人教版高中生物必修2基因在染色体上说课稿
三、孟德尔遗传规律的现代解释①分离定律：在杂合体的细胞中，位于一对同源染色体上的等位基因，具有一定的独立性；在减数分裂形成配子的过程中，等位基因随同源染色体的分开而分离，独立地随配子遗传给后代。②自由组合定律：位于非同源染色体上的非等位基因的分离或组合是互不干扰的；在减数分裂过程中，同源染色体的等位基因彼此分离的同时，非同源染色体上的非等位基因自由组合。总结：再次强调孟德尔遗传定律的现代解释课堂练习：书本31页6、教学反思：本节课设置了一系列问题情境，层层设问，在学生答问、质疑、讨论过程中让学生建构新概念和新的知识体系，并通过教师及时掌握反馈信息，适时点拨、调节，让学生在推理判断中培养良好的思维习惯和对知识的迁移能力，而且通过留出一定的时间让学生提问，体现了以学生为主体的思想。
人教版高中生物必修2DNA的复制说课稿
设问：DNA复制后两个子代DNA分子与亲代DNA分子是否完全相同？为什么？通过设问，让学生进一步理解和巩固DNA复制的全过程。接下来让学生总结出DNA复制的四大基本条件：① 模板：开始解旋的DNA分子的两条单链；② 原料：是游离在核液中的脱氧核苷酸；③ 能量：是通过水解ATP提供；④ 酶：酶是指一个酶系统，不仅仅是指一种解旋酶。最后通过以上分析，总结出DNA复制的意义以及在生活中的应用：意义：DNA通过复制，使遗传信息从亲代传给子代，从而保证了物种的相对稳定性，保持了遗传信息的连续性，使物种得以延续。应用：目前DNA分子广泛应用于刑事案件侦破等方面：如：DNA分子是亲子鉴定的主要证据之一。把案犯在现场留下的毛发、血等进行分析作为破案的证据，与DNA有关。五、设计课堂练习：设计一题典型课堂练习：即有关半保留复制及计算的习题：

人教版高中生物必修2染色体变异说课稿
四、说教学程序（一）.温故知新、导入新课复习提问:基因突变导致生物变异的原因是什么?回答:基因突变是基因结构发生改变，从而使遗传信息改变，使蛋白质结构改变、生物性状改变，即生物发生了变异。那么，基因是什么?它和染色体又有何关系?回答:基因是有遗传效应的DNA片断，染色体是DNA的载体，基因在染色体上呈线形排列。引出新知:对于一个生物体来说，正常情况下，其染色体的结构和数量都是稳定的。但在自然条件或人为因素的影响下，染色体的结构和数量均会发生改变，从而导致生物性状的改变，这就属于染色体变异。（二）.把握重点、突破难点重点的把握：1、染色体结构的变异播放影片:猫叫综合征幼儿。让学生观察: 患儿哭声轻、音调高，很像猫叫。教师补充: 患儿的征状---两眼较低、耳位低下，存在着严重的智力障碍。阐述病因---染色体片段缺失

