1、知识与技能:了解长方体的特征;认识长方体的长、宽、高;初步认识长方体立体图形。2、过程与方法:经历摸、量,数、分类等操作活动,体会集合和分类思想,变与不变的思想,发展空间观念和空间想象力。3、情感、态度与价值观:学生通过与同学交流发现成果,培养与人合作、自主探索的能力。本课的教学重点是了解长方体和正方体的特征,认识长方体的长、宽、高。教学难点是认识长方体的特征。长方体的特征比较抽象,因此我注重让学生在实践活动中体验、感悟。二、“巧”说教法俗话说:“教学有法,贵在得法。”根据本课的教学内容和学生的思维特点,我将通过情景创设法,运用生活中常见的长方体引入课题;问题启迪法,围绕“哪些物体的形状是长方体或正方体?”和“长方体和正方体各有什么特点?”
二、学情分析本单元是在学生已经学习了整数除法、分数乘法的基础上进行教学的,是小学阶段四则运算中最后一部分的内容。学生学习了整数、小数的四则运算,而分数只学习了加法、减法和乘法,因此对于学习分数除法有一定的认知需求,安排分数除法教学符合学生的认知发展特点。通过整数除法、分数乘法的学习,学生对计算的学习有一定的经验,并具有一定的解决问题的能力,这时候进行分数除法教学,学生有能力将原有的计算方法和经验进行迁移。学生在学习分数乘法时,已经掌握了一些解决分数乘法问题的方法,这时候进行分数除法教学可以促进知识之间的联系,提高学生分析问题和解决问题的能力。教师在教学时,应充分利用资源,激活学生已有的知识经验,引导他们展开类比思维,以促进学习的正向迁移。三、教学目标根据新课标的要求和教材的特点,结合五年级学生的认知能力,本节课我确定如下的教学目标:
1.展示海洋鱼类图片,并导入课题。师:夏季炎热的天气已经开始了,老师带来了一份凉爽礼物想送大家,你们猜猜是什么呢?生:……师:想知道吗?这份礼物就是几张美丽的图片,请看大屏幕:在深蓝色的海底世界里,一群可爱的海洋鱼在悠闲地游来游去,好凉快,好舒服呀。喜欢这个礼物吗? 生:…… 师:喜欢呀,老师太高兴了。同学们再来看一看,在这几张漂亮的图片里,除了让我们感受到大海的凉爽和美丽之外,你还发现什么了吗?
一、说教材:1.说课内容:本节课的内容是北师大版5年级数学下册第8单元的《复式折线统计图》。2.教材分析:这节课的内容是在学生学习了单式折线统计图和复式条形统计图的基础上教学的。这节课的内容包括制作复式折线统计图的必要性、制作方法以及对这种统计图的分析预测。教材在设计中,主要突出了以下两个方面:(1)对比。为了方便比较甲、乙两个城市各月的降水量,把两个单式折线统计图画在同一幅图上,变成复式折线统计图。让学生感受出现复式折线统计图的必要性和其带来的好处。(2)读图。通过对复式折线统计图中两条折线升降的分析,对数据进行合理的预测,这也是课标的要求。3.教材的地位和作用:本课的学习,不但可以用来解决日常生活中的一些实际问题,也是今后学习更多其他统计图的重要基础。
(6)交流。6的乘法口诀一共有几句?口诀中的第一个数与算式中的第二个因数相同,表示什么?口诀中的第二个数与算式的第一个因数相同,表示什么?相邻两句口诀的积相差几?哪几句难记一些?你用什么方法记呢?怎样记住"三六十八"、"四六二十四"两句口诀?教师在学生发言的基础上鼓励学生大胆说、想出不同记口诀的方法。(7)应用"做一做"第1题(学生半独立完成):①用6根小棒摆1个六边形;②摆2个六边形要用多少根小棒?你是怎样想的?(想口诀"二六十二"。)③运用所学的口诀口答摆4个、6个、3个、5个六边形所需要向小棒数。"做一做"第2题(独立完成):①将第2题改为填空题,在圆圈内填写正确的积;②口答得数,并说一说所用口诀。
本课内容安排在学习了2—5的乘法口诀后,考虑到以后每次出现的口诀都比较多,而且较难记,所以学习乘加乘减也是为了帮助学生学习后面的乘法口诀。本课的教学内容有两个特点:一是让学生在实际生活中发现问题,为解决实际问题列出乘加、乘减的算式,并感受解决问题的策略和方法是多样的,通过对各种方法的比较能进一步加强对乘法意义的理解;二是第一册学生已经学过了连加、连减,它的计算顺序是从左到右,依次计算。本册的乘加、乘减都是只教学乘法在前,加、减法在后的题型,计算顺序同样是从左至右;但在教学中,不能让学生这样说,而必须是学生明确要先算乘法,教材的设计就正是如此,没把“先算乘法”作为运算顺序机械的灌输给学生,而是在现实的问题情境中联系解题策略,使学生依据问题的情理确定先算乘法,真正明白算理。根据教材特点,制定如下教学目标知识目标:在实际问题的情境中感受乘加、乘减算式的意义,能用不同的方法解决问题,知道乘加乘减算式的运算顺序。
