大家好！
本节课是电子工业出版社出版，宁夏教育厅教研室编著的义务教育教科书，小学信息技术三年级上册中模块1《画一画美丽的宁夏川》，第1单元《认识电脑》第2课时的内容。
本节课在本单元教材内容的编排上处在学生认识计算机设备和windows桌面，并掌握启动计算机方法和熟悉关闭计算机步骤的基础上，在学生认识鼠标和鼠标指针并掌握其握法的前提下，进一步学会熟练地使用鼠标，为得心应手地使用计算机做好准备。
对于刚上三年级的学生来说，既具有对电脑充满好奇的心理，又具有怕操作不当造成计算机设备损坏的恐惧心理，且具有通过鼠标操作玩游戏的冲动。通过前面对计算机的认识，初步了解了计算机的组成设备和windows桌面，并掌握了计算机的启动方法和熟悉了关闭计算机步骤，产生了通过鼠标来操作计算机的迫切心情，特别是通过认识鼠标和鼠标指针，并掌握其握法以后，进一步激发了学生学会熟练使用鼠标的兴趣。
结合对教材和学生实际情况的分析，根据学生的心理特点，特制定如下教学目标：
1、掌握鼠标的移动、指向、单击、双击、拖动
2、让学生经历演示观察的过程，学会主动思考并探寻解决办法；经历相互讨论，汇报交流的过程，学会准确地描述日常操作；经历分析比较的过程，学会辨别并根据需要运用所学
3、学生通过体验情景环节，培养学生辨别是非的能力，通过动手操作，激发学生的学习兴趣，体验探索与创造的快乐。
根据教材对鼠标基本操作的编排顺序和知识结构体系，我确定本节课的教学重点是：
鼠标的单击、双击、拖动。
根据学生怕操作不当损坏鼠标的恐惧心理，学生在鼠标操作过程中出现双击动作不连贯，拖动鼠标时两个手指同时按住鼠标移动的情况，我确定本节课的教学难点是：
鼠标的双击和拖动
根据《中小学信息技术课程指导纲要》的要求，教育课程改革理念和本册教材的结构和体例，我确定具体教学以任务驱动为主，在任务的设置上一是采用常规教学任务，并结合教材中的试试看。
如：在教学鼠标的指向时，让学生试试看：将鼠标指针移动到任务栏左端的开始按钮上，停留一会儿，看看有什么反应；再把鼠标指针移动到任务栏右端的几个按钮上，停留一会儿，看看有什么反应？让学生通过实践和探究，既提高了学习兴趣，又体验到了计算机的奥妙。
二是创设围绕课题展开的情景游戏任务，激发学生兴趣，让学生在学中玩，玩中练，寓教于乐，在游戏的过程中习得技能。
如：我创设了鼠标像“小老鼠”，猫错把鼠标当“小老鼠”抓，引导学生抓捕真凶小老鼠还鼠标清白这一情景，并围绕这一情景任务制定了抓捕计划，每个计划分别设计了相对应的情景游戏，在完成情景任务的过程中练习鼠标操作。
计算机教室、教学课件、教学用小游戏、学习评价量化表
（一）创设情境 制定计划
创设鼠标像只“小老鼠”，被猫误以为是“小老鼠”抓住，引导学生认识到鼠标是被冤枉的，要抓住可恶的小老鼠还鼠标清白这一情景，制定有趣的抓捕计划和相对应的情景游戏，激发学生兴趣。
计划一：蹲守、围堵，实施抓捕小老鼠（失败，小老鼠逃脱）
游戏：猫蹲守围堵小老鼠，不让老鼠从洞口逃脱，让学生练习鼠标的移动
计划二：围住藏匿地点，加派人手，再次实施抓捕（抓捕成功）
游戏 ：围住小老鼠，等老鼠从洞口出来就砸用锤子将老鼠砸晕，抓住小老鼠，让学生练习单击
计划三：严惩小老鼠，还鼠标清白（将小老鼠拖去喂猫）
游戏：通过拖动将小老鼠送入窗口给猫当午餐，让学生练习拖动。
（二）探究新知 苦练本领
借助情景计划，引导学生要想使抓捕行动更有效，必须苦练基本功进入常规教学任务当中。
1、鼠标的移动：握住鼠标在桌子上滑动
任务一：根据教师口令从上、下、左、右、左上角、右下角、右上角、左下角几个方向上移动鼠标，让学生动手操作并指名学生演示。
2、鼠标的指向：把鼠标指针移动到某个图标上，按钮上或需要的位置。
试试看：将鼠标指针移动到任务栏左端的开始按钮上，停留一会儿，看看有什么反应；再把鼠标指针移动到任务栏右端的几个按钮上，停留一会儿，看看有什么反应？将鼠标指针再指向我的电脑图标，看看有什么反应？
3、鼠标的单击：用手指快速地按一下鼠标按键后立即松开。
试试看：把鼠标指针移动到某个图标或按钮上，分别单击左键、右键，观察图标有什么变化？（学生讨论、汇报）
4、鼠标的双击：用手指快速地连按两下鼠标左键后立即松开。
