m2,在土壤肥力、施肥、管理等都相同的条件下试种A,B两个品种的小麦.小麦产量如下表:(1)观察下图,哪个品种小麦的产量更高些?(2)以100 m2为单位,如何比较A,B两个小麦品种的单位面积产量?(3)如果只考虑产量这个因素,哪个品种更适合本地种植?思路一教师引导分析:1.通过直观观察,你能得到哪个品种小麦的产量更高些吗?2.要比较哪个品种的产量高,我们通常通过计算什么值定量比较?3.如何求一组数据的平均值?4.你能求出A,B两个小麦品种的单位面积产量吗?5.通过计算,你认为哪个品种更适合本地种植?【师生活动】学生思考回答,独立完成解答过程,小组内交流答案,学生展示结果后,教师点评,并归纳得出结论:由于同一品种在不同试验田上的产量有差异,要比较两个品种哪个产量高,通常情况下是比较它们的平均产量.【课件展示】解:A品种小麦的平均产量:³(95+93+82+90+100)=92(kg),B品种小麦的平均产量:³(94+100+105+85)=96(kg).就试验结果来看,B品种小麦比A品种小麦的平均产量高,B品种更适合本地种植.思路二【师生活动】教师引导学生直观观察哪个品种的小麦的产量高,然后学生独立思考如何计算验证自己的结论是否正确,给学生足够的时间小组内合作交流,完成计算过程,小组代表展示,教师点评并进行归纳.【课件展示】解:A品种小麦的平均产量:³(95+93+82+90+100)=92(kg),B品种小麦的平均产量:³(94+100+105+85)=96(kg).就试验结果来看,B品种小麦比A品种小麦的平均产量高,B品种更适合本地种植.[设计意图]教师引导学生观察统计图,培养学生的读图能力和直观思维,再通过小组合作交流完成计算,提高学生的计算能力,为归纳概括算术平均数的概念做好铺垫,问题情境的引入,有利于学生对平均数的意义和作用进行深入理解.归纳概念教师引导思考:1.如果有n个数x1,x2,…,x n,你如何求它们的平均数?2.每个数与平均数的差的和是多少?(一组数据中,每个数据与平均数的偏差总和为0)【师生活动】学生思考回答,教师点评.师生共同归纳并课件展示算术平均数的概念.【课件展示】一般地,我们把n个数x1,x2,…,x n的和与n的比,叫做这n 个数的算术平均数,简称平均数,记作,读作“x拔”,即(x1+…+x n).因为(x1-)+…+(x n-)=0,所以取平均数可以抵消各数据之间的差异.因此,平均数是一组数据的代表值,它反映了数据的“一般水平”.[设计意图]学生通过回答问题,与教师共同归纳出平均数的概念,并体会平均数反映了一组数据的平均水平,进一步理解平均数的意义,同时培养学生归纳总结能力及数学理解能力.做一做【课件展示】从一批鸭蛋中任意取出20个,分别称得质量如下:8085707585858080758585807585807585708075(1)整理数据,填写统计表.(2)求这20个鸭蛋的平均质量.思路一【师生活动】学生思考后独立完成解答过程,小组内交流答案,教师在巡视过程中帮助有困难的学生,并观察学生计算时的易错点,在点评小组代表的展示时强调易错点,课件展示正确解答过程.【课件展示】解:(1)(2)³(70³2+75³5+80³6+85³7)=79.5(g).即这20个鸭蛋的平均质量是79.5 g.追问:当一组数据中某个数重复出现多次时,我们常怎样计算这组数据的平均数?(先整理数据,列出频数分布表,用简单方法计算平均数)思路二【师生活动】学生独立思考后,教师课件展示小明和小亮的计算方法,小组合作交流,判断他们谁的计算方法正确,并说明理由,教师对学生的展示进行点评,并总结相同的数重复出现多次的时候,计算平均数的方法.【课件展示】小明和小亮分别是这样计算平均数的.小明的计算结果:³(70+75+80+85)=77.5(g).小亮的计算结果:³(70³2+75³5+80³6+85³7)=79.5(g).你认为他们谁的计算方法正确?请和同学交流你的看法.(小亮的计算方法是正确的.由于70,75,80,85出现的频数不同,它们对平均数的影响也不同,所以,频数对平均数起着权衡轻重的作用)归纳:一组数据中某个数重复出现多次时,先整理数据,列出频数分布表,再用简单方法计算平均数.[设计意图]通过小组合作交流,探讨一组数据中某个数重复出现多次时的平均数的计算方法,加深对算术平均数的意义的理解,为下节课学习加权平均数做好铺垫.共同探究二用计算器求平均数【师生活动】学生自主学习课本中内容,然后小组内合作交流,共同归纳用计算器求平均数的方法,并互相出题用计算器求平均数,学生代表展示,教师点评,师生共同归纳用计算器求平均数的一般步骤.【课件展示】求“做一做”中20个数据的平均数的步骤如下(用A型计算器):[设计意图] 学生阅读计算器说明书后,小组合作交流操作方法,归纳操作步骤,培养学生自主学习能力和合作交流能力,同时培养学生归纳总结能力.[知识拓展] 若要了解一组数据的平均水平,可计算这组数据的算术平均数,算术平均数与一组数据的每一个数据都有关系,当一个数据发生变化时,会影响整组数据的平均数,所以算术平均数的缺点是容易受个别特殊值的影响,有时不能代表一组数据的集中趋势.1.统计学是一门与数据打交道的学科,应用十分广泛.本章将要学习的是统计学的初步知识.2.求n 个数据的平均数的公式.3.平均数的简化计算公式.4.用计算器求一组数据的平均数的步骤.1.2015年5月某日我国部分城市的最高气温统计如下表所示:这组数据的平均数是 ( ) A.24 ℃ B.25 ℃ C.26 ℃ D.27 ℃解析:(27+27+24+25+28+28+23+26)÷8=208÷8=26(℃).