《黄河的治理》是人教版八年级上册第二章《中国的自然环境》第三节《河流》的第二课时的教学内容。教材上承中国自然环境的位置、地形、气候，下启中国生态环境问题突出的黄土高原。黄河是中华民族的摇篮，是我国第二长河，被称为母亲河。了解黄河的基础知识，感受黄河的母亲情怀，感同身受的去感知黄河的忧患意思和治理策略。通过本课的学习，探究出黄河的忧患及治理措施，同时帮助学生树立爱国主义情感，对培养学生从小养成节约用水的良好习惯是有益的，与学生的实际生活联系很密切。真正可以做到从生活中学习地理，学习对生活有用的地理。
本节课是初二的地理教材，对学生的情况作如下四个方面的分析：
1、知识掌握上，经过前面的学习，学生对于河流的学习方法有一定了解，知道应该从哪几个方面入手去掌握，而黄河这一特殊的河流有较生疏，因此要想办法去激发学生的学习兴趣。
2、心理上，学生对于地理课有一定的厌倦的心理，不掌握学习的方法，教师在教学中要注意运用多种教学手段去吸引学生。
3、生理上，青少年好动，注意力易分散，爱表现自己，教师在学中应抓住这一生理特点，一方面采取多种直观的手段，引发学生的学习兴趣，使学生的注意力始终集中在课堂上，另一方面加强双边活动，创造多种机会和条件，让学生参与进来，发挥学生学习的主动性。
4、学生学习本节课的知识障碍。学生学习本节课将遇到一些知识障碍，如：黄河地上河的成因，黄河的奉献与危害这两个截然相反的特征等不易理解，所以在教学中，教师应予以简单明了，深入浅出的分析。
1、知识与技能目标：读图说出黄河的发源地、流经省区、注入的海洋、长度和上中下游的分界点。
2、过程和方法目标：培养学生读图用图能力，学会用地图等资料，说明黄河的基本概况；能解释黄河各河段产生灾害的原因以及治理的基本方法，从而培养学生的创造性思维能力；提高学生收集整理分析地理信息的能力。
3、情感态度与价值观目标：通过分析黄河作为我国的“母亲河”为中华民族的发展作出的贡献，培养学生的民族自豪感和民族自信心，唤起学生对治理黄河、保护黄河的责任感，并逐步树立人地协调观念及可持续发展的观念。
教学重点：分析黄河为中华民族所做出的贡献及带来的灾难，了解黄河当前所面临的问题，探究黄河治理方案。
教学难点：运用有关资料和已有知识储备，探究黄河所产生问题的原因
1、探究式教学：在教学中，营造宽松和谐的课堂氛围，激励学生在解决问题中探究，有利于激发学生学习地理的积极性、主动性，培养学生的创新精神和地理实践能力。
2、小组合作学习：这种方式既有利于培养学生的合作学习意识，又能增强学生竞争意识，提高参与各种活动的积极性，促进全体学生的共同发展。
3、多媒体教学：多媒体课件，将文字、图形等媒体综合在一起，创设直观性与探索性相结合的教学情境，以强化学生的主体作用，提高课堂教学效率。
1、学会用图：培养学生从各种地理图像中获取地理信息的能力。
2、学会探究：使学生在探究性学习中，掌握比较、分析综合等科学的探究方法。
3、学会合作：通过小组讨论，培养学生的互动能力，使学生学会合作学习。4、学会归纳：要求学生在地理学习过程中逐渐养成概括归纳的意识，并能用准确简练的语言表达某一问题的含义。
导入新课：李白的名句：君不见，黄河之水天上来，奔流到海不复回。大家都耳熟能详，殊不知，李白却犯了两个常识性的错误，首先，黄河之水并不是天上来，奔流到海也不是不复回。（简要介绍水循环，为高中地理学习打下伏笔）。要想知道黄河之水哪里来，又流到哪里去？就要来好好学习《黄河》之一部分内容。
设计意图：幽默的语句，使学生马上进入课堂情景，欲擒故纵，调动学生的求知欲。
一、了解母亲河 步骤：
要求学生读“黄河流域水系图”，并配合“中国地形图”和“中国政区图”，沿源头到入海口依次找出黄河的发源地、沿途所经过的支流、地形区、省级行政区及上中下游的分界点河口、旧孟津。各小组充分讨论后，派代表回答，并填绘到练习本上。
设计意图：培养学生搜集整理信息的能力及锻炼他们语言表达能力，提高学生的读图能力，建立空间观念，使学生对黄河有一个整体上的认识。
二、母亲河的奉献
本课的重点虽然不在这里，但可树立辨证唯物主义观念和进行爱国主义教育。
为什么把黄河比做母亲？
