二、说教法与学法学生的经验和活动是他们学习数学的基础。本节课的教学本人根据数学新课标的基本理念,精心设计学生的数学活动,充分利用了多媒体教学手段,调动学生多种感官参与学习。让学生在实际中运用所学知识,体现了数学来源于生活,生活离不开数学。整节课以游戏、活动为主线,把教学内容清晰有趣地串了起来,设计了新颖的情景教学和动画故事,尽可能的激发学生的求知欲望。教学过程紧扣教材,层层递进,环环相扣,教师能根据学生的实际适时的引导,使整节课能顺利完成教学任务。有效的学习就是激励学生动手实践、自主探索与合作交流。本课教学中,本人就注意实践操作与游戏活动有机地结合,让学生在玩、交流中思考,在思考中探索,获取新知。三、说教学过程本节课的教学我主要设计了六个环节:提问导入、猜数游戏、实际应用、回顾总结、课堂作业。
一、说教材:“跷跷板”一课是一年级上册第二单元的内容,是在学生学习了比较多少和高矮、长短的基础上进行的体验活动。内容选取学生身边的、常见的、较感兴趣的事物,符合学生的年龄特点与生活经验。本节课的教学让学生通过实践活动,逐步加深对轻重的体验与理解,初步体会借助工具确定轻重的必要性。根据一年级学生的年龄特点和教材的设计意图,教学中应注意创设有趣的情境,使学生产生学习比较轻重的兴趣,让学生在具体的操作活动中独立思考、合作交流,发现比较的方法,使他们获得良好的情感体验,树立学好数学的信心,培养创新意识。二、说教学目标:1、通过比较的活动,让学生感受数学与生活的联系,培养学生仔细观察、认真思考的良好习惯。2、经历比较活动,增强轻重的生活体验。3、通过说一说、掂一掂、称一称的活动,使学生逐步加深对轻重的体验与理解,学会一些比较的方法,体会轻重的相对性。4、通过简单的推理活动,培养学生初步的推理能力。
二、说教学目标1.认识“渡、荫”等9个生字,会写“伞、姨”等8个生字。 2.默读课文,根据情境展开合理想象,并把想象的内容写下来。? 3.正确流利地朗读课文,有感情地朗读重点句子,感受作者对喜鹊的喜爱之情。三、说教学重难点1.识记生字,朗读课文,根据情境展开合理想象,并把想象的内容写下来。(重点) 2.感受“我”对枫树和喜鹊的喜爱,感受故事的童趣。(难点)四、说教法和学法1.创设情境法主要是通过创设情境,让学生进入情境中,激发学生的内在情感,为学生进行想象找到共鸣点和切入点。? 2.阅读法我采用朗读、默读。教师范读,表演读,分角色读等引导学生感受作者对喜鹊的喜爱之情。3.练习设计法《语文课程标准》中指出'语文课程是一门学习语言文字运用的综合性、实践性课程',充分说明了语文练习的重要性。练习有助于学生形成熟练的技能和发展学生的思维能力。因此,设计语言训练的练习,是在培养学生的应用意识、实践能力。新课程标准倡导'自主、合作、探究'的学习方式,于是我将'学习的主动权还给学生'。通过自主朗读、小组合作交流、讨论探究等方式开展。
一、说教材《沙滩上的童话》是统编语文小学二年级下册第四单元的一篇课文。这是一个非常感人的故事,课文比较具有童趣,与孩子的生活相贴近,符合孩子的年龄特点。 作者用诗一般的语言讲述了一群孩子在沙滩上垒起一座城堡,然后展开想象的翅膀编织了一个美丽的童话:城堡里住着一个凶恶的魔王,抢走了美丽的公主……最后,这群孩子成为攻打城堡的勇士,他们炸死了魔王,救出了公主。故事一方面展现了孩子们快乐缤纷的童年生活,另一方面也歌颂了一种人间的善良温情与正义。在孩子们的童话中,那对生活的热爱之情,那纯真地对他人的关爱和帮助,尽显人性之美。二、说学情二年级下学期,学生已经具备了一定的学习字词的能力和自主阅读的能力。这篇课文的词语比较浅显,可以让学生在阅读中自己积累。对于生字的教学,我重点讲述容易混淆的生字,同时,这样也可以从现在开始培养学生养成良好的预习及阅读习惯。 但学生由于年龄小,注意力不够集中,所以更喜欢情节性较强的故事,需要教师引导在故事中体验情感。
