教学目标:1、引导学生通过计算、比较、观察、等实践活动,使学生理解倒数的意义,掌握求倒数的方法,并能正确熟练的求出倒数。2、通过自主探究、合作交流的方式培养学生与人合作的能力。3、提高学生学习数学的兴趣,发展学生质疑的习惯。教学重点:知道倒数的意义和会求一个数的倒数教学难点:1、0的倒数的求法。二、说教法基于教材内容比较单调,那么只有在教法上体现新、奇、特,才能让学生想学、要学。在教学过程中,我将始终扮演一个组织者、引导者、合作者的角色,根据小学生从具体的形象思维逐步向抽象的逻辑思维发展的思维特点,联系小学生熟悉的身边实际,使抽象的内容直观化,激发学生的学习兴趣,引导学生去发现问题、讨论问题,放手让他们自主探究和合作交流,帮助他们在自主探究、合作交流中真正理解并掌握本节课的数学知识、技能、思想和方法。
知识与能力目标是:理解反比例的意义,能判断两个量是不是成反比例过程与方法目标是:通过讨论、探究、观察等活动,提高分析问题解决问题人的能力情感态度价值观目标是:培养学生对学习数学的兴趣,感知数学与生活的联系。此外,根据我对教材的解读,我将本节课的教学重点确定为:理解反比例的意义教学难点确定为:判断两个量是不是成反比例二、教法与学法新课标指出:学生是学习的主体,教师是学习的组织者、引导者和合作者,因此首先我采用情境教学法,通过创设情境,激发学生对学习数学的兴趣,;再通过师生互动,探究式教学,为学生创设一个宽松的数学学习环境,相对教师的教法学生采用自主探索,研讨发现的学习方法,让学生成为学习的主人,发挥学生学习数学的积极性和主动性,最后利用练习法:通过适当的练习,巩固所学的知识,解决生活中简单的实际问题
四、说教法、学法我在教学中主要采用的教学方法是先学后教中的“两学两教”。辅之以多媒体教学手段(主要通过微课视频的观看学习)。本课学生的学习方法主要有:自主发现法、合作交流法、自学尝试法等。1.学生在自主探究解答例题,求两种品牌罐头的合格率时,主要采用自学尝试法,根据知识的迁移,学生能够正确求出产品合格率。2.在总结小数、分数化成百分数的方法时,学生主要采用自主发现,合作交流的方法。首先让学生观察例题板书,想一想怎样把小数、分数化成百分数,采用了“兵教兵”的方法,达到了人人参与的目的。当然,由于学生所处的文化环境,家庭背景和自身思维方式的不同,不同的学生所采用的方法也不尽相同,作为教师要尊重学生的选择,允许学生用自己喜欢的方式学习数学。五、说教学过程
④联系生活实际解决身边的问题,让同学初步感受数学与日常生活的密切联系,体验数学的应用,促进学生的发展。接下来,我再具体谈一谈这堂课的教学过程。3、说教学过程第一环节:创设情境,激qing导入。同学们你们看屏幕上的是什么?(出示图片)那么自行车车轮是什么形状的?为什么车轮要设计成圆形?这里面有什么奥妙呢?学了今天的内容大家就会明白的。这节课我们就走进圆的世界去探寻其中的奥妙。板书课题:圆的认识设计意图:通过生活中实际例子引入课题,一方面引起学生的学习兴趣,另一方面为学习新知识做了铺垫,从思想上吸引了学生主动参与学习的活动。这一环节的设计,主要是想体现数学就在我们的身边,从而激发学生学习的兴趣及学习的积极性。
1.必须明确政治生活的作用 (政治生活与经济生活、文化生活是相辅相成的。政治生活直接影响到人民民主的实现程度,影响全体人民利益,也会影响我们的经济生活、文化生活。)2.需要学习政治知识 (5个有助于)3.需要参加政治实践活动。 (参加政治实践的途径;参加政治实践的意义)(通过情景问题,形成学生如何参与政治生活的方法;通过解决问题,培养学生解决问题的能力和发散思维的能力。)环节四 课堂小结 巩固知识本节课我采用线索性的板书,整个知识结构一目了然,为了充分发挥学生在课堂的主体地位,我将课堂小结交由学生完成,请学生根据课堂学习的内容,结合我的板书设计来进行小结,以此来帮助教师在第一时间掌握学生学习信息的反馈,同时培养学生归纳分析能力、概括能力。
Textbook: Senior English for China (Book 4), by Liu Daoyi Time Allotment: 1 period (40 minutes)Date: March 20, 2014Teaching aids: blackboard, Multi-media, Power Point, chalk I. Text Analysis (教材分析)This unit is about body language, and the text selected in the reading part demonstrates the difference and similarity of body language in many parts of the world. Through learning this passage, students are required to raise their awareness of using body language in different parts of the world. As body language is closely related to our daily life, it is easy to arouse students’ interest in learning this text. Reading skills and speaking training are designed around the text.II. Teaching Objectives (教学目标)By the end of the lesson, students will be able to:1. Language Skill Objective(语言技能目标): develop reading ability (skimming and scanning)as well as speaking ability.2. Cultural Knowledge Objective(文化知识目标): know about the cultural differences of using body language.3. Affective Objective(情感目标): increase students’ awareness of using body language correctly in different cultures. III.Teaching Focuses and Difficulties(教学重点和难点)1. Teaching Focuses(教学重点): the difference and similarity of body language in many parts of the world.2. Teaching Difficulties(教学难点): develop students’ reading abilities of skimming and scanning and ask the students to show their opinions with fluent English.