步骤： 1、教师出示“黄河流域水系图”，宁夏平原的景观图片，壶口瀑布照片等。
2、各小组讨论，得出问题的答案后，
进行完这个活动，此时同学们对母亲河的奉献，有了初步的感受。
教师适时总结：黄河，曾无私养育了两岸的人们。但如今，却成了世界上最难治理的一条河流，历史上给人们带来了无尽的灾难。
三、 母亲河的忧患：
这部分内容是本课的一个重点，采用读图分析——发现问题——启发引导——主动探究的思路来完成的。
1. 多媒体显示：“黄河的忧患”图片，学生仔细观察图，结合资料，教师提出问题：“黄河忧患在上、中、下游各有哪些表现？”允许学生大胆回答，教师再设疑：说一说造成黄河忧患不断的自然和人为因素各有哪些？这些因素可能产生什么影响？学生回答过程中，教师适时启发、引导进而得出答案。
2. 然后课件演示黄河“地上河”的形成过程，学生突破思维定势，自然而然说出“地上河”的形成与中游的水土流失有什么关系及“地上河”有什么危害？
情况预测：这个活动，以学生探究为主，鼓励学生发挥想象，扩展思维，主动回答，有的同学可能回答不准确，教师根据学生回答给予引导、帮助，适时总结。
设计意图：以上活动，利于培养学生获取图文信息能力，推理分析的思维能力及解决实际问题的应用和创新能力，增强环境保护意识和可持续发展观念。
四、母亲河的治理：
通过以上活动，我们分析了黄河带来的忧患及形成的原因，那么如何治理黄河这个问题就呈现在眼前了，为了突破这一教学重点，我采用了“角色扮演法”来完成。我是这样设计的：“同学们，母亲现在多灾多难，做儿女的怎能袖手旁观呢？”
角色扮演：“假如让你来治理黄河，该们么做呢？”学生献计献策。 教师展示：“引黄淤灌图” 及上、中、下游的治理措施（上游：梯级开发，兴修水利；中游：保持水土，植树造林；下游：固堤分流）。
然后观看图片，介绍“保护母亲河行动”及新中国成立以来治理黄河所取得的伟大成就。使学生理解协调人地关系的重要性。
设计意图：角色扮演，让学生亲自感悟，亲身实践，一方面极大地调动了学习主动性、参与性；另一方面增强社会责任感。
九、说作业
1、把本节课知识点总结成知识树。
2、作为中学生可以为治理黄河做什么工作？
说课稿数学篇二
我将从教学依据、教法学法、教学过程、教学反思四个方面，谈一谈我对本节课的教学设计。
1.教材内容及地位分析
我对比了江苏教育出版社和河南科技出版社两个版本的教材，这一节都是技术与设计2第四章第二节的内容。《控制及其设计》这一章是在必修一中学习了技术设计的一般思想和方法以及学习了必修二结构、流程、系统等知识之后的综合运用，这些知识在生产和日常生活中有广泛的应用，与现代科学技术紧密相关，而《开环控制系统和闭环控制系统》一节是本章的重要基础，为下一节理解闭环控制系统的干扰与反馈打下基础，为最终完成控制及其设计做铺垫。通过学习也有助于学生今后运用简单的控制方法解决现实生活中遇到的相关问题，发展学生良好的思维品质。
2.课程标准
我们倡导基于课程标准的教学设计。与本节课相关的课程标准是：“分析典型的案例，了解手动控制、自动控制，熟悉简单的开环控制系 统和闭环控制系统的基本组成和简单的工作过程。”
在这句话中手动控制、自动控制在第一节中已经讲到，要达到熟悉开环控制系统和闭环控制系统的基本组成首先需要对它们进行辨别，而辨别的依据是有无反馈，这恰好是学生难以掌握的地方，所以计划用1课时重点突破，将工作过程和画出方框图放在第2课时处理。
3.课时安排
本节课时安排为：第1课时主要了解开环控制系统和闭环控制系统的差异，会辨别简单的开环控制系统和闭环控制系统；第2课时主要了解开环控制系统和闭环控制系统的工作过程，并会用方框图来表示。本节课是第1课时。
4.学情分析
（1）学生基础：我校通用技术课程规划将<机器人简易制作>作为教学载体，融入到必修一和必修二的教学中，在学习到本章时学生对机器人已有较完整的认识，可以自己编写设计程序。通过上一节课的学习,学生对控制的概念也有基本的认识。
（2）学习目标：在这一节，学生通过体验机器人的开环控制和闭环控制，进一步探究控制系统，分析开环控制系统与闭环控制系统的差异，引出反馈的概念，为控制系统的设计与实施奠定基础。
