2学情分析二年级学生活泼可爱,思维独特,喜欢按照自己的想法自由地表现画面。好奇心强,爱表现自己,但动手能力较差,只能用简单的工具和绘画材料来稚拙地表现自己的想法。本课以学生亲切、熟悉的名字为题材,更好的激发学生的表现欲望和独创思维,让学生能够自信、大胆、自由地通过美术形式表达想法与感情。3重点难点重点:设计具有自己特色的名字。难点:能对名字的字形进行分析,巧妙地运用笔画特征进行想象设计。教学活动
四、说教学方法: 在教学活动中,我积极树立“以学生为主体”的教学思想,发挥学生的主动精神,使之成为学习的主人。因此,我设计的教法是:创设情境,自主探究、朗读感悟、启发想象等方法,引导学生主动参与到学习活动中。 我们常说:“现代的文盲不是不识字的人,而是没有掌握学习方法的人”,因而在教学中要特别重视学法的指导。学生对神话故事兴趣浓厚,尤其对神话故事中的英雄人物更是情有独钟,有较强的表达欲望。为此,我设计的学法是:采用自读自悟,尝试探究。抓住文本中的重点词句,读、说、讲多种学习方式相结合,在老师的引导下主动地富有个性地学习。
1.平行四边形和梯形都是四边形。师:要想研究它们,先来观察一下,这两种图形有什么共同的特点?学生说明,教师板书:四边形(于板贴平行四边形后),四边形(于板贴梯形后)。2.平行四边形和梯形都有对边平行。师:还有什么共同点?学生指黑板图形说明平行四边形和梯形中平行的对边。师:这是我们通过观察出来的,真的是这样吗?师:纸上(见上图)就有一个平行四边形和一个梯形.验证一下它们的对边平行吗?拿出你的工具开始吧!(学生操作,指生实物投影就图说明。)师:通过验证,说明了什么呢?有同样的发现吗?3.形成概念。(1)平行四边形。师:刚才我们验证了一个平行四边形和一个梯形,那么其它的平行四边形或梯形是不是也这样呢?这有3个平行四边形。课件呈现:3个平行四边形师:第一个我们刚才验证过了,用电脑再来验证其他两个。
尊敬的各位老师,同学们:大家好!。今天,我国旗下讲话的题目是:继承和发扬中华民族传统文化。“中庭地白树栖鸦,冷露无声湿桂花。今夜月明人尽望,不知秋思落谁家?”在刚刚过去的中秋节里,我们要收获的不仅仅是美味的月饼,更重要的是从中获取的我国的传统文化,作为新一代的社会主义接班人,这无疑是我们的重任。中秋节是一个传统节日,它的历史悠久同其他传统节日一样,经历了富有中国传统文化色彩演绎的辉煌路程。早在《周礼》一书中就出现了“中秋”一词,这个节日蕴涵的丰富民族文化,更给我们留下了一份宝贵的精神文化遗产。“每逢佳节倍思亲。”对于一个传统的团圆日子,中秋节更是要一家人团聚在一起,赏月,谈笑。因此才在这样一个节日,发扬敬老孝亲,感恩父母的美德,也应该是中秋文化的范畴。中秋又是一个充满诗意的节日。古往今来,关于中秋的诗词数不胜数,无数文人墨客在中秋留下了千古名篇,给中秋赋予了一种唯美的浪漫色彩,这也是我国的传统文化。而对于我们中华儿女来说,今年的中秋月格外圆。天宫二号在这天夜里半月升空,开始它探索天宇的征途。

This happens because the dish soap molecules have a strong negative charge, and the milk molecules have a strong positive charge. Like magnets, these molecules are attracted to each other, and so they appear to move around on the plate, taking the food coloring with them, making it look like the colors are quickly moving to escape from the soap.Listening text:? Judy: Oh, I'm so sorry that you were ill and couldn't come with us on our field trip. How are you feeling now? Better?? Bill: Much better, thanks. But how was it?? Judy: Wonderful! I especially liked an area of the museum called Light Games.it was really cool. They had a hall of mirrors where I could see myself reflected thousands of times!? Bill: A hall of mirrors can be a lot of fun. What else did they have?? Judy: Well, they had an experiment where we looked at a blue screen for a while, and then suddenly we could see tiny bright lights moving around on it. You'll never guess what those bright lights were!? Bill: Come on, tell me!? Judy: They were our own blood cells. For some reason, our eyes play tricks on us when we look at a blue screen, and we can see our own blood cells moving around like little lights! But there was another thing I liked better. I stood in front of a white light, and it cast different shadows of me in every color of the rainbow!? Bill: Oh, I wish I had been there. Tell me more!? Judy: Well, they had another area for sound. They had a giant piano keyboard that you could use your feet to play. But then, instead of playing the sounds of a piano, it played the voices of classical singers! Then they had a giant dish, and when you spoke into it, it reflected the sound back and made it louder. You could use it to speak in a whisper to someone 17 meters away.? Bill: It all sounds so cool. I wish I could have gone with you? Judy: I know, but we can go together this weekend. I'd love to go there again!? Bill: That sounds like a great idea!

