部编人教版一年级下册《静夜思》（说课稿）
为了使学生能在视、听、说、思等几个环节中经历学习的过程，体验学习语文的乐趣，顺利达成教学目标，我设计的教学过程如下：1.观察交流、激发兴趣、情景导入为了能让学生更好的体会静夜，我设计了这一环节。在上新课前一晚，布置学生去观察夜晚的天空，然后上课时把自己观察到夜空的内容和感受，说给同学听，大家互相交流下。交流后引入新课：静夜思。课题引入后，给学生解释下课题，让学生思考一下，诗人是在什么时候思念，又思念些什么?提问后，把远程教育碟片切到《静夜思》这课，让学生欣赏课文。2.初读古诗，整体感知，认读生字我设计这一环节，是想让学生通过自己朗读课文，去发现这课的生字，并在这环节中，要求学生利用拼音帮助自己读准每个字，尤其是一些后鼻音，让学生成为学习的主人。

高斯（Gauss，1777－1855），德国数学家，近代数学的奠基者之一. 他在天文学、大地测量学、磁学、光学等领域都做出过杰出贡献. 问题1：为什么1＋100＝2＋99＝…＝50＋51呢？这是巧合吗？试从数列角度给出解释.高斯的算法：（1+100）+（2+99）+…+(50+51)= 101×50=5050高斯的算法实际上解决了求等差数列：1，2，3，…，n，"… " 前100项的和问题.等差数列中，下标和相等的两项和相等.设 an＝n，则 a1＝1，a2＝2，a3＝3，…如果数列{an} 是等差数列，p，q，s，t∈N*，且 p＋q＝s＋t，则 ap＋aq＝as＋at 可得：a_1+a_100=a_2+a_99=?=a_50+a_51问题2： 你能用上述方法计算1＋2＋3＋… ＋101吗？问题3： 你能计算1＋2＋3＋… ＋n吗？需要对项数的奇偶进行分类讨论.当n为偶数时， S_n=(1+n)+[(2+(n-1)]+?+[(n/2+(n/2-1)]=(1+n)+(1+n)…+(1+n)=n/2 (1+n) =(n(1+n))/2当n为奇数数时， n－1为偶数
人教版高中数学选择性必修二等差数列的概念（1）教学设计
我们知道数列是一种特殊的函数，在函数的研究中，我们在理解了函数的一般概念，了解了函数变化规律的研究内容（如单调性，奇偶性等）后，通过研究基本初等函数不仅加深了对函数的理解，而且掌握了幂函数，指数函数，对数函数，三角函数等非常有用的函数模型。类似地，在了解了数列的一般概念后，我们要研究一些具有特殊变化规律的数列，建立它们的通项公式和前n项和公式，并应用它们解决实际问题和数学问题，从中感受数学模型的现实意义与应用，下面，我们从一类取值规律比较简单的数列入手。新知探究1.北京天坛圜丘坛，的地面有十板布置，最中间是圆形的天心石，围绕天心石的是9圈扇环形的石板，从内到外各圈的示板数依次为9,18,27,36,45,54,63,72,81 ①2.S，M，L，XL，XXL，XXXL型号的女装上对应的尺码分别是38,40,42,44,46,48 ②3.测量某地垂直地面方向上海拔500米以下的大气温度，得到从距离地面20米起每升高100米处的大气温度（单位℃）依次为25,24,23,22,21 ③

二、典例解析例3.某公司购置了一台价值为220万元的设备，随着设备在使用过程中老化，其价值会逐年减少.经验表明，每经过一年其价值会减少d(d为正常数）万元.已知这台设备的使用年限为10年，超过10年 ，它的价值将低于购进价值的5%，设备将报废.请确定d的范围.分析：该设备使用n年后的价值构成数列{an}，由题意可知，an＝an－1－d (n≥2). 即：an－an－1＝－d.所以{an}为公差为－d的等差数列.10年之内（含10年），该设备的价值不小于（220×5%=）11万元；10年后，该设备的价值需小于11万元．利用{an}的通项公式列不等式求解．解：设使用n年后，这台设备的价值为an万元，则可得数列{an}．由已知条件，得an＝an－1－d（n≥2）．所以数列{an}是一个公差为－d的等差数列.因为a1＝220－d，所以an＝220－d＋(n－1)(－d)＝220－nd. 由题意，得a10≥11，a11＜11. 即：{█("220－10d≥11" @"220－11d＜11" )┤解得19<d≤20.9所以，d的求值范围为19<d≤20.9

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

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.

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.

部编人教版六年级下册《骑鹅旅行记（节选）》说课稿（二）
一、说教材《骑鹅旅行记》是拉格洛芙为儿童写的唯一一部长篇童话。它是根据瑞典教育部的要求，作为学校的地理教育读物而写的，不料后来却成为了世界文学艺术中的珍品。因为拉格洛芙的巨大成就，1914年她被选为瑞典皇家学会会员。在瑞典，现在有一项最重要的儿童文学奖，就是用“尼尔斯”这个名字命名的。《尼尔斯骑鹅旅行记》写了一个不爱学习、喜欢恶作剧的顽皮小男孩尼尔斯历险的故事。一天，尼尔斯因为捉弄了一个小精灵而被小精灵用妖法变成一个拇指大的小人儿，后来，他骑在他家的大白鹅背上跟着一群大雁走南闯北，周游各地，一路上，他增长了许多见识，结识了许多朋友，听了许多故事传说，也经历了无数的危险。在漫长的旅途中，尼尔斯逐渐成长起来，懂得了什么是善恶，学会了同情和爱……

四、说学法学生是学习的主体。皮亚杰认为，在教学过程中，儿童如果不具有自己的意象活动教育就不能成功。1、整体感知，初步了解课文的大概内容。学生先自读课文。自学完以后，概括出文章的主要内容。这样，学生就会从整体上知道这篇课文讲的是什么内容。2、充分自学。人的大脑接受信息，有意注意总比无意注意有效得多。本课内容浅显易懂，可以充分放手让学生自学，经过自学，学生对课文有了一个大概了解，有了一番摸索的功夫，或者是略有解悟，或者是不得要领，或者是困惑不解。一旦进入探讨阶段就会全身心投入。一方面可以从容、有条不紊地发表自己的见解;另一方面略有所悟的急需得以印证和深化，不得要领的急需理清头绪，困惑不解的急需弄个明白，自然都格外注意，毫不懈怠。这样既提高了学习兴趣，又留下了深刻印象，还强化了自主意识。