试试看：将鼠标指针指向桌面上的“我的电脑”图标，双击它，看看电脑桌面会有什么变化？
任务二：让学生指向我的电脑窗口上的三个按钮了解它们各自的名称，并单击最大化和还原按钮观察窗口变化。
5、鼠标的拖动：将鼠标指针移到某个对象上，在按住左键不松开的情况下移动鼠标，当鼠标指针移到需要的位置时再松开左键，图标就会移动到这个位置。
试试看：把鼠标指针移到“我的电脑”窗口右下角边框处，看看指针有什么变化，指针形状改变后，按住左键拖动鼠标，看看窗口怎样变化？单击关闭按钮能不能关闭窗口？
（三）实施计划 展示技能
进行完常规教学任务以后，让学生进入情景任务运用所学实施抓捕计划，通过游戏对小老鼠实施抓捕，练习鼠标操作，使学生更熟练的使用鼠标。
计划一：蹲守、围堵，实施抓捕小老鼠（失败，小老鼠逃脱）
计划二：围住藏匿地点，加派人手，再次实施抓捕（抓捕成功）
计划三：严惩小老鼠，还鼠标清白（将小老鼠拖去喂猫）
（四）巩固练习 接受表彰
完成情景任务后，通过游戏“小奖状”中的奖状，对学生抓捕小老鼠有功进行表彰，让学生进行鼠标单击、双击、拖动综合练习。

说课稿数学 说课稿ppt篇二
一、说教材
今天我要说的是苏教版小语第五册语文教材中第22篇课文《金子》。课文讲了彼得·弗雷特在淘金无望，便留下种花，终于获得成功的故事。旨在告诉我们要获得财富或成功就必须付出辛勤的劳动，想靠意外的收获是不现实的。课文内容简明，情节曲折，蕴含的道理深刻，是一篇人文性较强的培养学生观察、想像及朗读能力的好材料。“金子”在课文中出现了多次，含义也各不相同。对于学生来说，理解“真金”的含义，体会彼得获得成功的过程，是教学的重点，也是教学难点。因此，我在设计教学时关注了以下几点：
1、努力创设情境，帮助学生走进文本。
我通过引导学生找重点句，抓关键词，创设各种情境，指导感情朗读将学生带入文本，感受彼得在淘金无望时的孤独无助以及种花成功的喜悦。
2、坚持“对话”理念，引导学生理解课文。
课堂上通过学生、教师与文本之间对话，讨论、交流，培养学生理解、欣赏和评价的能力。
3、激发学生的想象，引导学生体验“生活”。
给孩子一个轻松愉快的环境，使孩子充分发挥想象。在交流，体验中感悟“不劳而获只能是个幻想，辛勤劳动才会梦想成真。”“坚持＋智慧＋勤劳＝成功”“劳动创造一切。”
为此，根据课程改革和语文新课程标准的基本理念，我确定如下教学目标：
1、运用已有的识字经验和方法，学会“坑、附”等10个生字，理解新词，能正确、流利、有感情地朗读课文，通过 对 课文的诵读品味，读懂课文内容。
2、以学定教，通过创设情境，讨论、朗读等方式来培养和提高学生语言感悟能力、朗读能力和评价能力。
3、体悟彼得·弗雷特是靠自己辛勤的劳动，终于获得了成功，让学生懂得想要通过意外的收获获得财富或成功是不现实的，必须付出诚实劳动的道理。
二、说教法
由于本篇课文是一篇人文性较强的文章，所以我在本课教学中主要使用了朗读感悟法。
三、说学法
阅读是学生的个性化行为，本课教学中我确定了本课学生的学法以朗读感悟为主，引导学生通过朗读探究性、创造性地感受、理解、评价和鉴赏文章。进而培养和提高学生的思维能力，超越文本，链接生活。
四、说教学过程
根据本课的的教学目标以及第二学段的要求确定，1、2两个目标是教学重点。“金子”的本意是指物质层面的“贵重金属”，而在课文中，“金子”是指
诚实、勤劳的高尚品质。本文用“金子”做题目，同时又以“金子”为线索，贯穿全文，因此，理解“金子”的含义，深化学生的阅读感受是教学难点。我准备安排两课时引导学生达到预设的学习目标。
第一课时：引导学生把课文读正确、读流利，通过图文对照，从整体上感知课文内容，获得初步的情感体验：在语境中理解生字新词，指导两个字“甘”（独体字，注意笔顺）“钱”（左右结构，形声字），注意“盆”和“坑”音节，引发猜想，建构阅读话题，能基本说出本故事的大意。
第二课时：借助多媒体，创设情境，引导学生反复有感情地朗读课文，帮助他们读懂课文内容，了解彼得·弗雷特通过辛勤劳动获得真金的曲折过程，教育学生向彼得·弗雷特学习，培养自己靠诚实、勤劳获得成功的高尚品质。另外，引导学生在反复诵读课文的基础上，开展语文实践活动，进一步激发情感，引导学生积累丰富的语言。
