    人教版高中政治必修4生活處處有哲學(xué)說課稿

    (二)組織學(xué)生探究知識并形成新的知識。我從學(xué)生的生活體驗入手,運用案例等形式創(chuàng)設(shè)情境呈現(xiàn)問題,使學(xué)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(gòu)建知識。主要通過幾幅漫畫讓學(xué)生思考其中的哲學(xué)道理,開始接觸哲學(xué)。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(dǎo)學(xué)生思考、體驗問題的過程中,可以使學(xué)生逐步學(xué)會分析、解決問題的方法。這樣做既有利于發(fā)展學(xué)生的理解、分析、概括、想象等創(chuàng)新思維能力,又有利于學(xué)生表達、動手、協(xié)作等實踐能力的提高,促進學(xué)生全面發(fā)展,力求實現(xiàn)教學(xué)過程與教學(xué)結(jié)果并重,知識與能力并重的目標(biāo)。

    f.有絲分裂的意義(討論分析教學(xué)),首先引導(dǎo)學(xué)生結(jié)合所學(xué)知識討論有絲分裂的的作用,最后有教師歸納總結(jié),并要求學(xué)生在理解的基礎(chǔ)上記憶。g.無絲分裂(圖形直觀教學(xué)、簡介),本部分內(nèi)容不是教學(xué)的重點,內(nèi)容也相對簡單,所以我的教學(xué)方法是直接給學(xué)生展示掛圖,再進行簡短介紹,讓學(xué)生了解即可。h.引出減數(shù)分裂的概念,為第五章學(xué)習(xí)打下基礎(chǔ)。小結(jié):新課講完以后由教師對本節(jié)內(nèi)容進行總結(jié)鞏固和反饋:進行一些課堂練習(xí)達到鞏固和反饋的作用。最后布置作業(yè),各種難度的作業(yè)題目均設(shè)置一些,其中簡單題比重大,難題要求學(xué)生選作,這樣提高學(xué)生學(xué)習(xí)積極性。2教學(xué)媒體程序設(shè)計: 細(xì)胞周期的概念(多媒體課件演示周期動畫)植物細(xì)胞有絲分裂(多媒體課件演示分裂各期動畫)動植物細(xì)胞有絲分裂異同點(多媒體課件演示分裂各期動畫)有絲分裂過程中DNA和染色體數(shù)量的變化規(guī)律(掛圖演示,包括表格和函數(shù)圖象)

    一、對教材內(nèi)容的處理根據(jù)新課程標(biāo)準(zhǔn)的要求、知識的跨度、學(xué)生的認(rèn)知水平,我對教材內(nèi)容有增有減。二、教學(xué)策略的選用(一)運用了模擬活動,強化學(xué)生的生活體驗,本框題知識所對應(yīng)的經(jīng)濟現(xiàn)象,學(xué)生已具有了一定的生活體驗,但是缺乏對這種體驗的深入思考。因此在進一步強化這種體驗的過程中進行了思考和認(rèn)知,使知識從學(xué)生的生活體驗中來,從學(xué)生的思考探究中來,有助于提高學(xué)生的興趣,有助于充分調(diào)動學(xué)生現(xiàn)有的知識,培養(yǎng)學(xué)生的各種能力,也有助于實現(xiàn)理論知識與實際生活的交融。(二)組織學(xué)生探究知識并形成新的知識我從學(xué)生的生活體驗入手,運用案例等形式創(chuàng)設(shè)情境呈現(xiàn)問題,使學(xué)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(gòu)建知識。也正是由于這些認(rèn)識來自于學(xué)生自身的體驗,因此學(xué)生不僅“懂”了,而且“信”了。從內(nèi)心上認(rèn)同這些觀點,進而能夠主動地內(nèi)化為自己的情感、態(tài)度、價值觀,并融入到實踐活動中去,有助于實現(xiàn)知、行、信的統(tǒng)一。

    4、課堂討論:社會主義的根本原則是共同富裕,這也是正確處理分配關(guān)系的目標(biāo)。而十五大報告卻進一步明確指出“允許和鼓勵一部分人通過誠實勞動和合法經(jīng)營先富起來,允許和鼓勵資本、技術(shù)等生產(chǎn)要素參與收益分配”。這矛盾嗎?為什么?以小組方式進行討論,再以代表的形式發(fā)表意見,這樣既調(diào)動了學(xué)生的積極性,也使學(xué)生對內(nèi)容有了更深層次的了解。最后老師加以總結(jié),用“蛋糕效應(yīng)”來闡述“效率優(yōu)先,兼顧公平”的關(guān)系,既形象又貼切,加深學(xué)生的理解。本課時內(nèi)容比較抽象,學(xué)生對于概念的理解有較大的難度。因此在教學(xué)中我采用多媒體課件教學(xué),聯(lián)系生活實際,讓學(xué)生在生活中去體會貨幣的職責(zé),區(qū)分貨幣的職能,以便達到學(xué)以致用的目的。同時適時設(shè)置疑問,讓學(xué)生與我共同思考,真正實現(xiàn)“師生互動,生生互動”,調(diào)動學(xué)生積極,主動的參與到教學(xué)實踐活動中。(三)課堂小結(jié),強化認(rèn)識。(2—3分鐘)通過歸納小結(jié),既強調(diào)了重點,又鞏固了本節(jié)知識,幫助學(xué)生形成知識網(wǎng)絡(luò),便于課后理解記憶。

