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.

六、说教学反思由于本节内容抽象复杂, 插图多, 涉及的物质种类也比较多，应要求学生做好课前预习。教学中，在处理主干知识和侧枝内容的关系时，要做到合理分配时间，明确不同内容的教学要求。教师要注意将知识及时进行归纳、比较和总结。要让学生了解各个知识点间的内在关系，又要能简洁、清晰地概述转录和翻译的过程。教师在备课时，一定要仔细分辨并揣摩插图所表达的意思，并能将不同的插图内容与教学流程有机地结合起来。在对插图的处理上，还应分清主次和轻重。教材在呈现教学内容时，采用图文并茂的方式来揭示转录与翻译的动态过程。因此，教师不仅要利用插图达到形象和直观的教学效果，还应配合教材中的文字描述作深入浅出的讲解，使文字信息与图形信息结合起来，让学生感知到基因的表达是一个多层次的、动态的、相互协调和配合的过程。尽可能利用多媒体课件进行教学。多媒体课件可以形象、生动地反映基因表达的过程，这是纸质教材难以做到的。
人教版高中地理必修2南京的自行车是多了还是少了说课稿
在学生回答的基础上进行归纳小结：发展城市公共交通? 明确道路分工? 合理规划停车场? 减少出行距离? 错开出行高峰? 加大城市道路建设? 进行科学合理的交通管理，重视智能交通系统的建设提问：这组同学在幻灯片中提到城市环境污染源主要有哪些？城市交通环境问题除了交通工具的尾气排放带来大气污染外，还会给城市环境带来什么问题？这组同学基本同意自行车多是加剧南京空气污染的间接原因，你同意他们的观点吗？在学生回答的基础上，教师进行归纳小结：自行车是一种绿色交通工具，既环保又经济。只有当它在某些机动车和非机动车不分的地段，影响车辆行驶速度的时候，它才可能成为加剧空气污染的间接原因。那么我们针对交通工具对环境造成的影响，除了这组同学提到的三点解决措施以外，我们还有什么要补充的解决方法吗？

（三）教学重、难点1、教学重点：结合课文，了解演讲辞针对性强、条理清楚、通俗易懂、适当的感情色彩等特点。2、教学难点：深入理解文章内涵，联系现实，体会本文的现实意义二、说学情高中学生在初中阶段已经接触过演讲辞了，对演讲词的特点已经有了一些基本的知识，因此本轮的教学应该让他们在此基础上有所提高。本文是学生在高中阶段第一次接触演讲辞，有必要让他们了解演讲辞的特点及课文如何体现这些特点的。随着年龄的增长，生活阅历的增加，高中学生正逐渐形成自己对世界、对人生的看法，蔡元培先生的这篇文章能很好地激发他们对当前的高中学习和未来的大学生活进行思考。此外，学生对北大的历史及蔡元培先生作这番演讲的时代背景了解不深，应作出补充说明。

一、说教材《十六年前的回忆》是统编语文小学六年级下册第四单元中的一篇精读课文。本课的作者是李星华，通过对李大钊被捕前到被捕后的回忆，展示了革命先烈忠于革命事业的伟大精神和面对敌人坚贞不屈的高贵品质，表达了作者对父亲的敬仰与深切的怀念。除开头外，文章是按被捕前、被捕时、法庭上、被害后的顺序来叙述的。被捕前写父亲烧掉文件和书籍，工友阎振三被抓，反映出形势的险恶与处境的危险；被捕时写了敌人的心虚、残暴与父亲的处变不惊；法庭上描写了李大钊的镇定、沉着；被害后写了全家的无比沉痛。 本文是回忆录。作者采用第一人称的叙述方式，回忆了父亲被害的全过程，内容真实可信，语言朴素自然，既具有文学价值，又具有很强的史料价值。选编这篇课文的主要意图，一是使学生借助课文，激发对革命先烈的崇敬之情；二是引导学生领悟课文前后照应的写法。

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。
