一、教材分析行星的運動選自人教版普通高中物理必修2第六章第1節(jié)。本節(jié)教學既是前面《運動的描述》和《曲線運動》內(nèi)容的進一步的延伸和拓展,又能為后面學習萬有引力定律做鋪墊。在本章中占有較為重要的地位,具有承前啟后的作用。同時該節(jié)內(nèi)容也涉及大量物理史實、貼近學生生活和聯(lián)系社會實際的事實,可進一步培育學生的科學情感、精神和發(fā)展觀。(一)教學目標 1.知識與技能(1)知道地心說和日心說的基本內(nèi)容。(2.)掌握理解開普勒三大定律的內(nèi)容,并能應用。(3)理解人們對行星運動的認識過程是漫長復雜的,真理是來之不易的。2.過程與方法通過托勒密、哥白尼、第谷·布拉赫、開普勒等幾位科學家對行星運動的不同認識,了解人類認識事物本質(zhì)的曲折性并加深對行星運動的理解。3.情感、態(tài)度與價值觀(1)澄清對天體運動神秘、模糊的認識,掌握人類認識自然規(guī)律的科學方法。(2)感悟科學是人類進步不竭的動力。

一是資源優(yōu)勢。**地處黃河中游、陜北黃土高原丘陵溝壑區(qū),土地面積廣,光照時間長,晝夜溫差大,農(nóng)業(yè)資源稟賦優(yōu)越。光、熱、水、氣等生態(tài)氣候條件完全符合蘋果優(yōu)生區(qū)“七項指標”要求,處于中國蘋果產(chǎn)業(yè)帶的核心位置??v橫交錯的溝壑山川為現(xiàn)代畜牧業(yè)發(fā)展提供了天然的防疫隔離屏障,吸引了新希望、東方希望、伊利集團優(yōu)然牧業(yè)等企業(yè)集團投資建場;1100多萬畝洋槐林和500多種蜜源植物,是業(yè)界公認國內(nèi)最大的優(yōu)質(zhì)洋槐蜜蜜源基地和全國四大中蜂保護區(qū)之一;依托山地資源建成的“95式”日光溫室,比川地溫室光照**60-90分鐘,夜間棚內(nèi)最低氣溫提高3-5℃,采光更好、保溫性更強;夏季氣溫涼爽,氣候干燥,露地菜品質(zhì)好,香菇花菇出菇率高,具有反季節(jié)生產(chǎn)的優(yōu)勢。

大家能夠成為其中的一員,應該感到榮幸和自豪。希望大家一定要做好示范、當好表率,切實強化使命意識、責任意識,以勤奮、刻苦、嚴謹、專注的精神,盡快實現(xiàn)由干部到學員角色的轉(zhuǎn)換,盡量脫離本單位的工作,真正把自己作為一名農(nóng)學專業(yè)的學生,全身心投此次培訓學習當中,高標準、高質(zhì)量地完成好這次培訓任務。同時也懇請 老師們對學員們嚴格要求,加強培訓過程管理,確保廣大學員學到“真知”、取到“真經(jīng)”。

我說課的題目是小學道德與法治五年級上冊《自主選擇課余生活》。下面我將從教材分析、學情分析、教學目標與重難點、教法與學法、教學過程、板書設(shè)計6個方面進行說課。一、教材分析《自主選擇課余生活》是統(tǒng)編教材小學《道德與法治》五年級上冊第一單元第1課,共有三個話題,本節(jié)課學習的是第三個話題《過好我們的課余生活》,主要是引導學生課余生活的選擇既有興趣,又有意義,要學習規(guī)劃自己的課余生活,學會過好課余生活的方法,旨在引導學生能夠過好課余生活,讓課余生活促進學生的健康成長。二、學情分析自主選擇是學生的權(quán)利,也是成長過程中需要發(fā)展的能力。隨著年齡的增長和知識、經(jīng)驗的增多,學生對一些事情有了自己的看法,特別是希望能按照自己的想法安排課余生活。但是他們現(xiàn)在的課余生活大都是家長來主導,學生自主選擇課余活動的機會幾乎很少。因此,要幫助引導學生面對成長中的這個困惑,通過有效的教學能夠過好課余生活,讓課余生活促進學生的健康成長。三、教學目標與重難點基于教材、學情的分析,以及對小學道德與法治課程的理解,我確定了本節(jié)課的教學目標與重難點。教學目標我確定了三個。