    Example:One day, a poor boy who was trying to pay his way through school by sending newspapers door to door found that he only had one dime(一角)left. He was so hungry that he decided to beg for a meal at the next house.However, he lost his nerve when a lovely young woman opened the door. Instead of a meal he asked for a drink of water. She thought he looked hungry so she brought him a large glass of milk. He drank it slowly, and then asked, “How much do I owe you?” “You don’t owe me anything,” she replied, “Mother has taught me never to accept pay for a kindness.” “Then I thank you from the bottom of my heart.” With these words, Howard Kelly left that house.Years later the woman became badly ill and was finally sent to the hospital in a big city. Dr. Howard Kelly, now famous, was called in. When he heard the name of the town she came from, a strange light filled his eyes. Dressed in his doctor’s clothes, Dr. Kelly went into her room and recognized her at once. From that day on, he gave special attention to her, and decided to do his best to save her life.At last the woman was saved. Dr. Kelly asked the business office to pass the final bill to him. He looked at it and then wrote something on the side. The bill was sent to the woman’s room. She was afraid to open it because she was sure that it would take the rest of her life to pay for it off. Finally she looked, and the note on the side of the bill caught her attention. She read these words: “Paid in full with a glass of milk, Dr. Howard Kelly.” Tear of joy flooded her eyes.

The story was quite successful in achieving its purpose, and I liked it because it had a clear moral.However, while the moral of the story is clear, the actions of the king seemed pointless to me, because none of the characters in the story learnt anything. For this reason, I think there are better stories that can be used to impress upon people with the need for personal responsibility.Step 8 Pair workExchange drafts with a partner.

    人教版新課標(biāo)高中物理必修2萬有引力定律說課稿2篇

    學(xué)生中存在這樣的問題:既然宇宙間的一切物體都是相互吸引的,那么為什么沒有吸引到一起?為了解決這個問題,安排了例題2例2、兩物體質(zhì)量都是1kg,相距1m,它們間的萬有引力是多少?通過本題,讓學(xué)生認(rèn)識到一般物體間的引力極小,不用考慮。那么,質(zhì)量很大的天體為什么沒被吸引到一塊?從而引出下節(jié)課題。4.課堂小結(jié):本節(jié)課,從天體運動出發(fā),通過推理證明,形成理性認(rèn)識,再結(jié)合例題習(xí)題使學(xué)生的理性認(rèn)識再反饋到具體事實。形成實踐-理論-實踐的認(rèn)知循環(huán),順應(yīng)了認(rèn)知規(guī)律.。本共設(shè)計了很多問,能讓學(xué)生想的盡量讓學(xué)生想、能學(xué)生說的盡量讓學(xué)生說、能讓學(xué)生做的盡量讓學(xué)生做,全面發(fā)展學(xué)生的各方面能力。再通過作業(yè)和探究性課題使學(xué)生的思維活動在時空上得以延續(xù)。5.布置作業(yè):布置作業(yè)時刻意安排引入:萬有引力、重力、向心力、三者的聯(lián)系,通過引導(dǎo)學(xué)生對比結(jié)果,從中發(fā)現(xiàn)問題:萬有引力與重力向心力的關(guān)系與區(qū)別,為下節(jié)知識的難點突破作好了鋪墊。

    人教版新課標(biāo)高中物理必修2追尋守恒量—能量說課稿2篇

    [小結(jié)]師:下面同學(xué)們概括總結(jié)本節(jié)所學(xué)的內(nèi)容。請一個同學(xué)到黑板上總結(jié),其他同學(xué)在筆記本上總結(jié),然后請同學(xué)評價黑板上的小結(jié)內(nèi)容。 (學(xué)生認(rèn)真總結(jié)概括本節(jié)內(nèi)容,并把自己這節(jié)課的體會寫下來、比較黑板上的小結(jié)和自己的小結(jié),看誰的更好,好在什么地方。) 生:本節(jié)課我們通過伽利略理想斜面實驗,分析得出了能量以及動能和勢能的概念,從能量的相互轉(zhuǎn)化角度認(rèn)識到,在動能和勢能的相互轉(zhuǎn)化過程中,能的總量保持不變,即能量是守恒的。通過這節(jié)課的學(xué)習(xí),使我們建立起了守恒的思想。 點評:總結(jié)課堂內(nèi)容,培養(yǎng)學(xué)生概括總結(jié)能力。 教師要放開,讓學(xué)生自己總結(jié)所學(xué)內(nèi)容,允許內(nèi)容的順序不同,從而構(gòu)建他們自己的知識框架。[布置作業(yè)]課后討論 P3“問題與練習(xí)”中的問題。[課外訓(xùn)練]以豎直上拋的小球為例說明小球的勢能和動能的轉(zhuǎn)化情況。在這個例子中是否存在著能的總量保持不變?
