    1、课件出示教材例1的座位图。教师说明分组方法,从左往右依次为第1列、第2列、第3列直至第6列,从前往后依次为第1行、第2行直至第5行。请学生用自己的语言说说张亮的位置,要求尽可能简洁。当多位学生说完之后,教师组织全体学生评价哪种方法最简洁?当学生一直认同第2列第3行是最简洁的描述方法时,教师板书:第2列第3行。学生主动参与,体会最简表述方法的优越性。2、此时,教师再提出你能用这种方法描述王艳的位置吗?赵强呢?及时反馈,利用最简方法描述其他两位同学的位置。3、让学生完成一个记录游戏:教师快速地报出第几列第几行,让学生记录。学生可能记录不下来。这时教师提出我们要进一步简洁,不用文字,用数字和符号把它的位置记录下来。通过游戏使学生感受到“数对”产生的必要性。学生用自己的方式填写,教师可以选取几位代表在黑板上写,然后提出这些同学记录方法不一样,但有什么相同的地方?引导学生观察发现都有数字2和3,都表示第2列第3行,

    (二)归纳小结。设问:今天学了什么?什么叫轴对称图形?怎样判断轴对称图形?什么叫对称轴?怎样找出轴对称图形的对称轴?(新课后的总结能起到画龙点睛的作用,同时有利于帮助学生理清知识结构,形成完整认识。)现在能把两侧大小不同的蝴蝶图画成一模一样吗?(教师拿着新课引入时的不对称的蝴蝶图)(前后呼应,解答课前疑难,目的是检查学生活用知识的情况。)全课小结:这节课,我通过五个环节的教学设计,既遵循了概念教学的规律,又符合小学生的认知特点,指导学生操作、观察、引导概括,获取新知;同时注重培养学生的形象思维和抽象思维。在教学过程中让学生动口、动手、动眼、动脑为主的学习方法,使学生学有兴趣、学有所获。附板书设计:轴对称图形如果一条图形沿着一条直线对折,两侧的图形能够完全重合,这个图形就是轴对称图形。折痕所在的这条直线叫做对称轴。

    在100以内数的范围里,18比50是少得多,但到了万以内数的范围内,可能只是少一些,所以结合具体情境帮助孩子体会是很重要的教学方法。想想做做第1题是小孩在进行拍皮球比赛,让孩子选合适的答案,在小组中说说是怎么想的,孩子在交流中就能体会到12比46少得多,50比46多一些,85比46多得多;想想做做第2题是发生在校园里的一个场景,让孩子自己选合适的答案,说说怎么想的,孩子就能体会到16比38少的多,36比38少一些,40比38多一些;第3题的场景是在商店里,让孩子先讨论、认识“贵多啦”的含义,在进行选择,在选择、辨析时进一步明白贵多啦就是“用的钱多得多”;最后,和孩子进行一些活动,比比身高(孩子和孩子比、老师和孩子比)、比比身边的一些数量大小,让孩子尝试用语言描述的同时体会数量之间的大小关系,感受到数学就在身边。最后由一个游戏结束本节课,让孩子拿一个数同45比一比,自己想两个数让同桌比一比,练习使用多些、少些多的多、少的多描述两个数量之间的大小关系,增强合作能力。

    3、小结比较观察三种方法,提出问题:为什么同一个问题有三种不同的解决方法?学生交流,教师小结:先解决的问题不同,选择的信息不同,图形拼摆的不同,解决的方法就不同,体现数形结合的思想。相同点是:无论思路如何,都是用连乘的方法解决问题。板书课题:解决问题——两步连乘应用题生活中还有很多这样的清况,想不想再尝试一下。(三)联系生活,优化方法,拓展深化,学校有特异为这些参加比赛的同学们购买了矿泉水,出示画面:共有20箱矿泉水,每箱24瓶,每瓶2元,请问学校共要支付多少钱?学生独立完成观察和思考的角度不同,先后选择的信息不同,所以同一道题有不同的解决方法。看来大家多用连乘的方法解决问题有了进一步的理解。生活中类似这样的问题很多,再来看一看:学校定好了水,付了钱,总得运回来吧.出示搬运车搬水到卡车上的画面:搬运车一次搬4摞,一摞3箱,一箱24瓶,请问搬运车一次能搬多少瓶?

    人教版高中历史必修2第二次工业革命教案2篇

    请回答:根据上述材料,概述第二次工业革命兴起的主要原因。〖参考答案〗①政治上,资本主义制度在世界范围内的确立,为第二次工业革命提供了政权保障。②市场上,世界市场进一步拓展,推动生产进步发展。③科技上,19世纪自然科学的飞速发展与重大突破。④劳动力上,拥有更多、素质更好的自由劳动力。⑤经济上,拥有更加雄厚的资本。探索攻关二:第二次工业革命与垄断组织的出现的关系材料一第二次工业革命产生的新兴工业部门,在厂房、设备、技术要求和产品结构的复杂性等方面,都对生产组织提出了新的要求。这是过去的独家企业无法满足的,而且一般没有足够的资金。……于是,集中资金的合股公司迅速增加起来,起大型企业垄断组织也就应运而生。

