《卖火柴的小女孩》统编教材三年级上册第三单元的第一篇精读课文,是丹麦作家安徒生的著名童话。讲述了在下着大雪的大年夜,一个为了生活被迫卖火柴的小女孩冻死街头的故事。表达了作者对当时黑暗社会的痛恨,对贫苦人民的深切同情。文章虚实交替,美丽的幻象和残酷的现实更迭出现,是这篇童话的特点。本文原是人教版六年级下册第四单元“学习外国名篇名著”中的一篇文章,旨在引导学生感知外国作品的特点,理解含义深刻的句子,感受卖火柴的小女孩悲惨的命运,体会作者表达的思想感情。统编教材将文章编排在三年级,“感受童话丰富的想象”为本单元的语文要素,旨在引导学生发现幻象与愿望之间的关系,感受童话丰富的想象,帮助学生建立对童话体裁的初步认识。

【教学目标】1、了解方程、不等式、函数的图像之间的联系;2、掌握一元二次不等式的图像解法;【教学重点】1、 方程、不等式、函数的图像之间的联系;2、 一元二次不等式的解法。【教学难点】 一元二次不等式的解法。【教学设计】 1、从复习一次函数图像、一元一次方程、一元一次不等式的联系入手;2、类比观察一元二次函数图像,得到一元二次不等式的图像解法;3、加强知识的巩固与练习,培养学生的数学思维能力。【课时安排】 2课时(90分钟)【教学过程】一、一元二次不等式的解法² 复习回顾1、根据初中所学知识,填写下面表格: △>0 △=0△<0y=ax²+bx+c (a>0)的图像ax²+bx+c=0 (a>0)的根有 2 个根有 1 个根有 0 个根2、观察二次函数y=x²-5x+6的图像,回答下列问题:(1)当y=0时,x取什么值?(2)二次函数y=x²-5x+6的图像与x轴交点的坐标是什么?(3)当y<0时,x的取值范围是什么?总结:由此看到,通过对函数y=x²-5x+6的图像的研究,可以求出不等式x²-5x+6>0与x²-5x+6<0的解集
①阐发话题式:就是用简练的语言对所给话题材料加以概括和浓缩,并找到一个最佳切入点加以深层次阐述。吉林一考生的满分作文《漫谈“感情”“认知”》的题记是:“同是对‘修墙’‘防盗’的预见,却产生‘聪明’或‘被怀疑’的结果。‘感情’竟能如此地左右着‘认知’,心的小舟啊,在文化的河流中求索。”这个题记通过对材料的简单解释,将“感情”与“认知”二者的关系诠释得非常明白,也点明了作者的态度和议论的中心。②诠释题目式:所拟题目一般都具有深刻性特点,运用题记形式对题目进行巧妙而又全面的诠释。云南一考生的满分作文《与你同行》的题记是:“他们一路同行,一个汲着水,一个负着火,形影相随。在他们携手共进时,就产生了智慧。”这个题记形象而深刻地对“与你同行”这个题目进行了解释,言简意赅,表明了考生对感情和理智关系的认识。
3、课堂小结,强化认识。(2—3分钟)通过总结本课的知识,简单的用三个概念三个关系,简明扼要的总结出本节课的知识,突出本框题的重难点。其中重点给学生梳理一下哲学的含义,使学生在学习的最后对于哲学有一个全面而准确的理解,强化学生对于哲学的认识。4、课堂练习针对高中学生初步接触哲学,运用哲学思维来分析哲学问题的能力还需要今后的培养,我进行了分层的方式来设计习题,这样设计一方面符合学生认知的能力,由简单到困难,一步步的深入,另一方面,在练习的过程中,也可以使学生巩固基础知识,使学有余力的学生继续提高,充分考虑到学生的实际情况。5、板书设计为了强化教学效果,我会在授课的过程中适时的书写板书,我的板书设计总的来说是以简洁明了的形式展示,便于学生一目了然的把握本节课的重难点,也可以建立知识间的联系,便于学生形成完整的知识体系。
2、讲授新课:(35分钟)通过教材第一目的讲解,让学生明白,生活和学习中有许多蕴涵哲学道理的故事,表明哲学并不神秘总结并过渡:生活也离不开哲学,哲学可以是我正确看待自然、人生、和社会的发展,从而指导人们正确的认识和改造世界。整个过程将伴随着多媒体影像资料和生生对话讨论以提高学生的积极性。3、课堂反馈,知识迁移。最后对本科课进行小结,巩固重点难点,将本课的哲学知识迁移到与生活相关的例子,实现对知识的升华以及学生的再次创新;可使学生更深刻地理解重点和难点,为下一框学习做好准备。4、板书设计我采用直观板书的方法,对本课的知识网络在多媒体上进行展示。尽可能的简洁,清晰。使学生对知识框架一目了然,帮助学生构建本课的知识结构。5、布置作业我会留适当的自测题及教学案例让同学们做课后练习和思考,检验学生对本课重点的掌握以及对难点的理解。并及时反馈。对学生在理解中仍有困难的知识点,我会在以后的教学中予以疏导。
五.说教学过程:(重点)1.课题引入:课堂探究导入新课。采用教材现成的探究活动导入新课,既“温故”又“知新”,还节约了课堂有效时间。2.讲授新课:(20-25分钟)本课的重难点是关于哲学基本问题的解释,我引用一个很著名的学生也略知一二的唯心主义观点的例子(课堂探究1)顺利进入本课重要知识点的学习,采用案例教学,激发学生的兴趣以及探究问题的欲望,学习哲学基本问题的第一个方面,并用问题和练习形式巩固知识,强化学生易错已混知识点;课堂探究2,同样引用哲学上的著名案例让学生分析探究思考以及合作交流,学生趣味浓厚,主动深入学习本课知识,达到预期教学目的。此时,本课的重点知识教学完成。关于本课的第二个知识点“为什么思维和存在的关系问题是哲学的基本问题”采用学生自主阅读、合作交流的方法,归纳总结,完成本知识目标。3.课堂反馈、知识迁移(10-15分钟)采用学生总结、随堂练习等形式巩固本课知识,同时检验教学效果。可使学生更深刻的理解教学重点。

Listening and Speaking introduces the topic of “talking about how to become an astronaut”. This period is aimed to inform students some details about the requirements of being an astronaut. Students can be motivated and inspired by the astronauts. Teachers ought to encourage students to learn from them and let them aim high and dream big.Listening and Talking introduces the theme of "talk about life in space". This part also informs students more details about life in space and can inspire students to be curious about this job. 1. Guide students to listen for numbers concerning dates, years and ages etc2. Cultivate students' ability