部编人教版五年级下册《清贫》说课稿
三、说学情：本课领会方志敏同志清正廉洁这一美德并不困难。但是学生的生活阔别了贫苦，在明白“贫苦”对于革命的意义还会有些空洞化、观点化，这将成为学生学习课文的难点。四、说教法和学法：1.说教法：小组讨论法：针对老师提出的题目，学生举行分组讨论，促使学生在相助中解决题目，培养学生联合协作的能力。朗读感悟法：朗读是一种非常重要的教学要领，课文中方志敏与“士兵”的对话内容以及感情变革写得非常好，很得当，分脚色朗读，在朗读中感觉方志敏同道甘于贫苦、矜持不苟的崇高革命情操。2.说学法：高年级的学生应注意培养学生的自学本领，送还学生自主学习权，我引导学生利用以下要领进行学习：自主探究法、分析归纳法、总结反思法。通过题目导学、学法引导、知识总结等引导学生在课堂上积极学习。
部编人教版五年级下册《手指》说课稿
非常清楚，共有6个自然段，第一个自然段是总写手指的特点，2——5自然段是分写五个手指的不同特点，最后一个自然段又总写，点明了文章的中心。文章的语言朴实又富有风趣，采用了拟人化的手法将手指的不同特点写得淋漓尽致。这样的写作顺序及写作方法是学生学习的一个重点。这是一篇略读课文，可用一个课时完成教学。根据以上教材的特点以及新课标所特别关注的学生的“情感态度与价值观、过程与方法、知识与能力”这三个维度的理念，我制定了以下教学目标：1、会读带有拼音的生词，能联系上下文理解词语“窈窕、堂皇、渺小、附庸、养尊处优”的意思;2、能正确、流利、有感情地朗读课文，了解五根手指的不同特点，了解作者描写手指的写作顺序及写作方法。这也是本文的教学重点。3、体会到任何事物都各有所长各有所短的道理，以及团结合作的重要性;这也是本文的教学难点。
部编人教版五年级下册《跳水》说课稿
一、说教材《跳水》是小学语文五年级下册的一篇精读课文。训练主题是:①抓住文章中的重点词句,体会其表达效果。②揣摩文章表达的顺序，学习基本的表达方法。本单元训练主题与各单元文化主题的融合:抓关键词句，品读文字中的生活，感受生活中智慧的灵光。《跳水》讲述了发生在一艘外国帆船上发生的事. 一只猴子把船长儿子戴的帽子挂到了桅杆顶端最高的横木一头，孩子为了追回帽子,走上橫木，在万分危急的时刻船长急中生智,命令儿子跳水,使孩子转危为安。教材的编排意图是:在读懂课文的基础上,学习船长在危急中,冷静机智和果断处理问题的方法和了解作者记叙一件事情经过的方法。本篇课文情节惊险,扣人心弦，易于激起小学生的阅读兴趣,形象逼真的教材插图给人以身临其境之感。
人教版高中语文必修2《采薇》说课稿
三、疏通课文，体会情感学生朗读一至三节，找出通假字，如“莫”；语助词如“止”“曰”；古今异义词如“启”“居”。以及个别短语如“靡室靡家”“载饥载渴”的结构，结合上《卫风·氓》中出现的相同或类似的结构来理解。检查学生的自学情况，抽查翻译，纠正错误。这三节都以采薇起笔，让学生思考课文呢写了薇菜生长的哪几种形态，有什么作用？学生思考。这个问题不难，但学生回答可能不完整，只点到用于表达士卒思归之情的强烈。老师要补充，用薇菜的生长来反映归期的推移和不定期，思念之情更加沉重。同时在艺术手法上，同《卫风·氓》用“桑叶”来起兴一样，这里也是比兴手法，引出下文。另外，战士们靠野菜来充饥也反映了战士们生活艰苦，兴中有赋。
人教A版高中数学必修二平面与平面垂直教学设计
6. 例二：如图，AB是⊙O的直径，PA垂直于⊙O所在的平面，C是圆周上的一点，且PA＝AC，求二面角P－BC－A的大小． 解：由已知PA⊥平面ABC，BC在平面ABC内∴PA⊥BC∵AB是⊙O的直径，且点C在圆周上，∴AC⊥BC又∵PA∩AC=A,PA,AC在平面PAC内，∴BC⊥平面PAC又PC在平面PAC内，∴PC⊥BC又∵BC是二面角P-BC-A的棱，∴∠PCA是二面角P-BC-A的平面角由PA=AC知△PAC是等腰直角三角形∴∠PCA=45°，即二面角P-BC-A的大小是45°7.面面垂直定义一般地，两个平面相交，如果它们所成的二面角是直二面角，就说这两个平面互相垂直，平面α与β垂直，记作α⊥β8. 探究：建筑工人在砌墙时，常用铅锤来检测所砌的墙面与地面是否垂直，如果系有铅锤的细绳紧贴墙面，工人师傅被认为墙面垂直于地面，否则他就认为墙面不垂直于地面，这种方法说明了什么道理？
人教A版高中数学必修一充分条件与必要条件教学设计（1）
本课是高中数学第一章第4节，充要条件是中学数学中最重要的数学概念之一， 它主要讨论了命题的条件与结论之间的逻辑关系,目的是为今后的数学学习特别是数学推理的学习打下基础。从学生学习的角度看，与旧教材相比，教学时间的前置，造成学生在学习充要条件这一概念时的知识储备不够丰富，逻辑思维能力的训练不够充分，这也为教师的教学带来一定的困难．“充要条件”这一节介绍了充分条件,必要条件和充要条件三个概念,由于这些概念比较抽象,中学生不易理解,用它们去解决具体问题则更为困难,因此”充要条件”的教学成为中学数学的难点之一,而必要条件的定义又是本节内容的难点.A.正确理解充分不必要条件、必要不充分条件、充要条件的概念；B.会判断命题的充分条件、必要条件、充要条件．C.通过学习，使学生明白对条件的判定应该归结为判断命题的真假.D.在观察和思考中，在解题和证明题中，培养学生思维能力的严密性品质．