（3）教学策略：通过师生互动，合理引导，实践、体验、探究、交流、多媒体等方法，使学生达到本节内容的学习目标。
5.教学目标
（1）知识与技能：初步掌握简单的开环控制系统和闭环控制系统的概念和区别。
（2）过程与方法：通过实验观察和实践体验，渗透控制的思想和方法，使学生了解开环控制系统和闭环控制系统的辨别方法。
（3）情感、态度、价值观：通过视频、实验、案例、体验等一系列活动，领略控制系统的奇妙，激发探索控制系统的兴趣，在体验性学习过程中，培养细心观察和相互交流的学习习惯与合作精神，提高学生的技术素养。
5.教学重点难点
教学重点： （1）开环控制系统和闭环控制系统的案例分析。
（2）开环控制系统和闭环控制系统的辨别。
教学难点：对开环控制系统和闭环控制系统的辨别。
1.教学设计基本框架
2.本节课设计思路
联想质疑—案例分析—归纳概括—迁移应用—实践创新—交流评价—课堂小结—布置作业
概括起来就是:
这样做是为了引导学生从技术的视角观察生活，用技术的概念建构双基，并将技术再应用到生活中去，以此培养学生的技术素养，实现技术教育的总目标。
这就要求我们在教学设计中将生活线索、问题线索、知识线索、实践线索、方法线索等融会贯通，整合在一起。
3.主要教法
问题教学法；探究式教学法；案例分析法；实验演示法。
4.主要学法
以探究式学习方法为主，采用小组合作探究的形式。

综上所述，在本节课中共提出3个递进问题，进行了4项学生探究活动，前后共分析了8个案例，演示了一个实验，布置了2个拓展延伸。
这节课我反复思考，也有过困惑。如：对知识和技能度的把握；对学生在给定时间内能不能自主完成实践任务也有担心。然而随着课堂教学目标的有效达成，使我坚信这种课型模式是成功的，能有效提高学生技术素养。只要我们相信自己的学生，让他们成为课堂的主体，他们就一定能从自主探究和实践中体会到技术带来的乐趣！
谢谢各位，敬请指导！
说课稿数学篇三
1、地位、作用：
《垃圾的回收利用》是教科版六年级下册“环境和我们”教学单元第四课内容。本单元的`课程编排是建立在前几册已经学习的“资料”“空气和我们的生活”以和“生物与环境”等环境教育内容的基础上，引领同学从地球整体的环境问题入手展开调查研究，本课《垃圾的回收利用》是本单元教学内容的一个重点，教材的编写意图是通过最贴近同学生活实际的垃圾问题入手展开调查、收集、分类等体验活动，以此为突破口来引发同学对整个人类面临的环境问题的考虑，培养同学的环保意识和资源意识。让同学认清解决垃圾问题的重要性和紧迫性。为后面《考察家乡的环境》和《我们的环保行动》打下基础，使《课标》中关于环境教育的要求得到全面落实。
本课探究活动主要分为两个局部。
第一局部：研讨垃圾回收利用的好处
要求同学按小组收集资料，向大家介绍回收利用某种资料带来的好处，然后我再把一些数据资料展示给同学，让同学在阅读中感受回收资料带来的好处，同时认识回收标志，同学在认识回收资料的好处后，再让同学分组体验垃圾资料的回收分类过程。提高同学对垃圾回收意义的认识。
第二局部：研讨建立一个资源回收中心。
同学在体验分类回收过程中，知道了我们日常生活中可回收的垃圾资料不外乎有玻璃、金属、纸张和塑料等这几大类，要建立班级回收中心，首先让同学明白作好哪些准备，然后引导同学从回收箱的设计、放置位置、谁来管理等问题展开讨论，最后达成共识，形成一个完整的回收中心方案。鼓励同学课后去实施这套方案。然后再引导同学研讨回收的资源如何处置等问题。在同学心目中建立起一套完整的解决垃圾问题的方案。
根据教材的编写意图，结合六年级同学实际，遵循课标精神，我确定了以下教学目标。
1、知识目标：经历一个垃圾的回收分类过程，认识可回收利用的资料，了解一些常见的可回收资料的分类方法。认识回收标志，
2、能力目标：经历各种途径查阅、收集资料，了解垃圾回收利用的好处，培养收集、处置信息的能力。
3、情感目标：通过了解垃圾回收利用的好处，从而树立正确的价值观，培养资源意识。
教学重点：
引导同学学会垃圾的分类方法，制定建一座回收中心的方案。
教学难点：
讨论制定建一座回收中心的方案。
教学准备：
同学：带一些平时会扔掉、但可以回收利用的物品。调查物品回收利用的好处