三、利用乘法口诀进行计算1.复习口诀的含义。任意挑出一句乘法口诀(两个因数不同的),让学生说说它表示什么意思。如"七八五十六",使学生知道它既表示8个7相加是56,又表示?个8相加是56。2.以游戏的方式开展用口诀进行计算的活动。(1)已知两个因数求积的游戏。方法是:请一位学生随意说出一个两位数,另一位学生则将这个两位数的十位数字与个位数字相乘,并算出结果,如果结果又是一个两位数,再将这个两位数的十位数字和个位数字相乘,直至结果是一位数或零。如,一位学生说:"79",另一位学生则口算:7X9=636X3=181X8=8;一位学生说:"58":另一位学生口算:5X8=404X0=0(告诉学生0和一个数相乘得零)一位学生报了3个数以后,互换角色进行。(2)已知积求两个因数的游戏。
(1)Have you ever been to …? Yes, I have. / Yes, I have ever been to …No, I haven’t. / No, I have never been to …(2)When did you go there? I went there last year. (3)I have never been to a water park. Neither have I. I have ever been to an amusement park. So have I. (4)How long have you been studying English? I’ve been studying English since nine o’clock. I’ve been studying English since I came back home. I’ve been studying English for five hours. (5)What’s that? It’s an amusement park in Japan. I’ve never been to an amusement park like it before. It’s fun to learn another language. Let’s go tonight. Isn’t this great?space museum, amusement park, water park, South America, Peru, Holland, European culture, tour guide, flight attendant, musical instrument, more than, be from, get to, take lessons, neither, discover, graduate, change
说明:在帮Li Lei提建议的同时,教育学生如何学好英语。第三课时教学目标1. 语言目标:a) 词汇: Original, in style, haircut, the same as.b) 语言结构:My friend wears the same clothes and has the same haircut as I do.2. 能力目标:大多数学生能够谈论自己喜欢哪种服装,提高查找信息的能力。3. 情感目标:学会如何与朋友相处,要有自己对时尚的看法。教学重点掌握一些重要词汇。教学难点学会谈论问题,并能提出书面建议。◆教学突破首先针对Erin的问题,提出个人的建议,模仿2c部分的对话展开双人交际Pair-work;听老师诵读3a部分的信件,并找出LEFT OUT的问题所在;学生完成3b部分的内容,给Left Out提出书面的建议;学以口头形式提出自己目前存在的某个问题,讲给大家听,让同学们给自己提出一个建议,并作笔录;学生两、三个人分成一组,随意性地进行口语交际,谈论P14的第4部分的某个问题,相互交换意见。
区分宾语从句、定于从句和状语从句宾语从句和状语从句,都叫做主从复合句。宾语从句主要是中考必考的,是初中阶段必掌握的从句,宾语从句主要是掌握三要素,所谓宾语从句,就是宾语在主从复合句当中充当宾语的一个句子,叫做宾语从句。主句的谓语动词是及物动词,后面如果是词或者是短语的话,是简单句,如果是句子的话,肯定是宾语从句。I know that he good at English.就是宾语从句,三要素,一要素是要注意连词,连词一共学了三类连词,一类连词是that口语当中可以省略,就像刚才说的那一句,I hear he is good at English.还有疑问代词、疑问副词,how where when,疑问代词、疑问副词。还有一类连词weather是否的意思,不是状语从句当中的如果,这一定要和如果区分开,这是是否。I don't know if he interested at English。宾语从句要注意if是连词。第二要素是语序,要用陈述举语序。比如说你家有几口人,我们都说How many people are there in you family?但是这是简单句,一旦说成宾语从句,你可以告诉我你家有几口人吗?Could you tell me how many people there are in you family ?
