The theme of this section is to express people's views on studying abroad. With the continuous development of Chinese economic construction, especially the general improvement of people's living standards, the number of Chinese students studying abroad at their own expense is on the rise. Many students and parents turn their attention to the world and regard studying abroad as an effective way to improve their quality, broaden their horizons and master the world's advanced scientific knowledge, which is very important for the fever of going abroad. Studying abroad is also an important decision made by a family for their children. Therefore, it is of great social significance to discuss this issue. The theme of this section is the column discussion in the newspaper: the advantages and disadvantages of studying abroad. The discourse is about two parents' contribution letters on this issue. They respectively express their own positions. One thinks that the disadvantages outweigh the advantages, and the other thinks that the advantages outweigh the disadvantages. The two parents' arguments are well founded and logical. It is worth noting that the two authors do not express their views on studying abroad from an individual point of view, but from a national or even global point of view. These two articles have the characteristics of both letters and argumentative essays1.Guide the students to read these two articles, and understand the author's point of view and argument ideas2.Help the students to summarize the structure and writing methods of argumentative writing, and guides students to correctly understand the advantages and disadvantages of studying abroad3.Cultivate students' ability to analyze problems objectively, comprehensively and deeply
This section guides students to pay attention to the typical context of vocabulary use, helps students accumulate vocabulary around the key vocabulary of this unit, and uses the learned words and word chunks in different contexts to deeply understand their meaning and usage, so as to achieve the purpose of review and consolidation.The teaching design activities aim to guide students to pay attention to the typical context in which the target vocabulary is used, as