下面，我着重讲第二课时的教学：本课时我打算分四个环节进行组织教学： 复习旧知，精读感悟，拓展延伸，个性作业。
下面我具体地来说一下：
第一环节：复习旧知。
我先引导学生有感情地朗读词语，接着启发学生交流初读课文后所了解的知识，然后根据学生回答，引导质疑“彼得的梦想是什么？他实现了吗？你是从哪里知道的？学生自然而然的就顺着我的问题注意到最后一段的课文，然后引出彼得的话：我是唯一一个找到真金的人，我的金子就在这片土地里，引导出问题：彼得是怎样找到真金的？这是课文的重点也是难点，所以我在上课后不久就提出，目的是让学生有充足的时间去思考。通过这一统领全文的问题，引导学生再次走进文本，去细细地感受。
第二环节：精读感悟，悟中明理。
1、阅读是学生的个性化行为，重在自悟。我以一个开放性的问题“彼得是怎样找到真金的？”要求学生默读课文，边读边划出课文中自己找到的句子。要求先读有关句子，再体会体会。在全班交流时，我以学定教，根据学生的发言相机地出示词句，加以适时点拨。具体指导，品读体味。如学生在自读第一自然段的基础上，扣住“听说、无意”明白消息的不确定性，但淘金者们仍“蜂拥而至”，体会他们缺乏理智，盲目跟从。接着抓住“一无所获、扫兴离去”，体会人们怀着失望离开的不幸。通过对淘金者们由“高兴”至“扫兴”两种截然不同的感情地进一步对比感知，指导有感情地朗读。学习第二自然段时，抓住“埋头苦干、几个月、几乎翻遍了”理解从精力上、时间上、工作量上说明彼得作的别人无法比拟的巨大付出，通过朗读让学生体会彼得是能吃大苦、耐大劳的人，但结果是“没有发现一丁点儿金子”，让学生明白上文的传说的不可靠。在品读词句的基础上，体会彼得由“希望”转向“失望”的失落心情，再次练习个性化朗读。在交流第五自然段时，我让学生读好词语“若有所悟”，并说说彼得“悟”到了什么来具体地展开学习。如“这里没有找到金子”，让学生边读边思考：彼得本来要离开，是什么使他留下来？留下后又是怎么做的？引导学生读好文中相应的句子，并描述一下彼得看到的情景，体会希望的产生，明白这希望就在这肥沃的土地里，正是这希望使彼得留下来。再让学生观察插图，想象彼得是怎样用“全部精力”种花的，此时，我出示图片：每天太阳刚刚升起，彼得就要-----；当夜幕降临时，彼得要------；在炎炎烈日中，彼得要-------；在大雨如注时，彼得要--------。等等，一方面是为了锻炼学生说话的能力，另一方面也让学生们
从内心体会彼得所经历的困难，为下面揭示真金买下铺垫。接着，我把重点放在理解彼得所说的话是什么意思上。让学生思考：彼得从这块土地里究竟获得了什么？你能悟到些什么呢？学生通过交流，知道彼得并非获得真的金子，而是获得了“财富”。最后学生畅谈感悟的基础上归纳：只要勤劳耕耘，任何土地都会奉献出你需要的“财富”。 抓住“不“不无骄傲”、“唯一”等词语，引导学生体会彼得非常自豪的心情，练习个性化朗读。
第三环节：拓展延伸，畅谈梦想。
这个环节是建立在理解文章基础之上，让学生畅谈自己的梦想，培养学生语言表达能力，同时把文本与学生实际联系起来。最后配乐朗诵《梦想》，鼓励学生通过自己的辛勤劳动来实现自己的梦想。
第四环节：个性化作业。
本环节本着语文课程标准要求“关注学生的个体差异和不同的学习需求”的准则，另外，进入中年段以后，阅读教学应拓展学生的阅读范围，拓宽视野，拓展和增加有效的积累，让学生个性作业，可以提高学生的语文素养。
五、说板书设计
板书设计上，我力求简单明了。抓住彼得实现梦想过程中的几个关键性词语，概括文章的主要内容，步步引导，让学生明确只有勤劳才能致富的道理，明白这就是彼得取得的“真金”
说课稿数学 说课稿ppt篇三
各位老师：
大家好！今天我说课的题目是《修饰倡议书文字》，我将从以下几个方面来进行说课：说教材，说学生，说目标，说教法，说学法，说媒体，说设计，说小结。
本课是选自电子工业出版社《小学信息技术》第3册第1单元 班级环境齐关心中的《第3课 修饰倡议书文字》，教学对象是小学四年级的学生。
：格式工具栏中的`“字体”、“字号”、“字体颜色”的设置以及格式刷的使用。
