人教A版高中数学必修一对数的概念教学设计（2）
对数与指数是相通的，本节在已经学习指数的基础上通过实例总结归纳对数的概念，通过对数的性质和恒等式解决一些与对数有关的问题.课程目标1、理解对数的概念以及对数的基本性质；2、掌握对数式与指数式的相互转化；数学学科素养1.数学抽象：对数的概念；2.逻辑推理：推导对数性质；3.数学运算：用对数的基本性质与对数恒等式求值；4.数学建模：通过与指数式的比较，引出对数定义与性质.重点：对数式与指数式的互化以及对数性质；难点：推导对数性质．教学方法：以学生为主体，采用诱思探究式教学，精讲多练。教学工具：多媒体。一、 情景导入已知中国的人口数y和年头x满足关系 中，若知年头数则能算出相应的人口总数。反之，如果问“哪一年的人口数可达到18亿，20亿，30亿......”，该如何解决？要求：让学生自由发言，教师不做判断。而是引导学生进一步观察.研探.
人教A版高中数学必修一集合的概念教学设计（2）
例7 用描述法表示抛物线y＝x2＋1上的点构成的集合．【答案】见解析 【解析】 抛物线y＝x2＋1上的点构成的集合可表示为：{(x，y)|y＝x2＋1}．变式1．[变条件，变设问]本题中点的集合若改为“{x|y＝x2＋1}”，则集合中的元素是什么？【答案】见解析 【解析】集合{x|y＝x2＋1}的代表元素是x，且x∈R，所以{x|y＝x2＋1}中的元素是全体实数．变式2．[变条件，变设问]本题中点的集合若改为“{y|y＝x2＋1}”，则集合中的元素是什么？【答案】见解析 【解析】集合{ y| y＝x2＋1}的代表元素是y，满足条件y＝x2＋1的y的取值范围是y≥1，所以{ y| y＝x2＋1}＝{ y| y≥1}，所以集合中的元素是大于等于1的全体实数．解题技巧（认识集合含义的2个步骤）一看代表元素，是数集还是点集，二看元素满足什么条件即有什么公共特性。
形式主义官僚主义突出问题的调研报告
存在问题 文山会海问题突出，干部群众反映较为强烈。县乡基层“以会议落实会议、以文件落实文件”问题尚未得到有效解决。一些单位和部门正式发文虽然有所减少，但是利用电话传真、微信短信、电子邮箱等渠道变相发文数量依然较多。有的地方存在层层发文、照搬照抄上级文件、缺乏针对性的问题。有的会议表面规格高、规模大，动辄要求一把手参加，或者为了体现规模让与会议内容关系不大的部门参加。 督查检查考核项目多，有些检查考核内容重复。调研组对该市各类考核项目进行梳理，发现一些省、市两级考核项目内容相似，但所需准备材料规格不尽相同。如，文明城市创建和卫生城市创建两项考核，内容交叉重复，需要准备两套资料，浪费了大量人力物力。
建设工程安全生产存在问题的调研报告
（一）建设单位的责任。建设单位在工程建设体系过程中处在优势地位，其安全生产重视程度直接影响监理单位和施工单位的安全责任意识及其对工程项目的安全管理力度。目前，因建设单位导致重大生产安全事故发生的比例始终较高。究其原因：一是不办理安全措备案擅自开工建设，规避监管。二是将工程发包给不具备安全生产许可证的施工单位或者支解发包。三是要求施工单位垫资施工，导致安全投入严重不足。四是强令施工单位抢工期、冒险作业等。五是国家和省相关法律、法规中对建设单位约束比较笼统，责任也较轻

二、说学生本届高一学生经过了三年初中课改，在心理上，他们渴望表现的欲望和自主探究的欲望比较强烈，对有兴趣的知识表现出高度地热情，并具有一定的团结协作能力，但还是应该正视一个并不乐观的现实——在写作方面，学生知识还停留在简单的记叙及表达方式综合运用上，至于巧妙构思、谋篇布局很是空白。即便已经经过高中一个学期的学习，但还是有大部分学生依然基础较为薄弱，甚至出现不知从何下笔的现象。三、说教法与学法“老师搭台，学生唱戏”１、教法：本课将安排两课时（一课时学习一课时练笔），采用 PPT 多媒体课件教学，尝试用角色扮演法、图片展示法和多媒体教学等方法，教学中应该重视学生的参与性和探究性。２、学法：学生应该充分利用多角度创设的学习情境来激发自身学习的兴趣和热情，分组讨论，小组互助等形式让学生积极自主参与、进行问题探究学习。理论依据：建构主义理论“学生是学习的中心”的阐释，教师应该做学生主动建构意义的帮助者、促进者。
人教版新课标高中物理必修1质点参考系和坐标系说课稿2篇
一、说教材《质点 参考系和坐标系》是人教版普通高中物理必修一第一章第一课的内容。本节课主要介绍了质点、参考系、坐标系的基本概念。通过本节课的学习为进一步学习后续课程起到了铺垫的作用。根据上述教材的结构和内容分析，又考虑到高一年级学生的认知结构及其心理特征，我制定了以下三维教学目标：1、知识与技能：知道质点的概念及条件；知道参考系的概念及作用；掌握坐标系的简单应用。2、过程与方法：促进学生自主学习，让学生积极参与、乐于探究、勇于实验、勤于思考，培养学生的科学探究能力。3、情感态度与价值观：通过质点 参考系和坐标系的学习，使学生了解生活与物理的关系，让学生学会用科学的思维去看待事物。根据普通高中物理课程标准，并在吃透教材的基础上，我确定了以下教学重点和难点：教学重点：质点概念的建立。只有掌握了这一点才能更加准确的理解和掌握后续教材的相关内容。

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.

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
人教版高中生物必修1能量之源—光与光合作用说课稿
1）他们在初中的生物学学习中已具备了一定的关于光合作用的基础知识，也做过“绿叶在光下制造淀粉”这个实验。2）他们具备物质转变和能量变化等相关的化学知识。3）在前面的《降低化学反应活化能的酶》一节的学习中已经学习过简单的对照实验和相关的实验设计原则，使本节课最后的实验设计得以顺利进行。4）他们具有一定的 分析问题的能力，实施问题探究教学是可行的。三、教法和学法根据上述对教材和学生的分析，本节采用以下教法和学法：1）实验法：以实验说明结论。生物学的教学就是实验的教学过程，实验的展示形式有学生分组实验、老师示范实验、动画和图片演示实验等，让实验现象说明问题，而不是直接让学生记住结论。2）问题探究教学发：以问题引发兴趣。整个教学过程要设置好问题，层层展开，层层递进，让新知识与旧知识融为一个整体，让学生在步步上升中攀登到知识的顶峰。3）比较学习法，同时采用多媒体辅助教学，解决光合作用抽象的过程。