人教版高中政治必修3感受文化影响说课稿
（2）世界观，人生观，价值观是人们文化素养的核心和标志。一旦形成就会对人产生深远持久的影响。（但随着生活阅历的变化，人们文化素养的提高，人们的“三观”会发生变化。）总之“潜移默化”指每时每刻，不知不觉；是从文化对人影响的过程来看的。“深远持久”指经年累月，难以抹去；是从文化对人影响的结果上说的。3.课堂总结：首先启动学生思维，教会学生把握知识主线，建构知识体系，先由学生进行总结，然后教师进行必要的补充4、布置作业：布置作业。运用文化对人的影响的知识分析“近朱者赤，近墨者黑”，并且应该如何处理朋友之间的关系。设计这个作业的意图是既让学生灵活运用所学知识，同时又让学生回归生活，如何处理朋友之间的关系。5、板书设计遵循板书设计的实用性、直观性的原则，根据本课的教材特点，我采用结构式板书，这样设计比较直观、系统，以便于学生能够系统把握和理解知识。
人教版高中政治必修3聚焦文化竞争力说课稿
（1）文化与经济、政治在经济基础上相互影响。①经济、政治和文化是社会生活的三个基本领域。其中，经济是基础，政治是经济的集中表现，文化是经济和政治的反映。一定的文化由一定的经济、政治所决定，又反作用于一定的政治、经济，给予政治、经济以重大影响。②经济发展是文化发展的基础。但这并不意味着文化的发展始终与经济的发展亦步亦趋。如同不能简单地把精神文明看作是物质文明的派生物和附属品一样，也不能简单地认为文化是经济、政治的派生物和附属品。文化有其自身的传承性和相对的独立性。那种认为只要物质条件好了，精神文化自然而然地就会好起来，物质条件差一点，精神文化就不可能搞好的观点，不符合历史发展的事实，是不正确的。③掀开历史的画卷，文化既有古今和地域之别，又有先进与落后、腐朽之分。不同的文化，对经济、政治的影响不同，对社会发展的作用也不同。不同民族的文化，影响不同民族和国家各具特色的发展道路。

人教版高中政治必修3文化创新的途径说课稿
一、 教材分析1、地位和作用《文化创新的途径》是人教版教材高二政治必修3第二单元第五课第二个框题内容，本课是对全面两课的一个提升，同时对接下来学习第三、四单元的知识具有指导作用。文化创新是一个社会热点，具有很强的思想理论性和探索实践性。在前面两课中，学生基本明确了文化的交流、传播和发展；也明白了文化的继承和发展需要创新。而怎样进行创新是本节课探讨的内容，也是本单元的重点、难点和落脚点。2、教学目标（1）知识与能力目标：①识计文化创新的途径；理解文化创新过程中要认识和处理好两对基本关系：当代文化与传统文化、民族文化和外来文化的关系；②使学生初步具备认识和处理当代文化与传统文化、民族文化与外来文化关系的能力；使学生具备在合作、探究中体验生活、生成认识、构建知识的能力。
人教版高中政治必修3体味文化说课稿
3、文化的力量。为了使学生能辨证地分析文化的力量，我设计了两个问题进行探讨：（1）是不是任何文化都能起促进作用？（2）你在听或唱国歌时感受到一种什么样的力量？这样，学生在对比中学会辨证地分析文化的力量——先进的、健康的文化能促进社会发展和个人成长；落后的、腐朽的文化则阻碍社会发展和个人成长。同时还能提高学生的文化赏析能力，从而引导学生装自觉参加健康有益的文化活动，抵制不良文化的影响，投身到社会主义精神文明建设中去。关于课堂练习，我准备了5个针对性比较强的选择题，从而加深巩固本框题的重难点知识。最后，播放歌曲《走进新时代》，展示本课知识结构，指出本框题需重点掌握的问题，结束本课教学。课后作业，我设计了这样一个辨析的题目：文化是人们创造的全部财富的总和，它是人类特有的现象。
人教版高中政治必修4意识的本质说课稿
师：分析得非常到位。大家来看看薛宝钗是怎么说的？薛宝钗的评论：“不像吟月了，月字底下放一个‘色’字倒还使得，你看句句倒是月色。这也罢了，原来诗从胡说来，再迟几天就好了。”生：（读第三首诗）“精华欲掩料应难，影自娟娟魄自寒。一片砧敲千里白，半轮鸡唱五更残。绿蓑江上秋闻笛，红袖楼头夜倚栏。博得嫦娥应借问，缘何不使永团圆！”这首诗语言很朴实，但意境很深远。我虽然读过《红楼梦》这本书，也看过电视剧，但我阅历太浅，说不出诗中所包含的深刻内涵。师：贾宝玉的评论：“这首不但好，而且新巧有意趣，可知俗语说的‘天下无难事，只怕有心人。2．意识的形式是主观的意识是人脑对客观存在的反映，意识是不是仅仅是人脑对客观存在原原本本的反映呢？“龙、凤”是中华民族的象征，是炎黄子孙的两大主要图腾，但地球上从来就没有出现过“龙、凤”，那么“龙、凤”的观念又是从何而来的呢？原来，“龙、凤”的观念最早产生于原始社会的图腾崇拜。、
人教版高中政治必修4价值与价值观说课稿（二）
二、学生情况分析(说学法)1、学生学习基础分析：学生通过对《生活与哲学》前面三个单元的学习，初步掌握了运用唯物论、辩证法、认识论的观点去认识问题、分析问题的能力；再通过对第十一课的学习，学生对马克思主义的历史观有了初步的理解，初步树立了正确的理想信念，这为本课教学目标的落实奠定了知识基础。 2、学生能力分析 ：高二学生拥有一定生活体验，具备一定的信息收集和筛选能力、阅读能力、语言表达能力、对问题的一定的探究能力，同伴合作能力和具备初步逻辑思维能力。3、学生心理分析：在我国现阶段，以为人民服务为核心的社会主义道德建设过程中涌现了大批的先进人物和道德典范，但同时由于社会价值的多元化，个人主义、享乐主义、拜金主义等资本主义腐朽思想也同样在影响着当代的中学生。