本课是教材关于word20xx文字处理知识的铺垫延伸，并且贯穿着以后整个的word知识教学，是学生能够顺利、快捷操作使用word的基础之一，也是形成学生“了解熟悉－技巧掌握－综合运用”这一合理知识链的必要环节。
：（1）文字字体、字号的设置方法；字号的表示方法及大小比较。（2）文字颜色的设置方法。（3）格式刷工具的使用。教学难点：（1）对文字进行合理地美化。（2）各种文字格式的搭配。
学生在学习前两课的基础上，已经初步认识了word软件，基本掌握了文字输入及选中、修改等相关操作。本课将让学生了解和掌握word软件中设置文字格式的基本操作，并在学习过程中感受美，欣赏美，培养审美意识。
另外，本课的教学对象是四年级的学生，他们对学习计算机非常感兴趣。不喜欢计算机理论知识的学习，非常喜欢实践知识，擅长于动脑动手，但很难把握操作技巧，因此在本课的教学中，注重学生自己动手去探索，去实践。
根据信息技术课程标准的要求和教材特点，结合四年级学生的认知规律，我将本节课的教学目标确定如下，它们分别是：
⑴ 学习了解文字修饰的基本方法，并能熟练掌握。
⑵ 了解格式刷，并能使用格式刷进行快速设置。
通过教师讲解和学生探索实践，逐步掌握文字美化的方法，能够根据实际需要完成文字修饰工作。
通过学习培养学生良好的审美能力，在不断尝试中激发学生的求知欲和创新思维，同时，继续培养学生“先选定，后操作”的操作规范。
说教法：通过对学生学习情况的了解，以及新课程标准要求：课堂教学要以学生为中心，充分发挥学生的自主能力和创新能力，调动学生学习的积极性，本着这个主导思想，结合四年级学生的特点，在教学过程中教师作为引领者，通过情境教学，创设情境，激发学生的学习动机和学习兴趣，有效运用心理激励，让学生乐学；通过任务驱动法，引导学生积极思考，让学生动起来，成为课堂上学习的主体；通过尝试教学法，放手让学生做力所能及的事，体验收获成功的快乐。
说学法：课堂不仅是让学生获得知识，更重要的让学生掌握学习知识的方法。为了更好的体现学生的主体地位，因而在课堂中以“动中学-学中探-探中悟”的形式，通过让学生动手实践、自主探究、合作交流，使整个学习过程活起来，动起来，学生在课堂上通过动口动手又动脑，既获取了知识，又培养了能力。
1、硬件资源：计算机网络教室及教学系统；2、软件资源：powerpoint
根据本课的教学内容及信息技术课程学科特点，结合学生实际认知水平和生活情感，我设计的教学流程大体如下：
1、创设情境，激发好奇；
2、导入新课，揭示课题；
3、由扶到放，学会学习；
4、创作交流，发现问题；
5、成果展示，课外延伸；
下面我将逐步进行解说：首先，创设情境，激发好奇心。爱因斯坦说过，兴趣是最好的老师。小学生对新奇事物充满好奇心，因此，在新课导入时，我利用一段外星小朋友爱丽丝来地球求学的视频，以爱丽丝的三个难题贯穿整个教学过程，创设情境，充分激发学生的好奇心和学习兴趣，为后面的课堂教学服务。
具体呈现如下：同学们，今天在咱们的课堂上来了一位特殊的朋友，让我们一起来看看他是谁吧？（播放视频）原来是火星小学来的爱丽丝，她想和大家一起来学习，同学们，你们愿意和爱丽丝一起学习吗？既然同学们都说愿意，那我们就把爱丽丝请进咱们的课堂中来吧！爱丽丝还带来了三个难题，你们愿意帮助爱丽丝，和她一起解决吗？看来，咱们班的同学们还真是一帮热心的好人呐！
接下来，进入第二个环节，导入新课，揭示课题。也就是爱丽丝的第一个难题：展示两份倡议书，一份未修饰文字的倡议书，一份修饰过文字的倡议书，比较这两份倡议书，揭示课题。
具体呈现如下：首先我们一起来看看爱丽丝的第一个难题吧！这是两份倡议书，爱丽丝要我们帮忙选一张最好看的贴在他们班级的宣传栏里。请同学们仔细观察这两份倡议书，说说它们有什么不同，哪一份倡议书更适合张贴在宣传栏里呢？嗯，文字的大小不一样，颜色不一样，字体也不一样。说的真好，你观察的可真仔细。那你们知道这份好看的倡议书是如何制作的吗？今天就让我们一起来学习《第3课 修饰倡议书文字》
第三个环节，由扶到放，学会学习。以教师提醒文字的美化可以使用“格式工具栏”为线索，以尝试设置倡议书标题文字格式为：“黑体”、“一号”、“深蓝”为任务，鼓励学生自己去探索发现“格式工具栏”中各个按钮作用，放手让学生动手实践。