一、聚焦產(chǎn)業(yè)興旺,積極推動一二三產(chǎn)融合發(fā)展 著力構(gòu)建以優(yōu)勢產(chǎn)業(yè)為主導、新興產(chǎn)業(yè)為帶動、特色農(nóng)業(yè)為補充的現(xiàn)代化農(nóng)業(yè)發(fā)展體系。圍繞優(yōu)勢特色產(chǎn)業(yè),夯實鄉(xiāng)村振興基礎(chǔ)。一是聚力產(chǎn)業(yè)集群,全力打造稻麥輪作生產(chǎn)基地,新流轉(zhuǎn)土地*畝,新建*家新型合作農(nóng)場。二是突出品牌提升,全力打造“一村一品”。規(guī)劃設(shè)計全鎮(zhèn)*個村形成了“一村一品”大循環(huán)串聯(lián),以特色農(nóng)產(chǎn)品為主,形成了各具特色的農(nóng)產(chǎn)品品牌,成立南通*天下農(nóng)產(chǎn)品有限公司,實現(xiàn)抱團發(fā)展,壯大村級經(jīng)濟。構(gòu)建電子商務公共服務中心、村級電商服務站等服務體系,發(fā)展“*天下電商+”、“直播帶貨”等新業(yè)態(tài),完善農(nóng)產(chǎn)品電商供應鏈物流配送體系,推動商貿(mào)、供銷、電商互聯(lián)互通,實現(xiàn)利潤*萬元。三是強化產(chǎn)業(yè)融合發(fā)展。建成全區(qū)首家鄉(xiāng)村振興產(chǎn)業(yè)聯(lián)盟中心,集農(nóng)產(chǎn)品展銷、電商直播、數(shù)字農(nóng)業(yè)、農(nóng)產(chǎn)品科普、新產(chǎn)品發(fā)布、農(nóng)產(chǎn)品檢測等為一體的智慧電商農(nóng)業(yè)展銷中心,中心周邊配套了*立方的冷庫和*平方米的倉庫。招引國家級農(nóng)業(yè)龍頭企業(yè)*等農(nóng)業(yè)企業(yè),*天下農(nóng)產(chǎn)品有限公司以及*鎮(zhèn)農(nóng)業(yè)產(chǎn)業(yè)聯(lián)盟和人才培訓基地,助農(nóng)增收。 二、聚焦生態(tài)宜居,打造人居環(huán)境優(yōu)美村莊 圍繞“提升環(huán)境治理水平,打造宜居生態(tài)*”的總體目標,堅持系統(tǒng)治理,實施“三大革命”。一是堅持治理生活垃圾,提升保潔能力,清運農(nóng)村生活垃圾*噸,打撈河道*條,路域割草*多公里,宅前屋后清理亂堆亂放*余處,整理枯死樹木*棵;清運廢舊農(nóng)膜*噸。二。堅持廁所革命,完成新建改廁*座,整改問題廁所*座。*村整村推進,正在全力攻堅。完成*戶污水管網(wǎng)納管。三是堅持“一村一特色、一村一亮點”,推進風貌革命,加大三棚和破落建筑的整治,全年整治三棚*處,拆除三棚*戶,完成*戶整治,打造了三處村級小游園。四是聚焦基礎(chǔ)設(shè)施,穩(wěn)扎穩(wěn)打夯實基礎(chǔ),實施*河*條生態(tài)河道建設(shè)*.*公里,鄉(xiāng)級河道生態(tài)覆蓋率增長率有新的提高。完成配套建筑物提檔升級*座,方涵改造*座,確保水系暢通,提高河道灌溉行洪能力;開展河道疏浚和村級土方工程,對淤積嚴重、環(huán)境臟亂差的溝河進行整治,將水環(huán)境整治向河道末端延伸。全鎮(zhèn)*個村計劃完成約*萬方土方。

“深入探究,把握主旨”這一步則是解決教學的重點難點,這里涉及到課文的深層意蘊,學生理解有難度,教師在通過問題引領(lǐng)學生探討的基礎(chǔ)上,還要適時啟發(fā)、點撥,因為教學時間有限,讓學生漫無邊際的討論,可能難以完成預定的教學任務,會使教學過程不完整。至于本文的寫作特點的教學視時間而定,有時間可以讓學生說一說,沒有時間用小黑板出示一下,讓學生了解就行,如果時間不夠,甚至可以不講。第三階段是“延伸練習,鞏固提高”。

