人教版高中生物必修3第二章第四节《免疫调节》说课稿
（四）、活动交流，体验科学通过资料分析讨论以下三个问题：1、你知道爱滋病的传播途径吗？2、如何预防爱滋病？3、我们应如何对待爱滋病患者？面对艾滋病我们能做些什么？从而进入情感态度的教育。除此之外，我还设计一个开放性的作业“向全社会为关注艾滋病设计一个宣传广告”（形式不限，漫画、板书、倡议书等），让学生把爱心付诸于实际行动。在此基础上引出“免疫学的应用”从免疫预防、免疫治疗、器官移植三个方面讲述，让学生充分体验到知识和社会生活的紧密联系，让他们不在感到科学是那么的遥远，而是可爱的有用的。通过交流，让同学们体会到合作的魅力和重要性，进一步培养合作意识和合作能力。最后我设计一个资料搜集，让同学们选一个感兴趣的主题利用电脑在网上搜集有关资料。主题：1、你知道世界艾滋病日吗？历年的主题是什么？开展世界艾滋病运动有什么意义？
人教版高中地理必修1第二章第四节全球气候变化说课稿
（一）教材的地位与作用本节教材包括三方面的内容，（1）全球气候在不断变化之中。（2）全球气候变化的可能影响。（3）气候变化的适应对策三方面说明气候变化及其对人类活动的影响。从标准的要求看，学习的重点不在全球气候变化本身，而是把全球气候变化看作是客观存在的事实，从而探讨全球气候变化对地理环境及人类活动的影响。从资料中可以看出本节教学内容涵盖的时空跨度非常大，思维的链索很长很广，许多问题涉及到学科的前沿及人类所关注的热点，因此，本节课对学生而言既有趣味性，又有挑战性。 （二）教学目标(1)知识与技能目标：1.通过全球气候的长期演变图，学生了解全球气候处在波动变化之中。2.通过资料认识全球气候一直处于变化之中并呈现一定变化周期，了解全球气候变化对地理环境及人类活动的影响，能够提出一些气候变化的适应对策。
人教版高中地理必修1第二章第一节冷热不均引起大气运动说课稿
4、【自主探究】巴山夜雨的成因③材料三：三国时期，诸葛亮于农历6月的一天，在葫芦峪设下伏兵，打算用火攻全歼司马懿。这一天，晴空万里暑热难耐，真乃火攻之良机。诸葛亮依计将司马懿之众诱入谷中……然而，正当大火冲天，司马懿全军行将覆灭之时，一场大雨不期而至，大雨浇灭了诸葛亮扶汉反魏的壮志，使他喊出了“谋事在人，成事在天，不可强也”的千古悲歌。【设计理念】前后呼应，发散思维。通过自主探究，学生各抒己见，完成对热力环流整个知识框架的一个总结，既考查了学生的课堂学习效果，又锻炼了学生知识的迁移能力，并认识生活中的地理规律，用生动的语言拉近学生与大气理性知识的距离，体会到地理学科的重要性。【提问】如果将白天换成夏季，将夜间换成冬季，情况又会怎样？城市与郊区之间也存在着热力环流——城市风，它们是怎样形成的？了解城市风的出现有何重要意义？如果地球上在赤道和两极之间存在热力环流，这个热力环流应该怎样？这几个问题，请大家课后慢慢思考。
人教版新课标高中物理必修1牛顿第二定律说课稿2篇
进一步引导学生思考利用数学知识可写成等式F=kma学生很自然就会思考比列系数K应该是多少？通过教师引导学生举例各国长度单位不同（如英国：英里、码、英尺、英寸；中国：市里、市丈、市尺、市寸、市分 ）导致交流不便。为了适应各国交流需要国际计量局规定了一套统一的单位，称为国际单位制 。取不同的单位制K是不同的，为了简洁方便，在选取了质量和加速度的国际单位（Kg, m/s2)时规定K=1。那么就有；F=ma为了纪念牛顿，就把能使1kg物体获得1m/s2加速度的力称做一牛顿，用符号N表示问题：实际物体受力往往不止一个，多个力情况应该怎么办呢？平行四边形法则进一步引导学生得出牛顿第二定律更一般的表达式: F合=ma思考.讨论我们用力提一个很重的箱子，却提不动它。这个力产生了加速度吗？要是产生了，箱子的运动状态却并没有改变。为什么？
