《奇偶性》内容选自人教版A版第一册第三章第三节第二课时;函数奇偶性是研究函数的一个重要策略,因此奇偶性成为函数的重要性质之一,它的研究也为今后指对函数、幂函数、三角函数的性质等后续内容的深入起着铺垫的作用.课程目标1、理解函数的奇偶性及其几何意义;2、学会运用函数图象理解和研究函数的性质;3、学会判断函数的奇偶性.数学学科素养1.数学抽象:用数学语言表示函数奇偶性;2.逻辑推理:证明函数奇偶性;3.数学运算:运用函数奇偶性求参数;4.数据分析:利用图像求奇偶函数;5.数学建模:在具体问题情境中,运用数形结合思想,利用奇偶性解决实际问题。重点:函数奇偶性概念的形成和函数奇偶性的判断;难点:函数奇偶性概念的探究与理解.教学方法:以学生为主体,采用诱思探究式教学,精讲多练。

(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。

2、传授新知与学生展示(35分钟) 先由老师点出本课的知识点,它包括:(1)经济全球化深入发展:结合课本91-93页理解经济全球化的含义;经济全球化的表现:生产全球化,贸易全球化,资本全球化;跨国公司是实现经济全球化的载体。(跨国公司的含义、目的、作用分别是什么)(2)经济全球化的影响: 经济全球化的实质:以发达资本主义国家为主导的经济全球化;消极影响积极影响;如何应对经济全球化。讲完了知识点,接着回归图片和书本的材料,给学生留下三个问题进行小组讨论:A :谈谈你感受到的经济全球化B :怎样理解经济全球化是一把“双刃剑”C:假如你是一位企业经营者,面对经济全球化趋势,你会怎么做?先完成讨论的小组可举手示意老师给予检查,老师根据需要抽查同学到讲台进行展示讨论的结果,并对表现突出的小组进行当堂奖励。

(二)讲授新课:1、讲授重点:文化与经济、政治的关系。我首先带领学生分析课本上的活动探究,了解日常生活中的常见活动,让学生们观看视频材料帮助学生对文化活动、经济活动、政治活动进行辨别和分类。然后让学生们举例说明,综合探究,最后通过集体讨论得出文化与经济政治的关系: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和政治决定,又反作用于政治和经济。这个问题是本课重点。要引导学生循序渐进,集体讨论,得出结论。2、突破难点:(1)文化与经济政治相互交融,在时代发展的进程中。首先播放上海世博会视频,让学生体会文化、经济、政治活动,另外我会引导学生积极举生活中的事例,来说明问题,让学生学会举一反三,充分理解这一知识,让学生明白文化与经济、政治的联系,让学生清楚文化渗透的力量有多大,帮助学生树立反对文化霸权主义的意识。

f.有丝分裂的意义(讨论分析教学),首先引导学生结合所学知识讨论有丝分裂的的作用,最后有教师归纳总结,并要求学生在理解的基础上记忆。g.无丝分裂(图形直观教学、简介),本部分内容不是教学的重点,内容也相对简单,所以我的教学方法是直接给学生展示挂图,再进行简短介绍,让学生了解即可。h.引出减数分裂的概念,为第五章学习打下基础。小结:新课讲完以后由教师对本节内容进行总结巩固和反馈:进行一些课堂练习达到巩固和反馈的作用。最后布置作业,各种难度的作业题目均设置一些,其中简单题比重大,难题要求学生选作,这样提高学生学习积极性。2教学媒体程序设计: 细胞周期的概念(多媒体课件演示周期动画)植物细胞有丝分裂(多媒体课件演示分裂各期动画)动植物细胞有丝分裂异同点(多媒体课件演示分裂各期动画)有丝分裂过程中DNA和染色体数量的变化规律(挂图演示,包括表格和函数图象)