(2).教學手段為了使我根據(jù)教材而設(shè)計的三個教學目標以及重點難點得以的突出和突破,達到最大化的展示境界,同時也為了配合以上我選擇的四種教法得以完滿實現(xiàn),我決定采用“多媒體”教學手段進行全程教學。利用電腦的信息容量大,操作簡便等優(yōu)點,形象生動的直觀展示教學內(nèi)容,不但提高學習效率和質(zhì)量,而且容易激發(fā)學生的學習興趣和調(diào)動學習的積極性。四、說學法我為學生設(shè)計了三個學習方法:1.讓學生學會在探究中學。通過“對黑人嚴酷處境的探究”和對文中重點語句的探究,培養(yǎng)學生在探究中學習的能力。2.讓學生學會在讀中學。通過“誦讀法”指導學生在誦讀過程中感受演講詞內(nèi)在的魅力,學會在讀中學。3.讓學生學會在練習中學。通過“課外延伸練習法”,對所學的知識進行運用,培養(yǎng)學生的創(chuàng)新和自學能力。

一、說教材1.教材分析《涉江采芙蓉》是新人教版必修二第二單元《古詩三首》中的一首。《古詩十九首》在中國古代詩歌的藝術(shù)手法上起著承前啟后的作用,在高中語文古詩教學中也起著承前啟后的作用。這首古體詩不論是藝術(shù)上,還是在思想上都已經(jīng)達到了十分純熟的境界。因此,它十分重要。2.說學情這首詩歌在內(nèi)容上難度不大,可以做多角度解讀。新課程標準鼓勵學生作個性化解讀,我們可以引導學生就此作些探討。學生通過小學、初中的系統(tǒng)學習和本冊古詩部分的集中學習,有了一定的古詩鑒賞能力,對源遠流長的中華文化也有了一些積淀,興趣漸濃,這是進一步引導學生熱愛古代詩歌、學習古代詩歌的一個前提。3.教學目標依據(jù)學生特點,教材特色以及新課標的要求,制定教學目標如下:(用多媒體展示)1、了解關(guān)于《古詩十九首》的文學常識;2、感受詩歌的思想內(nèi)涵;3、運用想象描摹詩歌的藝術(shù)畫面。

一、說教材《短歌行》是普通高中課程標準實驗教科書必修(二)第二單元的一篇略讀課文,本單元安排的是先秦到南北朝時期的詩歌?!抖谈栊小肥侵渭?、軍事家、文學家曹操的作品。詩中抓住“憂”字來寫詩人為什么“憂”,如何解“憂”,從而表達希望能夠招攬人才、完成統(tǒng)一天下的雄心壯志。所以本單元安排《短歌行》一詩,對學生全面了解曹操,感受曹操在短暫的人生中竭力創(chuàng)造偉業(yè)的氣概。二、說學生我這一課的教學對象是高一學生。他們進入高中學習的時間只有三個多月,現(xiàn)在已經(jīng)完成了必修(一)的學習。學習了現(xiàn)代詩歌單元,有了一定的詩歌學習基礎(chǔ),初步掌握了讀詩的基本方法,但是還未能形成成熟的穩(wěn)定的學習方式。同時,本單元學習是高中第一次接觸古代詩歌,詩歌語言上的障礙和時間上的跨度對他們來說都是學習上的困難。因此教師要引導學生自主學習,合作學習,為他們設(shè)置新的學習情境,提供合作探究的機會。

1、教材的地位作用本課是新人教版普通高中歷史必修Ⅱ第六單元第18課的內(nèi)容,闡述羅斯福新政的背景、措施、影響。從單元知識安排看,本課與第17課《空前嚴重的資本主義世界經(jīng)濟危機》、19課《戰(zhàn)后資本主義的新變化》共同詮釋第六單元課題——《資本主義世界經(jīng)濟政策的調(diào)整》。說明了“資本主義經(jīng)濟理論和政策隨著資本主義發(fā)展而不斷調(diào)整的特點”,凸顯了“市場調(diào)節(jié)”和“國家干預”在經(jīng)濟發(fā)展中的重要性。從知識體系看,它是學生學習了第一次工業(yè)革命后自由資本主義、第二次工業(yè)革命后的壟斷資本主義等之后出現(xiàn)的,既是對上述知識的鞏固與綜合運用,又為學生學習必修二的相關(guān)內(nèi)容打下基礎(chǔ),有承上啟下的作用。本課三個子目從邏輯上看又是遞進關(guān)系。第一個子目“臨危受命”承上啟下,說明了羅斯福上臺的歷史背景具有臨危受命的特點,第二個子目“實施新政”講述了羅斯福新政的主要內(nèi)容,第三個子目“擺托危機困境”主要講述了羅斯福新政的影響。

Ⅲ. Analysis of the teaching material:The topic of this unit is cultural relics. Students are quite interested in topics about different cultures around the world. This is the second period of the whole unit.

