神,信息技术课程必须根据学生的个体差异和不同的学习需求,爱护学生的好奇心、求知欲,充分激发学生的主动意识和进取精神,倡导自主、合作、探索的学习方式。因此,我在本课的设计中按照学生的年龄和认知规律,由浅入深、循序渐进地设计教学流程,把握好认知水平的层次,使认知领域与操作领域相结合,分清不同学习阶段的主次,激发学生兴趣,并加强操作练习内容上的合理编排组合,充分发挥及时反馈、评价、调控在信息技术教学中的积极作用。同时,本课设计还注意了学科整合,以及信息技术内部知识的整合问题,并且做到均衡学生差异,组建合作学习小组,把学习的主动权交给学生,多给学生思考和表现的机会,多些成功的体验,突出每个个体的作用,使每一个学生不仅对自己的学习负责,而且要对其他同学负责,形成人人教我,我教人人,让学生在主动参与合作中完成任务,实现知识在交流中增值,思维在交流中碰撞,情感在交流中融通。

我说课的课题是:《词语输入速度快》。我将从学习需求、教学目标、教学重难点以及教学流程四个方面来阐述。
本课是浙江摄影出版社三年级下册第三单元《计算机小作家》中的第3课,其主要内容是让学生明白用词语输入比单字输入快,了解词语输入的三种方法有简拼、混拼、全拼,并能根据词语的实质,选择不同的词语输入方法。文字的输入是今后学习工作中必备的一项技能。
学生在前两课的学习中,已经了解多种输入法,并能用搜狗拼音输入法输入单字。对词语输入的方式较为陌生,想成为打字小高手是每个学生的梦想,有学习的期望。
基于以上分析,我制订了如下教学目标:通过学生操作、经验交流、教师引导,了解词语输入速度快及词语输入的三种方法。通过“看拼音写词语”,掌握简拼输入方法。通过“看图填合适的词语”掌握混拼和全拼输入方法的综合运用。通过“词语接龙”游戏,灵活运用词语输入方式,体验词语输入与单字输入的优势。本课的重难点是:在输入文字的过程中,如果遇到是词语就用词语输入习惯;并能根据词的字数,选择合适的输入方法。为了使词语输入在学生脑海中形成初步印象,通过输入四个成语输入后的经验交流,总结得出词语输入速度快;通过两关的词语输入练习,比较三种词语输入方法,在练习、交流、再练习、再交流的过程中,掌握了重点,攻破了难点。在教学中采用了启发式教学和任务驱动教学相结合的教学方法,并提醒学生使用正确的指法。
围绕上述的教学目标,我设计了以下四个教学环节:
通过打字前的准备,回顾了前两课的内容,并以 “试一试”输入四个词语后,由输入速度最快的三位同学进行交流,得出他们都是利用词语来输入而不是单字输入,加上教师引导归纳,引出本课重点词语输入速度快,为词语输入教学做好了准备。
接着,通过学生演示,得出三种不同的词语输入的方法。简拼是最简单的一种输入方法,刚学会用词语输入的学生最喜欢用这种方法,但它并不适合所有的词语,所以通过 “看拼音写词语”这一关的练习,学生发现教师出示的词语是多字词,用简拼输入的方法比较快;通过 “看图填合适的词语”这一关练习,学生发现用简拼输入词语方法出现的词语太多,选择很麻烦,会影响输入的速度,从而启发学生思考、尝试用混拼和全拼的方法。最后学生归纳总结得出简拼适合多字词语的输入,混拼和全拼适合两字词语输入。在两关的最后都有一道拓展题,让学有余力的同学能进一步得到提升。
为更好的巩固新知,进行了“词语接龙游戏”,让学生在游戏中感受词语输入的高速和便捷,享受游戏带来的快乐。在游戏中学习,在学习中游戏,给学生创造了轻松的学习氛围。
最后通过板书整理归纳了本课所学的内容,让学生的思路一下子清晰起来,总结了本课的重难点。让学生进一步明确词语输入的优势。
纵观本课,充分体现了学生的主体地位,教师的引导作用,让学生在实践中提高技能,在对比中感悟词语输入的技巧。

