为了讲清重点、难点,使学生能达到本节设定的教学目标,我再从教法和学法上谈谈:五、说教法学法我依据“教学有法,教无定法,贵在得法”,同时为了达到既定的教学目标,突出重点,突破难点。本节课我采用的教学方法主要有创设情境法,引导启发法,同时辅以讲练结合,借助现代化的教学手段,以达到良好的教学效果。根据新课标的要求,同时又设计了与教法相适应的学法,我将“学习的主动权还给学生”,通过自主探索,合作交流等方式自主学习,真正让数学教学的课堂变成学生的课堂。六、说教学准备为了更好的达成本节课的课堂教学目标,老师学生需要做如下的教学准备:1、教具:根据教材内容自制的多媒体课件等教具。2、学具:学生以小组为单位准备表格等学具。
1、说教材:本节课是北师大版小学数学四年级下册第94-95页。猜数游戏是在学生已经学习了用字母表示数、方程、等式的性质等知识的基础上进行学习的。本节课主要学会用等式的性质解“ax±b=c”这样的方程,并能用方程解决简单的实际问题。教材通过笑笑和淘气猜数游戏,利用等量关系列出方程,重点是利用等式的性质解方程,能口头检验,形成检验的意识。本节课我通过游戏激发学生的兴趣,使学生体会方程的作用,并产生学习方程解法的愿望,为以后学习解方程、用方程思想解决问题打下重要基础。2、说教学目标:通过猜数游戏的这个情景,让学生会解形如“ax±b=c”的方程,并会简单应用,让学生在此过程中,体验解方程的思路,并掌握方法。在情感、态度、价值观方面,通过游戏,训练学生的数学思维能力,养成善于思考的习惯。3、说重、难点:本节课的重点是会解形如“ax±b=c”的方程,并会简单应用;难点是利用等式的性质解方程
(三)、巩固反馈师:同学们的表现真的令我出乎意料,你们太聪明了,今天我就带大家去数学王国去参观,敢去吗?如果你们能闯关成功就可以免费进入王国的游戏宫,有信心吗?(激励学生,让同学们很快进入巩固练习这个环节中来)第一关:逛同学恩喜爱的食品店(这一关的设计采用抢答的方式进行,更进一步激发学生的学习兴趣,而且巩固了本课重点——计算规律。)第二关:我们来到了你们的妈妈喜欢服装店(这一关先让学生独立尝试,并抽生板演,全班订正,注意强调答语的写法。)第三关:现在我们来到了养鸡场。(这一关仍然采用抢答的方式进行,这道题目主要考察同学们对第二条规律的掌握情况)第四关:进入数学王国继续玩抢答游戏和猜一猜活动(这个环节让学生体会到学习的乐趣)
《比的化简》是北师大版六年级上册第52——53页的教学内容,主要学习化简比的方法。教材联系学生的生活创设问题情境,让学生在解决问题的过程中加深对比的意义的理解,进一步感受比、除法、分数的关系,体会化简比的必要性,学会化简比的方法。在这之前,学生早已学过“商不变的性质”和“分数的基本性质”,最近又认识了比,初步理解了比的意义,以及比与除法、分数的关系,大部分学生能较为熟练地求比值。比较而言,实际上化简比与求比值的方法有相通之处,那么借助知识的迁移能帮助学生顺利理解掌握新知识。二、说教学目标:知识与能力:会运用商不变的性质或分数的基本性质化简比。过程与方法:在实际情境中,让学生体会化简比的必要性,在观察、比较中理解什么是化简比,,并能解决一些简单的实际问题。情感、态度与价值观:促进知识迁移,培养学生的概括能力。体验知识的相通性以及数学与生活的联系。
我说课的内容是北师大版四年级上册第68-70页的《秋游》,我将从教材、教法、学法、教学过程四个方面对本节课进行说课:一.说教材本节课是在学生掌握四舍五入法试商的基础上进行教学的。此前,学生学习的除法都是一次试商成功不需要调商的。本课由秋游搭车的事件引出计算:每个年级各需几辆车?先让学生运用已有知识进行计算,发现不是所有的除法计算一次试商就能成功,需要对所估得的商进行调试,从而掌握除数是两位数的除法笔算。结合教材的特点和学生的实际情况,我确定了如下教学目标:1、知识与技能:让学生在具体情境中,经历四舍五入法试商后进行调商的探索过程,理解试商后调商的原因。并能正确地进行除数是两位数(商是一位数)的笔算。2、过程与方法:让学生在探索计算方法和解决问题的过程中,感受数学与生活的联系,提高学生的估算能力。
