(三)合作交流能力提升教師:剛才我們通過實驗了解了小車的速度是怎樣隨時間變化的,但實驗中有一定的誤差,請同學們討論并說出可能存在哪些誤差,造成誤差的原因是什么?(每個實驗小組的同學之間進行熱烈的討論)學生:測量出現(xiàn)誤差。因為點間距離太小,測量長度時容易產生誤差。教師:如何減小這個誤差呢?學生:如果測量較長的距離,誤差應該小一些。教師:應該采取什么辦法?學生:應該取幾個點之間的距離作為一個測量長度。教師:好,這就是常用的取“計數(shù)點”的方法。我們應該在紙帶上每隔幾個計時點取作一個計數(shù)點,進行編號。分別標為:0、1、2、3……,測各計數(shù)點到“0”的距離。以減小測量誤差。教師:還有補充嗎?學生1:我在坐標系中描點畫的圖象只集中在坐標原定附近,兩條圖象沒有明顯的分開。學生2:描出的幾個點不嚴格的分布在一條直線上,還能畫直線嗎?
(二)初讀課文,整體感知首先教師對作者進行簡單介紹,再要求學生速讀課文,讓學生初步感知課文內容,歸納全文思路,邊讀邊思考PPT上的問題。問題:全文可以分成幾部分?此環(huán)節(jié)意在激發(fā)學生的學習主動性,培養(yǎng)學生的自學能力。讀畢,我會對學生的自學情況進行檢查反饋,鼓勵學生踴躍發(fā)言,說出自己理解的寫作思路,最后教師對學生的答案進行概括和總結,此環(huán)節(jié)能夠讓學生對中國建筑的特征整體把握,夯實學習本文的基礎,同時感知課文,理清文章脈絡,實現(xiàn)長文短教,為析讀本文作好鋪墊。(三)析讀課文,質疑問難此環(huán)節(jié)是教學的重要階段,在這里,我會以新課標為基準,做到閱讀指向每一個學生的個體閱讀,同時在教學過程中遵循啟發(fā)性,循序漸進性的原則。此環(huán)節(jié)運用小組合作學習法、討論法和問答法分析中國建筑的特征。同學每四人為一小組討論PPT上展示的問題。

【課件展示】《秦朝中央集權制度的建立》《教材簡析》《教學目標》《教法簡介》《教學過程設計及特色簡述》【師】本節(jié)內容以秦代政治體制和官僚系統(tǒng)的建立為核心內容,主要包括秦朝中央集權制的建立的背景、建立過程及影響。本節(jié)內容在整個單元中起到承前啟后的作用,在整個模塊中也有相當重要的地位。讓學生了解中國古代中央集權政治體制的初建對于理解我國古代政治制度的發(fā)展乃至我們今天的政治體制是十分必要的。 本堂課我采用多媒體和講授法及歷史辯論法相結合,通過巧妙設計問題情境,調動學生的學習積極性,使學生主動學習,探究思考。教師引導和組織學生采取小組討論、情景體驗等方式,達到教學目標。 本節(jié)內容分三個部分,下面首先看秦朝中央集權制度建立的前提即秦的統(tǒng)一
8、板書裝在套子里的人別里科夫的形象——有形的套子套己——無形的套子套人第二課時合作探究:目標挖掘主題及現(xiàn)實意義。問題設置,銜接上節(jié)課內容,層層深入。1、結合上節(jié)課別里科夫的形象分析:他的思想被什么套住,其悲劇原因在哪?(根據人物形象的分析與社會背景的了解,直擊主題。)沙皇腐朽的專制統(tǒng)治套住了他的思想,沙皇的清規(guī)戒律使他不敢越雷池一步,所以他是受害者,但他的身份性格以及特定的社會環(huán)境,又讓他成為沙皇統(tǒng)治的捍衛(wèi)者。2、他戀愛的情節(jié)以及科瓦連科這兩個人物的塑造的意義?(從人物以及主題入手,推翻沙皇的腐朽反動的統(tǒng)治,必須是每一個人都敢于打破套子,喚醒革新,更新觀念,拒絕腐朽。)別里科夫渴望打破束縛,也想革新,而科瓦連科兩個人物體現(xiàn)朝氣活潑,以及勇于打破常規(guī)束縛的勇氣,為革新升起了一片曙光。3、塑造別里科夫的手法,除了一般刻畫人物方法外,還有什么方法?