well as the common vocabulary used in collocation, so that students can complete the sentence with correct words. In terms of vocabulary learning strategies, this unit focuses on cultivating students' ability to pay attention to collocation of words and to use word blocks to express meaning.For vocabulary learning, it is not enough just to know the meaning of a single word, but the most important thing is to master the common collocations of words, namely word blocks.Teachers should timely guide students to summarize common vocabulary collocation, such as verb and noun collocation, verb and preposition collocation, preposition and noun collocation, and so on.1. Guide students to understand and consolidate the meaning and usage of the vocabulary in the context, 2. Guide the students to use the unit topic vocabulary in a richer context3.

種子對于幼兒來說并不陌生,但是幼兒所見到的大部分都是農(nóng)作物的種子,都是靠人類來種植的。在自然界中還有許許多多的野生植物,他們有各種各樣奇特的種子,能借助于外界或自身的力量遍布世界,這對于生活在城市的幼兒相對就比較陌生了,然而正是因為幼兒在這方面經(jīng)驗的欠缺,所以能使幼兒產(chǎn)生更濃厚的探索興趣。《種子的旅行》這一活動,通過讓幼兒收集種子實(shí)物和種子的圖片,通過各種途徑積累相關(guān)的知識經(jīng)驗,在此基礎(chǔ)上充分利用課件和錄像資料,讓幼兒了解種子的神奇、了解種子傳播的秘密。根據(jù)活動內(nèi)容的特點(diǎn)和幼兒的知識經(jīng)驗情況,確定目標(biāo)如下:1、初步了解幾種常見種子的傳播方式,知道種子的外部形態(tài)及其傳播方式之間的關(guān)系。2、能根據(jù)種子的傳播方式對種子進(jìn)行分類。3、知道種子傳播的目的是為了繁衍后代。
我的整個教學(xué)過程分為五步:第一步:品嘗食物,談?wù)勊晕骷t柿的去向在此步驟中我運(yùn)用了談話法,我先讓孩子們品嘗西紅柿,然后提出問題西紅柿去了哪里,讓孩子們說一說西紅柿的去向,目的在于擴(kuò)展孩子的思維,激發(fā)孩子們對食物消化過程的探究欲望。第二步:傾聽故事,說說西紅柿的消化過程在此步驟中使用了故事課件,通過傾聽故事觀看故事圖片,讓孩子更加直觀的了解食物消化過程。第三步:觀看圖片,講講各種消化系統(tǒng)功能我運(yùn)用了觀察法和討論法,讓孩子們通過已有的經(jīng)驗交流,并通過直觀的觀察去了解各消化系統(tǒng)的名稱及功能。第四步:拼圖活動,擺擺人體消化系統(tǒng)模型這一環(huán)節(jié)是在前一環(huán)節(jié)的基礎(chǔ)上進(jìn)行鞏固復(fù)習(xí),孩子們自由選擇一種消化器官進(jìn)行拼圖,并簡單介紹所拼器官的名稱及功能。
活動準(zhǔn)備:材料準(zhǔn)備——故事錄音、PPT知識經(jīng)驗準(zhǔn)備——幼兒對自然界中的各種現(xiàn)象有一定的認(rèn)知基礎(chǔ)。重點(diǎn)難點(diǎn):活動重、難點(diǎn)——了解水的三態(tài)及變化需要的條件。 一、說說生活中的水1、說說生活中哪些地方有水,水的作用是什么。2、提升:美容院用水蒸汽擴(kuò)張毛孔;制造氣氛桑拿院用水蒸汽幫助減肥;舞臺上用水制成的干冰……水的用處真正大。3、說說“水魔法師”能變成哪些樣子。4、介紹故事名稱,引導(dǎo)幼兒仔細(xì)聆聽。
二、重點(diǎn)及難點(diǎn): 重點(diǎn):感知8以內(nèi)的數(shù)量 難點(diǎn):能排除物體大小、顏色的干擾,理解數(shù)的實(shí)際意義。三、活動準(zhǔn)備: 1、紙箱制戰(zhàn)斗機(jī)(與幼兒人數(shù)相等)內(nèi)有一個,炮彈8發(fā)?! ?、惡魔城堡情境、小動物若干。四、活動流程: 語言引導(dǎo)、激發(fā)興趣→情景練習(xí)、感知數(shù)量→排除干擾、鞏固練習(xí)。五、活動過程:(一)、語言引導(dǎo)、激發(fā)興趣 說明:請幼兒當(dāng)小小飛行員上藍(lán)天練本領(lǐng),登上飛機(jī)。
