一、創(chuàng)設(shè)情境，設(shè)置懸念，激趣導(dǎo)入。好的開端是一堂課成功的一半。正因為如此，我運用激趣導(dǎo)入，進行猜謎語、聽聲音比賽。利用課件引導(dǎo)學(xué)生的聽覺、視覺、思維想象多渠道運作起來，積極參與到學(xué)習(xí)中。而且我還特別設(shè)計了個別聲音用耳朵比較難以辨別，學(xué)生只好用眼睛揭開謎底，從而初步接觸課文“眼見為實”的主旨。最后出示“咕咚”的聲音，讓學(xué)生猜猜這樣的聲音通常在什么情況下會出現(xiàn)，激發(fā)他們的想象力。讓學(xué)生模擬發(fā)“咕咚”聲，從而引出課題。并且告訴大家：千萬別小看這個有點奇怪的聲音，它可在森林中掀起了一場不大不小的風(fēng)波呢。
部編人教版一年級下冊《夜色》說課稿

部編人教版一年級下冊《靜夜思》說課稿
一、 說教材《靜夜思》是一年級下冊第四單元第7課的一篇李白的古詩，他的詩想象豐富，風(fēng)格飄逸豪放?！鹅o夜思》寫的是游子月夜思鄉(xiāng)之情。作者以一個游子的身份神馳萬里，從“疑”到“舉頭”，從“舉頭”到“低頭”，形象地表現(xiàn)了詩人的心理活動過程，一幅鮮明的月夜思鄉(xiāng)圖生動地呈現(xiàn)在我們面前，表達了游子強烈的思鄉(xiāng)情感。這首詩語言凝練，感情真摯，意境深遠(yuǎn)，容易引起讀者的共鳴。二、 說學(xué)情這首詩通俗易懂，家喻戶曉，有的學(xué)生在入學(xué)之前已經(jīng)倒背如流。但是多數(shù)學(xué)生在朗讀古詩的韻味上缺乏鍛煉。所以教學(xué)本詩，應(yīng)重在吟誦，指導(dǎo)學(xué)生讀準(zhǔn)字音，讀出節(jié)奏，激發(fā)學(xué)習(xí)古詩的興趣，引導(dǎo)學(xué)生在讀中感悟詩中綿綿的思鄉(xiāng)之情，體會詩歌的韻味和美好的意境。