材料四:印度提倡“只生一个好”——鼓励三人小家庭 生男生女都一样材料五:印度尼西亚《人口发展与幸福家庭法》材料六:我国基本国策 计划生育(小结)通过对以上材料的分析我们可以得出这样的结论,不同的国家应该采取不同的人口政策,对与发达国家来说人口增长缓慢,应采取鼓励生育,吸引移民的措施;发展中国家人口增长较快,实行控制人口的政策已经迫在眉睫。不论是发达国家还是发展中国家共同的目标就是实现环境人口和社会经济的协调发展。【课堂小结】这节课我们主要学习了人口的自然增长,影响人口自然增长的因素有哪些?(人口的自然增长率和人口的基数)世界人口的数量在不同的历史时期表现出不同的特征,同一历史时期的不同地区,人口数量的增长又有不同的特点。面对不同的人口形势,各国应采取不同的人口政策。
《0的认识和有关0的加减法》是《数学(人教版义务教育课程标准实验教科书)》一年级上册第29页的教学内容。数字0在生活中应用广泛,不同的应用体现出0的不同含义,有关0的加减法也具有其独特的规律和特点。本节课教学目标有下:1.通过游戏、活动,使学生理解0的含义,会读、会写数字0,了解数的顺序。2.使学生在情境体验中理解有关0的加、减法的含义,并能熟练计算。3.通过在数学活动中的观察、思考、讨论、探索,提高学生自主学习的意识和发现简单规律的能力。4.培养学生的想像力、语言表达能力和初步的推理应用能力。教学实录与评析:一、活动中认识0──关于0的含义和书写1.排排队──复习数的顺序。师:这节课,数字王国有几位小客人要到咱们教室找朋友。他们来了。(敲门声)
1.初步探究,找切入点:我抛出问题:周恩来为什么会立下“为中华之崛起而读书”这一志向?文中的哪个词最能体现?这个词在文中出现几次?通过多个问题的设置,培养学生的理解能力,学生通过自己读课文,很快就能找出本文的关键词“中华不振”,在文中出现2次,进而引导学生划出句子。 2.比较阅读,交流发现:让生反复阅读两个句子,比较两处出现的“中华不振”有什么不同,然后在班上交流自己的发现,通过仔细比较阅读会发现:第一次的“中华不振”是由伯父告诉周恩来的,第二次的“中华不振”是由周恩来自己亲身体会到的。这一环节的设置,进一步激发学生的探索意识,让学生学会在阅读中进行比较分析,进一步的理解内容,体验情感。3.默读课文,交流感受:新课程标准指出:要让三四年级学生学会默读,做到不出声,不指读。通过让生默读课文,边读边感受:文中的哪些句子能让你感受到“中华不振”?划出相关句子,然后在班上交流感受,通过交流,有的同学会说:我从伯父的话语中能感受,有的会说:从妇女的哭诉中感受【这一环节的设置,通过让生读课文,找句子,谈感受,加深对“中华不振”的理解,更深入的体会当时周恩来的心情,理解周恩来立下志向的原因。
一、说教材本文写于“百日维新”失败的1900年。文章从日本人和西欧人称我国为“老大帝国”说起,以人喻国,怒斥当权的清王朝封建贵族官僚都是保守守旧、愚顽苟且的“老朽”,号召“中国少年”应肩负起救国的责任,为创造一个繁荣富强的“少年中国”而努力奋斗。表达了要求祖国繁荣富强的愿望和积极进取的精神。二、说学情三、说教学目标