The grammatical structure of this unit is predicative clause. Like object clause and subject clause, predicative clause is one of Nominal Clauses. The leading words of predicative clauses are that, what, how, what, where, as if, because, etc.The design of teaching activities aims to guide students to perceive the structural features of predicative clauses and think about their ideographic functions. Beyond that, students should be guided to use this grammar in the context apporpriately and flexibly.1. Enable the Ss to master the usage of the predicative clauses in this unit.2. Enable the Ss to use the predicative patterns flexibly.3. Train the Ss to apply some skills by doing the relevant exercises.1.Guide students to perceive the structural features of predicative clauses and think about their ideographic functions.2.Strengthen students' ability of using predicative clauses in context, but also cultivate their ability of text analysis and logical reasoning competence.Step1: Underline all the examples in the reading passage, where noun clauses are used as the predicative. Then state their meaning and functions.1) One theory was that bad air caused the disease.2) Another theory was that cholera was caused by an infection from germs in food or water.3) The truth was that the water from the Broad Street had been infected by waste.Sum up the rules of grammar:1. 以上黑体部分在句中作表语。2. 句1、2、3中的that在从句中不作成分,只起连接作用。 Step2: Review the basic components of predicative clauses1.Definition
Step 7: complete the discourse according to the grammar rules.Cholera used to be one of the most 1.__________ (fear) diseases in the world. In the early 19th century, _2_________ an outbreak of cholera hit Europe, millions of people died. But neither its cause, 3__________ its cure was understood. A British doctor, John Snow, wanted to solve the problem and he knew that cholera would not be controlled _4_________ its cause was found. In general, there were two contradictory theories 5 __________ explained how cholera spread. The first suggested that bad air caused the disease. The second was that cholera was caused by an _6_________(infect) from germs in food or water. John Snow thought that the second theory was correct but he needed proof. So when another outbreak of cholera hit London in 1854, he began to investigate. Later, with all the evidence he _7_________ (gather), John Snow was able to announce that the pump water carried cholera germs. Therefore, he had the handle of the pump _8_________ (remove) so that it couldn't be used. Through his intervention,the disease was stopped in its tracks. What is more, John Snow found that some companies sold water from the River Thames that __9__________________ (pollute) by raw waste. The people who drank this water were much more likely _10_________ (get) cholera than those who drank pure or boiled water. Through John Snow's efforts, the _11_________ (threaten) of cholera around the world saw a substantial increase. Keys: 1.feared 2.when 3. nor 4.unless 5.that/which 6.infection 7.had gathered 8.removed 9.was polluted 10.to get 11. threat
Step 5: After learning the text, discuss with your peers about the following questions:1.John Snow believed Idea 2 was right. How did he finally prove it?2. Do you think John Snow would have solved this problem without the map?3. Cholera is a 19th century disease. What disease do you think is similar to cholera today?SARS and Covid-19 because they are both deadly and fatally infectious, have an unknown cause and need serious public health care to solve them urgently.keys:1. John Snow finally proved his idea because he found an outbreak that was clearly related to cholera, collected information and was able to tie cases outside the area to the polluted water.2. No. The map helped John Snow organize his ideas. He was able to identify those households that had had many deaths and check their water-drinking habits. He identified those houses that had had no deaths and surveyed their drinking habits. The evidence clearly pointed to the polluted water being the cause.3. SARS and Covid-19 because they are both deadly and fatally infectious, have an unknown cause and need serious public health care to solve them urgently.Step 6: Consolidate what you have learned by filling in the blanks:John Snow was a well-known _1___ in London in the _2__ century.