人教A版高中数学必修二立体图形直观图教学设计
1.直观图：表示空间几何图形的平面图形，叫做空间图形的直观图直观图往往与立体图形的真实形状不完全相同，直观图通常是在平行投影下得到的平面图形2.给出直观图的画法斜二侧画法观察：矩形窗户在阳光照射下留在地面上的影子是什么形状？眺望远处成块的农田，矩形的农田在我们眼里又是什么形状呢？3. 给出斜二测具体步骤（1）在已知图形中取互相垂直的X轴Y轴，两轴相交于O，画直观图时，把他们画成对应的X'轴与Y'轴，两轴交于O'。且使∠X'O'Y'=45°（或135°）。他们确定的平面表示水平面。（2）已知图形中平行于X轴或y轴的线段，在直观图中分别画成平行于X'轴或y'轴的线段。（3）已知图形中平行于X轴的线段，在直观图中保持原长度不变，平行于Y轴的线段，在直观图中长度为原来一半。4.对斜二测方法进行举例：对于平面多边形，我们常用斜二测画法画出他们的直观图。如图 A'B'C'D'就是利用斜二测画出的水平放置的正方形ABCD的直观图。其中横向线段A'B'=AB，C'D'=CD；纵向线段A'D'=1/2AD，B'C'=1/2BC；∠D'A'B'=45°，这与我们的直观观察是一致的。5.例一：用斜二测画法画水平放置的六边形的直观图(1)在六边形ABCDEF中，取AD所在直线为X轴，对称轴MN所在直线为Y轴，两轴交于O'，使∠X'oy'=45°（2）以o'为中心，在X'上取A'D'=AD，在y'轴上取M'N'=½MN。以点N为中心，画B'C'平行于X'轴，并且等于BC；再以M'为中心，画E'F'平行于X‘轴并且等于EF。 （3）连接A'B',C'D',E'F',F'A',并擦去辅助线x轴y轴，便获得正六边形ABCDEF水平放置的直观图A'B'C'D'E'F' 6. 平面图形的斜二测画法（1）建两个坐标系，注意斜坐标系夹角为45°或135°；（2）与坐标轴平行或重合的线段保持平行或重合；（3）水平线段等长，竖直线段减半；（4）整理.简言之：“横不变，竖减半，平行、重合不改变。”
人教A版高中数学必修二平面与平面平行教学设计
1.探究：根据基本事实的推论2,3，过两条平行直线或两条相交直线，有且只有一个平面，由此可以想到，如果一个平面内有两条相交或平行直线都与另一个平面平行，是否就能使这两个平面平行？如图（1），a和b分别是矩形硬纸板的两条对边所在直线，它们都和桌面平行，那么硬纸板和桌面平行吗？如图（2），c和d分别是三角尺相邻两边所在直线，它们都和桌面平行，那么三角尺与桌面平行吗？2.如果一个平面内有两条平行直线与另一个平面平行，这两个平面不一定平行。我们借助长方体模型来说明。如图，在平面A’ADD’内画一条与AA’平行的直线EF,显然AA’与EF都平行于平面DD’CC’,但这两条平行直线所在平面AA’DD’与平面DD’CC’相交。3.如果一个平面内有两条相交直线与另一个平面平行，这两个平面是平行的，如图，平面ABCD内两条相交直线A’C’,B’D’平行。
人教A版高中数学必修二直线与平面垂直教学设计
1.观察（1）如图，在阳光下观察直立于地面的旗杆AB及它在地面影子BC,旗杆所在直线与影子所在直线的位置关系是什么？（2）随着时间的变化，影子BC的位置在不断的变化，旗杆所在直线AB与其影子B’C’所在直线是否保持垂直？经观察我们知道AB与BC永远垂直，也就是AB垂直于地面上所有过点B的直线。而不过点B的直线在地面内总是能找到过点B的直线与之平行。因此AB与地面上所有直线均垂直。一般地，如果一条直线与一个平面α内所有直线均垂直，我们就说l垂直α，记作l⊥α。2.定义：①文字叙述：如果直线l与平面α内的所有 直线都垂直，就说直线l与平面α互相垂直，记作l⊥α.直线l叫做平面α的垂线，平面α叫做直线l的垂面．直线与平面垂直时，它们唯一的公共点P叫做交点．②图形语言：如图．画直线l与平面α垂直时，通常把直线画成与表示平面的平行四边形的一边垂直．③符号语言：任意a?α，都有l⊥a?l⊥α.

关于小学教师个人教学心得体会优选八篇
作为一一名任课教师，我们或许都有过这样的体验，每当上完一节好课，会让你有意犹未尽之感，全身都会感到舒爽之至。而往往公开课更容易达到这样的境界。想想为什么，一个很重要的原因就是我们无形中做到了“懂”、“透”、“化”。 总之，我们在处理教材上真正做到“懂”、“透”、“化”，真正做到“钻进去，走出来”，就会达到创设教材研究的理想境界。
中班科学《找数字》说课稿
根据中班幼儿的年龄特点，他们对数字非常感兴趣，对周围事物充满好奇心。而且，数字的概念是抽象的，对于幼儿来说，数字的认识应强调多感官参与。因此，我选择了这个活动，主要是让幼儿能通过观察寻找、动手操作的过程中积极思考，以及灵活运用周围环境中的数字让幼儿在玩中学，促进幼儿对周围生活中的数字与生活密切相连。根据幼儿的认知理解水平，我认为本次活动的重点与难点应归结为：在活动中理解数字在不同的物体的用处，同时对周围生活中数字感兴趣。
幼儿园大班数学说课稿
