北师大版小学数学五年级上册《谁打电话时间长》说课稿
（1）、创设情境，提出数学问题。出示主题图，中秋节到了，淘气和笑笑通过打电话的方式来表达对远方亲人的思念，从这幅图中你能得到哪些数学信息，能提出什么数学问题。学生很容易就找到数学信息“笑笑打国内长途，每分钟0.3元，共花5.1元；淘气打国际长途，每分钟7.2元，共花54元。”根据这些信息你能提出哪些数学问题呢？学生可能会说“笑笑打电话的时间是多少分？淘气打电话的时间是多少分？”还有的同学会提出“笑笑和淘气谁打电话的时间长？”等等，你能估一估淘气和笑笑谁打电话的时间长吗？（2）估算谁打电话时间长？通过估算，培养学生的估算意识，提高估算能力，丰富学生的素养，发展数感。在这里我分为三步：首先让学生说说是怎样估算的；其次指名学生说说估算的过程；最后评价和鼓励估算方法的合理性。

2．辩证的否定(1)辩证的否定是事物的自我否定。事物内部存在着肯定方面和否定方面，它们既对立又统一。最初，肯定方面处于支配地位，否定方面处于被支配地位。在这种情况下，事物就被肯定着。但是，在矛盾双方的斗争中，否定方面总会由弱变强。一旦否定方面由被支配地位上升为支配地位，事物就转化到了自己的对立面，实现了对事物的否定。事物最终之所以被否定，根源在于事物的内部，是事物内部的否定因素战胜了肯定因素。因此，事物的否定是自我否定。(2)辩证的否定是事物发展的环节和联系的环节。所谓发展，是指新事物的产生和旧事物的灭亡。而实现这一过程必须要对旧事物进行否定，否定实现了事物由旧质向新质的飞跃。新事物在否定旧事物时，并不是把旧事物全盘抛弃，一笔勾销。旧事物是新事物的母体，新事物从旧事物那里脱胎而来，新事物是在批判地继承旧事物中的一切积极的有生命力的因素的基础上发展起来的。这样，在新旧事物之间就存在着必然的联系。
人教版高中政治必修4综合探究：走进哲学，问辩人生教案
1．根据课程标准的要求。本单元的主题是“生活智慧与时代精神”，课程标准的要求主要是引导学生“思考日常生活富有哲理的事例，感悟哲学是世界观的学问，能够开启人的智慧”，“解释哲学的基本问题”，“分析实例，说明真正的哲学是时代精神的精华，明确马克思主义哲学在人类认识史上的重要地位”。这些问题，综合起来就是使学生明确哲学与我们生活的关系，认识学习哲学特别是马克思主义哲学对我们人生的作用。因此，探究本问题有助于学生更好地理解本单元的内容，完成本单元的教学目标。2．根据学生的实际需要。学习哲学特别是马克思主义哲学，可以帮助学生树立正确的世界观、人生观和价值观，这也是学习哲学的主要目的。但在学生中还不同程度地存在着“哲学与我们的生活很远”、“哲学与我无关”、“哲学对我将来从事自然科学的研究没有什么用处”等认识，这些都影响着学生对哲学学习的态度和哲学作用的发挥。设置本探究问题，有助于帮助学生澄清这些模糊认识。
人教版高中政治必修4综合探究：坚定理想，铸就辉煌教案
理想扎根在实践的土壤中理想当然是重要的，但是不能把理想当成幻想或空想，理想必须扎根在实践的土壤中。青年人充满激情，这是非常重要的。古人有句话：“哀莫大于心死”。最大的悲哀就是没有追求，就像一团火焰熄灭了一样，即使到了我这个年纪也不能“哀莫大于心死”。青年人都有很高的激情，这是很好的。但是青年的激情往往不大稳定，过去人们说青年人的热情是“三分钟的热度”。这句话不一定准确，但青年人在这一点上应该有一个正确的认识。记得我大学毕业时，对于走向社会、走向生活充满了幻想，认为生活中的一切都是美好的，是典型的理想主义者，因此，对自己不能正确的估价，好高骛远，只愿做大事，不愿也不注意从小事积累。列宁说过，大事是由小事积累而成的。我当初毕业时，一方面充满了激情，另一方面也确实过高地估计了自己。

7．我国人力资源开发利用面临四大挑战在全面建设小康社会进程中，我国人力资源开发与利用面临着以下四个方面严峻挑战。(1)劳动力供给高峰的到来加剧了劳动力供求总量矛盾。持续的经济增长和人口计划生育控制，使得我国人口再生产在不到30年的时间内完成了从“高出生率、低死亡率、高自然增长率”的类型到“低出生率、低死亡率、低自然增长率”类型的转变，人口在日增长率已经连续数年低于千分之十。然而，庞大的人口基数及其低速增长仍对中国未来经济增长和社会发展带来巨大的就业压力，大量预测表明，未来20年是中国人口数量增长和劳动力供给的高峰时期。20世纪90年代以来，中国劳动年龄人口比重(16—59岁年龄组)由1990—1996年期间的61％～62％上升到1999年的63．2％。这种趋势将会持续到2020年左右达到峰值，直到老龄化进程抵消了数量增长效应，劳动年龄人口的比重才会趋于下降。到2020年，中国劳动年龄人口将由2000年的8．61亿上升到10．04亿，平均每年新增劳动力715万人。

在数学上，0这个数是解决记数和进位问题而引进的概念，由于它不能表示实在的东西，很长时间人们不把它看作是一个数。认为0是无，是对有的否定。从唯物辩证法的观点看，这种否定不是形而上学的简单否定，而是具有丰富内容的辨证否定。辨证的否定是发展的环节。0是从无到有的必经之路，是连接无和有的桥梁。0又是正数和负数之间的界限，它既否定了任何正数，也否定了任何负数，是唯一的中性数。但它又是联结正数和负数的中间环节。没有0，负数就过渡不到正数去，正数也休想发展到负数来。数学中的0是对任何定量的否定。如果没有这一否定，任何量的发展都无从谈起。这个否定不是一笔勾销，而是扬弃。因为它克服了任何定量的有限性，成为其发展的环节。在现实生活中，0作为辨证的否定，也体现出联系和发展的性质。如0度不是没有温度，而是非常确定的温度。

南极大地的水陆交接处，全是滑溜溜的冰层或者尖锐的冰棱。企鹅没有可以用来攀爬的前臂，也没有可以飞翔的翅膀，如何从水中上岸？纪录片《深蓝》展示，企鹅在将要上岸之时，要从海面潜入海中，沉潜到适当的深度，借用水的浮力，迅猛向上，飞出一道弧线，落于陆地之上。企鹅的沉潜是为了蓄势，看似笨拙，却富有成效。人生又何尝不是如此？沉潜绝非沉沦，而是勇敢、智慧、自强。如果我们在困难面前能沉下气来，不被“冰棱”吓倒，不被浮华迷惑，专心致志，自强不息，积聚力量，并抓住恰当的机会反弹向上，毫无疑问，我们就能成功登陆!反之，总是随波浮沉，或者怨天尤人，注定就会被命运的风浪所玩弄，直至精疲力竭。结合上述材料，运用《生活与哲学》知识对“价值观是人生的重要向导，有价值观的人生才是更美的人生”加以评析。7、有两名畜牧兽医专业毕业的大学生应聘到农村养猪场担任技术总监后，大力推广使用生态养猪法和中草药防疫技术，使养猪场步入了良性发展轨道。

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.

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.