老师：有回收标志的不同品种的塑料瓶，回收垃圾的有关图片和课件。
教学流程：
创设情景导入课题―了解回收好处发生回收动机－讨论回收方法体验回收过程－借鉴回收体验组建回收中心－通过方案讨论发现利用价值－总结拓展。
本课教学对象是六年级同学，经过三年半的科学学习，具备了一定的观察能力、探究能力和合作学习的能力。他们活泼开朗，喜欢质疑。具有良好的科学素养，师生关系融洽。但在语言表述方面有点欠强，需要在课堂教学中合理的引导，逐步提高语言表达能力。
1、教法：科学教学力争在教给同学知识的同时，培养同学获取知识的方法和能力，才干使他们受益无穷。因此，结合同学实际和教学内容，我采用科学教学中最常用的探究式教学法，组织同学经历“解决垃圾问题”的一个完整的科学探究过程，并在组织教学过程中适当创设一些教学情境，交叉一些讲解、示范、点拨、启发、评价等手段，力求通过学习、体验垃圾的回收分类过程，从而获得一整套科学的学习方法，提高同学的科学素养，激发同学学科学、爱科学的情感。
2、学法：与教法相适应，充沛发挥同学的主体作用，让同学分组实验，小组合作交流集思广益，思维互补，充沛体现“以同学为主体，以探究为核心”的教学理念。
为了完成以上教学目标，我把教学内容分为6个层面递进展开：1、情景导入，引出课题。2、研讨回收好处，激发回收动机。3、研讨回收方法，体验回收过程。4、借鉴回收体验组建回收中心。5、讨论回收资料的处置，了解资料加工再利用流程。6总结、拓展谈体会。
1、情景导入，引出课题：
好的开头是胜利的一半，恰当的导入能激发同学的兴趣，为新课教学发明最佳的学习氛围。教学一开始，我先创设第一个情景，示两张城市街道图(一张卫生城市，一张垃圾城市)。让同学从中选择一座城市来生活，同学选择了卫生城市，并说明理由。接着设疑：这座城市的垃圾都到哪去了呢？引出垃圾问题，同学猜测，引发探究欲望。接着创设第二个情景，带领同学到垃圾填埋场去看看，同学到了垃圾填埋场后发现，这座卫生城市的垃圾不但没有填埋，而且是露天堆放的。引发怎么解决这些垃圾问题的考虑。引出本课的探究主题《垃圾的回收利用》进入第二个教学环节。
2、研讨回收好处，激发回收动机：
接着引导同学观察这堆垃圾里有些什么资料？回收这些资料有多大的价值？让同学举例说明，然后我就出示一些数据资料，让同学从阅读这些资料中了解了到回收这些资料会发生这么大的经济价值。因而发生回收这些资料的欲望。同学有了回收欲望，但不知从何着手，引发问题考虑：“怎么回收”由此进入第三个教学环节。
3、研讨回收方法，体验回收过程：
投影出示“怎么回收”同学经过一番考虑后，得出各种不同的回收方法。然后指导同学汇报方法，这时我巧妙利用同学思维的多样性进行比较，让同学在对比中发现自身的缺乏，从而找出一种比较科学的分类回收方法。同学找到科学的分类方法后必定想体验一下这种方法可信度。接下来我就布置了一个实物分类回收的体验活动。然后组织同学进行小组分类竞赛，并上台汇报分类活动中遇到的困难和问题。合理的引导和展示同学的思维过程。最后归纳总结出生活中可回收资料不外乎有玻璃、金属、纸张和塑料等这几大类。有了这样一个体验以后，同学基本上掌握了垃圾资料的回收方法。接下来就要把这种方法应用到实际的生活中。引出下一个教学环节。
4、建立班级回收中心：
在这一环节的教学中，我首先让同学回忆一下班上每天都会发生哪些垃圾，要回收这些垃圾资料我们应该做好哪些准备？然后再让各小组讨论如何组建这个回收中心。并投影出示在讨论中关注的几个问题。同学讨论完成后，上台汇报设计的方案。让全班同学作评判，最后达成共识，形成一个完整的回收中心方案。褒扬设计好的小组。鼓励同学课后去实施这套方案。有了完整的方案以后，新的问题又出现了。提出问题：回收这些资料以后如何处置？引出下一个教学环节。
5、回收资料的加工再利用：
这一教学环节我是以问题的形式导入的，回收了你如何处置，多数同学只知道拿到垃圾收购站去卖，换成钱。为了达到真正的教育目的，这个问题要作适当的引导，让同学知道处置这些垃圾具有更深远的意义。然后接着问：收购站又把这些资料运到哪去呢？同学考虑，提出了不同的意见。有的同学提到废物加工厂加工。这时再创设一个情景：我们到加工厂去看看，然后出示废物加工厂加工流程图片，让同学了解这些资料加工再利用的过程。达到了本课的教学目的。从回收----到利用的过程。接下来进行拓展：这些资料除了送到工厂加工再利用，你还有别的用途吗？出示废旧资料制作的各种玩具。要求同学回去后自制一个玩具。
