在第1環(huán)節(jié)基礎(chǔ)上,再讓同學(xué)認(rèn)識到函數(shù)Y=2X-1的圖象與方程2X-Y=1的對應(yīng)關(guān)系,從而把兩個方程組成方程組,讓學(xué)生在理解二元一次方程與函數(shù)對應(yīng)的基礎(chǔ)上認(rèn)識到方程組的解與交點坐標(biāo)的對應(yīng)關(guān)系,從而引出二元一次方程組的圖象解法。3、例題訓(xùn)練,知識系統(tǒng)化通過書上的例1,用作圖象的方法解方程組,讓學(xué)生明白解題步驟與格式,從而規(guī)范理順?biāo)鶎W(xué)的圖象法解方程組,例題由師生合作完成,由學(xué)生說老師寫的方式。4、操作演練、形成技能讓學(xué)生獨立完成書P208隨堂練習(xí),給定時間,等多數(shù)學(xué)生完成后,實物投影其完成情況,并作出分析與評價。5、變式訓(xùn)練,延伸擴(kuò)展通過讓學(xué)生做收上P208的試一試,而后給一定時間相互交流,并請代表發(fā)言他的所悟,然而老師歸納總結(jié),并讓學(xué)生通過自已嘗試與老師的點拔從“數(shù)”與“形”兩個方面初步體會某些方程組的無解性,進(jìn)一步發(fā)展學(xué)生數(shù)形結(jié)合的意識和能力。6、檢測評價,課題作業(yè)
說明:此處進(jìn)行的是一次嘗試應(yīng)用乘方運算來解決開頭的問題,互相呼應(yīng),以體現(xiàn)整節(jié)課的完整性,把學(xué)生開始的興趣再次引向高潮。趣味探索:一張薄薄的紙對折56次后有多厚?試驗一下你能折這么厚嗎?說明:這個探索實際上仍是對學(xué)生應(yīng)用能力的一個檢查,紙對折56次,用什么運算來計算比較方便,另外計算過程中可使用計算器,進(jìn)一步加深對乘方意義的理解(五)作業(yè)P56頁1、2說明:這兩個習(xí)題是對課本上例題的簡單重復(fù)和模仿,通過本節(jié)課的學(xué)習(xí),多數(shù)學(xué)生應(yīng)該可以較輕松地完成。總之,在整個教學(xué)設(shè)計中,我始終以學(xué)生為課堂主體,讓他們積極參與到教學(xué)中來,不斷從舊知識中獲得新的認(rèn)識,通過不斷進(jìn)行聯(lián)系比較,讓學(xué)生主動自覺地去思考、探索、總結(jié)直至發(fā)現(xiàn)結(jié)果、發(fā)現(xiàn)"方法",進(jìn)而優(yōu)化了整個教學(xué)。