在这段教学中可以插入世界主要铁矿、煤矿,以及我国主要的矿产基地、钢铁生产基地的相关内容,不失为区域地理知识的很好补充和巩固。那么从现状来看我国的钢铁产业基地多数污染较为严重,可见工业区位的选择同样要顾及到环境的因素,由此引入下一部分的内容。除了传统意义上的工业区位因素外,环境、政策以及决策者的理念和心理等日益受到人们的关注。在这段文字的处理上,只需进行概念、道理上的陈述即可,重点要放在污染工业在城市中的布局这一知识点上。首先要了解什么工业会造成怎样的污染,然后根据污染的类别分别讲解不同的应对方略,最后将配以适当的例题以期提高学生的整体把握程度和综合运用能力。最后将对本节内容进行小结,要在小结中阐述清楚本节课的两大内容:即工业的区位因素和工业区位的选择。然后点明本节课的主要知识点、难点、重点。在时间允许的情况下可以适当安排几道有关主导产业和城市工业布局的例题加以练习。
教材分析改革开放后我国的综合国力不断增强,人民对祖国统一的愿望越来越迫切。本节课以“一国两制”构想的提出,香港、澳门的回归和海峡两岸关系的发展为中心,说明实现祖国统一,完成中华民族复兴是历史发展的必然。第一目“‘一国两制’构想的提出”主要讲述了“一国两制”的含义及历史意义。第二目“香港、澳门的回归”着重讲述了香港回归、澳门回归的经过及历史意义,这是“一国两制”成功的实践。第三目“海峡两岸关系的发展”讲述了大陆注重发展与台湾的关系,促进海峡两岸的经济文化交流与合作,打破了几十年来海峡两岸的隔绝状态,促进了祖国统一的进程。此外,教材还通过“资料回放”“历史纵横”“学思之窗”等栏目,为学生学习提供了一些详细的史料。在教学中要分析图表资料,引导学生理解完成祖国统一大业,实现中华民族的复兴,是任何人也阻挡不了的历史潮流。
【课堂小结】本课主要讲述俄国十月革命后进行经济建设,并在建设中进行社会主义探索,期间先后出现了战时共产主义政策、新经济政策和斯大林模式,这些政策和体制的产生都是历史和当时现实有关,但也反映出在建设社会主义中既有成功的也由重大失误,主要在于缺乏现成的政策和模式可供借鉴,更在于理论上的缺乏。斯大林模式的形成同苏联当时社会生产力的发展水平相适应,它在初期和战争时期曾发挥了巨大作用,使苏联成为强大的社会主义国家。它建立的高度集中的计划经济体制和新型的工业化模式是苏联进行社会主义建设中的探索和创新,对二战后社会主义国家产生了深刻影响,促进这些国家国民经济的恢复和发展,形成了足以同资本主义相抗衡的社会主义阵营。但是,它没有解决社会主义民主政治建设和经济运行的一系列根本问题,违背了列宁关于把文化经济建设当作工作重心的指示,仍把政治斗争放在第一位。
(四)、活动交流,体验科学通过资料分析讨论以下三个问题:1、你知道爱滋病的传播途径吗?2、如何预防爱滋病?3、我们应如何对待爱滋病患者?面对艾滋病我们能做些什么?从而进入情感态度的教育。除此之外,我还设计一个开放性的作业“向全社会为关注艾滋病设计一个宣传广告”(形式不限,漫画、板书、倡议书等),让学生把爱心付诸于实际行动。在此基础上引出“免疫学的应用”从免疫预防、免疫治疗、器官移植三个方面讲述,让学生充分体验到知识和社会生活的紧密联系,让他们不在感到科学是那么的遥远,而是可爱的有用的。通过交流,让同学们体会到合作的魅力和重要性,进一步培养合作意识和合作能力。最后我设计一个资料搜集,让同学们选一个感兴趣的主题利用电脑在网上搜集有关资料。主题:1、你知道世界艾滋病日吗?历年的主题是什么?开展世界艾滋病运动有什么意义?