6总结：
最后进行课堂总结，完成本课的教学任务。
科学课程目标的重点在于培养同学的学习态度和能力发展，所以评价时，我更多的关注同学参与的程度、解决问题的能力，基于这一评价理念，本课我采用了教师评价与同学的自评、互评相结合；小组的评价与组内个人的评价相结合等，在“讨论回收方法、体验回收过程”和“制定回收中心方案”这两个环节中我采取教师评价与同学的自评、互评相结合，在记录表展示和谈体会中我采取了口头褒扬、自评、组评、展示等评价方式。让同学在评价中学会实践和反思、发现自我、欣赏他人。

说课稿数学篇四
我将本课设计为以美术为切入点的综合性艺术课，借助实物游戏、线条游戏、音乐欣赏、美术作品欣赏、即兴绘画表演等手段，将艺术领域里的绘画和音乐等进行自然的融合，让学生在快乐中学习美术，探索不同于单纯美术课和音乐课的新型艺术课教学方法，获得艺术课的教学实践经验。
1、教材内容的地位和作用
通过以上教材分析，为了更好的达到教学目标，突出重点、突破难点，我准备采用下列教学方法。
（一）说 教 法
依据本课的性质及学生的特点，我主要准备采取以下教法：
（1）“启发引导法”，根据学生由感性认识上升到理性认识的认知规律，我以实例为线索，充分动用教具，不断采用欣赏、启发、讨论、归纳相结合的教学方法，在实例的引导下，充分调动学生的积极性和自觉性，让每个学生都能参与到动脑的积极思维中，真正做到面向全体学生，优化课堂教学，提高课堂效率。
（2）“演示法”，根据心理学原理，再造想象是根据词语的描述或图样、图解、符号记录等的示意，在人脑中形成新形象的过程。因此，我针对学生的年龄特点，运用多媒体教具，展示教学相关资料，为学生提供大量的感性材料，让全班学生都能用多种感官感知到演示对象。演示过程中教师的语言与实物、多媒体教具的交替使用，用语言渲染演示，用演示形象地说明讲授的内容，把演示与讲授有机结合，更好地引导学生边看、边听、边思考、边议论，以获得最佳效果。
（3）运用“研究性学习”的方法，让学生在探索中发现、在探索中尝试、在探索中创新，变学生被动学习为主动学习，变“要我学”为“我要学”。
总之本节课的全过程主要是创设各种情境让学生自主学习，主动探究的过程，充分体现学生在学习中的主体地位。
（二）说 学 法
线条是绘画艺术的重要语言与工具，在艺术领域中既有视觉的“线”又有听觉的“线”，理解它们的节奏与情感是比较抽象的，需要全面的知识技能和创造思维，要想让学生在短时间内运用不同节奏的线条来表达各种不同的情感不是一件容易的事。本节课，学生可以在教师创设的情境中借助教师准备的大量实例、音乐等演示和参与体验性学习活动，产生“记忆”与“联想”，在多元的文化环境中形象地认识生活中和自然中的线条以及绘画中的线条，感受听觉的“线”，发展创造思维，陶冶艺术情操，学会人际交往。

《小小鞋店》是北师大版小学数学三年级下第七单元《数据的整理和表示》的数学内容，是学生在学习了一年级上册——“分类”，二年级下册——“调查与记录”的基础上继续学习统计的相关知识。
本单元主要学习收集、整理和分析数据。所用的方法有列表、画图等。为后续学习条形统计图、折线统计图认及平均数的知识奠定基础。
在学生调研中我发现学生在以往学习中积累收集、整理数据的活动经验，他们会用各种不同的方法收集数据，如举手、投票等。在整理数据方面会用填统计表、画正字、写符号等方法进行简单的整理。可见学生已初步积累了数据整理和表示的方法和经验，这是本节课学习的基础。
1、经历收集和整理数据的过程，了解调查收集数据的方法。
2、在初步学会用画图的方法整理数据并呈现数据的结果，能对数据进行简单的分析和过程中，体会数据的价值。
3、在活动交流的过程中不断积累活动经验，形成初步的数据分析观念。
在初步学会用画图的方法整理数据并呈现数据的结果，能在对数据进行简单的分析过程中体会数据的价值。
