人教版高中生物必修1细胞分化说课稿
在讲述细胞分化的意义时，也可以用实例来解决，工厂的生产车间里不同的工人干着不同的工作，一件产品的产出需要这些工人才能创造出来，一个生物体就像一个车间一样，不同的细胞各司其职，相互合作。工人的分工是主管调解出来的，而不同细胞的出现就是细胞分化的结果，所以说，细胞的分化是生物体发育的基础。在讲到细胞全能性的时候，要多给学生举些关于细胞全能性的例子，如植物组织培养、克隆技术等等，让学生从实际的例子中真正的悟出细胞全能性的含义。此外，还要重视教材中的疑问，适当对题目进行引申,使它的作用更加突出，有利于学生对知识的串联、积累、加工，从而达到举一反三的效果。怎样来解释细胞的全能性呢？这主要以讲授法来解释了，细胞全能性的体现需要在组织或器官离体后才能体现出来，每个细胞都包含着生物体的全套遗传基因，通过基因选择性的表达，使离体的组织或器官通过分裂和分化逐渐发育成完整的植株。

3、遗传密码的特点 连续性、简并性、通用性5、课堂练习6、作业布置假如，我们利用(ACU)n核苷酸长链合成了含有苏氨酸的多肽，那么苏氨酸可能的密码子有哪些？如何运用实验方法确证苏氨酸的密码子究竟是什么？七、教学反思1、教材中丰富的科学史料，是我们在课堂上进行探究性学习活动的良好素材，教师要整理和运用好。千万不要低估学生的思维能力，当学生的思维能力被你想方设法激发出来的时候，你会发现他们的创造力是无穷的。2、探究性学习的目的并不仅仅是问题的解决，更重要的是在探究过程中体验和获取科学研究方法，培养合作与分享的精神以及实事求是的科学态度，锻炼思维能力，提高科学素养。3、学生是学习的主体，教师是引导者。我们要采取措施让学生积极主动地参与到学习活动中来，通过他们的思考、讨论、争辩、合作等活动来获取方法，建构知识。

3、拓展延伸，启迪心智，创设课堂训练营。三、说学法1、纸上得来终觉浅，圈点、勾画、批注法，学好文言基本功。2、自主合作加探究，眼耳口脑手并用，破疑解难在其中。四、说课时安排《鸿门宴》篇幅较长，文言知识较丰富，文章内涵丰厚，因此我设计用五课时教学本文。第一课时：了解作家作品，积累文言知识，感受作者隐忍发愤的著书精神（初读）第二课时：理清故事情节，概括人物形象，学习客观地评论历史人物，（熟读）第三课时：进一步梳理文言知识，精读课文，要求读透。（精读）第四课时：通过对人物、事件的赏析，加深学生对人物的理解，锻炼学生的开放性思维，由学生自主认识到人物的性格，悲剧的原因等问题。（赏读）第五课时：补充课本教学内容：同学生一起阅读古今关于刘邦项羽的一些篇章：让学生投入进来，把握自己眼中的项羽。（展读）在文言文学习的过程中，采取五步学习法：初读-熟读-精读-赏读-展读（板书）
人教版高中语文必修1《优美的汉字》说课稿
明确：（1）结绳记事说。原始记事的一种方法。人类在没有发明文字或文字使用尚不普遍时，常用在绳索或类似物件上打结的方法记录数字，表达某种意思，用以传达信息，处理事件。 （2）书画说。（3）仓颉造字说。中国自古就有仓颉造字之说。文字的发明是人类发展史上一件石破天惊的大事，它将人们的思维、语言、经验以及复杂的社会现象记录下来，使文化得以传播交流、世代传承。2、汉字的形体：中华民族五千年的历史中，汉字的演变，从甲骨文－－金文－－大篆－－小篆－－隶书－－草书－－楷书－－行书，字形由象形到点横竖撇捺的方块字，经历了漫长的岁月。其中凝聚着民族的智慧，也体现出汉字逐步完善的过程，凸显其方方正正、四平八稳的特点。汉字又是一种文化的体现，那些经过艺术处理的汉字或跳起了拉丁舞、有的如同酒醉的成龙打起了醉拳，更是让我们感到的是在欣赏汉字在纸张上跳舞，所以：书法是“纸上的舞蹈”。请大家看到书上的相关内容，注意每一种形体的汉字的载体是什么，其功能又有什么不一样。

