    (六)說教學(xué)策略1.專題性海量的媒介信息必須加以選擇或者整合,以項目為依據(jù),進行信息篩選,形成專題性閱讀與交流;培養(yǎng)學(xué)生對文本信息“化零為整”的能力,提升跨媒介閱讀與交流學(xué)習(xí)的充實感。2.情境化情境教學(xué)應(yīng)指向?qū)W生的應(yīng)用,建構(gòu)富有符合時代氣息的內(nèi)容,與生活經(jīng)驗更加貼合,對學(xué)生的語言建構(gòu)與運用有所提升,在情境中能夠有效地進行交流。3.任務(wù)化以任務(wù)為導(dǎo)向的序列化學(xué)習(xí),可以為學(xué)生構(gòu)建學(xué)習(xí)路線圖、學(xué)習(xí)框架等具體任務(wù)引導(dǎo);或以跨媒介的認(rèn)識與應(yīng)用為任務(wù)的設(shè)置引導(dǎo);甚至以閱讀和交流作為序列化安排的實踐引導(dǎo)。4.整合性跨媒介閱讀與交流是結(jié)合線上線下的資源,形成新的“超媒介”,也能實現(xiàn)對信息進行“深加工”,多種媒介的信息整合只為一個核心教學(xué)內(nèi)容服務(wù)。5.互文性語言文字是語文之生命,我們是立足于語言文字的探討,音樂、圖像、視頻等文本與傳統(tǒng)語言文字文本形成互文,觸發(fā)學(xué)生對學(xué)習(xí)內(nèi)容立體化和具體化的感悟,提升學(xué)生的審美能力。

    北師大初中數(shù)學(xué)九年級上冊用配方法求解簡單的一元二次方程1教案

    探究點二:用配方法解二次項系數(shù)為1的一元二次方程用配方法解方程:x2+2x-1=0.解析:方程左邊不是一個完全平方式,需將左邊配方.解:移項,得x2+2x=1.配方,得x2+2x+(22)2=1+(22)2,即(x+1)2=2.開平方,得x+1=±2.解得x1=2-1,x2=-2-1.方法總結(jié):用配方法解一元二次方程時,應(yīng)按照步驟嚴(yán)格進行,以免出錯.配方添加時,記住方程左右兩邊同時加上一次項系數(shù)一半的平方.三、板書設(shè)計用配方法解簡單的一元二次方程:1.直接開平方法:形如(x+m)2=n(n≥0)用直接開平方法解.2.用配方法解一元二次方程的基本思路是將方程轉(zhuǎn)化為(x+m)2=n(n≥0)的形式,再用直接開平方法,便可求出它的根.3.用配方法解二次項系數(shù)為1的一元二次方程的一般步驟:(1)移項,把方程的常數(shù)項移到方程的右邊,使方程的左邊只含二次項和一次項;(2)配方,方程兩邊都加上一次項系數(shù)一半的平方,把原方程化為(x+m)2=n(n≥0)的形式;(3)用直接開平方法求出它的解.

    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.

    1. 這個寓言是一個關(guān)于一位國王古寓言。 The fable is an old fable about a king.2.作者用這個故事讓讀者對于社區(qū)的問題負(fù)有個人責(zé)任的必要印象深刻。The author used the story to impress upon readers with the need to take personal responsibility for problems in the community.3. 這個故事十分成功的實現(xiàn)了它的目的。The story was quite successful in achieving its purpose.Step 7 WritingPlease write a review of the story according the outline above.The fable is an old fable about a king who thought his people are lazy, so he put a large stone in the middle of the road and hides and waited to see if anyone will try to move it.The author used this story to impress upon readers with the need to take personal responsibility for problems in the community. 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. Use this checklist to help your partner revise his/her draft.1. Does the writer give a short description of the story ?2. Does the description include the most important details of the story ?3.