In this step, give students a few minutes to read the passage . While they are reading, I will write some key words of the text on the blackboard. Then ask students to retell the passage according to the key words.By retelling, students can improve their ability of language organization and have an overall understanding of the article.Step 4 Group discussionIn this step, students will be divided into groups of 4 to discussion the following question: What qualities make a great person?After their discussion, invite a few groups to make a report to the class.This group discussion can practice students’ oral English and cultivate their abilities of cooperation and communication.Step 5. HomeworkLet students write a short passage to introduce a great person he or she admires.The homework can consolidate the knowledge the students have learned and cultivate their writing ability. Part 6 Blackboard Design(板书设计)That’s all my teaching procedures. Finally, I’d like to say sth about part 6 blackboard design. On the top is the title. On the left, there will be some new words and expressions. In the middle of the blackboard, I will write some useful sentence structures so that the students can know clearly what they’ve learned and then try to master the knowledge.OK. That’s all for my presentation. Thank you for your attention.
Step 2 Pre-listeningAfter students finish their discussion, I will show a picture of Newton and ask them: Who is him? What is he famous for? Could you find out some words to describe him? Maybe students will answer that he is genius for his finding of theGravitation, making a great contribution to the progress of human being. At that time I will show another two pictures of Einstein and Hawking, letting students guess who they are and write down their idea about the Gravitation. For I have arranged them to search more information about the gravity before this class, Students have beenfamiliar with the topic and will not be afraid about this abstract conception, which is helpful for their listening.Step 3 While-listeningIn this step, students will be required to listen the material for three times. The first and listening is extensive listening and the second and third listening is intensive listening. In the first time, They are required to listen a material including Part 1 and Part 2 and choose the best summary of the listening text. After they choose the right answer, They also need work in group to explain what is wrong with the others. Then I will make a conclusion that we should pay attention to the first paragraph and last paragraph and some keys to get the main idea. By doing this, their capacity of generalization will have a great improvement.Before the second listening, I will ask students to scan the blank on the power point quickly and ask them to note down some key words .Then ask them to listen to the Part 1again and fill the first column of the chart. Maybe some students just show the ideas of these three scientists an still can’t catch their development of gravity. Therefore, I will ask them to listen to Part 2 again and fill in the rest. After finish the listening, I will give them ten minutes to discuss with their partner. I will also guidethem to improve their answers when they discuss with others.