1、汉武帝尊儒的措施:(1)政治方面:起用很多儒学家参与国家大政。他规定,地方定期选出孝子、廉吏当中央任官,甚至还擢升平民、儒士为相。这明显扩大了官员的队伍,提高了官员的文化素质,巩固了封建统治基础,成为汉武帝文治武功的重要组成部分。也给后世封建王朝在用人方式方法上面提供了宝贵的借鉴和启迪。(2)思想方面:采纳董仲舒的建议,“罢黜百家 独尊儒术”(3)教育方面:儒家经典“五经”为国家规定的教科书。兴办太学和设立地方学校进行儒学教育。公元前136年,汉武帝正式规定《诗》、《书》、《礼》、《易》、《春秋》为“五经”;前124年,又在长安兴办太学,规定太学生员为博士弟子,一律由儒家五经博士负责教授,学完经考试合格后即可到政府任官。这是封建国家利用政权的力量兴办教育、提倡儒学,其必然对整个社会的教育事业有一定的导向作用。
二、应用生长调节剂的注意事项1、效果不稳定。2、使用时期。3、使用浓度和方法。4、使用生长调节剂仅是葡萄栽培管理的辅助手段,不能盲目孤立地依赖生长调节剂。生2:我们小组查的资料是关于小麦使用生长调节剂。小麦应用植物生长调节剂,可以调节植株的生长发育,具有控旺促壮、增强抗逆性、增加粒重、提高产量并有利于优质、早熟等多重效果。生3:我找了一篇生长调节剂对矮牵牛大型穴盘生产。师:上面三位同学利用课下的时间,在网上查的三段文字都相当的不错,大家可以从中学到一些书本上没有的知识,请大家结合刚刚三位同学的三段文字以及自己平时所积累的知识,讨论以下几个问题。师:你知道哪些农产品在生产过程中使用了植物生长调节剂?师:哪些水果在上市前有可能使用了乙烯利?师:生产过程中施用植物生长调节剂,会不会影响农产品的品质?师:如果你是水果销售员,面对半青不熟的水果,你认为应当使用乙烯利催熟吗?作为一个消费者,你又怎么看?
This teaching period mainly deals with grammar “restrictive relative clauses.” To begin with, teachers should lead students to revise what they have learned about the relative pronouns and relative adverbs. And then, teachers move on to stress more special cases concerning this grammar, such as the “preposition+ relative pronouns which and whom” and cases where we can omit the relative pronouns. This period carries considerable significance to the cultivation of students’ writing competence and lays a solid foundation for the basic appreciation of language beauty. The teacher is expected to enable students to master this period thoroughly and consolidate the knowledge by doing some exercises. 1. Guide students to review the basic usages of relative pronouns and adverbs of attributive clauses.2. Lead students to learn to use some special cases concerning restrictive relative clauses flexibly.2. Enable students to use the basic phrases structures flexibly.3. Strengthen students’ great interest in grammar learning.1. Help students to appreciate the function of relative pronouns and adverbs of attributive clauses in a sentence2. Instruct students to write essays using the proper relative pronouns and adverbs of attributive clauses.本节语法思考:定语从句在复合句中的作用是什么? 关系词有哪些?定语从句在复合句中的作用相当于形容词,它在句中作定语修饰名词或代词。他们在先行词和定语从句之间起到联系作用,同时在意义上代表先行词并在定语从句中担任一个成分。被定语从句所修饰的词称先行词,定语从句一般放在先行词的后面。
The theme of the reading and thinking is about “Understanding how a problem was solved”.The Listening & Speaking & Talking is about international co-work to protect the Mount Tai, in which the students from seven countries came up with many solutions even create the Mount Tai App. This section aims at showing how to solve a difficult and even tough problem about protecting the cultural heritage by the international co-work. So in this section, cultivating students’ international awareness is very clear and important. Concretely, with the economic development, how to balance the protection of cultural relics and social development is a big challenge for human. In the 1950s, the Egyptian government wanted to build the Aswan Dam across the Nile to control floods, produce electricity and water farms. But the proposal led to protests because it would destroy a lot of cultural relics. The Egyptian had no choice but ask the UN for help. Therefore, a international cooperation about how to protect the cultural relics began, which involved the time length about 20 years and a large amount of fund. Then, the problems was solved. 1.