(明確:“寡人之于國也,盡心焉耳矣”,但“寡人之民不加多,何也?”)②他認為自己對國家政務盡心盡力了,他有哪些具體做法?(明確:移民移粟)③第2—4節(jié)中孟子是怎樣說明梁惠王移民移粟的措施與“鄰國之政”并無本質(zhì)區(qū)別的?(明確:孟子不直接回答“民不加多”的問題,而是用梁惠王熟悉的“戰(zhàn)”設(shè)喻——設(shè)圈套,誘使對方在不知不覺中說出“不可,直不百步耳,是亦走也。”)④孟子認為怎樣才能做到“王道之始”?要想“王道之成”還需采取哪些措施?(明確:“不違農(nóng)時,谷不可勝食也。數(shù)罟不入氵夸池,魚鱉不可勝食也。斧斤以時入山林,材木不可勝用也。谷與魚鱉不可勝食,材木不可勝用五畝之宅,樹之以桑,五十者可以衣帛矣。雞豚狗彘之畜,無失其時,七十者可以食肉矣。百畝之田,勿奪其時,數(shù)口之家,可以無饑矣。謹庫序之教,申之以孝涕之義,頒白者不負戴于道路矣。)這一小步的目的是想讓學生通過這些問題的解答,可以進一步理清思路,掌握文的大概內(nèi)容。

3、重要語句的理解“可是一個人并不是生來要給打敗的,你盡可把它消滅掉,可就是打不敗他?!苯馕觯哼@是老人第一次回合之后的內(nèi)心獨白,也是此小說的核心精神,充分體現(xiàn)了老人桑地亞哥的生命理念。整句話可以分為兩部分來理解,前句告訴我們,人生活在自然與社會當中,必不可少要面臨一些坎坷、磨難,這些磨難、坎坷完全可以造成軀體的消滅、消亡,這是人生命的脆弱性。后句,面對挫折,只要保持一種樂觀的精神,擁有一顆堅強的心靈,那么,人類執(zhí)著奮斗的精神將永不磨滅。4、象征主義題目是《老人與?!?,而表明上,小說是寫一位老人及其在海上的經(jīng)歷,但實際上,老人的形象極具概括性,他已經(jīng)超越了一個人的存在,而成為了人生的一種象征。老人桑地亞哥就是“硬漢子”的代表,大海則是生命旅途的象征,鯊魚則是我們行走中的“強物”,厄運的象征。人的一生不可能一帆風順,不經(jīng)歷風雨,怎能見彩虹,走在人生路途中,不可避免我們都要遇到挫折,被厄運所阻撓,只有經(jīng)歷與“鯊魚”的較量,才能成為強者,唱出最美的歌。

在學生活動的基礎(chǔ)上,教師總結(jié)歸納:要堅持從群眾中來到群眾中去的工作方法。要求:政府要通過各種途徑,利用各種群眾組織、社會團體廣泛收集群眾意見和建議,認真對待群眾的來信來訪。還要為群眾誠心誠意辦實事,盡心竭力解難事,堅持不懈。通過合作探究,以此來培養(yǎng)學生的分析能力,探究能力以及透過現(xiàn)象看本質(zhì)的能力,培養(yǎng)學生獲取信息的能力,自主學習的能力以及全面看問題的能力,再結(jié)合教師的講授,給學生一種茅塞頓開的感覺。環(huán)節(jié)四 回歸生活 提升情感我將引導學生閱讀課本,通過設(shè)置活動探究課,結(jié)合生活實際從時效,便利,實效等方面請學生評述公民求助或投訴的四種方式的特點和優(yōu)點。在這一過程中,我還會用多媒體展示常用的熱線電話,政府網(wǎng)站上有關(guān)信訪、政務公開及其他便民利民的欄目,豐富課堂資源。讓學生閱讀課本,自行歸納知識點,有助于培養(yǎng)學生自主學習能力。
