人教版新课标高中物理必修2能量守恒定律与能源说课稿3篇
（3）内陆和中西部城镇主要以煤和火电为主；广大农村和边远地区大多正从使用农作物秸秆等生物能源。（4）人均能源资源不足。我国是世界第三大能源生产国和第二大能源消费国，而我国能源短缺，特别是油气资源短缺已成为制约我国经济发展的重要因素。相关数据——煤炭、石油和天然气的人均资源占有量只有95t，世界平均值为209t，约是世界人均值的1/2；我国人均石油可采储量3t，世界平均值为28t，约为世界平均值的1/10。我国人均能源消费量不足1.2吨标准煤，居世界89位，不足世界人均能源消费水平的一半，仅占发达国家的1/5～1/10。其中人均消费650kg标准煤，是世界平均额的95%；人均消费石油相当145kg标准煤，为世界平均数的16.8%；人均消费天然气相当17.7kg标准煤，为世界平均数的3.9%；人均消费电力501.5kWh，为世界平均水平的25%。（5）是能源消费结构不合理，突出存在着一低两高：即电能消费比例低，非商品生物能源消费量高，一次性商品能源消费中原煤消费比重高。原煤消费达到75%，远高于26.2%的世界平均水平。
人教版新课标高中物理必修1自由落体运动说课稿2篇
学生回答的方法多样，让各小组根据自己讨论出来的方法对自己实验出来的纸带进行数据处理，并求出加速度，并且将多条纸带都进行处理，同时提醒学生对纸带的选择。接着，我会用多媒体展示重物下落实验打出来的纸带，用表格列出一段纸带上各点的瞬时速度，准确画出v-t图像，求出加速度，将结果给予学生的结果作对比，确定出正确结论。最后让学生分析总结：自由落体运动是初速度为零的匀加速直线运动，而且，多条纸带算出来的加速度的数值都接近相等，即加速度在实验误差允许范围内是相等的。引出重力加速度，介绍概念、方向及大小。（强调“同一地点”，让学生阅读教材中一些地点的重力加速度，可以了解重力加速度的大小与纬度有关，纬度越大加速度越大）。学习了重力加速度后让学生根据之前学习的匀变速直线运动公式推导出自由落体的运动规律。设计意图：让学生在学习过程中的主体地位和自主观能动性得到充分发挥，取长补短，培养了学生的实验操作能力，又使学生对自由落体运动的性质有深刻的印象，从而解决了本节课第二个难点。
人教版新课标高中物理必修1时间和位移说课稿2篇
研究一种物理现象，总是要先从现象的描述入手。机械运动作为自然界最简单和最基本的运动形态，它所描述的是物体空间位置随时间变化的情况。因此，本节学习描述质点做机械运动需要时刻、时间间隔和位移等概念。相当一部分高一学生在具体过程中难以区别时刻和时间间隔。另外，由于思维的定式，在第一次接触既要考虑大小又要考虑方向的问题时，会因不适应造成学习困难。所以，区别“路程与位移”“时刻和时间间隔”是教学的重难点所在。学习这些内容的过程与方法对学习速度和加速度可以起到奠定基础的作用。教学的对象是高一的学生，这一时期的学生处在好奇善问、创新意识强烈的青少年期。对于生活中出现的各种现象具有浓厚的兴趣。但他们的思维还停留在简单的代数运算阶段，对于矢量和矢量运算的理性认识几乎没有。且对生活中出现的时间、时刻、时间间隔等不能做出很好的区分，对时常提及的路程、距离等形成了模糊的前概念。
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。
人教版新课标高中物理必修2动能和动能定理说课稿3篇
2、教学目标根据我对教材的理解、结合学生的实际情况、渗透新课程的教学理念，为提高全体学生的科学素养，按课程标准，以促进全体学生发展为目的。从知识与技能、过程与方法，情感态度与价值观三个方向培养学生，拟定三个教学目标：知识与技能：（1）知道什么是动能。（2）正确理解和运用动能公式分析、解答有关问题。（3）掌握外力对物体所做的总功的计算，理解“代数和”的含义。（4）理解和运用动能定理。过程与方法：通过演绎推理过程，培养科学研究兴趣，领略物理学中所蕴含的严谨的逻辑关系。情感、态度、价值观：通过运用动能定理分析解决问题，感受成功的喜悦，培养学生对科学研究的兴趣。3、教学的重点和难点重点：理解动能定理、应用动能定理解决力学问题。难点：应用动能定理解决多个过程的力学问题，以及变力做功或曲线运动中的动能定理运用。
人教版新课标高中物理必修2圆周运动说课稿3篇
设计意图：通过设疑、讨论及学生的亲身体验与教师的引导，得到描述圆周运动快慢的两个物理量，也就成功的打破了学生在认识上的思维障碍，突破了物理概念教学的难点。在解决线速度和角速度的问题之后，我将引领学生学习匀速圆周运动的概念以及匀速圆周运动中线速度、角速度的特点。并引出匀速圆周运动中周期、转速的知识。为了加深学生对线速度、角速度与半径关系的认识，我设计了第三个学生体验活动：四名学生以我为圆心做圆周运动，四名学生始终并列，这时里圈同学走动不急不慢，而外圈同学则要小跑。通过学生的活动，不难发现在角速度相同的情况下，半径越大的线速度也越大。定性的得到了线速度、角速度与半径的关系。接下来让学生利用所学知识推导线速度、角速度与半径的关系。设计意图：这样就通过设疑、学生猜想、体验、推导的方式得到了结论，突破了本节课的难点即线速度、角速度与半径的关系。

