Don’t fight. =You can’t fight. (板书,教读)教师把这些句子板书在黑板上,并请学生大声整齐地读祈使句和“can’t”句型,并让学生注意两种句型表达形式的不同和转换,“Don’t …=You can’t…”;并对学生说:These are our school rules. (板书,教读) You can’t break the school rules. Don’t break the school rules.(板书,教读)步骤3 :Practicea.

单元整体说明(一)单元教材分析本单元的核心话题是描述动物和表达个人喜好,以及句式why do you like…? Because…。这也是本单元的教学重点。通过本单元的学习,学生应能较流利地运用所学词汇和句型描述动物,表达个人喜好。(二)单元知识结构1.词汇动物名称 tiger, elephant, koala, dolphin, etc.词汇描述性形容词: smart, cute, ugly, clever, shy, etc.国家名: Australia, South Africa2.句型Why do you like koala hears? Because they are cute.Where are pandas from? They're from China.What animals do you like? I like dolphins.(三)单元整体目标1.Master the vocabulary2.Master and use: Why do you like koalas? Because they am cute.Where are pandas from? They're from China.What animals do you like? I like dolphins.(四)单元教学重难点一览(五)单元学情分析学生此前已经学过由why, where, what 引导的特殊疑问句句型,具有了学习本单元知识的认知前提。形形色色的动物能激发学生的好奇心,产生了解它们的欲望,这有利于本单元知识的教学和学生学习兴趣的培养。
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 ?
This activity introduces some new vocabulary and provide oral practice using the target language.Task 1 . Ask four students to stand in front of the class, and the teacher asks them the following questions as a reporter.1.What are you going to do when you grow up?2.What are you going to do next week?3.What are going to do after school?The students will give different answers, then ask a good student to report what they said.I am going to e a doctor.What did she say?----------She said she was going to be a doctor.I am going to have a party on Friday night.What did he say?-------He said he was going to have a party on Friday night.I am going to do my homework.What did she say ?------ She said she was going to do her homework.I am going home after school.What did she say?-----She said she was going home after school.Say In this unit we are going to learn to use words like to report what someone said.Task 2. Read the instructions. Then ask a student to read the four questions. And write the words on the Bb. Explain what soap opera is.Task 3. Ask the students to Look at the pictures, point out the TV screens in the picture. Ask one girl to read what Marcia said.What did Marcia say? She said She said she was having a surprise party for Lana on Friday night. Repeat the other pictures in the same way.Activity3. Listen and number the pictures in activity 1a.
(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。
【设计意图】本环节引导学生走进文本,通过分析千里马的形象,勾连写作背景来了解文章寓意。从而更加深入地理解作者的思想感情。五、总结存储1.教师总结《马说》是经典名篇,文章篇幅短小,仅151字,言简意赅,但引人深思,是“神完气足”之作。韩愈“不平则鸣”的呐喊,是对社会现实的反思,也是一种对于人的生存状态的关怀,是中华优秀传统文化中一笔宝贵的精神财富。2.布置作业在我国封建社会,人才一旦没有得到统治者的赏识,就会被埋没,甚至终生不能施展抱负。我们生活在“海阔凭鱼跃,天高任鸟飞”的时代,只要你有才就一定能有所作为。“千里之行,始于足下。”让我们从现在开始练就本领,以备“千里之行”。课下请同学们以《世有千里马,然后有伯乐》为题,写一篇不少于600字的随笔。