人教版高中历史必修2大众传媒的变迁说课稿
教学内容与分析本课内容是大众传媒的变迁，首先解题，了解什么是大众传媒。大众传媒就是传播大众信息的媒体，进入近代社会以来，人与人之间的联系变得越来越密切，社会化程度大大加深，需要有一种大众化、传播速度快、传播范围广的媒介作为人与人之间进行信息沟通的渠道，人类社会的传媒手段应运而生，可由学生总结出有哪些主要的方式。报刊、影视、广播，这三种大众传播媒体的依次出现，给人们的生活方式带来了巨大的变化，被称为三大媒介。由于互联网同报纸、广播和电视三大媒介一样，具有传播信息的功能，所以被称为“第四媒介”，即“网络媒介”。通过本节课的学习使学生了解中国近代社会生活的变化，体会历史和时代发展的必然性，能够站在发展的角度、用历史的眼光思考问题。

人教版高中历史必修3辉煌灿烂的文学说课稿
教师：不同的时代造就了不同风格和不同精神内容的诗词，请同学们回顾必修一和必修二两宋中央集权的加强和经济的发展状况。学生：回忆回答。教师：请同学们结合时代背景和词的特点理解词为什么能够成为宋代文学的主流形式和标志？学生：两宋时经济重心转移到了南方，商业发展打破了时间和空间的限制，城市繁荣，市民数量不断增加。词的句子长短不齐，便于抒发感情，并且能够歌唱，更能适应市井生活的需要。于是，词成为宋代文学的主流形式和标志。教师：宋代文人地位提高，宋词就是一个个时代的画卷：大宋的悲欢离合都写在了里面。除了词之外，宋代民间还兴起了一种新的诗歌形式，即散曲。学生：回答散曲的发展阶段及特点、元曲的含义、特点。教师：在中国古代诗歌辉煌发展的同时，也产生了供人们闲来无事消遣的小说。

人教版高中生物必修1细胞的癌变说课稿
5．5癌症的预防作为本节最重要内容，且与生活息息相关，我采用老师引导、学生讨论总结的方法进行教学。从生活各方面总结出保健良方 ，既对知识有很好应用，又体现对生命的热爱。此时，本节课达到高潮，同学们意气风发，热烈讨论，实现本节课的教学目标。5．6 癌症的治疗通过讲述癌症治疗方法的副作用，激发学生探究生物学欲望，激励学生立志除癌。 在此，我选用一则关于一名癌症晚期病人运用心理疗法成功战胜癌症的故事，在于对不同层次的学生进行多方面启发教育，体现面向全体学生的课程理念。5．7 愉悦总结，及时反馈本节知识点零散，我将带领学生回忆浏览本节内容，使零散知识点系统化。在课堂反馈环节，我通过简单练习采用分组竞答的方式把握学生对知识的掌握程度，并给予表现突出的学生适当奖励，这是本节课第三个亮点。竞答既使课堂显得紧凑、集中，又有利于形成学生的竞争意识，还使得学生的知识得以巩固应用。
人教版高中生物必修1细胞的衰老与凋亡说课稿
4、最后从生物的寿命引入，探讨细胞的死亡。强调细胞死亡有两种形式。(1).细胞坏死，它是由某些外界因素造成细胞急速死亡，是一种被动性死亡；(2).细胞凋亡，这是一种由特定基因控制的主动性死亡。细胞坏死与细胞凋亡在形态学和生物化学上有着明显的区别。细胞凋亡有广泛的生物学意义，比如胚胎发育期手的发育如果没有细胞的调亡就不会有纤细的手指；如果没有正常的细胞调亡，蝌蚪的尾部就不会消失，它将永远不能变成青蛙……。正常的细胞调亡还肩负着维持各种组织器官固有体积和形态的功能；还会使机体内异常的细胞得到及时清除，去处潜在的隐患；例如癌症就是异常的细胞没有及时死亡的结果……。因此细胞的正常死亡是生物体的一种非常重要的调节机制，是机体平衡细胞增殖，调节机体细胞树木恒定的方式，是必不可少的生命过程。（15分钟）5、课堂小结，可以把课堂传授的知识尽快地转化为学生的素质；简单扼要的课堂小结，可使学生更深刻地理解政治理论在实际生活中的应用，并且逐渐地培养学生具有良好的个性。