《包装》是北师大版四年级下册第三单元第四课时的内容。本课主要让学生探索小数乘小数的竖式计算方法,是在学生掌握小数点位置的移动引起小数大小变化的规律以及积的小数位数与两个乘数的小数位数之间关系的基础上教学的。小数乘法的竖式计算是本单元的重点,是学生正确进行小数乘法计算的关键。课本首先安排了三个问题:第一个问题是结合解决实际问题的过程,会选择适当方法估计运算结果,发展数感,并通过交流进一步理解小数乘法与整数乘法之间相互转化的条件;第二个问题也是结合解决实际问题的过程,掌握小数乘法转化为整数乘法进行运算的一般步骤,从而归纳总结小数乘法的竖式计算方法;第三个问题是经历独立计算和交流小数乘法的过程,体验算法的多样化,发展运算能力。其次安排了6道练习题,目的是为了进一步发展数感,巩固小数乘法的竖式计算方法,体会小数乘法的竖式计算在生活中的应用。
3、变换角度,深入思考第三幅情境图隐含着多样的等量关系,也正是引发学生数学思考的最佳情境。根据学生认识的深入程度,可适当让学生体会到等式的“值等”和“意等”,并放手让学生探究,根据不同的认识找到不同的等量关系,列出等量关系不同的同解方程。在教学中,先引导孩子发现情境中的基本相等关系:2瓶水的水量+一杯水的水量=一壶水的水量,并且列出等式2z+200=2000,在此基础上,再引导孩子发现其他的等量关系。在这一过程中,充分激发孩子探求知识的欲望,调动孩子思考的主动性和灵活性,从而找到多样化的等量关系,并进一步提高孩子解决数学问题的能力。4、建立概念,判断巩固在前面教学的基础上总结、抽象出方程的含义。通过三道例题的简洁数学式子表达,让小组合作寻找他们的共同特点,从而建立方程的概念。“含有未知数”与“等式”是方程概念的两点最重要的内涵。并通过“练一练”让学生直接找出方程。
课程标准中明确指出:“小学数学的教学内容绝大多数可以联系学生的生活实际,找准每一节教材内容与学生生活实际的“切入点”可让学生产生一种熟悉感、亲切感“,以及“数学教学活动中,教师应向学生提供充分从事数学活动的机会,帮助他们在自主探索的过程中真正理解和掌握基本的数学知识与技能。”要将这个理念落实在课堂教学中,就要求教师能根据教学的具体内容,选择恰当的学习方式,并巧妙创设学生主动探索的机会,变“接受学习”为“创造学习”,让学生在观察、操作、讨论、交流、归纳、整理、概括的过程中学习新知,充分以学生为主体,逐步培养学生的创新意识,形成初步的探索和解决问题的能力。根据以上思想,本节课的设计我主要从尊重学生已有的知识经验;在观察与操作中去亲身体验知识的形成过程,掌握约分的方法。
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
The oldest and the most popular park in the worldenjoy the exciting activities thereget close to the life-size cartoon characters like Mickey Mouse and Donald Duck Step 3 Pre-reading1.What do you suppose a theme park is ?2.What do you think you can see in a theme park?(1.It is a kind of amusement park which has a certain theme – that the whole park is based on. 2.buildings, castles, statues, rare animals and birds, and so on.) 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.