以幼儿在第一课时的学习情况及布卢姆的《教育目标分类学》为依据，我从认知、能力、情感方面确立了本节课的目标： (1)幼儿通过游戏能较熟练地分辩10以内的单数、双数。 (2)培养幼儿思维的灵活性，提高幼儿在数学活动中的分析 (3)幼儿在游戏中体验参加数学活动的乐趣。 判断能力。 根据目标，我把活动的重点定位于：幼儿在游戏中通过亲自操作，能作证明10以内的任意一数是单数还是双数。 活动的难点是：幼儿能根据单双数的排序规律，成功地解决游戏中的一些问题。 为了在游戏中充分调动幼儿的各种感官参与活动，我准备了充足的材料：数字卡片、实物教具、磁性黑板、胸卡、头饰等：此外，富有挑战性的游戏还要求幼儿有相关的知识准备，如：掌握序数、相邻数等。
李商隐诗两首教学设计
《锦瑟》的主旨颇多，悼亡、恋情、自伤身世，每一种都有其支持者的长篇论述，但其首联中“一弦一柱思华年。”从这个角度来看，似乎将主题定调为对“华年”的追思，似乎更为妥帖。当我们有了一个明确的基调之后，后面几联在解读时就有了一个准确的方向。
新人教版高中英语必修3Unit 1 Festivals and Celebrations-Reading for writing教学设计二
Step 3 Analyzing article structureActivity 31. Teachers raise questions to guide students to analyze the chapter structure of this diary and think about how to describe the festival experience. (1)What should be included in the opening/body/closing paragraph(s)?(2)How did the writer arrange his/her ideas?(3)What kind of interesting details did the writer describe?(4)How did the writer describe his/her feelings/emotions during the event?2. Students read and compare the three sentence patterns in activity 2. Try to rewrite the first paragraph of the diary with these three sentence patterns. After that, students exchange corrections with their partners. Such as:●This was my first time spending three days experiencing the Naadam Festival in China’s Inner Mongolia Autonomous Region and it was an enjoyable and exciting experience. ●I'll never forget my experience at the Naadam Festival because it was my first time to watch the exciting Mongolian games of horse racing, wrestling, and archery so closely. ●I'll always remember my first experience at the Naadam Festival in China’s Inner Mongolia Autonomous Region because it was so amazing to spend three days witnessing a grand Mongolian ceremony. Step 4 Accumulation of statementsActivity 41. Ask the students to read the diary again. Look for sentences that express feelings and emotions, especially those with the -ing form and the past participle. Such as:● …horse racing, wrestling, and archery, which are all so exciting to watch. ● some amazing performances● I was surprised to see…● I was a little worried about. . . ● feeling really tiredOther emotional statements:●I absolutely enjoyed the archery, too, but the horse races were my favourite part. ●I'm finally back home now, feeling really tired, but celebrating Naadam with my friend was totally worth