新人教版高中英语必修2Unit 2 Wildlife Protection-Reading and Thinking教案二
The theme of this unit is human and nature, focusing on the theme of wildlife protection. Nature is a complex ecosystem, in which there are delicate balance between animals and plants. Because of the role of the food chain, the extinction of one species will produce influence, causing a series of chain reaction. Large scale extinction of species will have a serious and even irreversible impact on the ecosystem, resulting in immeasurable losses. Therefore, it is of great significance to protect wild species. To protect wild species is to protect human beings themselves. The motto of this unit is "when the buying stops, the killing can too,” which is a public service advertising slogan to protect wildlife. It tells people that every rhinoceros horn, every fur, every bowl of shark fin soup, every Ivory product, and every tiger bone product, etc. consumed by human beings, are innocent wild animals slaughtered behind them. The mission of wild aid is to ban illegal trade in endangered wildlife and mitigate climate change. It aims to educate the public to reduce the consumption demand for endangered wildlife products through public publicity and improve the awareness of environmental protection.1. Improve the awareness of wildlife protection by acquiring the knowledge of wildlife protection.2. Focus on environmental protection and protection of all lives.3. Analysis of the living environment of wild animals with appropriate thinking mode.4. Skillfully use the vocabulary and grammar knowledge of this unit to cultivate self-study ability according to the unit content5. Develop cooperative learning ability through discussion and other ways1. Enable the Ss to talk about the current situation of wild animals.2. Guide the Ss to summarize the main idea of each paragraph as well as the main idea of the text.

人教版新课标高中物理必修2功率教案2篇
1．用CAI课件模拟汽车的启动过程。师生共同讨论：①如果作用在物体上的力为恒力，且物体以匀速运动，则力对物体做功的功率保持不变。此情况下，任意一段时间内的平均功率与任一瞬时的瞬时功率都是相同的。②很多动力机器通常有一个额定功率，且通常使其在额定功率状态工作（如汽车），根据P=FV可知：当路面阻力较小时，牵引力也小，速度大，即汽车可以跑得快些；当路面阻力较大，或爬坡时，需要比较大的牵引力，速度必须小。这就是爬坡时汽车换低速挡的道理。③如果动力机器在实际功率小于额定功率的条件下工作，例如汽车刚刚起动后的一段时间内，速度逐渐增大过程中，牵引力仍可增大，即F和v可以同时增大，但是这一情况应以二者乘积等于额定功率为限度，即当实际功率大于额定功率以后，这种情况不可能实现。
