四、教學(xué)設(shè)計(jì)反思這節(jié)內(nèi)容是學(xué)生利用數(shù)形結(jié)合的思想去研究正比例函數(shù)的圖象，對(duì)函數(shù)與圖象的對(duì)應(yīng)關(guān)系有點(diǎn)陌生．在教學(xué)過(guò)程中教師應(yīng)通過(guò)情境創(chuàng)設(shè)激發(fā)學(xué)生的學(xué)習(xí)興趣，對(duì)函數(shù)與圖象的對(duì)應(yīng)關(guān)系應(yīng)讓學(xué)生動(dòng)手去實(shí)踐，去發(fā)現(xiàn)，對(duì)正比例函數(shù)的圖象是一條直線應(yīng)讓學(xué)生自己得出．在得出結(jié)論之后，讓學(xué)生能運(yùn)用“兩點(diǎn)確定一條直線”，很快作出正比例函數(shù)的圖象．在鞏固練習(xí)活動(dòng)中，鼓勵(lì)學(xué)生積極思考，提高學(xué)生解決實(shí)際問(wèn)題的能力．當(dāng)然，根據(jù)學(xué)生狀況，教學(xué)設(shè)計(jì)也應(yīng)做出相應(yīng)的調(diào)整。如第一環(huán)節(jié)：創(chuàng)設(shè)情境 引入課題，固然可以激發(fā)學(xué)生興趣，但也可能容易讓學(xué)生關(guān)注代數(shù)表達(dá)式的尋求，甚至對(duì)部分學(xué)生形成一定的認(rèn)知障礙，因此該環(huán)節(jié)也可以直接開(kāi)門見(jiàn)山，直入主題，如提出問(wèn)題：正比例函數(shù)的代數(shù)形式是y=kx，那么，一個(gè)正比例函數(shù)對(duì)應(yīng)的圖形具有什么特征呢？
