3.明白最后一句話(huà)的含義,明白人一定要珍惜時(shí)間,積極爭(zhēng)取知識(shí)、能力、經(jīng)驗(yàn)的增長(zhǎng),不能錯(cuò)過(guò)時(shí)機(jī),否則就會(huì)成為一事無(wú)成的人。 三、說(shuō)教學(xué)重難點(diǎn)1.通過(guò)閱讀,理解為什么說(shuō)“夏天是萬(wàn)物迅速生長(zhǎng)的季節(jié)?!? 2.了解作者寫(xiě)作的順序,學(xué)習(xí)“圍繞中心句展開(kāi)描寫(xiě)”的方法。 3.體會(huì)作者的表達(dá)特點(diǎn),明白最后一句話(huà)的含義。四、說(shuō)教法學(xué)法 本課的教學(xué)我采用了創(chuàng)設(shè)情境法、朗讀感悟法、自主感悟合作交流法。首先從課文的題目入手,抓住題眼“成長(zhǎng)”思考:課文描寫(xiě)了夏天哪些事物的成長(zhǎng)?這些事物的成長(zhǎng)有什么特點(diǎn)?然后帶著問(wèn)題閱讀課文,并找出課文的中心句。再自讀課文,找出文中描寫(xiě)萬(wàn)物成長(zhǎng)的句子,讀一讀,體會(huì)萬(wàn)物在夏天成長(zhǎng)的特點(diǎn),學(xué)習(xí)圍繞中心句展開(kāi)具體描寫(xiě)的寫(xiě)作方法。最后聯(lián)系課文理解最后一句話(huà)的含義,從中受到啟示。

二、說(shuō)學(xué)情對(duì)于六年級(jí)的學(xué)生讀這篇文章時(shí),對(duì)于夏天里各種事物飛快地長(zhǎng),跳躍地長(zhǎng),理解起來(lái)比較容易,但是對(duì)于課文的最后一句話(huà)所蘊(yùn)含的道理學(xué)生理解起來(lái)有一定難度。 三、說(shuō)教學(xué)目標(biāo)和重點(diǎn)難點(diǎn) 在詳細(xì)解讀教材內(nèi)容的基礎(chǔ)上,依據(jù)課標(biāo)的要求和學(xué)生的實(shí)際情況,我將本課的教學(xué)目標(biāo)設(shè)定為:1.知識(shí)與技能目標(biāo):會(huì)寫(xiě)10個(gè)字。正確流利有感情地朗讀課文,理解課文主要內(nèi)容及重點(diǎn)句子的含義,體會(huì)作者的表達(dá)特點(diǎn)。2.過(guò)程與方法目標(biāo):通過(guò)學(xué)習(xí)理解和感悟,感受夏天里各種事物都在快速地生長(zhǎng)。學(xué)會(huì)與人交流,提高表達(dá)能力、學(xué)習(xí)語(yǔ)文的能力。3.情感態(tài)度與價(jià)值觀目標(biāo):讓學(xué)生體會(huì)“人也是一樣,要趕時(shí)候,趕熱天,盡量地用力地長(zhǎng)。”的含義,從而懂得把握時(shí)間珍惜時(shí)間。