二是強(qiáng)化學(xué)生參與,當(dāng)好“拉風(fēng)”服務(wù)代言人。組建“小紅萌”等品牌志愿服務(wù)團(tuán)隊,緊密圍繞學(xué)生特點(diǎn)設(shè)計服務(wù)項目,以世界環(huán)境日、學(xué)習(xí)雷鋒日系列節(jié)日為契機(jī),引導(dǎo)各校少先隊員走出校門、進(jìn)村入戶參與環(huán)境衛(wèi)生、垃圾分類等社會實(shí)踐,在身體力行中增強(qiáng)學(xué)生的主體意識和責(zé)任觀念。2022年以來,組織中小學(xué)生深入村居(社區(qū))、農(nóng)村文化禮堂等地開展各類活動2000余次,參與志愿者達(dá)到3萬余人次。三是強(qiáng)化社會協(xié)同,當(dāng)好“拉風(fēng)”潮流主人翁。聯(lián)合市環(huán)保局、市少年宮等單位、社會組織共同開展實(shí)地參觀學(xué)習(xí)活動,發(fā)揮好環(huán)保能源公司、垃圾焚燒發(fā)電廠、科普館等資源場所作用,邀請現(xiàn)場技術(shù)人員答疑解惑,通過“大手牽小手”的形式傳授垃圾分類、回收、處理專業(yè)知識,家校政社多主體、多維度同頻共振,營造起“人人有責(zé)、人人參與”的濃厚氛圍。目前與20余家企業(yè)、場館形成定點(diǎn)聯(lián)系,已舉辦100余場次體驗活動。
同學(xué)們,老師們:早上好!今天,我國旗下講話的主題是“陽光體育與快樂校園同行”。為全面貫徹落實(shí)《中共中央國務(wù)院關(guān)于加強(qiáng)青少年體育增強(qiáng)青少年體質(zhì)的意見》精神,廣泛開展全國億萬學(xué)生陽光體育運(yùn)動,切實(shí)抓好我校學(xué)生的體育鍛煉工作,培養(yǎng)廣大學(xué)生熱愛體育、崇尚運(yùn)動的良好習(xí)慣,從本周起至XX年4月,我校將全面實(shí)施學(xué)生冬季長跑計劃。冬季長跑有什么好處?其實(shí)在人類文明的發(fā)源地之一、奧林匹克的故鄉(xiāng),古希臘就流傳著這樣的諺語:如果你想強(qiáng)壯,跑步吧;如果你想健美,跑步吧;如果你想聰明,跑步吧。歐美各國和原蘇聯(lián)都很推崇庫珀的《美國科學(xué)健身法》,其核心是:運(yùn)動項目的優(yōu)劣應(yīng)以耗氧量的大小為標(biāo)準(zhǔn),選擇項目依序為跑步、游泳、騎車、步行、原地跑和球類?,F(xiàn)在從科學(xué)角度講,長跑可提高呼吸系統(tǒng)和心血管系統(tǒng)機(jī)能;長跑能促進(jìn)血液循環(huán),有利于心情舒暢,精神愉快。長跑還對培養(yǎng)同學(xué)們克服困難、磨練吃苦耐勞的頑強(qiáng)意志具有良好的作用。尤其對冬季怕冷、愛睡懶覺的同學(xué)更是如此。我校如何實(shí)施冬季長跑?
按照心理學(xué)常識,幼兒對學(xué)習(xí)內(nèi)容產(chǎn)生興趣,就能自覺地排除內(nèi)外主客觀因素的干擾,集中注意力積極主動地投入學(xué)習(xí),把學(xué)習(xí)當(dāng)成愉快的事。因此,上課一開始進(jìn)行復(fù)習(xí)時,就設(shè)計這樣的導(dǎo)語:小朋友,我們已經(jīng)學(xué)了很多加減法了,今天老師要來考考你們,看誰最能干,(點(diǎn)出復(fù)習(xí)題)最先做出老師出的這些題,好嗎?在這種刺激下,人人都想當(dāng)老師眼中的小能手,興趣一下子就能調(diào)動起來。這是引導(dǎo)幼兒復(fù)習(xí)5以內(nèi)數(shù)的加減;這是復(fù)習(xí)6的組成。在新課學(xué)習(xí)中,通過可愛的動物圖片群和插入聲音的播放,激發(fā)幼兒學(xué)習(xí)新知的欲望,引導(dǎo)幼兒感知、探索得數(shù)是6的加法。這是引導(dǎo)幼兒觀察動物圖片,發(fā)現(xiàn)數(shù)量關(guān)系,學(xué)習(xí)5+1和1+5,初步引導(dǎo)通過組成計算得數(shù);然后出示4+2和2+4兩個算式,讓幼兒擺弄小棒探索得。

CASIO fx 82ESPLUS函數(shù)型計算器(如圖10-3),利用 · 鍵的第二功能產(chǎn)生隨機(jī)數(shù).操作方法是:首先設(shè)置精確度并將計算器顯示設(shè)置為小數(shù)狀態(tài),依次按鍵SHIFT 、 MODE、 2 ,然后連續(xù)按鍵 SHIFT 、 RAN# ,以后每按鍵一次 = 鍵,就能隨機(jī)得到0~1之間的一個純小數(shù). 采用“隨機(jī)數(shù)法”抽樣的步驟為: (1)編號:將總體中的N個個體編上號; (2)選號:指定隨機(jī)號的范圍,利用計算器產(chǎn)生n個有效的隨機(jī)號(范圍之外或重復(fù)的號無效),得到一個容量為n的樣本. 講解 說明 引領(lǐng) 分析 仔細(xì) 分析 關(guān)鍵 語句 觀察 理解 記憶 帶領(lǐng) 學(xué)生 分析 20
