對(duì)農(nóng)村八年級(jí)學(xué)生理解二次根式的分析研究
發(fā)布時(shí)間:2019-02-25 13:41
【摘要】:二次根式是初中數(shù)學(xué)的重點(diǎn)內(nèi)容之一,也是難點(diǎn)之一。學(xué)習(xí)二次根式時(shí)已經(jīng)學(xué)習(xí)了平方根、算術(shù)平方根以及立方根等內(nèi)容。從形態(tài)表象看二次根式的定義實(shí)質(zhì)就是一個(gè)非負(fù)數(shù)的算術(shù)平方根,二次根式是“實(shí)數(shù)”的一部分,它是對(duì)“代數(shù)式”及“實(shí)數(shù)”等知識(shí)的補(bǔ)充和延伸,學(xué)習(xí)二次根式是為了更好的學(xué)習(xí)函數(shù)及代數(shù)式的相關(guān)內(nèi)容。本文通過(guò)對(duì)四川崇州153名農(nóng)村中學(xué)學(xué)生的問(wèn)卷調(diào)查和部分訪(fǎng)談,考察了八年級(jí)學(xué)生對(duì)二次根式定義的理解,性質(zhì)的理解和應(yīng)用。本文共五章,第一章主要說(shuō)明問(wèn)題的產(chǎn)生,以及研究本文的意義;第二章是根據(jù)現(xiàn)有的研究,從四個(gè)方面進(jìn)行概括,為本文后面的研究打下基礎(chǔ);第三章主要是通過(guò)對(duì)調(diào)查報(bào)告的分析得到學(xué)生對(duì)二次根式的掌握水平,并與學(xué)生交流得到相應(yīng)結(jié)論;第四章主要是結(jié)合前面的研究得到一些結(jié)論和教學(xué)建議;第五章是結(jié)合實(shí)際情況說(shuō)明研究存在的不足和以后的努力方向。
