三、辛亥革命的結局1.袁世凱竊取革命果實由課件給出竊取革命果實的簡單過程,幫學生理清思路,創(chuàng)設問題情境,由學生分析革命果實被竊取的原因,教師給以補充并揭示根本原因,貫穿整個革命的資產階級的軟弱性和妥協(xié)性,再次加深對難點的理解。2.歷史功績辛亥革命性質、功績由學生閱讀書本進行總結,再加以補充讓學生在書本上做好記錄,強調最大功績是結束了兩千多年的君主專制政體。辛亥革命的失敗及其評價很易搞成生硬的一言堂形式,可以從多種角度把學生思維調動起來。這里采用列舉一個合作探究,自由討論的題目“有人認為辛亥革命因為沒有完成反帝反封建的革命任務而失敗,有人則認為辛亥革命是中國“從君主到民主”社會轉型的成功開始。你同意哪種看法?”要求同學們自由討論.各抒己見,大膽創(chuàng)新,言之在理即可.教師在一旁引導學生,活躍課堂氣氛.最后教者歸納總結學習歷史從不同的角度看問題可以得出不同的結論,學會用辯證的觀點看待歷史問題,對辛亥革命有個全面的認識。

“第二次鴉片戰(zhàn)爭”爆發(fā)的原因的講析,可通過出示英國在鴉片戰(zhàn)爭后在中國與洪都拉斯的正當貿易對比表,讓學生觀察和創(chuàng)設情景來得出結論。戰(zhàn)爭的經過及影響,可以通過兩次鴉片戰(zhàn)爭形勢圖,以及一張相關的表格,從戰(zhàn)爭的根本目的、性質、過程及影響等方面來比較兩次戰(zhàn)爭的異同,從而讓學生理解掌握“戰(zhàn)火再燃”其實就是中英鴉片戰(zhàn)爭的繼續(xù)和擴大。并理解“第二次鴉片戰(zhàn)爭”的如何使中國社會半殖民地半封建化的程度大大加深了。并突出英法兩國殖民者在占領北京期間所犯的滔天罪行。3、結:結合板書設計,讓生自己總結這節(jié)課所學的內容,并通過課后習題練于講相結合,來鞏固本課知識。在此基礎上對本課線索及主要知識點進行簡要的梳理。4、課題延伸:教材后探究學習總結中的一段材料,即《英國駐華商務監(jiān)督義律致英國外交大臣巴麥尊的機密件》,讓學生究義律對中國發(fā)動鴉片戰(zhàn)爭原因的說辭來展開探討,啟發(fā)學生運用辨證唯物主義的基本觀點,澄清和批駁在在一問題上的一些錯誤和謬論,從而提高學生辨別是非的能力和批判的能力.

5.5癌癥的預防作為本節(jié)最重要內容,且與生活息息相關,我采用老師引導、學生討論總結的方法進行教學。從生活各方面總結出保健良方 ,既對知識有很好應用,又體現(xiàn)對生命的熱愛。此時,本節(jié)課達到高潮,同學們意氣風發(fā),熱烈討論,實現(xiàn)本節(jié)課的教學目標。5.6 癌癥的治療通過講述癌癥治療方法的副作用,激發(fā)學生探究生物學欲望,激勵學生立志除癌。 在此,我選用一則關于一名癌癥晚期病人運用心理療法成功戰(zhàn)勝癌癥的故事,在于對不同層次的學生進行多方面啟發(fā)教育,體現(xiàn)面向全體學生的課程理念。5.7 愉悅總結,及時反饋本節(jié)知識點零散,我將帶領學生回憶瀏覽本節(jié)內容,使零散知識點系統(tǒng)化。在課堂反饋環(huán)節(jié),我通過簡單練習采用分組競答的方式把握學生對知識的掌握程度,并給予表現(xiàn)突出的學生適當獎勵,這是本節(jié)課第三個亮點。競答既使課堂顯得緊湊、集中,又有利于形成學生的競爭意識,還使得學生的知識得以鞏固應用。