故选C.2.在一次青年歌手大奖赛上,七位评委为某位歌手打出的分数如下(单位:分):9.5,9.4,9.6,9.9,9.3,9.7,9.0,去掉一个最高分和一个最低分后,所剩数据的平均数是 ( )A.9.2分B.9.3分C.9.4分D.9.5分解析:去掉一个最高分和一个最低分后,所剩数据是9.5,9.4,9.6,9.3,9.7,所以平均数是=9.5(分).故选D.3.若8个数的平均数是11,还有12个数的平均数是12,则这20个数的平均数是 .解析:这些数之和为8³11+12³12=232,故这些数的平均数是=11.6.故填11.6.4.某老师为了了解学生周末利用网络进行学习的时间,在所任教班级随机调查了10名学生,其统计数据如表:求这10名学生周末利用网络进行学习的平均时间. 解:(4³2+3³4+2³2+1³1+0³1)=2.5(小时).即这10名学生周末利用网络进行学习的平均时间是2.5小时.第1课时共同探究一

(2)每名运动员身高与平均身高差的和是0.习题(教材第5页)A组1.解:(1)A厂电池连续使用时间的平均数为(40+48+40+42+43+45)=43(h);B厂电池连续使用时间的平均数为(40+50+45+46+46+52)=46.5(h). (2)B厂生产的电池质量可能更好些.2.解:全年级学生的平均分为≈82.1(分).B组1.解:(1)∵(12.8+12.4+12.2+13.1+12.7)≈12.6(s),(12.2+13.4+12.3+13.5+13.3+12.4+13.0)≈12.9(s).(2)∵12.6<12.9,∴从平均成绩的方面看,甲的实力更强一些.∵甲、乙的最好成绩都是12.2 s,∴从最好成绩方面看,两人的实力相当.2.解:∵(6³5+7³7+8³15+9³25+10³20)≈8.7(环),且8.7>8.4,∴乙的排名领先.关注统计与生活的密切联系统计与现实生活的联系是非常紧密的,这一领域的内容对学生来说应该是充满趣味性和吸引力的,在教学设计时要特别注意将统计的学习与实际问题紧密结合,选择典型的、学生感兴趣的和富有时代气息的现实问题作为例子,在解决这些实际问题的过程中,学习数据处理的方法,理解统计的概念和原理.课标的宏观理念的指导及教材具体素材的活泼灵动,为我们实施教学提供了理论与资源的支持.要通过丰富多彩的教学活动,使学生在解决实际问题的过程中,学会有关的统计知识和方法,体会统计的思想,同时也使学生感受到统计与实际生活的密切联系,以及统计在解决现实问题中的作用.让学生感受“现实的数学、有用的数学”.本节课先从学生熟悉的现实背景抽象出算术平均数的概念,然后在理解概念的基础上,解决有关平均数的实际问题,培养学生应用数学解决实际问题的能力.(1)求下列各组数据的平均数.A.1,2,3,4,5;B.11,12,13,14,15;C.10,20,30,40,50;D.3,5,7,9,11.(2)比较A与B,C,D的计算结果,你能发现什么规律?(3)若一组数据x1,x2,x3,…,x n的平均数为,那么另一组数据3x1-2,3x2-2,3x3-2,…,3x n-2的平均数为.解:(1)=3,=13,=30,=7.(2)A与B比较,B组中各数据比A组中对应各数据多10,所以+10=13.A与C比较,C组中各数据是A组中对应各数据的10倍,所以=10=30.A与D比较,D组中各数据是A组中对应各数据的2倍多1,所以=2+1=7.规律:若一组数据的每一个数都扩大为原来的k倍,则平均数扩大为原来的k 倍;若一组数据的每个数都加或减a,则平均数加或减a.(3)3-2第课时1.理解加权平均数的意义,了解“权”的含义.2.会计算一组数据的加权平均数.3.能说出算术平均数和加权平均数的联系和区别,并能利用它们解决一些现实问题.1.在实际问题情境中理解加权平均数的意义,体会数学与生活之间的密切联系.2.通过利用平均数解决实际问题,发展数学应用能力.3.通过探索算术平均数和加权平均数的联系和区别,发展求同和求异思维.1.通过解决实际问题,体会数学与自然及人类社会的密切联系,了解数学的价值,增进对数学的理解和学好数学的信心.2.通过小组合作活动,培养学生的合作意识,激发学生学习兴趣,体验成功的快乐.【重点】加权平均数的计算及算术平均数与加权平均数的区别和联系.【难点】探索算术平均数和加权平均数的联系和区别.【教师准备】多媒体课件.【学生准备】预习教材P6~8.导入一:复习提问:1.什么叫算术平均数?2.如何求一组数据的平均数?3.当一组数据中同一个数据出现多次时常采用什么简便方法计算?【师生活动】学生思考回答,教师点评.导入二:【课件展示】在一次数学考试中,八年级(1)班和(2)班的考生人数和平均成绩如下表:【问题】1.表格中“86分”所反映的实际意义是什么?2.求这两个班的平均成绩.【师生活动】学生思考后小组合作交流,小组代表发言,教师展示学生可能出现的两种解法,引导学生对比、思考,得出正确的解法,教师导出新课.[设计意图]通过复习算术平均数的概念,做好新旧知识的衔接,以贴近学生实际生活的实例导入新课,渗透“权”的意义,激发学生的学习兴趣,体会数学与生活之间的密切联系,迈上从“算术平均数”到“加权平均数”的一个台阶,让学生顺利完成新知识的构建,为本节课的学习做好铺垫.共同探究加权平均数的概念【课件展示】假期里,小红和小惠结伴去买菜,三次购买的西红柿价格和数量如下表:。

