“Go for it!” is based on “Task-Based Language Teaching”. It adheres to “The authenticity principle”, “The form-function principle”, “The task dependency principle” and “The principle of learning by doing”. These principles all accord with the demands of curriculum focus.In and of Grade Seven (II), “Go for it!”, students have learned “The Simple Past Tense”. And it appears again in of Grade Eight (I). teaches students more about how to talk about events in the past. In addition, it gives affirmative and negative statements in the past tense, such as the sentence patterns “Did you see …?” “Were there …?” “Did you go …?” As the first part of Unit 8, Section A opens with a picture presenting the last school trip in the aquarium and continues with several step-by-step practice activities, which are all good for students to master “The Simple Past Tense”. Doing well in Section A will help students integrate the new target language with that in Section B. Thus, they can describe the events in the past freely and foster their own ability of reflecting and practicing. II. Teaching ObjectivesTeaching objective is the beginning and aim of teaching activities. According to the overall goal of the English elementary course--- improve students' synthetic ability of language application, which should be based on the development of students’ “Language knowledge”, “Language skills”, “Character building”, “Learning strategies” and “Cross-cultural awareness”. The teaching objectives are described as follows(I). Knowledge objectivesi. Master the simple past tense of regular and irregular verbsii. Recite the new words and expressions about the last school trip in the aquarium, including their pronunciation and intonation

在第1环节基础上,再让同学认识到函数Y=2X-1的图象与方程2X-Y=1的对应关系,从而把两个方程组成方程组,让学生在理解二元一次方程与函数对应的基础上认识到方程组的解与交点坐标的对应关系,从而引出二元一次方程组的图象解法。3、例题训练,知识系统化通过书上的例1,用作图象的方法解方程组,让学生明白解题步骤与格式,从而规范理顺所学的图象法解方程组,例题由师生合作完成,由学生说老师写的方式。4、操作演练、形成技能让学生独立完成书P208随堂练习,给定时间,等多数学生完成后,实物投影其完成情况,并作出分析与评价。5、变式训练,延伸扩展通过让学生做收上P208的试一试,而后给一定时间相互交流,并请代表发言他的所悟,然而老师归纳总结,并让学生通过自已尝试与老师的点拔从“数”与“形”两个方面初步体会某些方程组的无解性,进一步发展学生数形结合的意识和能力。6、检测评价,课题作业
2. 内容内在逻辑本单元亲子之间的交往既承接了上一课的“师生之间”的交往,也为七年级 下册关于中学生提升在集体中的交往水平和能力奠定了坚实的基础,因此本单元 在教材中起承上启下的作用。第一框“家的意味”,通过对“家规” “家训”的探究,引出中国家庭文化中“孝”的精神内涵,引导学生对家庭美德进行深入思考,学会孝亲敬长。第二框“爱在家人间”,通过体验家人间的亲情之爱,进而引导学生感受对 家人割舍不断的情感。第三框“让家更美好”,通过对传统家庭与现代家庭的比较,引导学生认识 现代家庭的特点,树立共创共享家庭美德的意识,共创和谐美德之家。从初识家中“孝”,体验家中“爱”,处理家中“冲突”,到自觉共建家庭 “美德”,学生逐步体味亲情之爱,将“亲情之爱”内化于心、夕卜化于行。(三)学情分析(1) 认知水平与心理特点七年级学生正处于青春期,是生理和心理急剧变化的关键时期,自我意识不 断增强,逆反心理更加强烈,情绪波动较大。