"Hello! Welcome to English class! Introduce yourself. Meet your new classmates." That's what the teacher says. What do you say? "Oh no!" It can be difficult talking to new people. But it can be fun, and you can make friends. How do you do it? Make small talk. Small talk is polite conversation. "Wang Nan is a great pingpang player, isn't she?" "I'd love to meet her, wouldn't you?" "It's been raining a lot, hasn't it?" Tag questions are a form of polite speech. To make small talk successfully, you should know how to make them. You should also know what topics to talk about. Try to learn this unit carefully. The next time you're in English class, you'll find out. Making small talk's easy, isn't it? (“你好!欢迎你!请做一下自我介绍。认识一下你的新同学。”通常在课上老师会这样说。你会说什么呢?“噢,不!”与陌生人谈话太困难了。但是这也很有意思,并且你还能交到朋友。你该怎么做呢?闲聊。闲聊指得是礼貌的对话。“王楠是一个很棒的乒乓球运动员,不是吗?”“我希望自己能认识她,你呢?“今年的雨水很多,不是吗?”反意疑问句是一种礼貌用语。为了使得谈话成功,你应该知道怎样去进行闲聊。你还应该知道与不同的人该谈论什么样的话题。认真的学习这个单元吧,下次在英语课上,你会发现与大家展开谈话是一件很容易的事情,不信我们来试试。)

(一).知识方面: 1.培养学生能运用过去进行时来描述、谈论过去某个时间正在发生的事情或动作的意识和能力,能就过去某个时间正在发生的动作做出正确的描述。 2.培养学生的想象力和角色扮演的合作能力。 3.培养学生讲述过去发生的事情经过的能力。能正确运用一般过去时来讲述故事。 (二).技能方面: 1.本单元的语言目标是Talk about past events and tell a story(谈论过去的时间和讲述一个故事),围绕这一目标,要涉及句型: What were you doing when the UFO arrived? ----I was sitting in the barber’s chair. The barber was cutting my hair. 因此必须学习standing、studying、cleaning、sleeping、cooking、making、eating、cutting、等表示地点的词,以便为上述句型提供语言材料。2.学习过去进行时的有关知识。Was/were+现在分词,是该时态的表达式。 3.在学习过程中,要区分The boy was walking down the street when the UFO landed.和While the boy was walking down the street, the UFO landed.这两种由when和while引导的状语从句的句型结构。注意它们的不同。
教师带领学生复习有关描述宠物的词汇,采用教师提问学生回答的方进行。如:T:What animals do you think would be good pets?What animals do you think would be bad pets?What do you think are good animals for a six-year-old child?然后学生进行 pairwork 练习。Task two: 师生互动,学习探究 1、播放3a部分的录音,引导学生一边听录音,一边跟读。2、通过听录音学生回答以下问题:Why do you think pot-bellied pigs are popular?What are the advantages and disadvantages of keeping such a pet?教师对学生的回答进行及时点评。3.学习范文,学习重点短语,为下步的模仿写作提供语言素材。T :1. )Have you ever kept a pig as a pet?Do you like pigs? St.:No.…Why don’t you like to keep a pig? St: No.They’re too dirty and lazy(Do you know in some foreign countries like Hollyland, Australia,pigs are the most popular pet.there’s a kind of pig.(图)it has an interesting name? it ‘s called a pot-bellied pig.)