Good afternoon, teachers, It’s my great pleasure to be here sharing my lesson with you.The content of my lesson is Senior English Book 3 Unit 5 Canada —— “The true North”.I’ll be ready to begin this lesson from five parts. Analysis of the teaching material,the teaching methods,the studying methods, the teaching procedure,and Blackboard design.First, let me talk about the teaching material.Part 1 Teaching Material:This unit is about the introduction of Canada. By studying of this unit,we’ll enable the students to learn the geography, population, main cities, and natural beauty, natural resources of Canada. Through the training of the unit, it also requires students to learn some Language skills such as the expressions of position and emotions.So it plays an important part in the English teaching in this book.After studying the teaching material and analyzing the rule of children’s growing of mind,I think the teaching aims are the followings:1.Knowledge objects:(1) make the students learn some new words and phrases(2) make the students understand the content of the lesson.2.Ability objects:(1)To develop the Ss’ abilities of listening, speaking, reading and writing. Especially reading and speaking ability.(2) learn to talk about the characters of Canada in English(3)To train the Ss’ ability of working in pairs.3.Emotion objects:(1)Enable students to understand the characters of Canada..(2)Stimulate Ss to work hard to make China stronger.Part 2 Teaching Methods:I think helping students learn to master new words and phrases and improve the students’ reading and speaking ability is import and the difficult.According to the analysis of the teaching material and the import points and the difficult points,I will use the following teaching methods : question-guiding approach; fast-reading and careful reading; multi-media teaching methods; discussion

Step 4 Reading ----- Theme Parks –---- Fun and More Than Fun1.Predict : Read the title and the pictures on P. 34 and PredictWhat is the meaning of the title “Theme Park – Fun and more than fun”?(The title means that theme parks are fun to visit, but that they can also be educational and can offer useful information.)2.Skimming Fast read and answer:What activities can we take in a theme park?Amusement park: Bumper car Merry-go-round slide bungee jumping Free-fall rides Horror films Pirate ship Ferris wheel roller coaster3.Scanning Read again and you will find various theme parks are mentioned in the passage . Then what are they ?Theme parks: Sports theme park History theme park Culture theme park Marine or Ocean theme Park Future park Science theme park Disneyland4.Careful reading and find the main idea of each paragraph:THEME PARKS---- entertaining/ educationalPara.1 Traditional parks are places to go for relaxation and to have time away from our busy lives.Para.2 Theme parks are different They’re large and full of things to do, see and buy.Para.3 Theme parks are built around a single idea or theme. One example is a sports park.Para.4 Another kind of theme park is historical more and cultural and can be educational.Para.5 Disneylandwas the first theme park. It is based on the fantasy life and characters of Disney’s films.Para.6 Some examples of educational theme parks include sea world parks and science parks.
在接下来的细读环节,我套用了高考对阅读理解的考查方式设置了5个问题,分别为三个推理判断题,一个细节题和一个主旨大意题。学生需要对文章的内容进行分析、归纳、推理、猜测等高级思维活动才能做出正确的回答。【设计意图】这一过程是对学生进行细读的训练,培养学生获取特定信息和挖掘文章深层次信息的能力。第三环节:Intensive-reading (精读) 15′第三个环节精读,既是最重要的环节,也是突破本课重难点的关键。首先,让学生思考剧本中人物看到百万英镑前后的态度发生了怎样的变化。其次,让学生仔细阅读文章,找出可以表现人物态度变化的具体的语言和动作。最后,让学生总结人物的态度发生变化的根本原因是什么,从而引出Money Talks, 供学生思考。【设计意图】通过一系列的活动培养学生学习从人物的语言和动作探究人物的心理,使学生进一步体会戏剧语言的魅力,从而对文章背后所反映的社会问题进行思考,也为下一步的讨论环节做好铺垫。
Good afternoon, everyone. It’s my great pleasure to be here sharing my lesson with you. The content of my lesson is Senior English for China Book5 Unit 3 Life in the Future. I’ll be ready to begin this lesson from six parts: Analysis of the teaching material, Analysis of the students, Teaching aims and important and difficult points, Teaching methods and aids, Teaching procedures, and Blackboard design. First, let me talk about the teaching material.Part 1 Analysis of the Teaching Material:This unit is about what human beings’ life will be like in about one thousand years. By studying of this unit, we’ll Enable the students to know the changes in humans’ life and some new inventions bringing about the change and develop the interest in science. This lesson plays an important part in the English teaching in this unit. This is an important lesson in Book Five. From this lesson, it starts asking the Ss to grasp contents of each passage. Therefore, this lesson is in the important position of the teaching material. If the Ss can learn it well, it will be helpful to make the Ss learn the rest of this unit.Part 2 Analysis of the SsAs Senior2 Ss, they are at different levels of English fluency, some of them have lost interest in English. So during the lesson, I arrange a variety of activities to let all of them join in to attract their interest and let them be confident and taste the joy of success.