运用不同方法进行数据收集和整理。
本节课设计了四个教学活动。
活动一、要解决开鞋店“进货”问题，需要知道我们班同学的鞋号，因此分组调查班中同学的鞋号，从班里要开“小小鞋店”这一实际需要引入，激发学生的学习兴趣，通过讨论对“进货”需要调查鞋号、款式、进价等问题的思考，引发对调查数据的研究和讨论。
通过分男、女生两个小组分别调查鞋号，引导学生体会收集数据的方式，并从中体会数据于现实生活，以及收集数据的随机性。学生在调查数据的过程中逐步体会合作的重要性。
活动二：学生独立运用各种方法进行整理，在此基础上学习画点线图整理数据。由于统计表比较乱，所以需要进行整理。让学生在自主尝试中用不同的方法整理原始数据，学习用点线图整理数据的方法，从中体会数据整理的多样性，以及数据整理的准确性，在此过程中使学生体会整理数据的有序性可以使数据的准确性更高，从而培养学生严谨的学习态度。
活动三：通过看整理后的点线图寻找有用的信息，并作出决策。通过从整理后的数据中寻找，发现有用的信息，对数据进行有效的分析，最后为解决问题提出合理的建议。培养学生分析、归纳与概括的能力。
活动四：能过练习巩固，再次体会统计的重要。
本节课设计遵循原则：
本节课的教学设计主要遵循让学生在真实的背景下亲身经历收集数据、整理数据，在分析数据的过程中找到有用信息和做出抉择的全过程，让学生充分体会到数据调查与分析对我们日常生活的影响和重要意义，感受统计的价值。通过经历统计调查活动的全过程，完善方法，提高思想不断积累活动经验，初步发展数据分析观念。

说课稿数学篇八
今天我说课的题目是"解方程(一)"。本节课选自北京师范大学出版社出版的七年级(上),。这一节课是本册书第五章第二节的内容。下面我就从以下四个方面一一教材分析、教材处理、教学方法和教学手段、教学过程的设计向大家介绍一下我对本节课的理解与设计。
分析本节课在教材中的地位和作用,以及在分析数学大纲的基础上确定本节课的教学目标、重点和难点。首先来看一下本节课在教材中的地位和作用。
1、解方程在整个知识系统中的地位和作用是很重要的。初中阶段要培养学生的运算能力、逻辑思维能力和空间想象能力以及让学生根据一些现实模型，把它转化成数学问题，从而培养学生的数学意识，增强学生对数学的理解和解决实际问题的能力。运算能力的培养主要是在初一阶段完成。解方程是代数中的主要内容之一。一元一次方程有许多直接的应用，最主要的，解一元一次方程是学习其它方程和方程组的“基石”。解各种方程和方程组，通过降次、消元等方法，最后都归纳为解一元一次方程。
2、一元一次方程这一章可以归纳为两个方面：第一方面的内容是等式的有关概念，等式的性质以及方程的有关概念；第二方面的内容是一元一次方程的概念，解一元一次方程的步骤，以及列出一元一次方程解应用题。解方程是列一元一次方程解应用题的基础，本章的学习重点在于使学生能根据具体问题中的数量关系列出一元一次方程，掌握解一元一次方程的基本方法，能运用一元一次方程解决实际问题。学生能否正确的解方程和列一元一次方程解应用题关键是这一节的学习。
从以上两点不难看出它的地位和作用都是很重要的。
3、接下来,介绍本节课的教学目标、重点和难点。
教学大纲是我们确定教学目标,重点和难点的依据。根据教学大纲的要求,确定了本节课的教学目标。
1、知识目标是:
（1）熟悉利用等式性质解一元一次方程的基本过程；
(2)通过具体的例子，归纳移项法则；
(3)掌握解一元一次方程的基本方法，能熟练求解一元一次方程（数字系数）能判别解的合理性。
2、能力目标是：
(1)通过学生观察、独立思考等过程、培养学生归纳、概括的能力；
(2)进一步让学生感受到并尝试寻找不同的解决问题的方法。；
3、情感目标是：
(1)激发学生浓厚的学习兴趣，使学生有独立思考、勇于创新的精神，养成按客观规律办事的良好习惯。
(2)培养学生严谨的思维品质。由于合并同类项学生已非常熟悉，系数化成一实际是利用等式的性质，而移项是新事物又是解方程的关键，因此本节课的重点是：移项法则及其应用。由于本阶段的学生往往注意不到项的符号及移向后的符号，很容易出现符号错误。因此我确定本节课的难点是；移项的同时要变号。