在此环节中，我设置了两个部分，第一个部分是以教师展示格式工具栏在word界面的位置，简要介绍利用格式工具栏可以设置文字的字体、字号以及字体的颜色，之后布置任务：鼓励学生尝试设置倡议书标题文字的格式为：“黑体”、“一号”、“深蓝”，在操作过程中注意思考以下几个问题 ：（1）“一号”文字和“四号”文字，哪一种字号的文字更大一些？（2）“8”和“28”，哪一种字号的文字更大一些？ （3）你能将你的操作秘籍分享给大家，分享给爱丽丝吗？遇到问题可以从课本中寻找答案。由于学生的计算机水平存在差异，因此，已经完成操作的同学可以帮助自己身边的同学完成任务。在这一部分的教学中，可以请完成的比较熟练的同学演示操作，分享经验。通过这一部分的教学，不仅可以培养学生遇到问题从课本中寻找答案的习惯，也可以通过学生之间相互帮助，促进学生之间友谊的加深。第二个部分，爱丽丝的第二个难题：利用提前用屏幕录制专家录制好的视频，提出问题：为什么爱丽丝的操作不正确，你能帮她找到原因吗？引导学生得出结论：没有提前选定正文的内容，然后再操作。通过这个环节的设置，可以帮助学生养成“先选定后操作”的操作习惯。同时也能帮助学生进一步明确文字字体、字号以及颜色的设置的方法。
第四个环节，创作交流，发现问题。爱丽丝的第三个难题。展示爱丽丝的语文、数学作业以及作业要求，你能帮助爱丽丝解决这个难题吗？选择你最感兴趣的那一份作业帮帮爱丽丝。
在这一个环节中，学生可以根据自己的喜好选择一个任务进行操作。但在这两个任务中，都有同样的一个问题，要对不同位置的文字进行同样文字格式的设置，如果要一个一个进行设置，那肯定会比较麻烦。就此提出问题：“有没有什么办法可以让我们更加快捷的帮助爱丽丝完成作业要求？”引出格式刷的教学。教师先演示格式刷的使用方法，之后学生自己动手进行操作。这样进行设计，更能突出使用格式刷进行文字格式设置的便捷性，也使格式刷的介绍变得更加顺理成章了。
最后一个环节，成果展示，课外延伸。收集学生帮助爱丽丝完成的作业，采用学生自评、互评、教师评多种评价方式相结合的方法，评选出最佳作业，给与表扬和奖励。
同时，为了鼓励学生学以致用，将课堂中学到的知识应用到生活中，建议学生自己书写一份班级倡议书，并根据自己的审美观，设置文字的格式，做好文字美化工作。在这一环节中，我采用了学生自评、生生互评，教师评价多种评价方式相结合的方法，一方面可以培养学生的语言表达能力，能够正确客观的评价自己及他人，另一方面可以培养学生形成正确的审美观。在这一部分当中，我还将采取小组的推荐的形式，选取几份有代表性的，做的好的作品展示给全班同学看，激励学生不断学习，培养学生的竞争意识。
课堂中知识的学习也是为了能够更好的方便生活，服务生活，因此，我鼓励学生能够将课堂中学到的知识应用到生活中，能够了解计算机在生活中的应用，培养学生的计算机使用意识。建议学生自己书写一份班级倡议书并进行文字的美化，不仅贴近学生的实际生活，容易引起学生的兴趣，同时也能帮助学生巩固课堂所学。
最后，说小结：本课在教学中以教师为引导，以学生为主体，对本节课的内容进行回顾，说说自己的本节课的收获，以及自己在操作过程中能和大家分享的一些小窍门。通过这一环节 的设置，让学生及时对自己的学习成果进行回顾总结，做到温故而知新，分享小窍门更能让集思广益，这些也为下节课的学习打下了基础。
说课稿数学 说课稿ppt篇四
“圆的认识”是九年义务教育六年制小学数学第十一册第四单元“圆”中的第一节课。这节课的内容包括：圆的特征、圆心、直径和半径。
“圆的认识”是在学生直观认识圆和已经较系统地认识了平面上直线图形的基础上进行教学的。它是学习曲线图形的开始。它与“圆的周长和面积”、“轴对称图形”的学习关系十分密切。所以正确树立圆的表象，掌握圆的特征，是本课的首要任务。
根据教学内容、教学大纲要求以及学生的认识特点、年龄特征确定本节课的教学目标为：感性目标：使学生认识圆，掌握圆的特征；理解和掌握在同一个圆里半径和直径的关系。
理性目标：让学生通过观察、实验、等数学活动过程认识圆，进一步发展空间观念和初步的探索能力，感受到圆的美。
本节课的教学重点是掌握圆的特征；理解同圆或等圆中半径和直径的关系。因为这是今后系统地学习“圆”的知识的重要基础。
