一、说教材教材中创设了“过河”的情境,通过“河岸上有男生29人,女生25人,每只船限乘9人,需要几只船”这一问题的解决,使学生体会到小括号的作用,从而掌握有小括号的算式的运算顺序。本节教材是贯彻实施素质教育、充分体现新课标精神、培养学生实践能力的很好的教学载体。教学目标:1、结合具体情境,体会四则运算的意义。2、经历与他人交流各自算法的过程。3、能灵活运用不同的方法解决生活中的简单问题,并能对结果的合理性进行判断。4、使学生懂得观察生活,联系实际,体验用数学知识解释生活问题的乐趣,感受数学美,培养热爱数学的情感,激发学生探索客观世界的好奇心和求知欲。教学重点:正确理解并运用小括号,体会小括号在混合运算中的作用。教学难点:探索“小括号”的运用过程。
(3)课堂拓展:是通过提供的三个链接,让学生了解更多的日历。便于学生直接快捷地获取相关信息。锻炼了学生运用网络资源自主学习的能力,使其变为学习的一种新方式。(4)课后作业:充分发挥学生的主动性,创造能力,同时也把所学的数学问题延伸到了课外。通过课后师生的交流,从时间和空间上形成了立体网状的交流信息渠道,促进了学生的发展。最后以时间老人的分别赠言结尾,首尾呼应,对学生进行珍惜时间的教育。五、教学反思本节课我以建构主义理论为指导。依据新课程标准中“重过程,轻结论”的教育理念。尝试在网络环境下,运用设疑激趣、直观演示,实际操作等教学方法,引导学生动手操作、观察辨析、推理验证、自主探究。意在通过信息技术与学科整合,充分发挥网络资源的优势,为学生创设动脑思考、动手尝试、动口表达的时间和空间,把学习的主动权还给学生,在师生互动的动态生成中共同推进学习过程。
第一题:分一分,算一算,你是怎样想的,这题进一步巩固了本堂课的知识。第二题:这道题有利于学生学习知识观念的形成,不仅培养了学生解决问题的能力,而且还有利于学生数学思想和方法的形成。第三题:赛跑这道题解决了学生先前遇到的问题,起到了前后呼应的作用,使学生了解到掌握知识是解决问题的有效途径。第五环节:(课堂小结)这一环节我采用提问的方式引导学生总结,我将提出三个问题:1.这节课我们学习了什么?2.你有什么收获?3.你还有什么问题要问?通过全课总结,使学生对自己的学习过程、方法、成果等进行反思和评价,随着对自己的评价,培养了学生自我激励的意识,也推动学习向更高的层次发展。最后说说板书设计,我的板书设计主要是体现出知识的探究过程,帮助学生回顾知识学习的过程,便于学生记忆。
目标导学四:拓展延伸,仿写句子1.文章描绘百草园,用了“不必说……也不必说……单是……”,把这些词语去掉读一读,跟原文对比,体会作者为什么要这样写。并试着模仿这样的句式写一段话。不必说翠绿的青山,苍劲的松柏,浮动的白云,湛蓝的天空,也不必说夜莺在婉转得歌唱,麻雀在喳喳的嬉戏,美丽的蝴蝶在风中舞动,单是一株不起眼的小草就足以令人心旷神怡,它是那么嫩绿,那么坚强,迎着凛冽的寒风昂然挺立。2.雪地捕鸟这段文字总共不到70个字,连用9个表达动作的词,把雪地捕鸟的系列活动生动而有层次的表现出来了。每句话都写得实实在在,没有可有可无的字句,试写一个游戏,表现系列动作,注意用词准确,不超过100字。他弯着腰,篮球在他的前后不停地拍着,两眼滴溜溜的转动,寻找“突围”的机会。突然他加快了脚步,一会儿左拐,一会儿右拐,冲过了两层防线,来到篮下,一个虎跳,转身投篮,篮球在空中划过一道美丽的弧线后,不偏不倚地落在筐内。
(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。
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。
(一)观图激趣、设疑导入 1.出示课件-情境图师:上节课我们初步学习了里程表的知识,这节课我们接着来研究里程表中的数学问题。板书课题:里程表(二)师:淘气的叔叔是出租车司机。淘气为了记录叔叔每天跑的路程,淘气在叔叔星期一早上出车时,里程表的读数是35千米。淘气记录了叔叔周一至周五每天回家时的里程表读数。(课件展示里程表)。(二)探究新知1.例1(1)师:请同学们认真观看淘气记录的叔叔的周一到周五的里程表,想一想,说一说你知道了哪些数学信息?生:我发现了叔叔周一行了160千米。 师:同学们他说找到数学信息对吗?生:160千米不是星期一的行驶里程,应该是星期一晚上里程表上的读数。 星期二里程表上的读数是350,。生:。。。。师:同学们找的数学信息非常多,非常全面。(2)小组讨论交流:淘气根据题意画了一个图,你看懂了吗?与同伴说一说。
Step 3 (3b)First, tell the students when we talk about our future plans, we often use: I’m+verb+ing When we talk about what we must do, we use have to. Ask the students to fill in the blanks in 3b. The answers are: shopping, go to see, a test, I’m going, my family. Step 4 (3c)Let the students write an e-mail message to a friend. Say why you can’t visit next. Before the exercise, ask the students to give some possible answers and write them on the blackboard. So the students will feel easy to finish the writing exercise. After they finish it, Let them to correct it in groups first. Each group chooses theirs best one to read in front of the whole class. Step 5 ( planning a party )First read the conversation in the box together. Then ask the students to turn to page 88.Write down everything you have to do next week. Write in all the things you have to do . Ask the students to look at the list. Ask them “What day are you free?” This is when you can have your party. Step 6 (Self check 1 )Let the students to fill in the blanks with the words given. Change the forms of the words if possible. Then make their own sentences. The answers are: visit, playing, have to, study, comeStep 7 (Self check 2)Imagine you are Marie. Read the information and look at your schedule. Write replies to the invitation.
