小学数学人教版五年级下册《因数和倍数》说课稿
二、教学目标分析新课标指出，教学目标应包括知识与技能，过程与方法，情感态度与价值观这三个方面，而这三个方面又是一个紧密联系的有机整体，学生学会知识与技能的过程同时成为学会学习，形成正确价值观的过程，这告诉我们，在教学中应以知识与技能为主线，渗透情感态度价值观，并把两者充分体现在过程与方法中。借此，我将三维目标进行整合，确定本节课的教学目标为：1、从操作活动中理解因数和倍数意义，掌握找一个数的因数和倍数的方法，会判断一个数是不是另一个数的因数或倍数。 2、培养学生抽象、概括的能力，渗透事物之间相互联系、相互依存的辩证唯物主义观点。 3、通过主动探究，合作交流，培养学生的合作意识、探索意识，以及热爱数学学习的情感。
小学数学人教版五年级下册《约分》说课稿

部编人教版三年级上册《古诗三首 望天门山》说课稿
一、说教材这首诗都描绘了祖国山川景色，抒发了赞美之情；《望天门山》头两句描写山川气势。“天门中断楚江开，碧水东流至此回。”第一句主要先写山，天门山似乎是由于水流的冲击而从中间豁然断开，江水从断口奔涌而出。第二句写水，浩浩荡荡的长江被天门山阻挡，激起滔天的波浪。第三、四句写行船的感受。坐在小船上迎着阳光顺流而下，感觉两岸青山相对而来。诗歌通过对天门山景象和内心体验的描述，赞美了大自然的神奇壮丽，表达了乐观豪迈的情感。二、说教学目标1.理解词义句意，培养学生丰富的想象力和语言表达能力。2.体会作者热爱祖国山水的感情，感受诗歌美的意境。3.掌握古诗的学习方法，培养学生的学习能力。4.能有感情地朗读和背诵全诗。三、说教学重难点1.引导学生体会感情，欣赏意境。（重点）2.引导学生理解难懂字词的意思，并通过词义理解达到理解全句、全篇的意思。（难点）
部编人教版三年级上册《卖火柴的小女孩》说课稿
（二）创设情境，初读感知 上课伊始，我和学生进行谈话，让学生回忆过除夕的情景，调动学生快乐的情感体验，在此基础上，出示卖火柴的小女孩图片，以充满感情的话语导入新课，把学生引入特定的情境。让孩子们除夕的快乐和小女孩在大年夜冻死街头的凄惨形成鲜明的对比，激起孩子们迫切想了解这个小女孩的强烈欲望，达到“课伊始趣已生”的效果。 接下来，我让孩子们静静地欣赏《卖火柴的小女孩》的动画，伴着哀伤的音乐，体会着画面中小女孩痛苦的神情，我相信整个班里都会回荡着悲伤的氛围。这种氛围的营造，为下面理解课文做了很好的情感铺垫。 然后，我让孩子们用自己的方式初读课文，畅谈感受。孩子们可能会说：她是一个可怜的孩子、贫穷的孩子、美丽的孩子，一个听话的孩子，一个孤独的孩子……叶澜教授曾指出：“没有沟通就不可能有教学”，在孩子们谈感受的过程中，老师一定要用眼神和表情来和学生产生情感的沟通，老师要充分尊重孩子独特的情感体验，不要给予是非评价，而是让孩子们自己在学习课文的过程中去不断地印证自已的感受。

二、说教学目标1.正确、流利、有感情地朗读这首诗。2.一边读一边展开想象，从秋天的声音中体会秋天的美好。3.尝试仿照诗歌的格式，续写诗文。三、说教学重难点1.从秋天的音响中，想象秋天景象的美好；有感情地朗读诗歌，体会诗中浓浓的秋情。?（重点） ?? 2.体会诗中浓浓的秋意，仿照诗歌的形式，说一说，写一写。（难点）四、说教法和学法教法：在本课的设计中，我以“美”为基调，以“赏”为主线，以“趣”为佐料，以“仿”为桥梁，旨在让学生久久沉浸在浓浓的诗情秋韵里，来丰富学生的情感体验，从而使语文学习变成一种愉悦身心的自主的渴望。学法：充分运用视频、音频等多媒体教学手段，调动学生多种感官参与教学，提高教学效率。让学生们从秋天所特有的声音中，体味秋天独特的风情。使学生初步接触诗歌，走进诗歌，感受诗歌从而达到热爱诗歌，进一步提高学生的语文素养。
（说课稿）部编人教版三年级下册《 昆虫备忘录》
一、说教材《昆虫备忘录》是统编小学语文三年级下册第一单元中的略读课文，文章抓住了蜻蜓、瓢虫、独角仙、蚂蚱的特点进行介绍，教给了人们知识，表达了对生灵的喜爱之情。本节课通过引领学生学习备忘录，让学生了解备忘录的书写及作用,并学会书写备忘录。利用备忘录来记录自己感兴趣的内容。二、说学情只有了解读者的阅读现状，才能充分发挥文本的魅力。经过了两年多的学习，学生已经积累了一些识字的经验，学习重点逐渐向阅读过渡，也掌握了一些阅读方法，如：朗读、默读；借助图画、生活实际，联系上下文理解词语等。但是孩子们对于事物的观察还远远不够，对于昆虫的了解更是少之又少，体会昆虫的可爱，是一个难题。三、说教学目标1.熟知字词句，有感情朗读课文，积累优美语句。2.学习作者观察描写事物的能力。3.感受这四种昆虫的特点，培养热爱生灵的思想感情。