说明:此处进行的是一次尝试应用乘方运算来解决开头的问题,互相呼应,以体现整节课的完整性,把学生开始的兴趣再次引向高潮。趣味探索:一张薄薄的纸对折56次后有多厚?试验一下你能折这么厚吗?说明:这个探索实际上仍是对学生应用能力的一个检查,纸对折56次,用什么运算来计算比较方便,另外计算过程中可使用计算器,进一步加深对乘方意义的理解(五)作业P56页1、2说明:这两个习题是对课本上例题的简单重复和模仿,通过本节课的学习,多数学生应该可以较轻松地完成。总之,在整个教学设计中,我始终以学生为课堂主体,让他们积极参与到教学中来,不断从旧知识中获得新的认识,通过不断进行联系比较,让学生主动自觉地去思考、探索、总结直至发现结果、发现"方法",进而优化了整个教学。
一、教材分析(一)教材的地位和作用:本节课是北师大七年级(上)义务教育课程标准实验教材第2章第6节第一课时的内容。它是学生在已经掌握有理数加法、减法、乘法、除法、乘方以后进行学习的。它是建立在有理数的有关概念和各种运算的意义及法则的基础上进行的综合性运算。它是本章的重点之一,是以上各种运算的继续和发展,对学生运算能力和数学学习能力的培养,有着十分重要的意义,同时也是初中数学运算的重要内容之一,是后续学习的基础。(二)教学目标的确立:参照义务教育阶段《数学课程标准》的要求,确定本节课的教学目标如下:1、知识技能目标:(1)掌握有理数的混合运算法则及运算顺序。(2)熟练的进行有理数的混合运算。2、能力目标:培养学生的观察能力和运算能力。3、情感与态度目标:(1)培养学生在计算前认真审题,确定运算顺序,计算中按步骤审慎进行,并养成验算的良好的学习习惯。
五、两点说明。(一)、板书设计这节课的板书我是这样设计的,在黑板的正上方中间处写明课题,然后把板书分为左右两部分,左边是有理数除法的法则,为了培养学生把文字语言转化成符号语言的能力,板书中只出现两种法则的符号表示,从而加深他们对法则的理解,板书右边是学生的板演,以便于比较他们做题中出现的问题。板书下方是课堂小结,重点写出:有理数的除法可以转化成有理数的乘法,以体现本节课中的重要的数学思想方法。有理数的除法板演练习:有理数除法的法则:a÷b=a×1/b(b≠0) 1a>0,b>0,a/b>0;a0; 2a>0,b0,a/b<0. 3课堂小结:有理数的除法 有理数的乘法转化(二)、时间分配:教学过程中的八个环节所需的时间分别为:1分钟、2分钟、5分钟、8分钟、8分钟、16分钟、2分钟、1分钟。
5、总结学生解题过程中存在的问题,并指导并纠正、分析根本原因。6、通过演示法给学生演示完整、详细和规范的解题过程。7、总结有理数的运算顺序和方法。先让学生自己总结运算顺序,培养学生自己思考的能力,然后教师进行纠正。等这个过程结束之后,再给出完整的运算顺序和方法。8、出示练习题,巩固所学知识,教师及时指正。9、最后布置课后作业题。四、教学评价本节课我注重体现“以教师为主导、学生为主体、以学生发展为本的教学思想”。1、通过具体的题目引入,让学生先以自己的知识体系解决问题,在这过程中发现问题、归纳总结原因,并予以解决。一方面复习前面所学的基本运算,另一方面完善学生的知识体系。2、培养学生自主学习与探究的能力、分析与解决问题的能力。
“数的运算”是“数与代数”学习领域的重要内容,减法是其中的一种基本运算.本课的学习远接小学阶段关于整数、分数(包括小数)的减法运算,近承第四节有理数的加法运算.通过对有理数的减法运算的学习,学生将对减法运算有进一步的认识和理解,为后继诸如实数、复数的减法运算的学习奠定了坚实的基础.鉴于以上对教学内容在教材体系中的位置及地位的认识和理解,确定本节课的教学目标如下:1、知识目标:经历探索有理数的减法法则的过程,理解有理数的减法法则,并能熟练运用法则进行有理数的减法运算.2、能力目标:经历由特例归纳出一般规律的过程,培养学生的抽象概括能力及表达能力;通过减法到加法的转化,让学生初步体会转化、化归的数学思想.3、情感目标:
四、教学过程分析为有序、有效地进行教学,本节课我主要安排了以下教学环节:(一)复习导入主要复习一下三种统计图,为接下来介绍三种统计图的特点及根据实际问题选取适当的统计图做好知识准备。(二)问题探究选取课本上“小华对1992~2002年同学家中有无电视机及近一年来同学在家看电视的情况”的3个调查项目,进而设计3个探究问题从而加深学生对每一种统计图的进一步认识,至此用自己的语言总结出每一种统计图的特点。(三)实践练兵这一环节通过2个实际问题的设计,通过学生对问题的分析、讨论,使学生认识到适当选取统计图有助于帮助人们去更快速、更准确地获取信息。(四)课堂小结总结这一节课所学的重点知识,这部分主要是让学生自己去总结,看看这节课自己有哪些收获。(五)作业布置进一步巩固本节课所学的知识,达到教学效果。以上就是我对这节课的见解,不足之处还望批评和指正。
(六)当堂达标(练习二、三 10分钟)练习二让学生口答,通过练习,巩固学生对直线、射线、线段表示方法的掌握。练习三让学生去黑板板演,教师检验对错并重点强调几何语言的表述。文字语言和图形语言之间的转化是难点,着重练习文字语言向图形语言的转化,提高几何语言的理解与运用能力。当堂达标是检查学习效果、巩固知识、提高能力的重要手段。通过练习,学生会体验到收获和成功,发现存在的不足,教师也及时获得信息反馈,以便课下查漏补缺。 (七)小结(3分钟)教师提问“这节课我们学了哪些知识?”请学生回答,教师做适当补充。课堂小结对一节课起着“画龙点晴”的作用,它能体现一节课所讲的知识和数学思想。因此,在小结时,教师引导学生概括本节内容的重点。
一是先用计算器算出下面各题的积,再找一找有什么规律。目的是活跃气氛,激发学生探索数学规律的兴趣,为下面的数学探险作铺垫。二是数学探险。在这个步骤中,我先出示8个1乘8个1,学生用计算器计算的答案肯定不一样,因为学生带来的计算器所能显示的数位不一样,而且这些计算器所能显示的数位都不够用,也就是这道题目计算器不能解决。这时我提问:“你觉得问题出在哪儿?是我们错了,还是计算器错了?你能想办法解决吗?请四人小组讨论一下解决方案。”这样安排的目的是引发矛盾冲突,激发他们解决问题的需要和欲望。在学生找不到更好的解决方法时,引导学生向书本请教,完成课本第101页想想做做的第四题。让学生利用计算器算出前5题的得数,引导学生通过观察、比较、归纳、类比发现这些算式的规律,填写第6个算式,发展学生的合情推理能力,同时也让学生领略了数学的神奇。