it. ●He invited me back for the winter to stay in a traditional Mongolian tent and cat hot pot. I can’t wait!2. In addition to the use of the -ing form and the past participle, the teacher should guide the students in the appreciation of these statements, ask them to memorize them, and encourage them to use them reasonably in writing practice.

新人教版高中英语必修3Unit 4 Space Exploration-Listening&Speaking＆Talking教学设计二
The themes of this part are “Talk about how to become an astronaut” and “Talk about life in space”. As Neil Armstrong said “Mystery creates wonder and wonder is the basis of man’s desire to understand. Space is difficult for human to reach, therefore, humans are full of wonders about it. However, if wanting to achieve the dream of reaching the Moon, some of our human should work hard to be an astronaut at first. Part A(Talk about how to become an astronaut) is a radio interview in a radio studio, where the host asked the Chinese astronauts about his story how to become an astronaut. Yang Liwei told his dreamed to be an astronaut since childhood. Then he worked hard to get into college at 22. The next 10 years, he gradually became an experienced pilot. At the same time, to be an astronaut, he had to study hard English, science and astronomy and trained hard to keep in good physical and mental health and to practise using space equipment. Part B (Talk about life in space) is also an interview with the astronaut Brown, who is back on the earth. The host Max asked about his space life, such as his emotion about going back the earth, the eating, shower, brushing, hobbies and his work. Part A and Part B are interviews. So expressing curiosity about the guests’ past life is a communicative skill, which students should be guided to learn.1. Students can get detailed information about how Yang Liwei became an astronaut and Max’s space life.2. Students learn to proper listening strategy to get detailed information---listening for numbers and taking notes.3. Students can learn related sentences or phrases to express their curiosity like “ I wish to know...” “I’d love to know...”4. Students can learn more about the space and astronauts, even be interested in working hard to be an astronaut