Ask students to read the picture and make a list with their partner about how many rules of etiquette can be seen being broken.
二、说教学目标:由于本单元的五个话题都涉及到了不同的条件下所产生的各种结果。所以我确定的本课时的教学目标是:通过谈论图片和身边常见的话题,学会if引导的条件状语从句的用法。即用if条件状语从句作出假设,用will来谈论结果。三、说教学重点:一方面,由于本单元的话题是谈论结果,那么在不同的情境下其结果也会不一样,所以根据不同的情境来推测并谈论各种结果是个重点。另一方面,因为学生没有一个好的语言氛围,所以我侧重于听力和口语的培养,多创设情境能让学生发挥想象,以此激发他们的学习兴趣,。四、说教学难点学生容易记住主句用一般将来时态,从句用一般现在时态,但在判断主句、从句方面容易混淆,因此,我将正确使用主句从句的时态定为本课时的难点。
知识目标:a. 掌握新单词:shout; jump down; climb; scaredb. 掌握并会运用句型:—What were you doing at 8o’clock last night?—I was doing my homework.技能目标:a. 能听懂听力材料的内容,并能做出相应的练习。b. 提高学生听和说的能力。二.教法与学法本节课采取了任务型教学法,通过让学生完成不同的任务来完成不同的教学活动。本节课采用了Brainstorming、Pairwork、Groupwork等活动,实现了让学生说的目标。通过补充故事让学生巩固新学的单词,通过小组的活动让学生参与到问题的讨论中,让学生开口说。三.学情分析通过几个学期的学习,学生已经积累了一定的词汇,并熟练掌握了一些句型。本节课的热身部分是给了学生一个问题:What were you doing at 8 o’clock last night? 通过学生本身的活动来引起他们的兴趣,并对前面的内容进行了复习。四.教学重难点a.掌握本节课所学新单词:shout; jump down; climb; scaredb.掌握和巩固本单元的句型和语法(过去进行时)
七、教学反思在教学过程中全面培养了学生的英语听、说、运用等能力。直观式教学与任务型教学始终融为一体。通过开展活动,充分调动了学生学习英语的积极性、主动性和创造性。What should I do? Section A说课稿我说课的内容是义务教育课程标准实验教科书《新目标英语》八年级下册第二单元Section A,课题是“What should I do ?”本节说课内容分四个步骤:一、说教材 二、说教法 三、说学生 四、说教学过程。一、说教材(一)教材分析教材的地位和作用:第二单元承接八年级上册What’s the matter?中有关情态动词should 的用法,并作进一步的扩展和综合运用;本课是本单元的第一课时,集中呈现了本单元的基本词汇和语言结构,因此,本课教学有着承上启下的重要作用。(二)教学目标1知识目标:学会使用情态动词should、could,学习并使用新单词2能力目标:(1)能够谈论自己的麻烦和问题。(2)能够为他人的问题找到合理的解决办法,提出相应的建议。(3)能够从他人的建议中为自己的问题找到解决办法。
(一) 导入新课(1’)运用多媒体课件,播放有关机器人的视频,引起学生共鸣,激发学生学习兴趣。 边看边展示与课文相关的新单词。让学生想像机器人都是什么样的,机器人能做什么?(这样导入新课,自然创设学习情景,引起学生共鸣,引起学生的兴趣。)(二)快速阅读(skimming)(4’)任务:让学生带着要求快速阅读课文:Get the main idea of the whole passage.这个环节是让学生初读课文,目的是训练快速阅读技巧,学生以较快的速度完成阅读,迅速找到答案。(学法指导:注意:用浏览、跳读和快读的技巧,培养自己快速获有用信息的能力---抓住关键词、主题句和中心大意的能力。Tips: Reading for meaning , not for details(细节).不必逐行阅读(三)深层阅读(5’)任务一:默读文章,回答下列问题,我利用多媒体出示2个问题,(把2个问题打出来)然后让学生带着问题进行有目的阅读。(这样做可以充分利用课本资源,而且化难为易.在全班校对答案之前我让学生先进行同桌相互校对,充分发挥生生互动。)