三、孟德爾遺傳規(guī)律的現(xiàn)代解釋①分離定律:在雜合體的細胞中,位于一對同源染色體上的等位基因,具有一定的獨立性;在減數(shù)分裂形成配子的過程中,等位基因隨同源染色體的分開而分離,獨立地隨配子遺傳給后代。②自由組合定律:位于非同源染色體上的非等位基因的分離或組合是互不干擾的;在減數(shù)分裂過程中,同源染色體的等位基因彼此分離的同時,非同源染色體上的非等位基因自由組合??偨Y:再次強調孟德爾遺傳定律的現(xiàn)代解釋課堂練習:書本31頁6、教學反思:本節(jié)課設置了一系列問題情境,層層設問,在學生答問、質疑、討論過程中讓學生建構新概念和新的知識體系,并通過教師及時掌握反饋信息,適時點撥、調節(jié),讓學生在推理判斷中培養(yǎng)良好的思維習慣和對知識的遷移能力,而且通過留出一定的時間讓學生提問,體現(xiàn)了以學生為主體的思想。

設問:DNA復制后兩個子代DNA分子與親代DNA分子是否完全相同?為什么?通過設問,讓學生進一步理解和鞏固DNA復制的全過程。接下來讓學生總結出DNA復制的四大基本條件:① 模板:開始解旋的DNA分子的兩條單鏈;② 原料:是游離在核液中的脫氧核苷酸;③ 能量:是通過水解ATP提供;④ 酶:酶是指一個酶系統(tǒng),不僅僅是指一種解旋酶。最后通過以上分析,總結出DNA復制的意義以及在生活中的應用:意義:DNA通過復制,使遺傳信息從親代傳給子代,從而保證了物種的相對穩(wěn)定性,保持了遺傳信息的連續(xù)性,使物種得以延續(xù)。應用:目前DNA分子廣泛應用于刑事案件偵破等方面:如:DNA分子是親子鑒定的主要證據(jù)之一。把案犯在現(xiàn)場留下的毛發(fā)、血等進行分析作為破案的證據(jù),與DNA有關。五、設計課堂練習:設計一題典型課堂練習:即有關半保留復制及計算的習題:

3、遺傳密碼的特點 連續(xù)性、簡并性、通用性5、課堂練習6、作業(yè)布置假如,我們利用(ACU)n核苷酸長鏈合成了含有蘇氨酸的多肽,那么蘇氨酸可能的密碼子有哪些?如何運用實驗方法確證蘇氨酸的密碼子究竟是什么?七、教學反思1、教材中豐富的科學史料,是我們在課堂上進行探究性學習活動的良好素材,教師要整理和運用好。千萬不要低估學生的思維能力,當學生的思維能力被你想方設法激發(fā)出來的時候,你會發(fā)現(xiàn)他們的創(chuàng)造力是無窮的。2、探究性學習的目的并不僅僅是問題的解決,更重要的是在探究過程中體驗和獲取科學研究方法,培養(yǎng)合作與分享的精神以及實事求是的科學態(tài)度,鍛煉思維能力,提高科學素養(yǎng)。3、學生是學習的主體,教師是引導者。我們要采取措施讓學生積極主動地參與到學習活動中來,通過他們的思考、討論、爭辯、合作等活動來獲取方法,建構知識。

四、說教學程序(一).溫故知新、導入新課復習提問:基因突變導致生物變異的原因是什么?回答:基因突變是基因結構發(fā)生改變,從而使遺傳信息改變,使蛋白質結構改變、生物性狀改變,即生物發(fā)生了變異。那么,基因是什么?它和染色體又有何關系?回答:基因是有遺傳效應的DNA片斷,染色體是DNA的載體,基因在染色體上呈線形排列。引出新知:對于一個生物體來說,正常情況下,其染色體的結構和數(shù)量都是穩(wěn)定的。但在自然條件或人為因素的影響下,染色體的結構和數(shù)量均會發(fā)生改變,從而導致生物性狀的改變,這就屬于染色體變異。(二).把握重點、突破難點重點的把握:1、染色體結構的變異播放影片:貓叫綜合征幼兒。讓學生觀察: 患兒哭聲輕、音調高,很像貓叫。教師補充: 患兒的征狀---兩眼較低、耳位低下,存在著嚴重的智力障礙。闡述病因---染色體片段缺失

第一部分:說教材我將從本框題的地位、教學目標及教學重難點等方面進行闡述。首先,本框題在教材知識體系中的地位:《影響價格的因素》是人教版教材高一政治必修第一單元第二課的第一框題。本框主要給學生介紹引起商品價格變化的因素,使學生通過學習能夠明確日常經濟生活中價格變動的原因。本框既是對前一課內容的承接又是下框內容得以展開的基礎,也就是說,本框在本單元學習中起著承上啟下的作用。其次,教學目標。根據(jù)課程標準的要求和學生的實際情況,我將確定以下的教學目標:(1)知識目標歸納影響價格的因素,理解價值決定價格、社會必要勞動時間決定價值量以及勞動生產率與商品價值量的關系,明確價值規(guī)律的基本內容和表現(xiàn)形式。(2)能力目標培養(yǎng)學生透過現(xiàn)象分析事物本質的能力;增強學生的競爭意識,提高參與經濟生活的能力。