根据教学内容知识间的内在联系和学生的认知规律，遵循教学有法，教无定法，贵在得法的原则：
1、根据本节课的教学内容及学生的认识水平和认知规律，这节课采用演示、操作等直观方法进行教学。通过教师的教具演示和学生的画、折、量等动手操作，使学生获得充足的、丰富的感性材料。在充分感知的基础上，通过叙述操作过程，把感知经过思维转化为表象，并在教师的指导下，抽象概括出圆心、半径、直径等概念。
2、在教学中充分利用学生生活中的问题，引导学生通过自主学习去思考问题，掌握知识。认识圆的特征，探索求圆的特征的方法，使学生在自主的活动中学会学习。
进行了如下设计:
（闭眼联想）八月十五，中秋，全家人团聚一起，品月饼，赏圆月当空。门前是一片平静的湖面，一滴水从上面滴入后，在水面上荡一圈圈水纹。在这一句话中你感觉到这些景色美吗？那些事物与景色与本节课内容有关？
1、初步感知圆
首先让学生举例说明生活中哪些物体的形状是圆的。让学生初步从生活中感知圆，培养空间想像能力, 形成正确表象——圆是一种平面上的曲线图形。
（1）找圆心
首先让学生把事先准备好的圆形纸对折后打开，用笔和直尺把折痕画出来，并在圆形纸的其他位置上重复上面的折纸活动二、三次。操作后，问：“你发现了什么？”学生亲手操作后，发现所有的折痕都会相交于一点。这些折痕都相交于一点，正好在圆的正中心，我们数学上把这一点叫作圆心，用字母“ｏ”来表示。设计意图：通过学生的直观操作，使学生的学习过程“动作化”，调动学生多种感官参与学习，并有意设置一些认知冲突，让学生积极主动地参与知识的形成过程。
（2）认识半径、直径，采取学生独立与文本对话，教师组织学生分析关键字眼的方法进行。设计意图：培养学生阅读文本，对话文本能力。
（3）半径和直径的关系
分组讨论利用“研究发现单”定出研究目标，在一个圆里，半径和直径有什么关系？通过测量和比较，让学生理解和掌握在同一个圆里半径和直径之间的关系，让学生用含有字母的式子表示半径是直径的一半、直径是半径的2倍关系。得出d = 2r与r = 2/d的字母公式，并在练习中通过填表强调了圆内半径与直径的对应关系，还要求学生在圆内一些线段中，找出半径和直径。 设计意图：合理发挥学生的主体作用，让学生动脑、动手、动口、动眼，自主探索知识的形成与发展，并及时巩固学习成果。
练习是巩固新知，形成技能的重要手段，对学生的创新思维能力的培养起着举足轻重的作用，这一部分可通过一些拔高练习达到知识的进一步深化。有机地配合新知的学习，讲练结合，最大限度地发挥习题发展学生思维能力的作用
1、课后作业88页1—4
2、判断题。（对的打“√”，错的打“×”）
经过圆心的线段都是直径。（）
所有连结圆上两点之间的线段中，直径最长。（）
直径是4厘米的圆比半径是2厘米的圆大。（ ）
3、猴子造车，一辆轮子是方的，一辆轮子是圆的。
通过“这节课你学会了哪些知识？你最大的收获是什么？你还有什么知识要提出来？”来使学生进一步内化所学的知识，自主地完善自己的认知结构。
板书设计： 圆的认识
圆心：用字母“o”表示。
直径：通过圆心并且两端都在圆上的线段；用字母“d”表示。
半径：连接圆心和圆上任意一点的线段；用字母“r”表示。
在同一个圆里 d = 2 r 或r = 2/d
说课稿数学 说课稿ppt篇五
各位评委老师：
大家下午好。今天，我说课的内容是鄂教版五年级第六单元第17 课，课题是《隔窗看雀》。本单元以“人与动物”为话题，安排了三篇课文。《隔窗看雀》在本单元起着承接作用，透过这扇窗户，听到雀儿的鸣唱，为我们的生活增添了情趣。生动地再现了人与自然的和谐之美，
我的说课分为四个部分，分别是：说教材，说教法学法，说教学步骤，说板书。
首先我们进入第一部分：
《隔窗看雀》这一课构思新颖，语言质朴，蕴意深刻。文章前5段，作者描写了麻雀的“跳跃”、“翘尾巴”“飞行”，喜爱之情溢于言表。妙的是作者笔锋一转，在第6自然段提炼出麻雀在平凡生活中的心灵写照：“忙碌而不羞愧，平庸而不自卑”，并进一步诠释它坚忍、乐观、有责任感的生活态度.最后，作者用精妙的语言描写了麻雀是“点缀在人类生活中的活标点”，敬重之情油然而生。