to talk about how to become an astronaut and life in space ; 3. Instruct students to use functional sentences of the dialogue such as “ first of all, I am not sure, so what might be .. I guess.. I wonder…I am curious…)appropriately.1. Guide students to understand the content of listening texts in terms of the whole and key details; 2. Cultivate students' ability to guess the meaning of words in listening; discuss with their peers how to become a qualified astronaut and describe the life in space.Part 1: Listening and SpeakingStep 1: Lead inPredictionThe teacher can ask students to predict what the listening text is about by looking at the pictures.About how to become an astronaut./the requirements of an astronautStep 2: Then, play the radio which is about an interview a. And after finishing listening for the first time, the students need to solve the following tasks.

Everybody wants to get wealth.In today’s material world,making money or becoming wealthy symbolizes a person’s success and capability. Many people just make every effort, pay any price to attain greater wealth. With money,they can buy nice, large apartments in nice neighborhood. With money they can own luxurious cars. Wealth seems to bring all happiness in life.But is wealth the only road to happiness? Not really. There are many things in the world, which are beyond the means of money, such as friendship, love, health and knowledge. People are so preoccupied with struggling for money that they have no time or would not take the time to form or maintain friendship. What happiness can they feel living as lonely miserable creatures without love or friends in the world even if they accumulate tremendous wealth?In my opinion, people can’t do anything without money, but money is not everything. What money will bring you depends on your personal belief and goal in life. If you are kind enough to help others, especially the poor, money is a good thing to you. With it, you can do much more for the benefit of people and your country, and it will add to your own happiness. If you want money just for your own needs, you’ll never be satisfied or happy. In a word,you should have money spent for more people. Only then can money be the source of your happiness.Step 8 Homework4 students in a group, one acts Roderick, one Oliver, one servant and the fourth one acts Henry Adams, then listen to the tape, pay more attention to the difference between American English and British English in pronunciation, stress, tone.
【参考范文】Narrator:(Henry is smiling as he leaves the restaurant. As he is walking down the street, he sees a sign for a place that cuts hair. He decides to get it cut. )H=Henry;B=Barber;R=rude manH:Good afternoon, I'd like to get a cut, if I may. (The barber looks at Henry's hair and continues cutting another man's hair. )Er, I'd really like a haircut. As you can see it's much too long. B:(in a rude manner) Yes, I can see that. Indeed, I can.