本节课是在前面学习了《你今年几岁了》的基础上进行的,学生已经很牢固地掌握了方程、一元一次方程的概念及等式性质并且能利用等式性质熟练的解方程,因此我没有把时间过多地放在复习这些旧知识上,而是通过游戏激发学生的兴趣，这样既巩固了前面所学的知识又培养了学生的创造能力，真是一举三得。进而设疑激发学生的好奇心，为后面的学习做好准备。采用生动形象的事例，在移项法则的得出过程中,我让学生自主观察发现规律并用自己的语言描述规律的内容。然后交流各自所发现的规律及用语言表书的过程，这样通过自主学习、组内交流、合作，达到培养学生自主、互助的精神。由于在移项时，学生常犯一些错误，如移项忘记变号，因此在例题的处理上我采取用两种方法解例1、例2，并将两者加以对照，进而使学生加深对移项法则的理解且自觉改正错误。然后我又选配了一些变式练习,通过书上的基本练习达到训练双基的目的,通过变式练习达到发展智力、提高能力的目的。这些我将在教学过程的设计中具体体现。而且在做练习的过程中让学生互相提问，使课堂在学生的参与下积极有序的进行。
在教学过程中,我注重体现教师的导向作用和学生的主体地位,。本节是新课内容的学习。教学过程中尽力引导学生成为知识的发现者,把教师的点拨和学生解决问题结合起来,为学生创设情境,从而不断激发学生的求知欲望和学习兴趣,使学生轻松愉快地学习不断克服学生学习中的被动情况,使其在教学过程中在掌握知识同时、发展智力、受到教育。
说课稿数学篇九
本课是一篇融文学性、知识性、科学性、哲理性于一体的科普文。文章的开始部分通过日出与日落的对比手法，描绘了日落的壮丽与神秘色彩，接着笔锋一转从多个角度介绍了奇异景象都是由幻觉造成的。从而阐明了大千世界有很多奥妙，我们要学会观察生活，要学会通过现象看本质这样一个道理。
根据新课标的要求、学生身心发展的特点及本课的特点，努力促使学生达到这样的三维目标：
知识与能力目标：整体感知课文内容
过程与方法目标：通过组内合作、探究、讨论、交流，共同探讨疑难问题，培养学生自主、团结合作、勇于创新的精神。
情感态度与价值观目标：培养学生形成注重观察事物，透过现象看本质的意识。
根据学生认知和思维能力的发展及本文的特点预设本文的教学重点、难点。
重点：整体感知全文，了解本文的主要内容
难点：引导同学们体会本文所蕴含的科学道理
多媒体课件
据新《新课标》在《教学中要重视的问题》里指出：“教学过程应突出学生的实践活动，指导学生主动地获取知识，科学地训练，全面提高语文能力。”我根据本课目标和内容，从学生已掌握的知识基础、发展水平出发，应用各种教学手段调动学生的主动性，以激发兴趣法、问题导引法、指导归纳法进行教学。使他们在教师的主导下发表各自的意见，相互交流，相互启发，相互争议，激发他们主动去获取知识。
教法的根本是学法。叶圣陶先生说过：“教是为了达到不需要教。”说的就是这个道理。教学的最终的目的是使学生掌握方法，提高能力。为此，我将通过以下几种方法指导学生进行学习。
1、阅读学习法：在老师的指导下，学生通过阅读教材而获得文中的信息，从而理解课文的内容。
2、质疑释疑法：师生通过共同质疑释疑，探讨和解决问题。
3、问题讨论法：多角度，多思路，寻求多答案，培养发散思维。
为了让学生更好的理解文章，体会本文所蕴含的科学道理，依据课文内容自身的特点，整合知识能力情感等目标，以提高学生语文素养为目的，现设计了听－疑－绘－悟－越－实这六个环节。
每个孩子的心中都有一盏渴求知识的灯，教师应该想方设法去点燃它们。在学习课文之前，先鼓励学生说：“同学们，我们生活在一个充满生机与活力、多姿多彩的世界里，我相信在座的每一位同学都热爱大自然。那么你能不能用你自己的语言描绘一下你所欣赏的落日景观是怎样的呢？”可以通过课件播放轻音乐，欣赏几幅带有落日的图片。经过老师这么一点拨，学生的表现欲就被调动起来了，个个跃跃欲试，表达的欲望也就十分强烈了。
有了那么多的想象之后，学生在好胜心和求知欲下，学习变得相当主动，产生了赶紧学的欲望，这样感知的效果也就不言而喻了。
听，细心倾听，行人更在春山外。
此时利用多媒体课件，一边播放配有声乐（《落日之幻觉》）的范读，一边让学生看课文。学生眼看课文、耳听范读，就会初步的知晓课文大意了