在讲述细胞分化的意义时,也可以用实例来解决,工厂的生产车间里不同的工人干着不同的工作,一件产品的产出需要这些工人才能创造出来,一个生物体就像一个车间一样,不同的细胞各司其职,相互合作。工人的分工是主管调解出来的,而不同细胞的出现就是细胞分化的结果,所以说,细胞的分化是生物体发育的基础。在讲到细胞全能性的时候,要多给学生举些关于细胞全能性的例子,如植物组织培养、克隆技术等等,让学生从实际的例子中真正的悟出细胞全能性的含义。此外,还要重视教材中的疑问,适当对题目进行引申,使它的作用更加突出,有利于学生对知识的串联、积累、加工,从而达到举一反三的效果。怎样来解释细胞的全能性呢?这主要以讲授法来解释了,细胞全能性的体现需要在组织或器官离体后才能体现出来,每个细胞都包含着生物体的全套遗传基因,通过基因选择性的表达,使离体的组织或器官通过分裂和分化逐渐发育成完整的植株。

本板块的活动主题是“谈论节日活动”(Talk about festival activities),主要是从贴近学生日常生活的角度来切入“节日”主题。学生会听到发生在三个国家不同节日场景下的简短对话,对话中的人们正在参与或将要亲历不同的庆祝活动。随着全球化的进程加速,国际交流日益频繁,无论是国人走出国门还是外国友人访问中国,都已成为司空见惯的事情。因此,该板块所选取的三个典型节日场景都是属于跨文化交际语境,不仅每组对话中的人物来自不同的文化背景,对话者的身份和关系也不尽相同。1. Master the new words related to holiday: the lantern, Carnival, costume, dress(sb)up, march, congratulation, congratulate, riddle, ceremony, samba, make - up, after all. 2.

Inspire students to use topic words to describe the festival activities based on their background knowledge. Difficulties:In the process of listening to the correct understanding of the speaker's attitude, accurately identify the relationship between the characters.

一.教材理解教材地位与作用:本单元“阅读与鉴赏”部分,本单元要求学生能在了解诗歌创作的时代背景的情况下通过反复诵读诗歌,把握其中丰富的意象,领悟诗歌独特的意境和诗人所要表达的情感。《雨巷》是现代派大师戴望舒的成名作和前期的代表作,他曾因此而赢得了“雨巷诗人”的雅号。本单元以《雨巷》为例子给学生展示了象征主义诗歌的特点,《雨巷》运用了象征性的抒情手法。诗中那狭窄阴沉的雨巷,在雨巷中徘徊的独行者,以及那个像丁香一样结着愁怨的姑娘,都是象征性的意象。这些意象又共同构成了一种象征性的意境,含蓄地暗示出作者即迷惘感伤又有期待的情怀,并给人一种朦胧而又幽深的美感。富于音乐性是《雨巷》的另一个突出的艺术特色。诗中运用了复沓、叠句、重唱等手法,造成了回环往复的旋律和宛转悦耳的乐感。因此我把本课的教学重点和难点确定为:教学重点:通过反复诵读,领略诗歌的音乐美以及分析其成因教学难点:分析意象以及其象征意义初步掌握鉴赏诗歌的方法

Good morning, distinguished judges:It’s my honor to talk about my teaching ideas with you. Today my topic is Women of Achievement. My presentation consists of six parts: the analysis of teaching material and student, teaching aims, key and difficult points, teaching and studying method, teaching procedures and blackboard design.First, let’s focus on the analysis of teaching material. This lesson is from New Senior English for China Student’s Book 4 Unit 1, the reading part. The main topic of the passage is the introduction of a student of Africanwildlife. After this lesson, the students will learn more information about her studying chimps in Africa, and their reading and speaking abilities can be developed as well.The next part is the analysis of students. 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.

1.说教材《记念刘和珍君》是鲁迅先生用饱醮着热泪,用悲愤的笔调写下的一篇感人至深的散文,既有对爱国青年沉痛的悼念,又有对反动派愤怒的控诉,也有对觉醒的国民的呐喊。《记念刘和珍君》是高中语文必修1第三单元第一课的讲读课文。文中描摹人物的音容笑貌,叙述人物的行为事迹,都融入了作者真挚的情感和深刻的感悟。对学生明辨是非,领悟时代精神和人生意义,有着重要的作用。新课标强调了要全面提升高中学生的语文素养,初步形成正确的世界观、人生观、价值观,并学会收集、判断、处理信息,具有人文素养、创新精神与实践能力。同时,《记念刘和珍君》感情真挚,感悟深刻,具有典型人文性。结合本单元教学目标,确立教学目标如下。

