初中数学冀教版八年级下册《正方形》说课稿
二、学习新知1.正方形的定义在这一环节中，学生很容易犯的一个错误就是条件重复。这时我会引导学生从画图入手，提示他们：你能不能减少条件画出正方形呢？这一环节中我的观点是正方形的定义不是唯一的。我们可以从不同的角度来总结，只要合理就加以肯定。比如当学生总结出：四个角都是直角，四条边都相等的四边形是正方形。这时可以提醒学生是不是一定要四条边都相等，减少边的条数可以画出来吗？角的个数可以减少吗？鼓励学生动手试一试。通过动手画图可以很容易的得到正方形的一个定义：三个角都是直角，一组邻边都相等的四边形是正方形。通过小组讨论的形式来完成这一环节的设置。鼓励学生利用现有的材料继续构造正方形。从另一个角度总结正方形的定义。
《画》说课稿
（坚持以读为本，让学生真正成为语文课堂的“读者”，通过自由读、分组读、指名读、教师引读等多形式的朗读，引导学生图文对照，感悟诗句的内容和表达的感情。另外，文中句子的节奏感很强，朗读时指导学生读出诗的节奏和韵味，在读中感悟、体会诗的读法，想象诗中描绘的美好画面，感受画的美，语言文字的美，激发学生对祖国语言文字的热爱之情。）
《敕勒歌》说课稿
动静结合。诗的前六句是静态的勾画；“风吹草低见牛羊”，这句是动态的描写。风吹草低，这一现啊，不仅现出了牛羊，还现出了草原的灵动。色彩的丰富，画面的灵动，使敕勒川变得更加美丽。

《水》说课稿
2、活动目标：在新《纲要》中指出，五大领域的内容相互渗透，从不同的角度促进幼儿情感、态度、能力、知识、技能等方面的发展，因此，根据幼儿的年龄特点和实际情况，我制定了以下三个方面的目标：（1）知道有水的瓶子中加入石子和沙子可以使水位升高。（重点）（2）通过积极探索，发现乌鸦能否喝到水与水量的多少及加入的物体大小有系。（难点）（3）学习两人合作探索，体验与同伴合作学习、互相交流的乐趣。3、活动准备：根据《纲要》中指出的“提供丰富的可操作的材料，为每个幼儿都能运用多种感官、多种方式进行探索提供活动的条件。”我做了如下准备：（1）空间方面：教室四周放置操作的桌子。（2）物质方面：1、教具：不同水量的瓶子各一瓶，两只标有红、绿标志线的瓶子（绿标志线瓶子里的水多些，红标志瓶子里的水少些）学具：每组4只瓶子（两两一组，分别装有不通水量，贴不同颜色的标签），一盆小石子，一盆沙子、绿豆、黄豆等，小勺、漏斗若干。2、每组一块小抹布。3、展示台。4、fLAsH课件5、乌鸦喝水的故事经验。全方面的准备为活动的成功开展提供了保障。二、说教法在新《纲要》中指出，教师应成为幼儿学习活动的支持者、合作者、引导者，关注幼儿在活动中的表现和反应，敏感地察觉他们的需要，及时以适当的方式应答，形成合作探究式的师生互动。因此，我采用了以下教法：

二、说教学目标：1.学会本课生字。2.能正确、流利、有感情地朗读课文，背诵并默写课文。3.了解诗歌的大意，感悟诗人堂堂正正做人，清清白白生活的高尚情怀，领悟本课借物言志的表达方法。三、说教学重点、难点：指导学生有感情地朗读本首诗，感悟诗人堂堂正正做人，清清白白生活的高尚情怀，领悟本课借物言志的表达方法。四、说教学过程：（一）导入新课：同学们，你们读了那么多的书，老师考你们几个课外知识怎么样?1、“岁寒三友”是哪“三友”?2、你能背出有关“岁寒三友”的诗句吗?(指生背)今天，咱们一起来学习、欣赏王冕的千古佳作《墨梅》，读课题。
《盼》说课稿
1.会写12个生字,会写“雨衣、袖筒、斗篷”等词语。2.能把握课文内容,知道文章是通过哪些事例来写“盼”地。3.能找出文章哪些地方具体描写了“盼”这一心理活动,并能选择最生动地两处,说说这样写地好处。4.通过捕捉环境描写、人物地语言、动作、神态、心理、对话等描写,来感受小主人公情感地变化,体会童年生活地美好。三、说教学重难点1.能把握课文内容,知道文章是通过哪些事例来写“盼”地；能找出文章哪些地方具体描写了“盼”这一心理活动,并能选择最生动地两处,说说这样写地好处。2.通过捕捉环境描写、人物地语言、动作、神态、心理、对话等描写,来感受小主人公情感地变化,体会童年生活地美好。
《桥》说课稿
一、说教学目标?1.会写“咆、哮”等8个生字，正确读写“咆哮、沙哑、呻吟”等词语。? 2.正确、流利、有感情地朗读课文，理解课文内容，体会文章的思想感情，领悟课文在表达上的特点。?3.在读中感受老支书舍己为人的精神品质，感受他崇高的人格魅力。??三、说教学重难点1.抓住人物言行感受老汉的高贵品质和人格魅力。2.理解题目所蕴含的深刻含义是本课的教学难点。3.了解课文布局谋篇、人物刻画、环境描写等表达方面的特点。?四、说教法、学法? 六年级的学生已具备一定的研究性阅读和感悟的能力，能够在老师的引导下，掌握基本的阅读方法，读、思、记课文中需要重点领悟的部分。这篇课文篇幅短小，但文本所描绘的人物形象和场景都远离学生的生活实际，学生较难被文中老汉的形象、精神所打动，特别是对文章以“桥”为题的理解。为突破教学的重难点，我计划灵活运用多种教学方法进行优化组合。?1.情境教学法。让学生抓住文中一些渲染环境的词语和句子，想象面对死亡威胁的情景，切实感受当时的生命垂危，从而更好地理解老支书的舍己救人、忠于职守的高贵品质。?2.朗读法。叶圣陶老先生认为语文教学最基本最好的方法就是读，朱熹也说过“读书百遍，其义自见”，本篇课文语言简练，人物语言的刻画也很有表现力。让学生用多种形式的读，达到“以读代讲”“以读悟情”“以读达情”的效果。通过朗读、感悟、交流，让学生领会课题“桥”不仅仅是那座窄窄的木桥，更是老支书用自己的身躯架起的生命之桥！
人教版高中语文必修2《就任北京大学校长之演说》说课稿3篇
（三）教学重、难点1、教学重点：结合课文，了解演讲辞针对性强、条理清楚、通俗易懂、适当的感情色彩等特点。2、教学难点：深入理解文章内涵，联系现实，体会本文的现实意义二、说学情高中学生在初中阶段已经接触过演讲辞了，对演讲词的特点已经有了一些基本的知识，因此本轮的教学应该让他们在此基础上有所提高。本文是学生在高中阶段第一次接触演讲辞，有必要让他们了解演讲辞的特点及课文如何体现这些特点的。随着年龄的增长，生活阅历的增加，高中学生正逐渐形成自己对世界、对人生的看法，蔡元培先生的这篇文章能很好地激发他们对当前的高中学习和未来的大学生活进行思考。此外，学生对北大的历史及蔡元培先生作这番演讲的时代背景了解不深，应作出补充说明。