光年是表示较大距离的一个单位, 而纳米(nanometer)则是表示微小距离的单位。1纳米= 米,即1米= 纳米。我们通常使用的尺上的一小格是一毫米(mm),1毫米= 米。可见,1毫米= 纳米,容易算出,1纳米相当于1毫米的一百万分之一。可想而知,1纳米是多么的小。超微粒子的大小一般在1~100 纳米范围内,故又称纳米粒子。纳米粒子的尺寸小,表面积大,具有高度的活性。因此,利用纳米粒子可制备活性极高的催化剂,在火箭固体燃料中掺入铝的纳米微粒,可提高燃烧效率若干倍。利用铁磁纳米材料具有很高矫顽力的特点,可制成磁性信用卡、磁性钥匙,以及高性能录像带等 。利用纳米材料等离子共振频率的可调性可制成隐形飞机的涂料。纳米材料的表面积大,对外界环境(物理的和化学的)十分敏感,在制造传感器方面是有前途的材料,目前已开发出测量温度、热辐射和检测各种特定气体的传感器。在生物和医学中也有重要应用。纳米材料科学是20世纪80年代末诞生并正在崛起的科技新领域,它将成为跨世纪的科技热点之一。
新建成的红星中学,首次招收七年级新生12个班共500人,学校准备修建一个自行车车棚.请问需要修建多大面积的自行车车棚?请你设计一个调查方案解决这个问题.解析:决定自行车车棚面积的因素有两个,即自行车的数量与每辆自行车的占地面积.因此收集数据的重点应围绕这两个因素进行.解:调查方案如下:(1)对全体新生的到校方式进行问卷调查.调查问卷如下:你到校的方式是骑自行车吗?A.经常是 B.不经常是C.很少是 D.从不是(2)根据调查问卷结果分类统计骑自行车的人数;(3)实际测量或估计存放1辆自行车的大约占地面积;(4)根据学校的建设规划、财力等因素确定自行车车棚的面积.方法总结:确定调查方案时必须明确两个问题:(1)需要收集哪些数据?(2)采用什么方式进行调查可以获得这些数据?探究点三:从图表中获取信息小冰就公众对在餐厅吸烟的态度进行了调查,并将调查结果制作成如图所示的统计图,请根据图中的信息回答下列问题:
议一议数轴上的两个点,右边点表示的数与左边点表示的数有怎样的大小关系?数轴上表示的数,▁▁▁边的总比▁▁▁边的大;正数▁▁▁0,负数▁▁▁0,正数▁▁▁负数。练习:比较大小:-3▁5; 0 ▁-4 ;-3 ▁-2.5。3、合作交流(1) 什么是数轴?怎样画数轴。(2) 有理数与数轴上的点之间存在怎样的关系?(3) 什么是相反数?怎样求一个数的相反数?(4) 如何利用数轴比较有理数的大小?5、随堂练习:(1)下列说法正确的是( ) A、 数轴上的点只能表示有理数B、 一个数只能用数轴上的一个点表示C、 在1和3之间只有2D、 在数轴上离原点2个单位长度的点表示的数是2 (2)语句:①-5是相反数?②-5与+3互为相反数③-5是5的相反数④-5和5互为相反数⑤0的相反数是0⑥-0=0。上述说法中正确的是( )
2.法解二元一次方程组,是提升学生求解二元一次方程的基本技能课,在例题的设置上充分体现化归思想.2.在学习二元一次方程组的解法中,关键是领会其本质思想——消元,体会“化未知为已知”的化归思想.因而在教学过程中教师通过对问题的创设,鼓励学生去观察方程的特点,在过手训练中提高学生的解答正确率和表达规范性,提升学生学会数学的信心,激发学习数学的兴趣.3.通过精心设计的问题,引导学生在已有知识的基础上,自己比较、分析得出二元一次方程组的解法,在巩固训练活动中,加深学生对“化未知为已知”的化归思想的理解.特别是如何由代入消元法到加减消元法,过渡自然。让学生深刻的体会到二元一次方程是一元一次方程的拓展,二元一次方程组又要通过“消元”,转化为一元一次方程求解,这样的转化,不仅有助于学生掌握知识、技能和方法,提高学习效率,而且还加深了对数学中通性和通法的认识,体会学习数学和研究数学的规律,提升数学思维能力.
第一环节感受生活中的情境,导入新课通过若干图片,引导学生感受生活中常常需要确定位置.导入新课:怎样确定位置呢?——§3.1确定位置。第二环节分类讨论,探索新知1.温故启新(1)温故:在数轴上,确定一个点的位置需要几个数据呢? 答:一个,例如,若A点表示-2,B点表示3,则由-2和3就可以在数轴上找到A点和B点的位置。总结得出结论:在直线上, 确定一个点的位置一般需要一个数据.(2)启新:在平面内,又如何确定一个点的位置呢?请同学们根据生活中确定位置的实例,请谈谈自己的看法.2.举例探究Ⅰ. 探究1(1)在电影院内如何找到电影票上指定的位置?(2)在电影票上“6排3号”与“3排6号”中的“6”的含义有什么不同?(3)如果将“6排3号”简记作(6,3),那么“3排6号”如何表示?(5,6)表示什么含义? (4) 在只有一层的电影院内,确定一个座位一般需要几个数据?结论:生活中常常用“排数”和“号数”来确定位置. Ⅱ. 学有所用(1) 你能用两个数据表示你现在所坐的位置吗?
2.如何找一条线段的黄金分割点,以及会画黄金矩形.3.能根据定义判断某一点是否为一条线段的黄金分割点.Ⅳ.课后作业习题4.8Ⅴ.活动与探究要配制一种新农药,需要兑水稀释,兑多少才好呢?太浓太稀都不行.什么比例最合适,要通过试验来确定.如果知道稀释的倍数在1000和2000之间,那么,可以把1000和2000看作线段的两个端点,选择AB的黄金分割点C作为第一个试验点,C点的数值可以算是1000+(2000-1000)×0.618= 1618.试验的结果,如果按1618倍,水兑得过多,稀释效果不理想,可以进行第二次试 验.这次的试验点应该选AC的黄金分割点D,D的位置是1000+(1618-1000)×0.618,约等于1382,如果D点还不理想,可以按黄金分割的方法继续试验下去.如果太浓,可以选DC之间的黄金分割 点 ;如果太稀,可以选AD之间的黄金分割点,用这样的方法,可以较快地找到合适的浓度数据.这种方法叫做“黄金分割法”.用这样的方法进行科学试验,可以用最少的试验次数找到最佳的数据,既节省了时间,也节约了原材料.●板书设计