【教学过程】一、导入1、复习歌曲《夏日泛舟海上》教师:同学们,我们上节课学习了一首描写夏天在海上泛舟的歌曲,让我们一起再来回味一下那个充满快乐的夏日吧。师生随《夏日泛舟海上》伴奏演唱歌曲。(课件:播放《夏日泛舟海上》伴奏音频)2、导入新课教师:《夏日泛舟海上》用声乐的形式为我们展现了一个快乐的夏日,其实描写夏日情景的音乐作品还有很多,我们今天来欣赏一首器乐作品,它也描绘了夏,我们听听它描绘了一个什么样的夏呢?(学生自由回答)二、分析《六月——船歌》音乐及曲式特点1、教师:现在,请同学们闭上眼睛,用心再听听这首作品,告诉我你印象最深的旋律是哪句旋律?2、复听《六月——船歌》。学生自由回答。3、教师:看来同学们印象最深的都是第一句,让我们一同用随老师的琴声哼唱一下这句旋律。4、大屏幕出示第一句旋律谱例。(课件:《六月——船歌》第一段主题旋律谱例及对应音频)5、教师:大家哼唱了这句旋律,请大家结合谱例,说说这句旋律在音乐表现上有什么样的特点?学生自由回答。
教学过程:1、钢琴准备练习弹奏《哈农钢琴练指法》的第1条、第38条练习,要求学生弹出富有歌唱性的音色,第38条音阶准备练习中,弹出歌唱新的上行、下行的音阶。2、导入新课:《六月—船歌》已经基本练习过了,由学生向老师总结一下关于已经掌握的《六月—船歌》的相关知识内容。3、教师补充学生的总结,并注意指导学生对作品整体形态的把握。阐述作品的创作背景和相关的内容。让学生弹奏一遍《六月—船歌》,并和学生一起描述作品刻画的画面:夏日的夜晚乘小舟荡漾在微波上,沉浸在幸福中,敬请享受大自然的恩赐。4、弹奏的触键要领:演奏时要首先做到将旋律从心底悠然自得的歌唱出来,努力通过指尖控制键盘,手指尽量贴键,力量要从一个指尖转移到另一个指尖,用这样的方法把旋律线条从“指尖”流出来,同时要学会聆听,善于分辨弹出的声音是否达到如歌的地步,是否表达出要创造的意境。
一、欣赏《六月——船歌》1、播放视频《六月——船歌》。(课件:钢琴演奏版《六月——船歌》的视频)2、教师:这是一首钢琴作品,哪位同学可以告诉我听完这首作品后脑海里产生了什么样的画面?学生自由回答。3、教师:大家说得很好,这首作品名字叫《六月——船歌》,是我们很熟悉的俄国作曲家柴可夫斯基的作品,大家还记得柴可夫斯基有什么代表作品吗?学生自由回答。二、作曲家简介:柴可夫斯基是著名的俄国作曲家、指挥家,有“旋律大师”的美誉。他的音乐创作具有浓厚的俄罗斯气息,芭蕾舞剧《天鹅湖》、《睡美人》,交响曲《悲怆》都是他的代表作品,这首《六月——船歌》也是他的代表作品,是他创作的钢琴套曲《四季》中的一首。(课件:制作包括柴可夫斯基生平介绍、头像,《天鹅湖》《悲怆》主题音频的 PPT。)
明确读的要求,对一年级的学生一说,十分必要。这样可以提高读书效率,有利于养成良好的阅读习惯,于是,在导入新课后,我马上提了自读要求:读准了音,读通句子,标出自然段。
1、故事引入,了解学情。小朋友们,老师给大家讲件有趣的事。有个外国小朋友来到中国,他需要学习中文,也就是学认我们中国字。有一天,他才学了几个字,就对老师说:“老师,这几个字怎么都长得一样呢?又难读,又难记,学汉字太难了。”我们来看看,是哪几个字让这位小朋友这样发愁呢?(课件显示6个生字)(有的学生已经在轻声读)老师还没教,有的小朋友就会读,能说说你们是怎么认识的吗?(注意表扬通过不同方法认识字的学生,意在扩散好的识字途径。)仔细看看这六个字,认会1个的举手。认会2个的呢?有6个都认会的吗?(面对先认会部分字的学生)干脆请你们来给周围的小伙伴当小老师吧,谁有困难,你就像老师一样,帮帮他们,好吗?(教师在行间巡视)
2、教师:这两个小动物它们今天还带来了一个故事哦,请小朋友们来听一听这个好听的故事吧!教师讲述故事内容。3、教师提问:教师:小公鸡和小鸭子在做什么呢?当鸭子啄不到虫子的时候是谁来帮他啄的呢?小公鸡是怎么样帮助小鸭子的呢?小公鸡不会游泳,是谁来救他的?小鸭子又是怎么样救小公鸡的呢?教师小结:小鸡和小鸭子它们是一对好朋友,他们互相关心、互相帮助。