分析过焦作市的地理概况和产业优势后,就需要针对由于资源枯竭所带来的问题提出合理化的建议。既然是谈经济转型,就应该将话题的范围明确在这一领域内。通过材料3的相关内容,我们了解到焦作市需要在产业结构调整、培育新的优势产业、增强综合竞争力等三个整改方针上下功夫。因而引导学生针对优势与不足提出建议,以三个整改方针为基准,衡量建议的可行性是锻炼学生解决此类问题的有效途径。在此我将教会学生的是解决问题方法而非案例的内容,正所谓“授之以鱼,不如授之以渔”。接下来针对学生的建议和教材资料分析所罗列的10点整改思路,由学生自由发言提出看法,通过教师的指导和学生的讨论,进而确定经济转型建议的具体方案。最后注意将建议与产业优势相对照,看建议是否都是围绕着产业优势而提出的,这样做会加深学生的印象,通过建议和优势的对应关系,将不难找出此类问题的解题思路。
一、说教材《新年好》 是一节以唱歌为主的音乐综合课,这首歌是一首流行全世界、家喻户晓、深受欢迎的英国儿童歌曲。3/4拍、F大调,曲调优美、流畅,歌词质朴亲切,能将人们带入互相祝贺新年的欢乐情景中,进而表现人们载歌载舞互相祝贺、轻松而愉快的心情。二、说目标1、认知目标:运用亲切、甜美而富有弹性的声音演唱《新年好》,感受中外小朋友过新年的不同音乐情趣。2、技能目标:通过游戏,培养学生感受、听辨已经学过的打击乐器的音色与节奏的能力,并能用动作感受三拍子的强弱规律。3、情感目标:在活动过程中体验过新年、合作学习的愉快。学会热爱今天的幸福生活,热爱世界的音乐文化。丰富学生情感体验,陶冶学生高尚的情操。 三、说重、难点重点是:能以体验的方法、自主探究的方式,学唱歌曲《 新年好》,能主动参与小组创编活动,大胆地进行即兴歌表演。创造性地表现歌曲。 难点是:听辨节奏,用各种方式为三拍子的歌曲伴奏。
三、聆听、表演《小宝宝睡着了》 1、聆听歌曲启发学生说说听到歌曲时感受到了什么?2、复听,跟着歌曲,轻柔地拍节拍。 3、听琴声逐句学唱歌曲。 4、指导学生用连贯、轻柔的声音,唱准、唱好歌曲。 5、重点引导学生说说结尾的处理方式——对比练习,看哪一种方法更恰当 6、引导学生用自己创作的方式为歌曲伴奏、伴舞。 四、小结。 教学反思:一年级课堂上会有一些学生在上课的时候出现喊唱的现象,我在歌曲处理这一环节对歌曲的意境作了这样的描述:静静的夜晚,天上的星星睡了、月亮睡了、地上的鸟儿、虫儿也都进入了梦乡,小宝宝也在悠荡的摇篮里,听着妈妈甜美的歌声,渐渐入睡了。同学们妈妈哄宝宝睡觉唱歌的声音应该是欢快的,还是轻柔的?经过我的描绘和讲解学生理解了在演唱摇篮曲时应该用轻柔的声音,要把每一句都连贯的唱起来,不仅句与句之间要连贯,第一、第二段也要衔接紧凑,轻轻的哼唱出来,体会妈妈哄小宝宝睡觉时是多么的温柔。
3、用木鱼来演奏音乐的不同节奏。(1)师:小动物们都能听着音乐按节奏走路了,下面我想考考你们能不能用这种乐器来演奏不同的节奏呢。(2) 出示木鱼,演示木鱼的演奏方法。师:左手拿木鱼,右手拿木棍,敲的时候要注意不要打在自己的手指上,打在手指上是没有声音的。(3) 玩游戏《听一听》,训练学生的听辨能力和记忆能力。师:我们先来玩一个游戏,老师敲出几个不同的节奏,你们听听哪个是最慢的,哪个是最快的,看谁的耳朵最灵敏。(4) 学生练习演奏木鱼,学会用木鱼敲出不同的节奏,教师个别指导。师:现在就请同学们自己来演奏木鱼,你可以尝试着怎样敲会快一点,怎样会慢一点。(木鱼学生人手一个)[设计思路]在分层教学过程中,由于个别学生的基础比较差,第一和第二段音乐的演奏训练还不能完全掌握,所以花的时间比较长。导致接下的第三和第四段音乐的木鱼节奏训练没有时间完成。我将在第二课时的复习巩固课上再让同学们来练习演奏。
