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2探究弹性势能的表达式说课稿4篇
设疑自探：一个压缩或拉伸的弹簧就是一个“储能器”，怎样衡量形变弹簧蕴含能量的多少呢？弹簧的弹性势能的表达式可能与那几个物理量有关？类比：物体的重力势能与物体所受的重力和高度有关。那么弹簧的弹性势能可能与所受弹力的大小和在弹力方向上的位置变化有关，而由F=kl知弹簧所受弹力等于弹簧的劲度系数与形变量的乘积。预测：弹簧的弹性势能与弹簧的劲度系数和形变量有关。学生讨论如何设计实验： ①、用同一根弹簧在几次被压缩量不同时释放（劲度系数相同，改变形变量），观察小车被弹开的情况。②、分别用两根弹簧在被压缩量相同时释放（形变量相同，劲度系数不同），观察小车被弹开的情况。交流探究结果：弹性势能随弹簧形变量增大而增大。随弹簧的劲度系数的增大而增大。
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

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。

2、学生分析 九十年代初期出生的孩子，生活在一个充满活力的时代，张扬个性成为他（她）们的主旋律。面对这一时代的学生，沟通需要用心、用技巧，那也是一门艺术。高中学生的心理日趋成熟,有一定的知识积累,且比较丰富;语言逻辑性强,有较强的参与意识,求知欲望及表现欲望。学生主体参与的充分，表现在其主动性，积极性得到极大的调动。这与教师的主导作用是分不开的。本课教案就是要引导学生自己先阅读书本、独立思考、激发学生思维，引导学生各抒己见，让学生自己得出解答问题的结论，不追求答案的唯一。充分体现了读书是一种个体行为，每个学生有不同的体验。教师应跳出教案的问题模式，和学生一道去创造地发现问题、分析问题、解决问题，在成功中寻找快乐、在快乐中更加成功。同时特别注重创设的情景的选择性，有针对性和实效性，引导学生们积极、主动参与，使他们的潜能、智慧得出充分挖掘、展示。只有当学生们在课堂上表现出来的独特的、有创意的设计见解，学生主体参与和教师主导二者完美结合，才能表明该课的设计卓有成效。

人教版高中历史必修3文艺复兴和宗教改革说课稿2篇
师：在科学发展过程中，前一个理论体系的不完善之处，往往是新的研究和新的发现的突破口。开普勒之后，意大利天文学家伽利略创制了天文望远镜，用更加精确的观察继续发展和验证哥白尼创立的新天文学理论。除了用望远镜进行天文观察以外，伽利略还开始进行自然科学的实验研究，哪位同学能给大家讲一讲伽利略在比萨斜塔上所作的关于物体自由下落的实验？生：（讲述这一实验）师：所以，伽利略在科学方面更加重要的贡献是奠定了近代实验科学的基础。（2）实验科学和唯物主义师：伽利略从实践上开辟了实验科学的方法，而英国唯物主义哲学家培根则从理论上阐述了实验科学的方法——归纳法。培根和伽利略同被称为实验科学之父，培根还有一句影响深刻的名言：“知识就是力量”，表明了他注重知识，尊崇科学的精神。我们再来概括一下意大利哲学家布鲁诺的唯物主义思想，是否有同学可以简述布鲁诺的生平事迹？

2、文化反作用经济政治师：经济政治决定文化，那么，文化不是被动消极的呢？生：思考回答：文化反作用经济政治，不同的文化对经济政治的影响不同。师：文化反作用经济政治，对社会发展有重要影响。文化反作用表现在，文化可以为经济政治的发展，对社会的发展，提供方向保证、智力支持和精神动力。（1）文化反作用的体现。师：现代民主国家中，世界民主的先驱是英国，但英国却有国王，亚洲民主的先驱是日本，但日本却有天皇，其一个重要原因是文化的影响。这说明什么？生：思考发言……师：不同民族的文化，影响不同民族和国家的历史和发展道路。师：中东地区一直以来都是世界热点地区，如巴以冲突、伊拉克战争、阿富汗战争、基地组织等，其一个重要原因是宗教文化的冲突。这说明什么？生：思考发言……师：不同文化的冲突，影响社会的和谐安定和世界的和平安宁。
人教版高中历史必修1辛亥革命教案2篇
①从政府人员组成看，南京政府是一个以资产阶级革命派为主体的政府。②从政府颁发的法令和措施看，这些法令体现了资产阶级民主革命的要求，对于发展民族资本主义经济、资产阶级民主政治和文化教育以及改革社会风气，都起了积极作用。③从颁布的《中华民国临时约法》看，宪法体现了三权分立的政治体制，体现了资产阶级民主主义的要求，是中国历史上第一部资产阶级民主宪法，具有反封建专制制度的进步意义。（2）从南京临时政府的内外政策分析南京政府的根本弱点①未彻底地反封建。它没有采取比较彻底的反对封建主义的措施，特别是对封建统治的基础——地主阶级土地所有制没有触动，这样，南京临时政府也就不能真正地把广大人民群众动员起来，因而缺乏真正的群众基础。

This teaching period mainly deals with grammar “restrictive relative clauses.” To begin with, teachers should lead students to revise what they have learned about the relative pronouns and relative adverbs. And then, teachers move on to stress more special cases concerning this grammar, such as the “preposition+ relative pronouns which and whom” and cases where we can omit the relative pronouns. This period carries considerable significance to the cultivation of students’ writing competence and lays a solid foundation for the basic appreciation of language beauty. The teacher is expected to enable students to master this period thoroughly and consolidate the knowledge by doing some exercises. 1. Guide students to review the basic usages of relative pronouns and adverbs of attributive clauses.2. Lead students to learn to use some special cases concerning restrictive relative clauses flexibly.2. Enable students to use the basic phrases structures flexibly.3. Strengthen students’ great interest in grammar learning.1. Help students to appreciate the function of relative pronouns and adverbs of attributive clauses in a sentence2.

The theme of the reading and thinking is about “Understanding how a problem was solved”.The Listening & Speaking & Talking is about international co-work to protect the Mount Tai, in which the students from seven countries came up with many solutions even create the Mount Tai App. This section aims at showing how to solve a difficult and even tough problem about protecting the cultural heritage by the international co-work. So in this section, cultivating students’ international awareness is very clear and important. Concretely, with the economic development, how to balance the protection of cultural relics and social development is a big challenge for human. In the 1950s, the Egyptian government wanted to build the Aswan Dam across the Nile to control floods, produce electricity and water farms. But the proposal led to protests because it would destroy a lot of cultural relics. The Egyptian had no choice but ask the UN for help. Therefore, a international cooperation about how to protect the cultural relics began, which involved the time length about 20 years and a large amount of fund. Then, the problems was solved. 1.