ASingapore started to put labels (标签) on every drink recently.The labels are from A toD.A is the healthiest, and D is the unhealthiest.The more sugar and saturated fat (饱和脂肪) a drink has, the unhealthier the drink is.Grade D drinks aren't allowed to be advertised (打广告) by companies to attract customers.( )1. According to the material, water is in____.A.Grade A B.Grade BC.Grade C D.Grade D( )2. What is the sugar level in the Grade B drink?A.<1%.B.1%-5%.C.5%-10%. D.>10%.( )3. What's the purpose of putting such labels on drinks?A.To stop people buying drinks.B.To guide people to choose healthy drinks.C.To tell people how much sugar is in the drinks.D.To show there are many kinds of drinks.( )4. In which part of a newspaper can we probably read the material?A.Music and Movies.B.Sports and Travel.C.History and Culture.D.Life and Health.BIf you get angry many times in a day, it is time for you to think about how to deal with it. Here are some of my suggestions. When you are angry, try to tell yourself through another voice that you are angry and that it is not a bad thing. It just shows that you have different ideas. Accept that many things are not 100% right or wrong. In our communication with others, the final purpose is not to decide who is right and who is wrong, but to look for something in common.If you still feel strong anger, try taking a deep breath (呼吸) and let anger out of your body along with the breath. Don't say angry words when you are very angry, for you will regret saying them when you cool down.Having a discussion with a third party is helpful. It is hard for the two parties in anger to understand each other, but the idea of an outsider can help both parties to get mutual (相互的) understanding.Anger is just one of the many emotions (情绪) that make us human, and to well manage it adds to our ability to truly understand the world.( )5. What is the final purpose of communication with other people?A.To show different ideas.B.To look for something in common.C.To accept useful suggestions.D.To decide whether one is right or not.( )6. What does the writer advise us to do when we can't cool down?A.Say angry words.B.Try taking a deep breath.C.Control our voices.D.Stop talking with others.( )7. What does the underlined word “party” in Paragraph 3 mean?A.An activity.B.A visitor.C.A person.D.A meeting.( )8.