扬扬洒洒的文字让人浮想联翩，更令人感慨不已。但作者由“雀”到“人”、寄情于物的写法，特别是“忙碌而不羞愧，平庸而不自卑”的深刻内涵,学生领悟还较困难。作为教师，我们应该架起学生和文本之间的桥梁，让学生掌握文本的重点，理解文本的难点，落实语言文字的训练，以实现三维目标的整合推进。
根据以上对教材的分析本篇文章的教学，我预计2课时完成，第一课时理清文章脉络，扫清字词障碍。下面我就第二课时进行说课。通过研读，我制定了如下的教学目标和重、难点。
cai出示：
1、正确、流利、有感情地朗读课文。背诵自己喜欢的部分。
2、通过品味语言，想象画面，理解“忙碌而不羞愧，平庸而不自卑”的含义，培养学生的语感，帮助学生掌握边读边想象的学习方法，激发学生对平凡生活的热爱，形成健康的价值观。
教学重难点：理解“忙碌而不羞愧，平庸而不自卑”的可贵，引发学生对生活的初步思考。
我始终牢记：学生是课堂的主体，语文课堂就要有语文味，语言学习就是要唤醒学生的内心体验。而教法和学法往往是相互交融的。因此，我选择了如下的方法。
cai出示：
自主探究合作交流 抓词扣句体会情感 以读代讲引发共鸣
创设情境想象补白 拓展练习深化感悟
教学中，我紧紧抓住“忙碌而不羞愧，平庸而不自卑”这个中心句上牵下联，层层剥笋认识麻雀的形象，理解句子的含义，激发学生对平凡生活的热爱。
整个教学过程，我设计了四个环节。
cai:
复习旧知导入 雀儿巧妙再现
抓词扣句体会 雀儿深铭心中
图文并茂想象 雀儿点缀生活
隔窗放飞思想 雀儿唤醒生命
首先，进入教学过程第一个环节：复习旧知导入，雀儿巧妙再现
在复习旧知，导入新课的环节中，我让学生静静地观看麻雀活动的镜头，然后回忆上节课所读到的有关描写麻雀生活的语句，用朗读的形式再现出来。
作者看着窗外的雀儿门，此时有什么感受？
接着让学生自由浏览课文6-11自然段，找出文中最能集中表现作者感到麻雀“忙碌“、“平庸”的句子，并勾画出来。
紧接着，进入到教学过程第二个环节：抓词扣句体会，雀儿深铭心中
进入这个环节我提出第一个层面的问题：你从哪些词句感受到麻雀的“忙碌、平庸”？
默读课文，圈点批注，集体交流：首先感受麻雀的“忙碌”。学生说到哪就让他读哪；读到哪，老师就评价、反馈、指导到哪。
在此我对麻雀的“平庸”进行了重点指导。
cai：
“它不会翱翔，也不会盘旋，它不能像那些大的禽类那样顺着气流，直上白云苍穹之间，作大俯瞰或大航行。它从一棵树到另一棵树，从一个楼檐到另一个檐台，与人共存，生存与市井之间……”
让学生找出这段话中体现麻雀“平庸”的关键词（学生不难找出“不会”“也不会”“不能”这些关键词去体会“平庸”，教师及时进行评价。）
然后，让学生结合课文的内容，说说麻雀会些什么，又只能做些什么这样的句式来。
再通过朗读，麻雀与大禽类之间的差距形成鲜明对比，学生不由得从心底里感慨麻雀是多么“平庸”啊！
在此基础上，我继续紧扣中心句，提出第二个层面的问题，即核心问题：为什么作者认为它“不羞愧，不自卑”呢？
学生们很快发现了文中第6段中的一个重点句：
cai:
低飞，跳跃，啄食，梳理羽毛，发出永远幼稚的鸣叫，在季节的变化中坚忍或欢快，有责任感地孵蛋和育雏……活着。
此句理解分为四个层次：
1、通过自读，理解文本内容；
2、再读交流，找出重点词深化理解，体会到麻雀总是叫个不停、忙个不停，很坚强、快乐的活着；
cai出示：
低飞，跳跃，啄食，梳理羽毛，发出永远幼稚的鸣叫，在季节的变化中坚忍或欢快，有责任感地孵蛋和育雏……活着。
低飞，跳跃，啄食，梳理羽毛，发出鸣叫，在季节的变化中孵蛋和育雏……活着。
3、将句中的“永远幼稚的”“坚忍和欢快”、“有责任感”这些关键词隐去与原句进行对比读，让学生在读中自主感受到作者的情感倾向；
通过这两个例句的对比读，学生们自主感悟到：去掉这三处形容词，文章逊色很多，从中也感受不到周涛先生的情感倾向，也很难读出自己的感情。
4、拓展练习，内化提升。让学生通过四个不同句型的练习，达到理解、共鸣、升华的目的，更重要的是进行有效的练笔。
教学到这一步，我预设情境，师：“同学们，想象一下：在最难熬的冬天和夏天，或者当雀儿面对遭遇时，它是怎样地活着呢？你能用这样的句式说一说吗？（逐步放手让学生说）
同时cai出示：
冬天，寒风凛冽，大雪纷飞，雀儿依然坚忍地活着。