疑，用心质疑，学者须疑方有成。
在听的过程中，请学生把不易懂的字词句划下来。听完以后，请同学相互交流。学生展开想像的翅膀，天马行空，任意驰骋，也可能为一个问题而吵得面红耳赤。
此时老师要做的是巧妙的设疑、正确的引导，比如可以提问：落日的幻觉到底是怎么形成的呢？文章第三段在文中起什么作用等等。古人尝云：学贵有疑。学生在阅读的过程中，会有许多个性化的问题，对课文内容的反应也是多元化的。老师在这个环节中，应当鼓励学生发问，培养质疑精神，促进自主学习。
整篇文章虽然没有太多的科学术语，但是相对于科学性较强的后半部分，有些同学可能理解有些难度，这时候就需要引导大家有重点的去阅读理解，然后把它描绘出来。
绘，移心描绘，落日有情此处着。
在阅读与理解的基础上，老师就引导合作小组的同学根据自己对课文的理解，集思广益，用彩笔描绘出美丽的科学现象，然后每一小组推荐一位同学到黑板上去画，然后给大家解说落日幻觉形成的原因。这样就让每位同学对课文的理解落到了实处，同时也获取了一定的科学知识。
通过几位同学的描述，此时学生一定有很多的话要说，急着倾吐自己内心的感受了。
悟，潜心感悟，谈笑胸中换星斗。
请同学们谈谈，经过刚才一番描绘，你此刻最想说的是什么？
学生你一言我一语的说开了。有的说大自然是神奇的；有的说大千世界有很多的奥妙；还有的说要刻苦学习文化知识，将来去探索更多的奥妙世界。学生在无拘无束的想像，并用自己的语言表达自己的感受，这本是创造，老师又怎能轻易的否定呢？要让学生畅所欲言。在教学过程中，学生的情感一直处于激活的状态，课堂气氛涌动着创造的生命力。
苏霍姆林斯基说过：在人的心灵深处，都有一种根深蒂固的需要，就是希望自己是一个发现者、研究者、探索者，而在学生的精神世界里，这种需要更强烈。
越，齐心超越，腹中诗书气自华。
这时，我就对学生说：“一千个观众就有一千个哈姆雷特，每个同学对这篇文章的见解都很独到，那么哪位同学能告诉大家，学习了这篇文章你懂得了什么？作者难道仅仅是为了揭示落日的幻觉这种现象吗？”
这两个问题一问，同学们愣住了，不知道怎样回答，个个都会到书本上云找答案。这时我就说了：“课文内容我们都已经学习过了，熟悉了。而我们的答案都是写在书本上的吗？”让学生全上课本，让大家静静的思考：作者写这篇文章你感觉还说明了一个什么道理呢？
经过这样一引导，老师带领大家一起走出课本谈生活：比如艺术家美好的幻觉创造出不朽的作品；网络虚拟的幻觉将使人们隐藏在那盛大繁华的城堡里，而远离现实生活，只要一断开连接，城堡瞬间就会崩塌。这时我又会突然间发问：同学们感觉到没有这篇文章的结尾给你什么感觉呢？同学们肯定会发现：这篇文章的结尾好像没有写完。文章写了科学，然后可以再写写生活，把对生活的感悟作为文章的结尾会更好些。学生的话匣子也一下子打开了，把课堂气氛推向了高潮，
如果前面的环节是走进文本，与文本对话，那么此时就是走出文本，进行阅读反思，进一步辩明文本的价值取向、文化品位和艺术特色。
语言课程标准中指出：语言是实践性很强的课程，应着重培养学生语文实践能力，启迪学生把书本知识运用到生活中去。
实，受惊实践，绝知此事要躬行。
请同学们谈，在我们的生活中，还存在什么样的科学现象呢？你是怎样去观察的？对你有什么启示呢？课外时间，让学生去观察大自然，也仿照此课文，写下一篇科学性很强的文章。把这些问题带给学生，与学生们的生活相联系在一起，学生从中体验到语言真有用，学好语言大有作为，同时体会到语言的博大精深。
在这一课的教学设计中，力求集朗读、评价于一体，熔理解、感悟、欣赏于一炉，在整个流程中凸现三个统一：
学生是学习的主人，把说话的权利交给学生，老师只是学习的促进者，引导他们在知识的海洋中不迷失方向，合理处理两者之间的关系是设计的核心。
在确认语言学科的工具性的同时。在课程内容上，充分挖掘教材的人文内涵，在学习方式上构建开放、盥洗的人文气息，在课堂教学上实现师生心灵相通，体现课堂的人文关怀。
本着便捷恰恰高效的原则，讨论与讲授相结合，使学生真正成为学习的主人体验共同学习的乐趣。
总的来说一句话：学生发展举为先，诱疑导思拧成线，个性发言智慧显，活跃气氛课堂现。