人教版高中英语必修4A taste of English Humor说课稿3篇
Then I would ask them to think of a funny English or Chinese and tell it to partners. While telling stories, they can use expressions and some acting to help make the story funny. 5 minutes would be given to do this.Those stories they told there will be the material for their writing. Soletting them tell it at first is helpful. And they can make a difference between telling a funny story and writing it down. Generally speaking, it is difficult forstudents to write well because they don’t know what to write and how to write. Asking them to tell their own stories at first can help them come up with what to write.After their telling, I would invite someone to share his/her story with all of us and I would write it down on the blackboard.This example story would be used as a sample to illustrate the format of funny story. Different from a story from teacher or textbook, a story from students can obviously become a interesting material to draw students’ attention.Then I would ask the whole class to put this story into several parts. It might be a little bit difficult for them. So I would ask them to find out whether all the sentences are necessary. After delete some sentences, there are 6 sentences left behind. Then they can easily put them into three parts. After interaction with students, I would teach them the right terms for each part and conclude the format of funny story.This step is the key and difficult point in my lesson. So I mainly usetask-based teaching method in this part and the task for students was divided into several stages. With the separated difficult level, students can find there are usually three parts in writing. They can also learn to write without the unnecessary parts in the process of analyzing. And then I wouldn’t rush to tell them the right terms to them directly. Instead, I would ask them to name them by their own. A confused mind is better for acquiring knowledge.While-writing:Then I would give students 7 minutes to write down this story, without other requirements.With all the preparations in pre-writing, students’ difficulties were cleared. So it would be much easier for them to write down the story within 7 minutes. There are no other requirements because students’ first writing is actually a drafting. It would be revise and edit several times later. Writing, as a skill

My students are in senior high students. They have learnt English for many years, they’ve known many words and sentences, but their speaking and reading abilities are still not very good. So I will practice their speaking and reading abilities through different exercises.According to the New Standard Curriculum and the present situation, I set the teaching aims as follows: firstly, knowledge aims. Students can grasp some new words, such as worthwhile, move off. Moreover, students can understand the content of the passage and get familiar with the topic of studying chimps in wildlife. Secondly, ability aims. Students can use reading strategies such as skimming and scanning in reading process. Thirdly, emotional aims. Students can have the awareness of protecting animals and care about animals.Based on the above analysis, the key point of this lesson is to get the main idea and the detailed information from the passage; the difficult point is to talk about the wildlife protection and use reading strategies.