l意義(這里突破難點的方式手段——舉典型例;結合時事;討論。演繹歸納法運用,引導學生對各種感性材料進行分析與歸納,形成一定的理性認識,做到理論與實際的緊密結合,提高學生的抽象思維能力。)接下來呢是課堂小結,引導學生根據(jù)板書鞏固知識。(這里我運用的是提綱式板書:這種形式的板書能夠突出課文的重點,便于學生抓住要領、把握內容、加深印象,培養(yǎng)學生的分析概括能力。)布置作業(yè):也就是教學評價環(huán)節(jié)引導學生課后搜集某個公司集團發(fā)展歷程,并做一定思考,下節(jié)課和大家交流。(這樣設計呢這樣設計旨在培養(yǎng)學生的實踐能力和動手操作能力,加深對知識的理解)謝謝大家,我的說課就到這里。懇請大家批評指正。板書設計:公司的經營一、公司的類型1、企業(yè)的含義2、公司的含義3、公司的類型:有限責任公司和股份有限公司

在學生明確了稅收的含義之后,我將分別對稅收的三個基本特征進行解析。在講解了之后,并分別用實例對其進行說明,加深學生對知識點的印象。最重要的是,總結出關鍵的字眼,使得學生能夠清晰的區(qū)分出稅收的三個基本特征。將強制性概括為依法征稅、依法納稅;無償性概括為不具有償還性和返還型;固定性概括為規(guī)定應不應納稅、納什么稅、納多少稅。并跟學生指出,強制性是基本前提,無償性是核心。由此根據(jù)書上的內容,推導出稅收的三個基本特征相互之間的關系,即:三者缺一不可,統(tǒng)一于稅法。而且,無償性要求強制性,強制性保障無償性;而無償性與強制性又共同決定固定性。從而結束新課講授。3、課堂總結根據(jù)板書內容重新回顧本課學習的主要內容,包括稅收的含義,以及稅收的三個基本特征和它們之間的相互關系。4、作業(yè)布置讓學生預習稅收的種類的內容,尤其是增值稅和個人所得稅。同時了解父母每月所繳納的個人所得稅和怎么計算的。

(三)課堂小結接著進行課堂小結,先讓學生自主總結,教師結合學生的總結,補充完善總結本節(jié)課的知識。并進行感情升華。這樣設計課堂小結,是為了讓學生學會自主總結知識,加深印象,教師總結幫助學生理清本課知識結構,并起到升華本節(jié)課的感情基調,落實教學目標。(四)課堂練習我將設計兩道題讓同學們做,鞏固課堂知識。本課題板書設計我主要采用大綱的形式展現(xiàn),讓學生一目了然,便于識記和理解主干知識。五、教學預測最后我對本節(jié)課教學的效果進行預測:在這個教學過程中我都是從學生生活中感知的現(xiàn)象入手,設計情境,預設學生的分析,學生的體驗,學生的感知,教師的點撥等。設計問題,學生自主合作探究,完成教學!通過這樣的學習我想一定會收到較好的教學效果,當然,在實際的教學中,肯定也會出現(xiàn)一些意想不到的情況,我還會根據(jù)教學過程中的動態(tài)變化,及時地調整和修改預設內容。

師:分析得非常到位。大家來看看薛寶釵是怎么說的?薛寶釵的評論:“不像吟月了,月字底下放一個‘色’字倒還使得,你看句句倒是月色。這也罷了,原來詩從胡說來,再遲幾天就好了。”生:(讀第三首詩)“精華欲掩料應難,影自娟娟魄自寒。一片砧敲千里白,半輪雞唱五更殘。綠蓑江上秋聞笛,紅袖樓頭夜倚欄。博得嫦娥應借問,緣何不使永團圓!”這首詩語言很樸實,但意境很深遠。我雖然讀過《紅樓夢》這本書,也看過電視劇,但我閱歷太淺,說不出詩中所包含的深刻內涵。師:賈寶玉的評論:“這首不但好,而且新巧有意趣,可知俗語說的‘天下無難事,只怕有心人。2.意識的形式是主觀的意識是人腦對客觀存在的反映,意識是不是僅僅是人腦對客觀存在原原本本的反映呢?“龍、鳳”是中華民族的象征,是炎黃子孫的兩大主要圖騰,但地球上從來就沒有出現(xiàn)過“龍、鳳”,那么“龍、鳳”的觀念又是從何而來的呢?原來,“龍、鳳”的觀念最早產生于原始社會的圖騰崇拜。、

