  • 初一数学老师国旗下讲话发言稿

    成功者是需要坚韧的毅力和非凡的勇气的。一个人经历一些挫折并不是坏事情。“自古雄才多磨难,从来纨绔少伟男。”在我们成长的道路上,有坦途,也有坎坷;有鲜花,也有荆棘。在你伸手摘取美丽的鲜花时,荆棘同时会刺伤你的手。如果因为怕痛,就不愿伸手,那么对于这种人来说,再美丽的鲜花也是可望而不可及的。成功永远属于挑战失败的人。我们拥有年轻,年轻没有失败。只要能战胜荆棘,战胜自己,即便是弄行得遍体鳞伤,至少也可以证明我们曾经奋斗过,我们不是挫折的奴隶!

    四、是我本次说课最重要的部分——说教学过程。为达到本节课的教学目标,突出重点,突破难点,我把教学过程设计为:情境导入、讲授新课、巩固练习、归纳总结、布置作业5个阶段。具体过程如下: 第1阶段:情境导入。我将使用多媒体播放“分生日蛋糕”的情境,提出“假设只剩下1/2的生日蛋糕,但需要分给5个人,每个人能分得多少蛋糕?”通过现实生活中的情境,自然而然地引出分数除法的主体。“兴趣是最好的老师”,而对小学生来说,在学习中培养他们的学习兴趣,激发学习的热情尤为重要。教育学和心理学的研究表明,当学习材料与学生已有的知识和生活经验相联系时,学生对学习才会感兴趣。本节课开始由分蛋糕的场景引入,引起了学生的兴趣,紧紧抓住了学生的注意力,同时紧密联系学生的生活实际,让他们感到数学并不神秘,数学就在自己的身边,更激起了他们探索新知的欲望。

  • 人教A版高中数学必修二有限样本空间与随机事件事件的关系和运算教学设计

    新知讲授(一)——随机试验 我们把对随机现象的实现和对它的观察称为随机试验,简称试验,常用字母E表示。我们通常研究以下特点的随机试验:(1)试验可以在相同条件下重复进行;(2)试验的所有可能结果是明确可知的,并且不止一个;(3)每次试验总是恰好出现这些可能结果中的一个,但事先不确定出现哪个结果。新知讲授(二)——样本空间思考一:体育彩票摇奖时,将10个质地和大小完全相同、分别标号0,1,2,...,9的球放入摇奖器中,经过充分搅拌后摇出一个球,观察这个球的号码。这个随机试验共有多少个可能结果?如何表示这些结果?根据球的号码,共有10种可能结果。如果用m表示“摇出的球的号码为m”这一结果,那么所有可能结果可用集合表示{0,1,2,3,4,5,6,7,8,9}.我们把随机试验E的每个可能的基本结果称为样本点,全体样本点的集合称为试验E的样本空间。

  • 人教版高中历史必修3西方人文主义思想的起源说课稿

    苏格拉底把装有毒酒的杯子举到胸口,平静地说:“分手的时候到了,我将死,你们活下来,是谁的选择好,只有天知道。”说毕,一口喝干了毒酒。(2) 苏格拉底临死前对一个叫克力同的人说了这样一番话。克力同,我告诉你,这几天一直有一个神的声音在我心中晓喻我,他说:“苏格拉底,还是听我们的建议吧,我们是你的卫士。不要考虑你的子女、生命或其他东西胜过考虑什么是公正。……事实上你就要离开这里了。当你去死的时候,你是个牺牲品,但不是我们所犯错误的牺牲品,而是你同胞所犯错误的牺牲品。但你若用这种可耻的方法逃避,以错还错,以恶报恶,践踏你自己和我们订立的协议合约,那么你伤害了你最不应该伤害的,包括你自己、你的朋友、你的国家,还有我们。到那时,你活着面对我们的愤怒,你死后我们的兄弟、冥府里的法律也不会热情欢迎你;因为它们知道你试图尽力摧毁我们。别接受克力同的建议,听我们的劝告吧。”

  • 人教版高中政治必修1按劳分配为主体-多种分配方式并存说课稿

    4、课堂讨论:社会主义的根本原则是共同富裕,这也是正确处理分配关系的目标。而十五大报告却进一步明确指出“允许和鼓励一部分人通过诚实劳动和合法经营先富起来,允许和鼓励资本、技术等生产要素参与收益分配”。这矛盾吗?为什么?以小组方式进行讨论,再以代表的形式发表意见,这样既调动了学生的积极性,也使学生对内容有了更深层次的了解。最后老师加以总结,用“蛋糕效应”来阐述“效率优先,兼顾公平”的关系,既形象又贴切,加深学生的理解。本课时内容比较抽象,学生对于概念的理解有较大的难度。因此在教学中我采用多媒体课件教学,联系生活实际,让学生在生活中去体会货币的职责,区分货币的职能,以便达到学以致用的目的。同时适时设置疑问,让学生与我共同思考,真正实现“师生互动,生生互动”,调动学生积极,主动的参与到教学实践活动中。(三)课堂小结,强化认识。(2—3分钟)通过归纳小结,既强调了重点,又巩固了本节知识,帮助学生形成知识网络,便于课后理解记忆。

    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. Guide the Ss to summarize the main idea of each paragraph as well as the main idea of the text.3. Help Ss comprehend the main reasons for space exploration.

    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.
