《一次函数》复习课说课稿
1、教材的地位和作用本章教材是初中数学八年级第十四章的内容，是初中数学的重要内容之一。一方面，这是在学习了函数概念的基础上，对函数知识的进一步深入和拓展；另一方面，又为学习反比例函数、二次函数等知识奠定了基础，是进一步研究数学应用的工具性内容。鉴于这种认识，我认为，本节课不仅有着广泛的实际应用，而且起着承前启后的作用。 2、学情分析针对即将面临中考的学生来说，在具有了一定知识的基础上，培养他们分析问题和解决问题的能力尤为重要，因此本节课除了让学生进一步熟悉本章知识以外，重在培养学生的能力。从认知状况来说，学生在此之前已经学习了函数的定义，对函数的三种表示法已经有了初步的认识，这为顺利完成本节课的教学任务打下了基础，但对于一次函数的性质的理解和应用，仍然是部分学生所存在的困惑，所以在教学过程中要充分利用一些函数的图象，通过直观教学让学生更加深入的理解一次函数的性质。
生活中的数字说课稿
1、数字找朋友——激发幼儿对数学活动的兴趣。 2、找数字——幼儿在食物上找数字，并激励幼儿相互交流，说说自己的发现。 3、生活中的数字——通过讲述、猜想来激励幼儿畅所欲言，充分调动幼儿的积极性，营造轻松愉悦的氛围，拓展幼儿已有的生活经验。 4、幸运号码——通过游戏发现数字的趣味性和丰富性，从而更真切的体会数字的神奇，随便的调换数字的位置就可以排成不同的数字组合。 5、设计电话号码——幼儿运用已有的知识解决问题，为自己编电话号码。让没个幼儿参与其中，从而体验成功感，使他们对数字产生极大的兴趣，激励幼儿在生活中主动观察事物和运用数字，为以后学习奠定基础。
反比例函数说课稿
二)重点、难点及成因分析：重点：反比例函数概念、图象和性质。概念是确定解析式的前提，图象和性质是其灵魂，是数形结合思想方法的具体表现，故是本节的重点。难点：画反比例函数的图象。它的图象有两个分支，且其变化趋势又非直线，学生初次接触，会感到有些困难。(

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

新人教版高中英语必修3Unit 1 Festivals and Celebrations-Reading for writing教学设计二
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.

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. Use this checklist to help your partner revise his/her draft.1.Does the writer explain why he/she changed/wanted to change?2.Does the writer tell how the changes have improved or will improve his/her life?3.Is the text well－organised?4.Does the writer use words and expressions to show similarities and differences?5.Are there any grammar or spelling errors?6.Does the writer use correct punctuation？

第二学期开学安全第一课（国旗下讲话）
第二学期开学安全第一课（国旗下讲话）老师同学们：大家好！今天是新学期的第一天，我们怀着激动的心情，迈着矫健的步伐回到学校，迎接新学期的挑战。今天我将利用一节课的时间围绕“安全”这个话题和大家谈起。因为安全是我们快乐学习与生活的前提，是我们每一个人的心愿。在此，我向全体同学提出以下建议，让我们行动起来，为安全而努力，让安全与我们同行。同学们，生命只有一次、健康不能重来。生命安全就掌握在我们自己手中。安全不仅关系我们个人、更关系到我们身后的家庭、学校、整个社会和整个国家。珍爱生命，增强安全意识，让快乐与幸福伴随我们的童年。今天我与同学们一起交流几个方面的安全问题。一、交通安全1、要遵守交通法规，基本常识有：行人靠右行，不闯红灯，不跨越护栏，横穿公路时要左顾右盼看是否有车辆经过，不脱把骑车，不骑“英雄”车，不跳车，不扒车。2、十二周岁以下的学生不准骑自行车。3、不乘坐黑车，因为黑车是“三无”车，有诸多不安全系数，出了安全问题，费用难以保证，更谈不上赔偿。
