反比例函數(shù)教案教學(xué)設(shè)計(jì)
本節(jié)的內(nèi)容主要是反比例函數(shù)的概念教學(xué).反比例函數(shù)概念的建立，不能從形式上進(jìn)行簡(jiǎn)單的抽象與概括，而是對(duì)這些實(shí)例從不同角度抽象出本質(zhì)屬性后，再進(jìn)行概括。教材設(shè)計(jì)的基本思路是從現(xiàn)實(shí)生活中大量的反比例關(guān)系中抽象出反比例函數(shù)概念，讓學(xué)生進(jìn)一步感受函數(shù)是反映現(xiàn)實(shí)世界中變量關(guān)系的一種有效數(shù)學(xué)模型，逐步從對(duì)具體反比例函數(shù)的感性認(rèn)識(shí)上升到對(duì)抽象的反比例函數(shù)概念的理性認(rèn)識(shí). 同時(shí)本節(jié)的學(xué)習(xí)內(nèi)容，直接關(guān)系到本章后續(xù)內(nèi)容的學(xué)習(xí)，也是繼續(xù)學(xué)習(xí)其它各類(lèi)函數(shù)的基礎(chǔ)，其中蘊(yùn)涵的類(lèi)比、歸納、對(duì)應(yīng)和函數(shù)的數(shù)學(xué)思想方法，對(duì)學(xué)生今后研究問(wèn)題、解決問(wèn)題以及終身的發(fā)展都是非常有益的.基于以上分析，本節(jié)教學(xué)設(shè)計(jì)是建立在一個(gè)個(gè)數(shù)學(xué)活動(dòng)的基礎(chǔ)上，經(jīng)過(guò)對(duì)情境理解、本質(zhì)抽象的積累而形成的.讓學(xué)生對(duì)一類(lèi)問(wèn)題情境中兩個(gè)變量間的關(guān)系，在充分經(jīng)歷寫(xiě)表達(dá)式，計(jì)算函數(shù)值和觀察函數(shù)值隨自變量變化規(guī)律的過(guò)程中，逐步概括形成反比例函數(shù)的概念.針對(duì)教學(xué)實(shí)際，我選取了貼學(xué)生現(xiàn)實(shí)的，有價(jià)值的實(shí)例“文具店里買(mǎi)學(xué)習(xí)用品”和“剪面積為定值的長(zhǎng)方形紙片”等作為問(wèn)題情境.

一次函數(shù)教學(xué)教案
教學(xué)目標(biāo)1.能從實(shí)際問(wèn)題中得到函數(shù)關(guān)系式，學(xué)會(huì)積累函數(shù)的建模思想；2.能對(duì)不同背景下函數(shù)模型（關(guān)系式）的比較，抽象出一次函數(shù)和正比例函數(shù)的概念，發(fā)展抽象思維及概括能力；3.初步理解一次函數(shù)與正比例函數(shù)的概念；4.知道一次函數(shù)與正比例函數(shù)的聯(lián)系和區(qū)別，體驗(yàn)特殊和一般的辯證關(guān)系；5.會(huì)判斷兩個(gè)變量之間的關(guān)系是一次函數(shù)還是正比例函數(shù)；6.能根據(jù)問(wèn)題信息，確定一次函數(shù)與正比例函數(shù)的表達(dá)式，提升數(shù)學(xué)應(yīng)用能力；7.會(huì)根據(jù)一次函數(shù)與正比例函數(shù)的概念，求字母的取值；8.在一次函數(shù)和正比例函數(shù)概念的形成與應(yīng)用過(guò)程中, 體驗(yàn)函數(shù)與人類(lèi)生活的密切聯(lián)系，增強(qiáng)對(duì)函數(shù)學(xué)習(xí)的求知。感受合作交流的必要性，同時(shí)提高學(xué)生的觀察、抽象、概括的能力和語(yǔ)言表達(dá)能力，從而培養(yǎng)學(xué)生對(duì)學(xué)習(xí)數(shù)學(xué)的興趣。