1. First, ... then, ... next, ... finally, ...首先,……然后,……接着,……最后,……这是英语中表达做某事的步骤的一种说法。如果步骤较多,还可以说:first-next-after that-later on-finally/at last通常你会听到说英语国家的人在说 first, next, then, finally 和后面的内容时,他们会做一些停顿。这样就能提前告诉听者接下来讲的是一系列的步骤。这一点在朗读和听力中应特别注意。2. how many, how much均为疑问词,同是“多少”,但用法不同。请看:how many修饰可数名词复数,how much修饰不可数名词。但在用法上,同学们常犯如下错误:1) [误] How many are there bananas on the table?[正] How many bananas are there on the table?[析] how many, how much 中的many,much是形容词,常修饰名词作定语,故后面跟名词。2) [误]How much tea are there on the table?[正]How much tea is there on the table?[析] how much修饰不可数名词时,谓语动词用单数。how many与how much的区别可简记为:前how many:问“多少”,复数名词后面跑;how much问“多少”,不可数名词单数好。前者答语用基数词,后者答语用数量关系。
“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

She shouldn’t go to the party tonight.Step7. TaskT: You know, there are lots of problems in our life. If you are a doctor, please tell us how to solve the problem. I will divide you into 9 groups. Please work in groups. And then choose one of you to report your ideas.The following are the problems:I have a toothache.I am hungry. I have a sore throat.I am stressed out. I have a sore back.I am tired. I can’t sleep.I have a cold. I have a headache.Report: If you have a headache, you should go to bed early. You should see the doctor. You should eat some medicine. You shouldn’t wash your face with cold water.You shouldn’t sleep late.You shouldn’t swim.…..T encourages the students to give advice as much as possible.Homework:1. Chose one of the problems, and write down your advice2. Copy the new words这一步是用于热身的,同时也可以让他们复习一部分的表示人体部位的单词,扩充知识.学习语言的过程也是一个不断积累的过程,复习旧知识,增添新知识.通过小游戏,强化学生对Does she/he have…这个句子的运用能力.通过复习,自然的引到下面新知识的学习。充分利用表格,由句子到对话,再到文章,让学生循序渐进. 提高学生的综合语言运用能力,运用以前学过的知识来解决身边的问题.Period 5 (Section B 3a—3c, selfcheck)教学内容与分析:
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。
【设计意图】引导学生梳理文章内容,学习文章层层推理的特色。四、当堂检测《生于忧患,死于安乐》中提出担当大任的人必须经过艰苦的磨炼。请根据查找的相关资料,补充一些例子,并说说你的看法。1.司马迁受宫刑而作《史记》。2.曹雪芹举家食粥而写出了不朽的《红楼梦》。3.贝多芬即使在双耳失聪的情况下,仍然坚持音乐创作。(生交流讨论,举手发言)师小结:美国剧作家帕特里克说:“痛苦使人思索,思索使人明智,智慧使人生命持久。”优越的条件容易消磨人的意志,腐蚀人的健康肌体,使人丧失成功的上进心;而艰苦的环境,坎坷的道路,却能磨炼人的意志,增强人的上进心。学习了本文,希望大家悉心体会,思有所悟,学有所获。【设计意图】增强学生的忧患意识,激励学生要有克服困难的信心和勇气,学会正确对待生活中的困境。
【设计意图】帮助学生理解象征手法,明确本体与象征体的联系,体会作者的情感。通过朗读加深学生对重点句子的理解,让这种精神内化为个人力量。三、练习象征手法的运用请同学们说一说这些形象可以象征什么?课件出示:落叶、荷花、蜡烛、梅花、翠竹、鹰、太阳、孔雀、牛生答:蜡烛燃烧自己照亮别人,可以象征舍己为人的品质,可以象征教师。……师:大家的思路逐渐被打开了,请同学们拿出纸和笔开始写作。注意:本文前半部分是对白杨树的自身形象进行描绘,再通过联想和想象赋予它一定的象征意义,所以同学们不要一开始就写什么物象征什么。结束语:同学们,一篇优秀的散文,就如一幅无形的画,又恰似一首读不尽的诗,茅盾先生的散文达到了如诗如画的艺术境界,白杨树在特定的历史时期被赋予了特定的内涵。让我们再次以茅盾先生写的小诗《题白杨图》作结,向白杨树的精神致敬,向中华儿女身上的正直、质朴、紧密团结、力求上进、坚强不屈的精神和意志致敬!(师生同读教材P81《题白杨图》一诗)