Don't add too much pressure (压力).Even a few hours a month can make a big difference in someone's life.④Choose an organization with the same interests and common values.⑤Take part in a training meeting for new volunteers, even if it is not asked.⑥Work with an experienced volunteer.He volunteers a lot, and he can help you increase the confidence and completely understand the organization's expectations.⑦Invite friends or family members to serve.It is a good experience to volunteer with them.⑧Finally, it is the most important to enjoy the volunteer experience and to remember that not all volunteer experiences are perfect.If one experience doesn't work, don't give up and you'll surely find the right opportunity.⑨Spend some time on volunteer work and you will see great changes in people's lives.As Mason discovered during his volunteer experience, “…little things can change a person's life.”( )9. Volunteering can help one ____.A.make a decision B.see the world clearlyC.live a better life D.thank other people( )10. What stops people taking the first step toward becoming a volunteer?A.They don't have enough time.B.They are stopped by their family.C.They fear that their abilities are shared.D.They don't expect to become volunteers.( )11.

What was the scanner used to do?A.Record the listeners' brain activity.B.Read the volunteers' ideas.C.Catch the ideas of stories.D.Work out the ideas.( )14. What was GPT1 used to do?A.Receive sounds.B.Test the scanner.C.Produce silent movies.D.Turn recordings of the brain activity into words.( )15. In which way was information put into the volunteers' brains in Test 3?A.Listening.B.Imagining.C.Watching.D.Reading.( )16. Why did the scientists do the tests?A.To show how the tool works.B.To prove that the tool works well.C.To test in which fields the tool can be used.D.To study whose mind can be read.第二节阅读短文,从方框内所给的选项中选出可以填入空白处的最佳选项,其中有一个多余的选项。

同时,要进行分层次授课。
对于基础好的学生要加大知识的容量,拓展知识的层面,使他们更上一层楼;对于基础较差的学生要因势利导,因材施教,使他们在原有的基础上有所提升、有所收获,为将来的学习打好基础。
二、学生情况解析从本次期末的第一次质量展望的成绩来看,九年级( 1 )、( 2 )两班学生的英语学习情况和其他几个班级很相似,学生英语水平宽泛较差,成绩好的不多,部分学生已经对英语失去了信心,还有一部分学生感觉英语越来越难,渐渐力所不及了,不感兴趣了,发言也不是很活跃。
针对这种情况,授课的时候需要注意在备课中增加兴趣性,以此来提升学生对英语学习的兴趣,同时注意在面对绝大多数学生时,侧重打好基础,从最基本的东西抓起,防备拔苗滋生。
三、详详目标和措施:针对以上本质情况,我准备从以下几个方面着手,调整教学目标和授课措施:1、连续针对中考题型的要求,确定如何努力提升学生语言技术:听力方面:能听懂课文大体内容;能抓住简单语段中的看法;回答比较简单的问题。
说即口语表达方面:能使用适合的语调停节奏表达课文马虎;能经过准备就一般话题作短暂表达。
阅读理解方面是个重点,要求能理解阅读资料中不同样的观点和态度;能经过解析句子结构理解难句和长句;加强阅读理解的训练。
写作:能简单写出连结且结构较完满的句子,能在写作文中基本做到文体较规范、语句较畅达;能够较好的达到中招考试对大多数学生的要求。
2、中招考试,既要突出重点,又要顾及全面,坚决坚持分类授课,分层推进的授课思想,使各种学生都能学有所获,都能有所提升。
针对学生英语基础宽泛较差的情况,从基础抓起,抓好英语基础知识。