二、教學目標:1、知識與能力(1)了解我國古代冶金、制瓷、絲織業(yè)發(fā)展的基本情況;(2)了解中國古代手工業(yè)享譽世界的史實,培養(yǎng)學生的民族自信心。2、過程與方法(1)通過大量的歷史圖片,指導學生欣賞一些精湛的手工業(yè)藝術品,提高學生探究古代手工業(yè)的興趣;(2)運用歷史材料引導學生歸納古代手工業(yè)產品的基本特征。3、情感態(tài)度與價值觀:通過本課教學,使學生充分地感受到我國古代人民的聰明與才智,認識到古代許多手工業(yè)品具有較高的藝術價值,以及在世界上的領先地位和對世界文明的影響,增強民族自豪感。
巴金在十年浩劫中的大致經歷:放棄包弟并沒有換得保全一家人,1968年8月,巴金被關進牛棚改造,隨后經受了大字報、掛牌游街等形式的批斗。1970年,到農村改造,掏大糞、喂豬、背稻草、種地……1972年,妻子蕭珊在飽受精神折磨后患上癌癥,病逝。巴金的兒子在勞動改造的過程中也飽受精神和肉體上的折磨,性格變得內向抑郁,疾病纏身。此時,巴金69歲。巴金曾在《病中》一文寫道:“當姚文元拿著棒子的時候,我給關在牛棚里除了唯唯諾諾之外,敢于做過什么事情?十年間我不過是一條含著眼淚等人宰割的牛?!毙〗Y:(幻燈片12)社會是病態(tài)的社會,政治是高壓的政治,人性是扭曲的人性。十年文革,十年浩劫,給多少人留下了累累不可彌合的精神創(chuàng)傷。即使一條小狗,也可能擺脫不了“文革”無情的迫害,比如包弟,比如藝術家鄰居的小狗。
一般情況下,凡是支持物對物體的支持力,都是支持物因發(fā)生形變而對物體產生彈力。所以支持力的方向總是垂直于支持面而指向被支持的物體。例1:放在水平桌面上的書書由于重力的作用而壓迫桌面,使書和桌面同時發(fā)生微小形變,要恢復原狀,對桌面產生垂直于桌面向下的彈力f1,這就是書對桌面的壓力;桌面由于發(fā)生微小的形變,對書產生垂直于書面向上的彈力f2,這就是桌面對書的支持力。學生分析:靜止地放在傾斜木板上的書,書對木板的壓力和木板對書的支持力。并畫出力的示意圖。結論:壓力、支持力都是彈力。壓力的方向總是垂直于支持面而指向被壓的物體,支持力的方向總是垂直于支持面而指向被支持的物體。引導學生分析靜止時,懸繩對重物的拉力及方向。引導得出:懸掛物由于重力的作用而拉緊懸繩,使重物、懸繩同時發(fā)生微小的形變。重物由于發(fā)生微小的形變,對懸繩產生豎直向下的彈力f1,這是物對繩的拉力;懸繩由于發(fā)生微小形變,對物產生豎直向上的彈力f2,這就是繩對物體的拉力。
l.知識與技能:(1)知道摩擦力產生的條件。(2)能在簡單問題中,根據物體的運動狀態(tài),判斷靜摩擦力的有無、大小和方向;知道存在著最大靜摩擦力。(3)掌握動磨擦因數(shù),會在具體問題中計算滑動磨擦力,掌握判定摩擦力方向的方法。(4)知道影響到摩擦因數(shù)的因素。2.過程與方法:通過觀察演示實驗,概括出摩擦力產生的條件及摩擦力的特點,培養(yǎng)學生的觀察、概括能力。通過靜摩擦力與滑動摩擦力的區(qū)別對比,培養(yǎng)學生分析綜合能力。3.情感態(tài)度價值觀:在分析物體所受摩擦力時,突出主要矛盾,忽略次要因素及無關因素,總結出摩擦力產生的條件和規(guī)律。二、重點、難點分析1.本節(jié)課的內容分滑動摩擦力和靜摩擦力兩部分。重點是摩擦力產生的條件、特性和規(guī)律,通過演示實驗得出關系f=μN。2.難點是學生有初中的知識,往往誤認為壓力N的大小總是跟滑動物體所受的重力相等,因此必須指出只有當兩物體的接觸面垂直,物體在水平拉力作用下,沿水平面滑動時,壓力N的大小才跟物體所受的重力相等。
