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)
二、说教学目标教学目标是一堂课的中心任务,所有教学环节都是为此服务的,课程标准指出:数学教学不仅要考虑数学自身的特点,更应遵循学生学习数学的心理规律??使学生获得对数学理解的同时,在思维能力、情感态度与价值观等方面都得到进步和发展。根据这一要求和本节教学内容,并结合学生的实际情况,本节课我确定如下学习目标:1、知识与技能在熟悉的生活情景中,进一步体会负数的意义;会用负数表示一些日常生活中的问题,知道正负可以相互抵消。2、过程与方法本节课以小组合作学习为主,让学生利用导学案自学,再对学、群学,最后在班里进行展示。整节课都是学生自主学习,积极探索的一个过程。3、情感、态度与价值观经历独学、交流、合作、展示等一系列活动,通过生生、师生互动获得良好的情感体验,同时让学生感受到了数学在生活中的应用。依据这样的教学目标,再结合学生的年龄特点,我运用了浅显易懂的儿童语言制定了导学案上的学习目标。
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。
【设计意图:让学生在操作、探索的基础上,组内交流想法,再在班内交流汇报,让学生的语言得到相互交流、碰撞,从而不断激发学生的思维火花。】师:你能把这些摆法用算式写出来吗?(学生独立写出算式并汇报)依学生汇报板书:1×12=122×6=1212×1=126×2=123×4=124×3=12师:请同学们观察一下,哪两道算式的因数一样?学生观察算式,找出因数一样的算式。师:那么,这6个算式最少能用几种算式表示出来?引导学生说出能用3种方法表示,这三种方法是:1×12=122×6=123×4=12,并指明算式一样时选择其中一种说出来。板书:12=1×12=2×6=3×4师:同学们观察一下,12的因数有哪几个?(学生说出12的因数有:1、12、2、6、3、4。)师:拼长方形与找因数有什么关系呢?(指名学生说一说)师:根据刚才的操作交流,请同学们说一说怎样找一个数的因数呢?(学生思考片刻后汇报,可以组内交流。)引导学生说出:用乘法思路想,看哪两个数相乘得12,然后一对一对找出来。
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。
一、教材:《画一画》这一内容是在学生学习了《变化的量》和《正比例》这两节内容以后安排的,学生已经结合大量的生活情境认识了生活中存在的许多相互依赖的变量,而且体会了这些变量之间的关系,认识了正比例及其意义,能初步判断两个相关联的两是不是成正比例,感受了正比例在生活中的应用,学生对正比例的认识有了一定的基础。教材安排这一内容,一是让学生进一步认识正比例,以及正比例中两个相关联的量之间的关系;二是通过让学生在方格纸上描出成正比例的量所对应的点并能在图中根据一个变量的值估计它所对应的变量的值,从而认识正比例图像的特点。主要意图是引导学生运用已有的知识,用图的形式去直观表示两个成正比例的量的变化关系,鼓励学生发现当两个变量成正比例关系时,所绘成的图像是一条直线,在此基础上,鼓励学生利用图,进行一些估计,解决一些问题,为以后进一步学习正比例函数打下一定的基础。
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.课堂活动中的竞赛制:以记奖评优的形式无声的评价每一个活动,包括个体和小群体。在第一课时评最佳演员和导演奖,第二课时评最佳团体奖,既节约时间又明确有效。使学生能提高语言质量,增强参与意识,提高学习兴趣。2. 教师课堂上语言、表情激励制:在课堂活动中教师要乐于 、善于用激励性语言。从good, super, smart, excellent , great ,wonderful等,用微笑,皱眉,摇头、点头等身体语言对于学生的评价是方便又有效的途径。3.课后作业评价:口头作业在第二天课堂上表演,接受全体同学的评价。笔头作业有教师批阅,以评语的方式出现。优秀作业予以展出或交流。积极地肯定和鼓励学生是我们评价的重要目的之一。4.单元结束后综合性评价:除了笔试以外,也可以根据学生实际开展丰富的活动,如:调查报告、小品表演、专题演讲等。

When it comes to the students’ studying methods, I'd like to introduce my Ss first. The Ss have a good command of basic language points. They’re interested in learning English, and they take an active part in English class, so they will have fun in autonomous, cooperative and inquiry learning. I will just serve as a guide, showing them the way to explore how to make more progress in their English learning.Now it’s time for the most important stage of this lesson. My teaching procedures are arranged as follows:Step1.Leading-in (3 minute)Play a video of a wide variety of wildlife to introduce my topic. Step2. Speaking (12 minutes)We will use our textbook Page25. Let the Ss fast read the short paragraph to warm up. Ask them to talk about the report on some endangered wildlife in China with the dialogue patterns on the screen. Lastly, I will invite some groups to demonstrate their dialogues about saving wildlife in China.Step3.English play (3 minutes)Watch another video in praise of their excellent performance just now. It’s about Jack Chen’s(成龙)and Yang Ziqiong’s wildlife protection.Step4. Listening (twice 13 minutes)This time, I’ll ask the Ss to fill in the blanks of the monologue of the 2 movie stars above. Step5.Discussion (3 minutes)Which would you like to choose to wear, clothes made of cotton, artificial leather or animal skins? Why ?Step6. Summary (3 minutes)1. If there were no wildlife, there wouldn’t exist human beings. If the buying stops, the killing can, too.2. Animals are our friends. To love animals is to love ourselves. Stop hunting, killing and destroying wildlife.3. Let’s live in harmony with all the living things in the world. Step7. Music appreciation (3 minutes)Let the Ss appreciate the song Earth Song by Michael Jackson. Last but not the least, I will show you my blackboard design.
