人教版高中生物必修1生命活动的主要承担者—蛋白质说课稿
第五，蛋白质的功能。蛋白质功能具有多样性，由学生对照教材，进行总结。为什么蛋白质有那么多功能呢？根据我们学习生物学的经验可知道：生物的结构决定功能。再要求刚才的那四个同学上台组合多肽链。以不同位置组合，就会形成很多种多肽链，进而形成很多种蛋白质。每一种蛋白质都有其特定的功能，所以蛋白质具有多样性，其功能也具有多样性。第六，总结。蛋白质是细胞和生物体中重要的有机化合物，是一切生命活动的主要承担者。蛋白质的多样性是形形色色生物和绚丽多彩生命活动的物质基础。（可以由学生总结）第七，教学评价。由于只有一节课时间，课堂上对重点、难点知识的解析还不能做到举一反三的深度，因此尽管学生课堂反应热烈，对知识点的接受程度也达到了预期的要求，但在做课后练习时，也会出现一些问题。所以传统的讲练结合还是要结合起来运用才能取得更好的效果。为此本节内容需要2课时来完成。
人教版高中生物必修1生物膜的流动镶嵌模型说课稿
二、流动镶嵌模型的基本内容1、膜的成分2、膜的基本支架3、膜的结构特点4、膜的功能特性设计意图：我根据板书的“规范、工整和美观”的要求，结合所教的内容，设计了如图所示的板书，使学生对本节课有一个整体的思路。八、教学反思：本节课我创设了问题情境来引导学生主动学习，利用了多媒体信息技术激发学生的学习热情，调动了学生的积极性，成功实现预期的教学目标。体现了学生为主体地位的新课程理念。启发式、探究式的教学方法以及由教师指导下的学生自主阅读、合作交流的学习方法把学生从死记知识的苦海中解救出来。初次的尝试还存在一定的缺陷，学生不能够很好的把知识和习题联系，只是把他所知道的知识简单罗列，不能够体现出能力的训练。在上课中发现学生比较腼腆或拘束，声音比较小，表达不能到位。尽管本节课存在诸多不足之处，但是也让我看到了闪光点：学生比较欢迎这样一堂自己是主角的课堂。
人教版高中生物必修2现代生物进化理论的主要内容说课稿
什么因素可以阻止种群间基因交流呢？由此可引出隔离的概念。学生初步理解隔离的概念之后，可以安排学生讨论隔离的各种可能的方式，教师归纳出隔离的类型。然后组织学生阅读分析教材中的“资料分析”，组织讨论“资料分析”中提出的几个问题。最后教师应强调，一般情况下，地理隔离是生殖隔离的先决条件，生殖隔离一旦形成，原来属于一个物种的两个种群，就成了两个物种。关于“共同进化与生物多样性的形成”内容的教学，可以学生自学为基础，教师提出一些具有启发性的问题，师生共同归纳总结的方式推进教学过程。使学生理解共同进化的含义，无机环境的变化、无机环境的复杂化和多样化、有性生殖的出现和生态系统结构的复杂化和多样化对生物多样性形成的作用。最后，组织学生讨论生物进化理论在发展。
人教版高中生物必修2现代生物进化理论的由来说课稿
一,说教材1. 教材的地位和作用本章课程的核心是介绍现代生物进化理论.生物进化理论的发展和其他科学理论的发展一样,不是简单的新理论对旧理论的否定和排斥,而是新理论对旧理论的修正,深入和扩展.从拉马克的进化学说到达尔文的自然选择学说,以及现代进化理论的由来,大体都走过了这样的轨迹.这些应该成为处理本节教学内容的基本脉络.本节内容包括:拉马克的进化学说,达尔文的自然选择学说和达尔文以后生物进化理论的发展,其中重点是达尔文的自然选择学说.生物进化论不仅是生物学中具有重要地位的基础理论,也是对人们的自然观和世界观有着重要影响的理论.学生通过本章内容的学习,不仅可以了解生物进化理论在达尔文之后的发展,进一步树立生物进化的观点和辩证唯物主义观点,而且能够通过学习进化理论的发展过程,加深对科学本质的理解和感悟.

人教版高中生物必修3第三章第一节《植物生长素的发现》说课稿
（5）根据实验的第五部分——验证性实验结果，证实了达尔文关于植物向光性运动原因的假说――确实存在一种物质致使胚芽尖端产生了向光运动。这样通过多个实验的多媒体演示过程，强化学生的思维，最终在学生的大脑中形成科学研究过程的”条件反射”。为了使学生初步学会”设计对照实验的方法”，首先也利用多媒体的演示实验，并在其中特意设置一些”陷阱”，通过多次”请学生进入‘陷阱’”，来强化设计实验时应该控制的变量问题，从而在学生的认知领域里初步构建出设计对照实验的知识体系。3、归纳总结1934年，荷兰科学家郭葛等人从植物中分离出了这种能使植物产生向光性的物质，并确定它就是吲哚乙酸。这就真正从化学物质的角度证实了达尔文的假设。在能够从植物体中分离提取出生长素之后，要想知道：除了能使植物产生向光运动之外，生长素对于植物的器官还有什么作用？可以采用哪种方法来进行试验？
人教版高中生物必修3第五章第五节《生态系统的稳定性》说课稿

人教版高中生物必修3第五章第四节《生态系统的信息传递》说课稿
教师通过引导学生看课本的“资料分析”，要求学生从中得出生态系统中的信息传递在生态系统中的作用。学生通过分析、讨论可以得出结论，这时教师要适时的点拨，给予小结，并引导学生站在整个生态系统的角度去分析信息传递，并和能量流动、物质循环联系在一起，说明它们都是生态系统各组分必不可少的一部分，同时指出信息传递是长期的生物进化的结果。学生了解了生态系统中信息传递的作用后，教师适时进行话题的转移，“我们学习信息传递，是为了更好的利用它，谁能说出信息传递在我们生产和生活中应用方面的例子”？学生们这时就开始讨论了，他们可能做不出正确的回答，但他们却能举出生活中有关信息传递的许多例子。讨论几分钟后，让看看信息传递在农业生产中有哪些应用吧？使教学回归课本，使知识得以沉淀，形成自己牢固的知识体系。（依时可以安排学生自学）

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。