The grammar of this unit is designed to review noun clauses. Sentences that use nouns in a sentence are called noun clauses. Nominal clauses can act as subject, object, predicate, appositive and other components in compound sentences. According to the above-mentioned different grammatical functions, nominal clauses are divided into subject clause, object clause, predicate clause and appositive clause. In this unit, we will review the three kinds of nominal clauses. Appositive clauses are not required to be mastered in the optional compulsory stage, so they are not involved.1. Guide the students to judge the compound sentences and determine the composition of the clauses in the sentence.2. Instruct students to try to learn grammar by generalizing grammar rules, controlling written practice, and semi-open oral output.3. Inspire the students to systematize the function and usage of noun clause1.Instruct students to try to learn grammar by generalizing grammar rules, controlling written practice, and semi-open oral output.2.Inspire the students to systematize the function and usage of noun clauseStep1: The teacher ask studetns to find out more nominal clauses from the reading passage and udnerline the nominal clauses.
2,解决三个圆片能摆出的数。小精灵聪聪也给大家提问题了:(课件出示:你能用三个圆片表示不同的数吗?)你们回答他,能不能?(1)现在请小朋友们自己动手摆一摆,并且不自己摆出来的数写在老师发给你们的纸上,看谁摆的又快又对。(2)汇报结果:你摆了几个数?分别是什么?是怎么摆的 ?这个活动的设计是为了培养学生的动手操作能力,提高学生学习数学的热情。利用自己总结出来的方法来进行操作,让学生体会到成就感。通过学生的汇报,培养学生的语言表达能力,让学生的手,脑,口的能力同时得到了锻炼。3,小朋友们真棒,现在我们不摆圆片,你能不能在脑子里想着摆圆片的方法,在纸上写出四个圆片都能表示那些数字呢 ?这个活动的设计,是让学生从操作走向有序的思维,让学生有条理的思考问题,将数学抽象化。
今天我说课的内容是人教版一年级数学下册第三单元《分类与整理》。我打算从说教学内容、说教学目标、说教学重难点、说教具准备、说教法学法和说教学过程等方面进行说课。一、 说教学内容一年级数学下册第三单元《分类与整理》要求学生在分类的基础上用自己的方式呈现整理的结果,但又不是正式的学习统计图和统计表,它是为以后学习统计图和统计表打下基础。二、 说教学目标一年级的心理特点和有具体到抽象的认知规律,我确定以下的教学目标:1.使同学能按照给定的标准或自己选定的标准对事物进行分类;能对分类结果进行整理,能够用自己的方式(文字、图画、表格等)呈现分类的结果;能对数据进行简单的分析,能根据数据提出并回答简单的问题。2.在小组交流合作中学习,经历收集信息、分类、统计的过程,体会对同一事物按单一标准分类的一致性。三、说教学重难点根据教材的编排和学生年龄特点,我认为本节课的重点是按单一标准对事物进行分类,本节课的难点是对分类结果进行整理,完成简单的统计活动,也就是能根据结果提出问题,回答问题。针对本节课的重难点,我设计的突破方法是首先通过把黑板上图形摆放整齐,让学生体会分类的意义和作用,然后创设情境,让学生在讨论合作交流中体会按单一标准对事物进行分类得到结果的一致性,最后对分类结果进行整理,完成统计活动。