4、学习全词:(1)背景介绍,让学生看课文中的年代,然后让学生回忆1925年的毛泽东的情况,老师适当提示,让学生了解其背景。(出示幻灯片)(2)学生自由朗读,结合注释和背景理解诗词。(3)师生共同理解全词①先让学生齐读前三句,思考正确的语序,并用正常的语序解释。②品味第三到第十句,这里是教学的一个重点,要让学生先读,再理解,在此基础上训练学生的想象能力。③分析上阙中的最后三句。④小结上阙。提出了一个问题“谁主沉浮”让学生在文中找内容回答,然后转入下阙内容的分析。⑤分析下阙内容,回答“谁主沉浮”的问题,突出本文主旨5、描绘诗词形象:学生用自己的语言把上阙的内容生动地描绘出来。6、欣赏学生优秀作品。(根据时间具体而定,也可以作为课后作业)

3、拓展延伸,启迪心智,创设课堂训练营。三、说学法1、纸上得来终觉浅,圈点、勾画、批注法,学好文言基本功。2、自主合作加探究,眼耳口脑手并用,破疑解难在其中。四、说课时安排《鸿门宴》篇幅较长,文言知识较丰富,文章内涵丰厚,因此我设计用五课时教学本文。第一课时:了解作家作品,积累文言知识,感受作者隐忍发愤的著书精神(初读)第二课时:理清故事情节,概括人物形象,学习客观地评论历史人物,(熟读)第三课时:进一步梳理文言知识,精读课文,要求读透。(精读)第四课时:通过对人物、事件的赏析,加深学生对人物的理解,锻炼学生的开放性思维,由学生自主认识到人物的性格,悲剧的原因等问题。(赏读)第五课时:补充课本教学内容:同学生一起阅读古今关于刘邦项羽的一些篇章:让学生投入进来,把握自己眼中的项羽。(展读)在文言文学习的过程中,采取五步学习法:初读-熟读-精读-赏读-展读(板书)

【教学目标】我设置的本课的教学目标有三个:1、知识与技能(1)了解曹雪芹及《红楼梦》(2)学习通过一个人物的行踪、所见所闻,介绍典型环境,认识封建贵族阶级豪奢极耻的生活以及森严的等级、礼仪制度(3)分析小说人物出场的描写艺术,培养学生分析小说人物形象的能力。(4)一叶落而知秋”,通过对“林黛玉进贾府”这一故事情节的把握是否能引发对《红楼梦》的认知兴趣,并找到一个突破口,有针对性地进行自主探究,进而进行个性化解读。(5)整体认知小说,认识小说悲剧的必然性和思想价值.2、过程与方法(1)用直观演示和归纳探究法分析文章要点。(2)用讨论探究法体验作者对文中人物的情感态度。3、情感态度价值观(1)正确理解《红楼梦》的思想内涵,培养学生热爱祖国传统文化的思想感情。(2)认识封建大家族的腐朽没落,理解贾宝玉追求个性自由反封建的精神。

本文篇幅较长,并且有一字句不易理解,因而对高一学生来说完全读懂内容有一些困难。这样的话,老师就要做好引导工作,把一些难点,或是出现词类活用比较多,局势比较特殊的句子,老师可以先给学生画出来,存疑,或是与同学们一起讨论解决。对那些不易懂的字词就引导学生联系上下文提供的语境、前后涉及的情节加以推测、判断,以培养学生依据文脉推断词义的好方法。要求学生点出重点实词、框出通假字,主要是为帮助学生积累和掌握一些文言文中常见的一词多义、异读现象、古今异义和通假现象的词语,并进一步得出规律,指导今后的文言文学习。词类活用和特殊句式在文言文翻译中难度较大,也是本文教学的两大难点。要求学生标出有活用现象的字和划出句式特殊的句子,是基于两点考虑:1、积累一定数量的第一手例句;2、引导学生加以分类,找出每类的相同特征,并抽取出来形成规律性的东西,从而上升到理性认识,使学生能由学会一个到会学多个。翻译过程中注重指导学生养成用符号法表示重点字句的好习惯,如点、框、圈、划线等符号应约定一致,便于突出翻译中的重点、难点及复习。我的提示着重归纳了实词“制”“亡”“遗”“利”等,名词活用、形容词活用、使动用法,被动句、状语后置句。