人教版高中历史必修2第一次工业革命说课稿2篇
3、工业革命引起社会关系变化——形成两大对立的工业资产阶级和无产阶级工业资产阶级和工业无产阶级成为社会的两大阶级。工业资产阶级获得更多的政治权利，各国通过改革，巩固了资产阶级的统治。 4、工业革命推动资产阶级调整内外政策——自由主义与殖民扩张对内，希望进一步摆脱封建束缚，要求自由经营、自由竞争和自由贸易。重商主义被自由放任政策所取代。对外，加快了殖民扩张和殖民掠夺的步伐。三、世界市场的基本形成1、原因条件（1）工业革命的展开使世界贸易的范围和规模迅速扩大1840年前后，英国的大机器工业基本上取代了工场手工业，率先完成了工业革命，成为世界上第一个工业国家。之后，法国和美国等国也相继完成工业革命。随着工业革命的展开，资产阶级竭力在全世界拓展市场，抢占原料产地，使世界贸易的范围和规模迅速扩大。
人教版高中历史必修2第二次工业革命说课稿2篇
②内燃机的发明推动了交通运输领域的革新。19世纪末，新型的交通工具——汽车出现了。1885年，德国人卡尔·本茨成功地制成了第一辆用汽油内燃机驱动的汽车。1896年，美国人亨利·福特制造出他的第一辆四轮汽车。与此同时，许多国家都开始建立汽车工业。随后，以内燃机为动力的内燃机车、远洋轮船、飞机等也不断涌现出来。1903年，美国人莱特兄弟制造的飞机试飞成功，实现了人类翱翔天空的梦想，预告了交通运输新纪元的到来。③内燃机的发明推动了石油开采业的发展和石油化学工业的产生。石油也像电力一样成为一种极为重要的新能源。1870年，全世界开采的石油只有80万吨，到1900年猛增至2 000万吨。（3）化学工业的发展：①无机化学工业：用化学反应的方式开始从煤焦油中提炼氨、笨、等，用化学合成的方式，美国人发明了塑料，法国人发明了纤维，瑞典人发明了炸药等。
人教版高中语文必修3《杜甫诗三首 咏怀古迹》说课稿2篇
第三，说教学重点和难点。根据课程标准的具体要求、学生实际和社会实际以及教材的逻辑结构和教学体系，我认为本课的重难点是以下几个方面。教学重点：1．理解王昭君的形象2．深入理解杜甫在诗中的情感教学难点：理解寓意，把握主旨。第四，说教法与学法。教法：根据课文特点和学生实际情况，以诵读法（示范朗读、学生齐读）、问题探究法、点拨法、讨论分析法进行教学。首先激发学生学习本文的兴趣；然后引导学生反复吟哦诵读，在读的过程中质疑、思考、品析、鉴赏；最后在教师适当的点拨下，在集体的热烈讨论中，理解作者的感情，得到新的认识。（解说：使学生在教师的主导下围绕中心议题发表各自的意见，相互交流，相互启发，相互争议，激发他们主动去获取知识，培养健康情感。）
人教版高中语文必修3《杜甫诗三首 秋兴八首》说课稿2篇
师：“两开”是什么意思啊？注解里是怎么说的？第二次开，也就说他在这个地方已经待了两年了，这里是他回家的路途中，是不是？路途中他停留了两年时间。好的，你先请坐。你觉得残菊不能两开，在理解上好像存在一些误差。赵勇：因为菊花古往今来代表着对家乡的思念。师：菊花代表对家乡的思念？（下面学生齐笑）这种说法牵强了些，菊花在古代象征着高洁，梅兰竹菊是四君子嘛。赵勇：写这首诗时，他已经打算回故乡了，所以不应该写“残菊”，写“残菊”的话……师：事实上，他回不了故乡。好的，请坐。再想想，“残菊”意味着什么？破败。“丛菊”呢？茂盛。那这里说“两开他日泪”，“两开”是什么意思？开了两了次了，这说明他在这里已经待了两年了。那“他日泪”又是什么意思？赵勇：应该是他看到这里的菊花开得这么茂盛，就想到了故乡的菊花也是开的茂盛的时候。如果是“残菊”的话，那故乡的菊也会开得很残败。（下面学生齐笑）
