    統(tǒng)編版三年級語文上第27課一個粗瓷大碗教學(xué)設(shè)計教案

    《一個粗瓷大碗》是統(tǒng)編版教材三年級語文上冊第八單元的一篇略讀課文,本文圍繞“粗瓷大碗”講述了趙一曼把小通訊員盛給她的高粱米飯倒進(jìn)病號灶的鍋里,和戰(zhàn)士們一起喝野菜粥;把小通訊員給她找的用來吃飯的碗又一次丟掉了的故事,表現(xiàn)了她在艱苦的環(huán)境中關(guān)愛戰(zhàn)士勝過關(guān)心自己,與戰(zhàn)士同甘共苦、堅持革命的高貴品質(zhì)。課文是一篇略讀課文,學(xué)習(xí)時可帶著問題默讀,邊讀邊思考,這樣可以更好地理解課文的內(nèi)容。教學(xué)本文時,要由淺入深地設(shè)置問題,讓學(xué)生帶著問題默讀課文;還要提示學(xué)生,默讀時,沒讀懂的地方標(biāo)記下來,可以聯(lián)系上下文進(jìn)一步思考,也可以讀完之后和同學(xué)一起探討。 1.認(rèn)識“陳、曼”等7個生字,讀準(zhǔn)多音字“還”。2.能帶著問題默讀課文,了解圍繞“粗瓷大碗”發(fā)生的故事。3.能從人物的語言、動作等描寫中感受到人物的心情、品質(zhì)。 1.教學(xué)重點(diǎn):能帶著問題默讀課文,了解圍繞“粗瓷大碗”發(fā)生的故事。2.教學(xué)難點(diǎn):深入理解文章內(nèi)容,感受趙一曼的高貴品質(zhì)。 1課時

    十、教學(xué)后記:這是我實(shí)習(xí)中上的第一堂課,由于沒有經(jīng)驗,對時間的把握不好,課堂前半部分留給學(xué)生思考回答問題的時間太多了,以至于沒有完成本課時的教學(xué)內(nèi)容,對《箜篌引》、《桃花扇》、《聞官軍收河南河北》內(nèi)容的補(bǔ)充要留到下節(jié)課才能完成。但課堂過程中以討論和結(jié)果發(fā)布會的形式非常能調(diào)動學(xué)生的學(xué)習(xí)積極性,這節(jié)課學(xué)生的參與度很高,絕大部分的同學(xué)都能積極思考,并敢于回答問題。但是在學(xué)生回答問題后,有些答案很好,也是我沒有思考到的。但是除了簡單的表揚(yáng)鼓勵外,我不善于把學(xué)生的思考結(jié)果與自己的板書設(shè)計結(jié)合起來,授課過程中比較拘泥于教案,顯得不夠靈活。總的來說,這節(jié)課的優(yōu)點(diǎn)是教態(tài)自然、大方,聲音清晰洪亮,能調(diào)動學(xué)生學(xué)習(xí)的積極性,不足在于時間掌握不好,拘泥于教案。
