    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。

    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。

    Ⅲ. Analysis of the teaching material:The topic of this unit is cultural relics. Students are quite interested in topics about different cultures around the world. This is the second period of the whole unit. As a reading class, the passage mainly talks about the history of the amber room (how it was made, sent as a gift, lost and rebuilt).According to the new national curriculum, when teaching reading, much emphasis should be put on training the students’ reading skills.Ⅳ.

    Step 2 Pre-listeningAfter students finish their discussion, I will show a picture of Newton and ask them: Who is him? What is he famous for? Could you find out some words to describe him? Maybe students will answer that he is genius for his finding of theGravitation, making a great contribution to the progress of human being. At that time I will show another two pictures of Einstein and Hawking, letting students guess who they are and write down their idea about the Gravitation. For I have arranged them to search more information about the gravity before this class, Students have beenfamiliar with the topic and will not be afraid about this abstract conception, which is helpful for their listening.Step 3 While-listeningIn this step, students will be required to listen the material for three times. The first and listening is extensive listening and the second and third listening is intensive listening. In the first time, They are required to listen a material including Part 1 and Part 2 and choose the best summary of the listening text. After they choose the right answer, They also need work in group to explain what is wrong with the others. Then I will make a conclusion that we should pay attention to the first paragraph and last paragraph and some keys to get the main idea. By doing this, their capacity of generalization will have a great improvement.Before the second listening, I will ask students to scan the blank on the power point quickly and ask them to note down some key words .Then ask them to listen to the Part 1again and fill the first column of the chart. Maybe some students just show the ideas of these three scientists an still can’t catch their development of gravity. Therefore, I will ask them to listen to Part 2 again and fill in the rest. After finish the listening, I will give them ten minutes to discuss with their partner. I will also guidethem to improve their answers when they discuss with others.

    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

    XX中小学生安全教育日国旗下讲话稿:安全在我心中

    老师们、同学们:大家早上好!每年三月最后一周的星期一定为全国中小学生“安全教育日”。XX年安全教育日主题:强化安全意识,提升安全素养。今天我国旗下讲话的题目是《安全在我心中》。中外古今,多少文人墨客用优美的文笔唱出了对生命的歌颂。人们歌颂生命,是因为生命的宝贵,人们热爱生命,是因为生命的美好。然而,生命又是脆弱的。当生命遭到灾难或伤害时,它就会转眼消逝,那些鲜血写成的教训,使我们感悟到了生命的可贵,感悟到了安全的重要。据有关部门调查统计,全国每年约有1.6万名中小学生非正常死亡,平均每天有40多人。其中,交通事故已成为中小学生安全事故中的主要事故,食物中毒和意外伤害也一个个触目惊心、血泪交织的悲剧不能不叫人扼腕叹息、心有余悸,也更对我们敲响了安全的警钟。安全与我们每个师生密切相关,它关系到同学们是否健康成长,能否顺利完成学业。由于小学生年龄比较小,有时无法应对随时可能出现的各种危险,所以我们要加强教育,让学生远离危险,认识生活中的各种安全问题,学会正确处置意外,做好防范、树立起自我保护意识,提高自我保护的能力。

    (一)教学内容我说课的内容是人教版小学数学四年级第三单元第一小节“加法运算定律”中的第1课时的内容,其内容包括:第17页的例1以及18页的“做一做”第一题、第19页练习五第1~3题的部分习题。(二)教材地位数学中,研究数的运算,再给出运算的定义之后,最主要的基础工作就是研究该运算的性质。在运算的各种性质中,最基本的几条性质,通常称为“运算定律”。加法是数学中最基本的运算之一。通过本课时的学习,首先,可使学生对加法的认识从感性上升到理性。其次,用不完全归纳法概括出加法交换律的文字表述形式和字母形式,一方面提高知识的抽象概括程度,另一方面为以后正式讲用字母表示数打下初步基础。(三)教学目标1、通过学习,使学生理解和掌握加法交换律,并会运用加法交换律进行简便计算。2、让学生学会用符号或字母来表示加法交换律。3、培养学生抽象概括能力,引导学生由感性认识上升到一定的理性认识。

    小学数学人教版五年级下册《异分母分数加减法》说课稿

    重难点依据人教版数学教材新课程标准,在吃透教材的基础上,我确定了掌握异分母分数加减法的计算法则为教学重点,因为只有掌握了计算法则,才能进行计算。同时,也确定了理解异分母分数加减法计算时必须先通分的算理为教学难点。 二、说教法我们都知道数学是中国教育中一门必修学科,因此,从小学数学教学开始,就不仅要使学生“知其然”,还要使学生“知其所以然”。我们在以师生既为主体又为客体的原则下,展现获取理论知识、解决实际问题的思维过程。考虑到五年级学生的现状,我主要采取设置情景教学法,让学生积极主动地参与教学活动,使他们在活动中得到认识和体验,产生践行的愿望。当然老师自身也是非常重要的教学资源。教师本人应该通过课堂教学感染和激励学生,调动起学生参与的积极性,激发学生对解决实际问题的渴望,并且要培养学生理论联系实际的能力,从而达到最佳的教学效果。

    1、教材分析《同分母分数加减法》是人教版五年级下册第五单元的内容。本节教学内容包括分数加减法的含义、同分母分数加减法的计算方法和连加、连减三个部分。这部分内容是在学生学习整数、小数加减法的意义及其计算方法,分数的意义和性质,以及在三年级上册学过的简单的同分母分数加减法的基础上进行教学的。为异分母分数加减法的学习搭好阶梯。2、学情分析相对整数加减运算而言,分数的加减运算对于大多数学生来说是比较困难的,但是学生对简单的同分母分数加减法计算有一定基础。学生已有一定的生活经验,并有一定的分析和解决问题的能力,会有条理地表达自己的思考过程。3、教学目标(1)知识与技能:掌握同分母分数加减法的计算方法,理解相同单位的数相加减的算理及含义,并能够正确熟练地计算。(2)过程与方法:能够利用所学知识解决生活中的实际问题,培养学生应用知识的能力。(3)情感态度与价值观:通过小组合作学习,培养学生的合作意识和学好数学的信心。