    ⑤强调对外关系的灵活性。戈尔巴乔夫指出在对外政策中要采取多种办法选择不同的策略路线达到既定目标。在外交谈判中不要为自己制造死胡同,也不要给对方制造死胡同,要善于迎合伙伴,寻求接触点。在这种思想指导下,苏共采取的对外战略是以军控为中心的缓和战略,具体政策是继续与美国就裁军、消减核武器、限制地区冲突等问题进行谈判,缓解苏美关系;对西欧争取建立“全欧大厦”;对东欧实行纠偏、不干涉政策;对中国改善关系,实现关系正常化;调整与第三世界国家关系,解决阿富汗、柬埔寨等问题。 3、影响:①经济改革措施仓促上马,缺少宏观决策和相应的配套措施;加上戈尔巴乔夫没有放弃苏联的传统做法,继续优先发展重工业,致使改革未达到预期的效果,苏联经济持续下滑②经济体制改革受挫后,把改革的重点转向政治领域,最终导致国内局势的失控和苏联的解体。

    Step 3 Analyzing article structureActivity 31. Teachers raise questions to guide students to analyze the chapter structure of this diary and think about how to describe the festival experience. (1)What should be included in the opening/body/closing paragraph(s)?(2)How did the writer arrange his/her ideas?(3)What kind of interesting details did the writer describe?(4)How did the writer describe his/her feelings/emotions during the event?2. Students read and compare the three sentence patterns in activity 2. Try to rewrite the first paragraph of the diary with these three sentence patterns. After that, students exchange corrections with their partners. Such as:●This was my first time spending three days experiencing the Naadam Festival in China’s Inner Mongolia Autonomous Region and it was an enjoyable and exciting experience. ●I'll never forget my experience at the Naadam Festival because it was my first time to watch the exciting Mongolian games of horse racing, wrestling, and archery so closely. ●I'll always remember my first experience at the Naadam Festival in China’s Inner Mongolia Autonomous Region because it was so amazing to spend three days witnessing a grand Mongolian ceremony. Step 4 Accumulation of statementsActivity 41. Ask the students to read the diary again. Look for sentences that express feelings and emotions, especially those with the -ing form and the past participle. Such as:● …horse racing, wrestling, and archery, which are all so exciting to watch. ● some amazing performances● I was surprised to see…● I was a little worried about. . . ● feeling really tiredOther emotional statements:●I absolutely enjoyed the archery, too, but the horse races were my favourite part. ●I'm finally back home now, feeling really tired, but celebrating Naadam with my friend was totally worth it. ●He invited me back for the winter to stay in a traditional Mongolian tent and cat hot pot. I can’t wait!2. In addition to the use of the -ing form and the past participle, the teacher should guide the students in the appreciation of these statements, ask them to memorize them, and encourage them to use them reasonably in writing practice.

    新人教版高中英语必修3Unit 4 Space Exploration-Listening&Speaking&Talking教学设计二

    The themes of this part are “Talk about how to become an astronaut” and “Talk about life in space”. As Neil Armstrong said “Mystery creates wonder and wonder is the basis of man’s desire to understand. Space is difficult for human to reach, therefore, humans are full of wonders about it. However, if wanting to achieve the dream of reaching the Moon, some of our human should work hard to be an astronaut at first. Part A(Talk about how to become an astronaut) is a radio interview in a radio studio, where the host asked the Chinese astronauts about his story how to become an astronaut. Yang Liwei told his dreamed to be an astronaut since childhood. Then he worked hard to get into college at 22. The next 10 years, he gradually became an experienced pilot. At the same time, to be an astronaut, he had to study hard English, science and astronomy and trained hard to keep in good physical and mental health and to practise using space equipment. Part B (Talk about life in space) is also an interview with the astronaut Brown, who is back on the earth. The host Max asked about his space life, such as his emotion about going back the earth, the eating, shower, brushing, hobbies and his work. Part A and Part B are interviews. So expressing curiosity about the guests’ past life is a communicative skill, which students should be guided to learn.1. Students can get detailed information about how Yang Liwei became an astronaut and Max’s space life.2. Students learn to proper listening strategy to get detailed information---listening for numbers and taking notes.3. Students can learn related sentences or phrases to express their curiosity like “ I wish to know...” “I’d love to know...”4. Students can learn more about the space and astronauts, even be interested in working hard to be an astronaut

    The theme of this unit focuses on “space exploration.” Students will learn about the training and experience needed to become an astronaut. The text is mainly about the development of space exploration. On the one hand, the text helps students to have a good understanding about the great feats humans have achieved, on the other hand, they will further understand the contributions that we Chinese have achieved, and feel confident and proud about our homeland and strengthen their love for our country. The teacher should instruct students to aim high and study harder to make great progress in the space career if possible.1. Read about the development and value of space exploration.2. Explore the mysteries of the universe and the achievements in space exploration.3. Skillfully use the vocabulary of this text to cultivate self-study ability 4. Develop cooperative learning ability through discussion.1. Enable the Ss to talk about the development and value of space exploration.2.

    ⑦在我看来, 探索太空是值得的。As far as I am concerned, it is worthwhile to explore the space.Step 10 Writing---draftRecently, students in our class have had heated a discussion on whether space is worth exploring. Students hold different ideas about it.30% of us think space exploration is not worthwhile. They think space is too far away from us and our daily life and is a waste of money. And the money spent on space exploration can be used to solve the earth’s problems such as starvation and pollution.On the other hand,70% think space is worth exploring because we have benefited a lot from it,such as using satellites for communication and weather forecast. What’s more,with further space research,we may solve the population problem by moving to other planets one day. Also,space research will enable us to find new sources to solve the problem of energy shortages on the earth.As far as I am concerned, it is worthwhile to explore the space. Not only can it promote the development of society but also enrich our life. Step 11 Pair workExchange drafts with a partner.