1、課題引入:我設計以提問哲學到底是什么?的問題激發(fā)學生的閱讀興趣。我設計典型事例,通過學生討論,教師總結的形式,并得出其實哲學就在我們身邊。2、講授新課:(35分鐘)通過教材第一目的講解,讓學生明白,生活和學習中有許多蘊涵哲學道理的故事,表明哲學并不神秘總結并過渡:生活也離不開哲學,哲學可以是我正確看待自然、人生、和社會的發(fā)展,從而指導人們正確的認識和改造世界。整個過程將伴隨著多媒體影像資料和生生對話討論以提高學生的積極性。3、課堂反饋,知識遷移。最后對本科課進行小結,鞏固重點難點,將本課的哲學知識遷移到與生活相關的例子,實現(xiàn)對知識的升華以及學生的再次創(chuàng)新;可使學生更深刻地理解重點和難點,為下一框學習做好準備。

(3)一切從實際出發(fā)、實事求是在講授這部分內容時,同樣繼續(xù)利用長城的例子來說明,古人正是經過實地的考察得出最佳的建造地點等,結合了當?shù)禺敃r的實際來建造長城,引導學生得出從實際出發(fā),實事求是的結論。3、課程小結:本節(jié)的所有內容已經講授完畢了,為了讓學生更好地鞏固本節(jié)課所學的知識,我會利用板書為學生梳理本節(jié)的重點條框內容。這樣能夠幫助學生理清思路明確各知識點的關系。4、作業(yè):我會要求同學在課后以某一個事例(如:一件事情、一棟建筑、一輛汽車等)為例,來寫出著個事例中體現(xiàn)我們今天所講課的內容的知識點。七、說教學理念我的教學理念是以傳統(tǒng)的教授法與范例教學法就相結合的教學方法為主,充分利用多媒體的教學手段,結合事例來講解知識,在上課過程中充分調動同學的積極性來講解知識。我的說課完畢,不足之處望各位老師給予指正!

(二)組織學生探究知識并形成新的知識。我從學生的生活體驗入手,運用案例等形式創(chuàng)設情境呈現(xiàn)問題,使學生在自主探索、合作交流的過程中,發(fā)現(xiàn)問題、分析問題、解決問題,在問題的分析與解決中主動構建知識。主要通過幾幅漫畫讓學生思考其中的哲學道理,開始接觸哲學。漫畫一:種瓜得瓜,種豆得豆,種雞蛋得??漫畫二:甲:下雨好極啦!乙:下雨糟透了!漫畫三:——狂妄之徒,你竟然壞了祖上規(guī)矩!在引導學生思考、體驗問題的過程中,可以使學生逐步學會分析、解決問題的方法。這樣做既有利于發(fā)展學生的理解、分析、概括、想象等創(chuàng)新思維能力,又有利于學生表達、動手、協(xié)作等實踐能力的提高,促進學生全面發(fā)展,力求實現(xiàn)教學過程與教學結果并重,知識與能力并重的目標。

Good morning, distinguished judges:It’s my honor to talk about my teaching ideas with you. Today my topic is Women of Achievement. My presentation consists of six parts: the analysis of teaching material and student, teaching aims, key and difficult points, teaching and studying method, teaching procedures and blackboard design.First, let’s focus on the analysis of teaching material. This lesson is from New Senior English for China Student’s Book 4 Unit 1, the reading part. The main topic of the passage is the introduction of a student of Africanwildlife. After this lesson, the students will learn more information about her studying chimps in Africa, and their reading and speaking abilities can be developed as well.The next part is the analysis of students. My students are in senior high students. They have learnt English for many years, they’ve known many words and sentences, but their speaking and reading abilities are still not very good. So I will practice their speaking and reading abilities through different exercises.According to the New Standard Curriculum and the present situation, I set the teaching aims as follows: firstly, knowledge aims. Students can grasp some new words, such as worthwhile, move off. Moreover, students can understand the content of the passage and get familiar with the topic of studying chimps in wildlife. Secondly, ability aims. Students can use reading strategies such as skimming and scanning in reading process. Thirdly, emotional aims. Students can have the awareness of protecting animals and care about animals.Based on the above analysis, the key point of this lesson is to get the main idea and the detailed information from the passage; the difficult point is to talk about the wildlife protection and use reading strategies.