4)进行分组练唱、对唱、全体学生合唱。在分组练唱过程中,我将在学生中间进行单独指导,询问他们学习的难点并与学生一起解决,然后适当提问个别学生。通过小组唱、对唱等形式进行演唱评比,提高学生演唱热情。这样,不仅加深了学生对歌曲的熟悉程度,还为学生更好地理解歌曲做了铺垫。5)表演唱,通过表演,不仅展示了学生个性、激发学生的创造力、表现力,而且再次加深了学生对歌曲情感的理解和体验。(三)第三环节——拓展延伸通过对歌曲节拍节奏的改编,让学生感受到得到好朋友原谅后又能快乐的游戏的情绪变化,感受到与好朋友在一起是一件幸福快乐的事。本方案的设计,力求体现以人为本的思想,着眼于学生的主动发展,通过充分的音乐实践,培养学生的能力,提高音乐素养;培养学生的合作意识、探究精神。从目标的提出、到过程的安排、学习方法的确定、乃至学习成果的呈现,都让学生有更大的自主性、更多的实践性。
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。
四、活动总结及反思本次活动,让学生变身“小小侦查员”,调动他们观察发现的积极性,认识到生活中哪些行为是不文明的。运用“新闻直播间”这一新颖的形式,学生在认真聆听讨论之余,知道小小的不文明行为也会造成严重后果。继而通过“情绪体验岛”,引导孩子们在情绪不好的时候,学会自我调整情绪,及时避免不文明行为。最后及时表彰,鼓励其他队员以他们为榜样,使活动主题得以升华。在这一系列充满童趣,层层深入的活动中,同学们表现出了很高的积极性,平时的一言一行都有意识地按文明礼仪的要求做,班风也有了进一步提高。在充分肯定成绩的同时,我们也认识到,不仅要常常开展校园文明礼仪活动,还要开展家庭文明礼仪活动及社会文明礼仪活动,让文明礼仪之花不仅在学校开放,还要开放到家庭、开放到社会,营造出一片人人都讲文明知礼仪的氛围。
(一)教材的地位与作用本节教材包括三方面的内容,(1)全球气候在不断变化之中。(2)全球气候变化的可能影响。(3)气候变化的适应对策三方面说明气候变化及其对人类活动的影响。从标准的要求看,学习的重点不在全球气候变化本身,而是把全球气候变化看作是客观存在的事实,从而探讨全球气候变化对地理环境及人类活动的影响。从资料中可以看出本节教学内容涵盖的时空跨度非常大,思维的链索很长很广,许多问题涉及到学科的前沿及人类所关注的热点,因此,本节课对学生而言既有趣味性,又有挑战性。 (二)教学目标(1)知识与技能目标:1.通过全球气候的长期演变图,学生了解全球气候处在波动变化之中。2.通过资料认识全球气候一直处于变化之中并呈现一定变化周期,了解全球气候变化对地理环境及人类活动的影响,能够提出一些气候变化的适应对策。
在学生热烈的讨论中,理解歌词,感悟新疆。并随机出示课件(课题 新疆是个好地方以及天山、伊犁河、吐鲁番、果子沟的图片)教师及时小结“在新疆这片美丽的土地上,大自然也创作出了它的杰作,用它那神奇的力量,为新疆人民开辟了一处圣地——天山。天山是新疆最大的一条山脉,峰顶白雪皑皑。它是新疆的象征。”在引领学生有感情的朗读歌词时,重点指导学生“乃”字要读轻声才好听。学生按节奏读第二段歌词,教师告诉提醒学生注意一字多音的地方要读正确,如“伊犁河”“果子沟的”等。再次,教师有感情地范唱。教师用语言调动学生的积极性,如“大家读的真有感情,我都忍不住要唱起来了,大家想听吗?如果你觉得老师唱的好听就请拍手为我伴奏吧!”“老师唱的好听吗?相信你们比老师唱的更好听,想不想跟我比一比啊?”