信息技术说课稿篇十四
1、了解有关自然灾害的知识;
2、学会利用“主题”模板对网页进行修饰,增强网页的视觉效果。
利用“主题”模板对网页进行修饰,增强网页的视觉效果。
一、谈话导入:
师:近年来,我国的自然灾害现象很多,洪水,台风等等,严重影响着人们的生产和生活。我们要正确地认识并积极采取有效的防御措施,减少自然灾害给我们造成的损失。
自然灾害有很多种,表现也各有不同,发生的时间、地区等等都不一样,造成的破坏程度也不一样。我们要针对不同的灾害的发生特点,采取积极的预防措施,将损失减小到最低。在自然灾害来临的时候,我们要知道怎样做,了解一些临灾自救常识。
今天这节课,我们一起制作有关自然灾害的网页。
二、搜索信息
1、自然灾害的概述
地震、海啸、滑坡、泥石流、洪涝、干旱、寒潮等。
三、设计网页结构
根据p76—77进行设计制作。
四、制作网页
1、根据网页结构图进行制作网页。
a.页面设计
页面涉及内容比较多,介绍了多种自然灾害。合理安排网页中的元素,尽量使用通俗化的语言。自然灾害给人一种很压抑的感觉,因此页面颜色建议采用灰色调。首页栏目中的各个二级页面都是采用框架制作的,二级页面中栏目的具体内容都在一个窗口显示。由于首页中各个栏目,如:地震、干旱等给人的感觉都是不一样的,所以在页面的形式和颜色等方面都要以不同的方式呈现。页面的布局也可以各有不同,显示不同的风格。
2.“主题”的使用
“主题”类似于样式,还可以对其再编辑,形成新的主题,建立新模板。“主题”的编辑和使用很灵活,能达到很好的修饰网页的效果。本课涉及到的内容比较多,页面风格各有不同,学生可以编辑多个“主题”模板,形成有自己风格的主题,方便以后调用。
四、交流:主题与样式有什么不同?
“样式”可以方便地为网页中的各个元素设置背景颜色和图片并进行精确的定位控制,只能应用到页面,不能应用到整个站点;“主题”也可以方便地使页面的背景、字体等页面元素风格统一起来,它既可以应用到单一的页面上,也可以应用到整个站点。

信息技术说课稿篇十六
“奇妙的图形密铺”是苏教版五年级数学下册的一节活动课,建立在学生对基本图形的认识基础上,包括“观察与理解”、“思考与操作”、“欣赏与设计”三个部分内容。在后继的学习中学生会在八年级下册对此有更深的了解。
1、通过观察,使学生进一步了解有关平面图形的特征,理解什么是图形的密铺。
2、通过猜想、动手操作和思考,探索并了解能够进行密铺的平面图形的特征。
3、通过欣赏密铺图案和设计简单的密铺图案,进一步感受图形密铺的奇妙,获得数学美的体验,体验成功的乐趣。
4、通过信息技术的三大优势,突破难点,提高课堂效率,激发学生学习的积极性和兴趣,培养学生全方面发展。
教学重点:探索并了解能够进行密铺的平面图形的特点。
教学难点:充分利用数字平台的操作功能和交互功提高课堂效率。学生通过自己选择基本图形,再根据图形密铺的特点,发挥想象,设计图案。
根据以上目标和信息技术对于课堂教学有三大优势:传达信息的,作为一种工具,在课堂上进行有效的交互,我设计了如下几个版块:
利用信息技术的信息优势,从生活出发,让学生通过观察初步感知密铺,再由理解概念到联系生活举例到欣赏图案判断图案,感知密铺概念的三大关键:无空隙,不重叠,铺在平面上。
1、单个图形的密铺:根据学生对基本图形的了解,大胆猜测单个图形是否可以密铺,经过分类,动手操作验证和再分类,明确基本图形中单个图形可以密铺的特点,这是学生第一次简单进地行图形密铺,通过操作和评价,不仅可以让学生体验密铺的动态过程,也可以让学生充分利用平台的交互,在在线聊天中交流自己的结果和!
2、两种规则图形的密铺:通过分析和理解,学生可以进一步体会“七巧板”中三种不同的可以密铺的基本图形,任意选择其中的两种也可以密铺一个平面,而且图案更美。在此基础上学生根据要求开始动手操作,因为有了单个图形密铺的基础,学生可以更熟练的操作,所以要求也就更严格。学生可以充分利用电脑的交互功能,把自己的创作上传到数字平台的中,而后看一看其他同学的作品并且根据要求和自己的建议进行评价或者也可以利用在线聊天的功能交流想法和建议。
为了让学生可以更全面的理解概念,因此我补充了如下这个环节。
3、两种不同图形的密铺:包括单个不能密铺和单个能密铺的图形如(正五边形和菱形);单个的两种都不能密铺的图形(圆形和不规则的星形);通过对密铺图形的设疑和展示,让学生能够理解:单个的图形存在能够密铺和不能够密铺,当可以用两种或者两种以上不同图形时,我们总可以想办法让图形密铺,从而突破概念中“无论什么图形”。引出最后的奇妙的图形密铺的欣赏和设计。
其实在我们的生活中,很多美丽的图案都是用两种或者两种以上不同的图形密铺的,可以是规则的图形,也可以是不规则的图形。通过欣赏激发学生对图形密铺的兴趣和创作的欲望。一直延续到课后,学生可以利用自己会使用的软件创作奇妙的图形密铺,上传到数字平台的中,互相学习,交流,评价,使学生体验到成功的快乐!学生也可以根据教师提供的网站或者自己搜索资料,对图形密铺的知识了解的更多而充实自己。
这是我今天这节课的设计意图和理念,肯定有不到不足之处,还请各位领导和老师多多包涵,多多指教。
