人教版高中政治必修1股票与债券说课稿
一、说教材（一）说教材的地位和作用《股票、债券、保险》是人教版必修1《经济生活》第六课，第二框题的内容。本框题承接前面“企业与劳动者”：企业的发展资金从何而来，同时又为下一课“个人收入与分配”做好了铺垫，它在整个教材中起承上启下的作用。因此，本框题在《经济生活》中具有不容忽视的重要的地位。（二）说教学目标根据高一新课程标准要求，本教材的结构和内容分析，结合着高一年级学生的认知结构及其心理特征，我制定了以下的教学目标：1、知识目标（1）股票的含义、收益、特点和发展股票市场的意义。（2）债券的含义与分类（3）商业保险的含义与订立原则2、能力目标（1）重点培养学生辩证思维的能力，发现和分析、解决问题的能力。3、情感、态度与价值观目标培养科学理财的意识，形成“投资理财，利国利己”的观念。（三）说教学的重、难点本着高一新课程标准，在吃透教材基础上，我确定了以下的教学重点和难点
人教版高中政治必修1信用工具和外汇说课稿
一、对教材内容的处理根据新课程标准的要求、知识的跨度、学生的认知水平，我对教材内容有增有减。二、教学策略的选用（一）运用了模拟活动，强化学生的生活体验,本框题知识所对应的经济现象，学生已具有了一定的生活体验，但是缺乏对这种体验的深入思考。因此在进一步强化这种体验的过程中进行了思考和认知，使知识从学生的生活体验中来，从学生的思考探究中来，有助于提高学生的兴趣，有助于充分调动学生现有的知识，培养学生的各种能力，也有助于实现理论知识与实际生活的交融。（二）组织学生探究知识并形成新的知识我从学生的生活体验入手，运用案例等形式创设情境呈现问题，使学生在自主探索、合作交流的过程中，发现问题、分析问题、解决问题，在问题的分析与解决中主动构建知识。也正是由于这些认识来自于学生自身的体验，因此学生不仅“懂”了，而且“信”了。从内心上认同这些观点，进而能够主动地内化为自己的情感、态度、价值观，并融入到实践活动中去，有助于实现知、行、信的统一。
人教版高中政治必修1税收及其种类说课稿
在学生明确了税收的含义之后，我将分别对税收的三个基本特征进行解析。在讲解了之后，并分别用实例对其进行说明，加深学生对知识点的印象。最重要的是，总结出关键的字眼，使得学生能够清晰的区分出税收的三个基本特征。将强制性概括为依法征税、依法纳税；无偿性概括为不具有偿还性和返还型；固定性概括为规定应不应纳税、纳什么税、纳多少税。并跟学生指出，强制性是基本前提，无偿性是核心。由此根据书上的内容，推导出税收的三个基本特征相互之间的关系，即：三者缺一不可，统一于税法。而且，无偿性要求强制性，强制性保障无偿性；而无偿性与强制性又共同决定固定性。从而结束新课讲授。3、课堂总结根据板书内容重新回顾本课学习的主要内容，包括税收的含义，以及税收的三个基本特征和它们之间的相互关系。4、作业布置让学生预习税收的种类的内容，尤其是增值税和个人所得税。同时了解父母每月所缴纳的个人所得税和怎么计算的。

人教版高中政治必修3建设学习型社会说课稿
解析：材料是讲学习型社会所产生的影响，A项观点错误，在当前和今后相当长的时间里，学校教育仍然是人们获得知识的最重要的途径。B项观点错误，终身学习只是成就人生目的的手段、途径，而不是目的本身。D项说法错误，当前我国社会的中心工作是经济建设。二、问答题5.材料一：日本是公认的漫画大国，日本的动漫产业产值每年230万亿日元，成为日本的第二大支柱产业。在日本，漫画比电影、小说有时甚至比电视或音乐更受欢迎。日本漫画的热潮还席卷了世界：日本每年出口到美国的卡通片价值就达5 000亿日元，是日本对美国钢铁出口金额的4倍；漫画中的人物被迅速复制成电子游戏、卡通片及真人演出的节目。原来只是闲暇时候消遣的漫画，正飞速渗透到人们的生活中。值得警惕的是，除了催人奋进的精华之外，日本漫画中也存在暴力、色情、扭曲历史等诸多糟粕，对缺乏辨别能力的青少年产生了许多不良影响，更引发了一系列深刻的社会问题。
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。

在接下来的细读环节，我套用了高考对阅读理解的考查方式设置了5个问题，分别为三个推理判断题，一个细节题和一个主旨大意题。学生需要对文章的内容进行分析、归纳、推理、猜测等高级思维活动才能做出正确的回答。【设计意图】这一过程是对学生进行细读的训练，培养学生获取特定信息和挖掘文章深层次信息的能力。第三环节:Intensive-reading (精读) 15′第三个环节精读，既是最重要的环节，也是突破本课重难点的关键。首先，让学生思考剧本中人物看到百万英镑前后的态度发生了怎样的变化。其次，让学生仔细阅读文章，找出可以表现人物态度变化的具体的语言和动作。最后，让学生总结人物的态度发生变化的根本原因是什么，从而引出Money Talks, 供学生思考。【设计意图】通过一系列的活动培养学生学习从人物的语言和动作探究人物的心理，使学生进一步体会戏剧语言的魅力，从而对文章背后所反映的社会问题进行思考，也为下一步的讨论环节做好铺垫。