一、说教材《古诗三首》是统编小学语文三年级下册第三单元中的第一篇课文。本课有三首古诗。宋代诗人王安石的《元日》一诗中作者通过“爆竹声”、“屠苏酒”“换桃符”以及开始送暖的春风等新年特有景物的描绘,展现了人们在春节的欢快情景和万象更新的情景。结句“总把新桃换旧符”既是写当时的民间习俗,又寓含除旧布新的意思。这首诗是通过新年新气象的描写,抒写自己执政变法,除旧布新,强国富民的抱负和乐观自信的情感。《清明》一诗中作者杜牧描写的是中国传统节日清明时节的景象,借春雨绵绵寄托了作者对逝去亲人的惆怅感伤无限哀思。这是一首叙事诗,寓情于景,同时这也是一首七言绝句,语言十分简洁,通俗易懂,音韵和谐。

一、基本情况 近年来,区政府高度重视农村集体经济发展,紧紧围绕“五水共治”“三改一拆”、美丽乡村建设等重点工作,全力推动农业农村经济转型升级,农村集体经济保持稳步发展,各项经济指标均超过预定的工作目标。 (一)加大财政补助力度。建立村级运转财政补助机制,*年开始连续*年对行政村实行运转补助,累计投入金额*亿元,有效确保了行政村的正常运转。加大对农村地区环境长效管理和农村河道保洁的经费保障力度,每年安排专项资金用于河道路网环境卫生清理,农村生活污水处理、水利等基础设施长效维护,进一步改善和提高了农村地区人居环境。积极落实保障“一事一议”财政奖补项目,*年安排资金*万元支持*个村级公共设施项目建设,加快了基础设施、公共服务向农村覆盖延伸,改善了农民生产生活条件。 (二)实施农村环境整治。*年开始,区政府制定实施三年美丽乡村行动计划,*年对龙坞茶镇*个村实施美丽乡村升级版的整治建设,*年又启动*片*个村、*镇*个村的全域化美丽乡村建设,*、*小集镇综合整治也带动了*等*个村的整治建设。农村地区的环境面貌、设施配套和道路交通得到了有效的提升,为壮大集体经济创造了良好的条件。 (三)开展农村土地流转。从今年年初开始,在*、*地区开展农村土地承包经营权流转工作,累计流转土地约*万亩,并已引进两家规模企业,发展现代农业产业园区。通过现代产业园的引进带动,将提升村集体建设用地和现有房产的潜在价值与经济收益,为村集体经济的进一步发展拓展了渠道。 (四)启动整村连片搬迁。近年来,区政府花大力气、大手笔对*、*部分行政村实施整村搬迁,着力通过引进大项目、大平台,促进农村集体经济发展。*等项目已经确定落户*村和*村,*景区打造和*新区建设将覆盖*村、*村等。通过整村搬迁后大项目的引进,为集体经济的发展壮大带来了前所未有的机遇。
三、制作统计图教师:事先我们一起搜集了这几年中我们班同学家庭拥有计算机的情况,并制成了统计表,请谁来介绍一下。(学生利用事先制成的统计表介绍数据)如果请你将它制作一份折线统计图,你有信心完成吗?小组讨论:你认为在制图时应做哪些工作?有什么注意点?(学生小组讨论后交流)在交流中,教师顺应学生回答,并相应介绍折线统计图各部分名称:(1)横轴:一般用于标明日期的前后;(2)纵轴:标明数据,反映单位长度表示的数据大小,一般最高数据比统计到的最高数据稍高一些;(3)制表日期和单位。学生独立在练习之上尝试练习。教师指名演示,同学互相评价并改正。统计分析:从这张统计图上你可以获得哪些信息?学生相互交流,也可以提问请同学回答。
二、说教法从教学内容来看,统计教学以探究研讨法为主。如设计中进行下个月进货的决策时,对已有的销售数据进行统计学上的分析外,其结果能对下一步的科学决策提供依据,体现统计在实际生活中的作用。从教学对象来看,小学中年级多用引导发现法、尝试教学法。随着年龄的增长,学生对社会问题也会越来越好奇和关心,因此素材的选择加强了联系社会生活实际,如设计垃圾调查与研究等题材,潜移默化地对学生进行保护环境等社会问题任何一节数学课都是多种教学方法的综合运用,如谈话法、讲解法等的有机结合!三、说学法在教学互动过程中,引导学生探索、、交流、观察、猜测、归纳等方法,培养学生的观察能力、分析能力及合作能力。因为是统计课,课前要去收集、整理实例,为课内互相交流积累素材。四、说教学过程(一)情境创设,复习旧知学校要购买一批体育器材,现在要调查同学们对体育运动的爱好。出示402班学生的纵向单式统计图情况。之后收集、整理、绘制本班学生的统计情况。