1、视觉图象法:少数民族的风土人情对我们汉族的孩子来说不那么了解。为了使他们更直接地了解到新疆柯尔克孜族人们的生活习惯,我运用电脑软件制作了一些柯尔克孜族的风情画面,给学生视听结合,避免枯燥的说教形式,使本来抽象的 内容变得具体形象化。2、对比欣赏法:在了解这个民族的风土人情时,我运用画面表格形式将新疆几个民族的人物作对比,从而使学生更清楚的了解这个民族的风土人情、歌曲特点。在教学中我还运用了创设情景、兴趣引入法、感性到理性等方法 。音乐家修海林认为“音乐审美必须要求体验到音乐的意境”,在这一课,我充分运用了多媒体教学手段,尽量让学生体验到音乐的意境,从屏幕上看到新疆的风土人情关系,听到新疆民歌不同的风格特点。
1、 教材的地位和作用本课教材所处位置,是小学所学算术数之后数的范围的第一次扩充,是算术数到有理数的衔接与过渡,并且是以后学习数轴、相反数、绝对值以及有理数运算的基础.2、 教学目标①理解有理数产生的必然性、合理性及有理数的分类;②能辨别正、负数,感受规定正、负的相对性;③体验中国古代在数的发展方面的贡献.3、 教学重点和难点教学重点:理解正数和负数的概念和有理数概念.教学难点:对负数概念的理解和有理数的分类.二、 教学分析鉴于初一年级学生的年龄特点,他们对概念的理解能力不强,精神不能长时间集中,但思维比较活跃。我决定采取启发式教学法及情感教学,创设问题情境,引导学生主动思考,用大量的实例和生动的语言激发学生学习兴趣,调节学习情绪。
一、教材分析《认识钟表》是义务教育课程标准实验教科书数学(人教版)一年级上册第七单元的教学内容。本节课要求学生对整时的认识,是学生建立时间观念的初次尝试,为以后“时、分”的教学奠定基础。二、学生分析一年级的学生由于年龄小,刚入学不久,好动、好奇、好玩。大部分学生在学前教育或家庭教育中多多少少都接受过一些关于时间的知识。一般来说,一名6岁的儿童每天起床、吃饭、上课、下课都要按照一定的时间来进行,这样在生活中潜移默化就感知到了时间这一抽象概念的存在。而且几乎每个家庭都有挂钟或手表,钟面、表面对于学生来说并不陌生。三、教学目标 1.初步认识钟面和电子表面,能结合自己的生活经验正确地读、写整时时刻,初步建立时间观念。 2.经历操作、讨论、交流等实践活动,进一步培养学生的动手、动口、动脑的实践应用能力和合作精神,发展数感。
序数是表示集合中元素次序的数,是用自然数表示事物排列的次序,让幼儿回答“第几”的问题。认识序数要以认识基数为基础。本班幼儿已学习了10以内初步数概念的数序,为学习序数做好了准备。学习序数不必像学习基数那样逐个数地形成概念,因此可以分两段集中学习10以内的序数,先学5以内的序数,再学10以内的序数,本节课就将内容定为学习5以内的序数。学习序数要求能从不同方向(从左到右,从右到左,从上到下,从下到上)确认物体的排列次序。由于本节课是第一次接触序数,老师就降低了要求,即从左到右,从下到上来排列物体的次序,这符合幼儿的认知经验。在生活中,幼儿已习惯这两个方向来排列物体的次序。数数是从左到右数的,楼层是从下到上数,避免了逆排序造成的干扰。