Good morning, distinguished judges:It’s my honor to talk about my teaching ideas with you. Today my topic is Women of Achievement. My presentation consists of six parts: the analysis of teaching material and student, teaching aims, key and difficult points, teaching and studying method, teaching procedures and blackboard design.First, let’s focus on the analysis of teaching material. This lesson is from New Senior English for China Student’s Book 4 Unit 1, the reading part. The main topic of the passage is the introduction of a student of Africanwildlife. After this lesson, the students will learn more information about her studying chimps in Africa, and their reading and speaking abilities can be developed as well.The next part is the analysis of students. My students are in senior high students. They have learnt English for many years, they’ve known many words and sentences, but their speaking and reading abilities are still not very good. So I will practice their speaking and reading abilities through different exercises.According to the New Standard Curriculum and the present situation, I set the teaching aims as follows: firstly, knowledge aims. Students can grasp some new words, such as worthwhile, move off. Moreover, students can understand the content of the passage and get familiar with the topic of studying chimps in wildlife. Secondly, ability aims. Students can use reading strategies such as skimming and scanning in reading process. Thirdly, emotional aims. Students can have the awareness of protecting animals and care about animals.Based on the above analysis, the key point of this lesson is to get the main idea and the detailed information from the passage; the difficult point is to talk about the wildlife protection and use reading strategies.
Language learning needs a context, which can help the learners to understand the language and then can product comprehensible output, so computer has the advantages to make the materials attractive.Part 3 Learning MethodsTask-based, self-dependent and cooperative learningPart 4 Teaching ProcedureStep One Lead-in“Interest is the best teacher.” Therefore, at the very beginning of the class, I should spark the students’ mind to focus on the centre topic “the band”. I’ll show some pictures of food to attract their attention and then bring some questions.Question:What kind of food they like?What should go into a good meal?The answers must relate to the diet. After this, the students will be eager to know something about a balance diet and this is the very time to naturally lead the class into Step 2Step 2 Reading for information: skimming and scanning In this step, I use Task-based Language Teaching method, which can give students a clear and specific purpose while skimming and scanning the context.Task 1 General ideaThe students will be asked to just glance at the title and the pictures of the passage, and then guess what they will read in the text. And they’ll be divided into groups of four to have a discussion.The purpose is to inspire the students to read actively, not passively. In addition, the task is to develop the students’ reading skill by making prediction and to encourage the students to express their thoughts in English and cooperate with each other.Task 2 Main idea of each paragraphCooperative learning can raise the students’ interest and create an atmosphere of achievement. Based on this theory, I divide the whole class into 4 groups to skim the whole text and get the main idea of each paragraph.
In this class, I have 3 teaching aims, that is, knowledge aims, ability aims and emotion aims.1) Knowledge-Teach students new words and expressions, such as temporary, bleed,sprain choke, first aid, fall ill and so on.-Enable students to have a better understanding for some basic knowledge of first aid.2) Ability-Train students’ speaking, reading and writing abilities by different teaching activities, such as skimming, comprehending, team work, role play, retelling and writing.-Develop students’ reading strategy on how to move general idea to specific information.3) Emotion-Promote students’ awareness of giving first aid.- Cultivate students’ creativities.Then let’s come to my teaching methods and activities.III. Teaching methods and activities:To achieve different teaching aims, various kinds of teaching methods and activities will be adopted throughout this period, such as TBL (task-based learning), skimming, team work, brainstorm and others, which can offer students opportunities to fulfill tasks in which they can use language to achieve a specific outcome.IV. Teaching aids:Computer and blackboardV. Teaching important points:1) Make students have a clear mind for the structure of the text.2) Help students understand the theme of the text.VI. Teaching difficulties:1) So many new words may affect students’ understanding.2) How to get students to know about the functions of the skin and thecauses, characteristics and treatments for different degree burns,and the knowledge about giving first aid. VII. Blackboard design:
今天我们来介绍一下必修五第四单元的授课方式。这个单元的题目是Making the news。应该是学生比较感兴趣的话题,学生往往对新闻工作充满好奇,所以我们可以利用这个机会多设计一些师生互动和学生互动,来激发起学习的积极性,提高学习效率。同时我们可以利用这个单元不仅帮助学生掌握语言知识,培养语言能力,同时让其了解新闻工作的重要性,培养起社会智能感。这个单元分为六个课时,它的教学目标是这样的:语言目标是掌握词汇表中的常用单词和短语,掌握倒装句的一些基本用法。 技能目标是能初步掌握约会的基本句型并在真实的场景下正确运用。新闻报道类文章的写作技能。采访的基本规范和沟通技能。情感目标是对新闻报道的客观性和真实性有更好的理解。对新闻记者的职业有更深入的了解,并能体会其工作的重要性。下面我们来介绍一下第一课时的授课方式,第一课的教学目标是这样的第一课时的教学目标语言目标:单词:Occupation, journalist, editor, photographer, curious, personality, enthusiasm
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。