夏天，烈日炎炎，酷热难当，雀儿依然欢快地活着。
当雀儿遭到追赶、啄咬时，雀儿依然坚强地活着。
为了自己的孩子，雀儿必须乐观、有责任感地活着。
通过这种句型的练习引导学生联系生活，将抽象的文字具体化、形象化：让学生把填写完整后的句子读出个性化的情感体验。
过渡：当同学们把课文读到这里，我相信在大家的心里，这绝不仅仅是一只“忙碌平庸”的麻雀那么简单了。你能用“虽然……但是……”这个关联词，来表达你对雀儿更深的认识吗？
cai出示：
虽然雀儿______________，但是______________，依然______________地活着。
学生完成练习后老师小结：是呀！麻雀在忙碌的生活中，在面对各种困难时，它始终乐观、坚强、有责任感。难怪作者会产生深深地敬意，发出这样的赞美，一起读！——“忙碌而不羞愧，平庸而不自卑”！
以上环节我设计的意图是：任何语言训练都需要通过“听、读、说、写、思”才能真正内化为自己的语言，才能表达自己的内心体验。所以在这个环节中，我相机引入了几处练笔与拓展，引导学生由外而内，整体、全面、深刻地认识了麻雀的形象，使三维目标整体达成，体现了教学的有效性。让雀儿的形象跃然眼前，对它的“忙碌、平庸”有了一个完整、清晰的认识。
进入教学过程的第三个环节：图文并茂想象，雀儿点缀生活
课文进入到第9自然段，作者以审美的眼光重新看着窗外的雀儿，用精妙的比喻和奇特的想象描绘了四幅画面，让我们感受到生活中有了雀儿的点缀生命充满了活力，生活更加美好。
cai出示：
它是点缀在人类生活中的活标点：落在冬季枯枝上时，是逗号；落在某一个墙头上时，是句号；好几只一起落在电线上时，是省略号；一对儿追逐翻飞，累了落在上下枝时，就是分号。
此处突破，我采用读中想象的学习方式，体会文字的精妙之处。同时选择清新的纯音乐作为辅助理解的工具。通过读想学生很快就能发现：这段话运用了比喻、排比的的手法：把雀儿比作活标点，形象地写出了雀儿体形小巧、形态各异的特点；排比句流露出对雀儿喜爱欣赏之情。“朗读是学生学习语文最好的方法” （配乐读）此刻流淌出音乐，让学生朗读，舒缓优美的音乐，流畅挥洒的文字，纯净甜美的声音将这段文字演绎得淋漓尽致，这美丽的瞬间自然定格在师生的脑海里！”
这个环节我的设计意图是：赏析精彩语段，变“读话”为“作画”，对语言文字进行再创造，培养学生对语言的鉴赏力和创造力，品味语言，积累语言。
到此教学进入到最后一个环节：隔窗放飞思想，雀儿唤醒生命。
有了对文本的理解，对作者感情的领悟，学生也就有了自己的深刻思考，有了自身独特的感受。应该说我们的文本教学任务已经完成，但，语言文字是生活的再现，语文教学是引导学生通过文本学习达到对生活的感悟与升华。从而内化为自己的行为。
因此我做了如下设计：紧扣课题，引导学生回归整体；理解课题的内涵，进一步激发学生的情感；联系实际，从身边的人群中提升。
首先，我引导学生思考：“同学们，作者看的仅仅是雀吗？他还看到了什么呢？”（原来作者是透过雀来看人，看的是生活中像麻雀一样生活的人，虽然很忙碌平庸，但依然快乐地生活着。）
接着，我又进一步引导学生联系生活实际谈体会，“我们身边有这样的人吗？”
当学生谈到身边的普通人时，我展示了一组生活中平凡人工作的画面，让学生静静地看，静静地思考，此时无声胜有声。
总结升华：同学们，这就是“忙碌而不羞愧，平庸而不自卑”的平凡人，他们踏踏实实地工作，本本分分地生活。透过这一扇窗户，我们感受到了作者对弱小生命的敬重！让我们怀着这份对生命的敬重和对生活的热爱，再读一次吧！——忙碌而不羞愧，平庸而不自卑
最后向大家说说我的板书设计：
13 隔窗看雀
忙碌而不羞愧，平庸而不自卑
我们都知道板书是微型的教案，结合教学内容，我围绕着“忙碌而不羞愧，平庸而不自卑”展开教学活动。因此 本节课的板书设计本着简洁、清晰、直观的原则，抓住中心句帮助学生理解，突破本文的重点，从而使学生体会到作为一个平凡的人也能活得充实快乐。
尊敬的各位评委：以上是我就《隔窗看雀》一文的教学构想。对于教学而言仅仅是硬设计，在本课具体的教学实施过程中，我将时时关注课堂，关注学生，捕捉课堂生成，将其作为新的教学资源为我的课堂增姿添彩。总之，力争做到：每一堂课，上的永远比说的好！
谢谢各位评委！！！
