    課堂上把重點放在了讓學生在讀的過程中體會出槐鄉(xiāng)孩子的懂事、吃苦耐勞和以苦為樂的特點,因為是略讀課文,所以我就只提了一個問題,槐鄉(xiāng)的孩子與我們有什么不同呢?讓學生通過各種方式的讀說自己讀了課文后的的體會。學生在回答時,大都抓住了“勤勞的槐鄉(xiāng)孩子是不向爸爸媽媽伸手要錢的,他們上學的錢是用槐米換來的.”及槐鄉(xiāng)孩子的勤勞,對此學生感受最深,槐鄉(xiāng)孩子以苦為樂的精神,是靠我點出來了,當時有部分學生說第三段寫的槐鄉(xiāng)孩子干活時的樣子寫得很好,當時天很熱他們還在干活.我就趁機引導學生朗讀體會當時天氣的熱,又讀一讀描寫干活時的句子,學生體會到孩子們勞動時是很快樂的。學生已經(jīng)能夠通過讀文理解文中的內(nèi)涵,但總結的能力不行,大都是只看到點,看不到面。反思本節(jié)課,雖然課文都是由學生具體讀,但都是我直接參與指導方法等,是我一步步引著走的,屬于半放半扶。下次的略讀課我打算完全放手,由各學習小組的組長和學生一起學習。

    圖形的全等教案教學設計

    教法分析:在新課程的教學中教師要向?qū)W生提供從事數(shù)學活動的機會,倡導讓學生親身經(jīng)歷數(shù)學知識的形成與應用過程,鼓勵學生自主探索與合作交流,讓學生在實踐中體驗、學習。因此,本節(jié)課我采用了多媒體輔助教學與學生動手操作、觀察、討論的方式,一方面能夠直觀、生動地反映各種圖形的特征,增加課堂的容量,吸引學生注意力,激發(fā)學生的學習興趣;另一方面也有利于突出重點、突破難點,更好地提高課堂效率。學法分析:初二年級學習對新事物比較敏感,通過新課程教學的實施,學生已具有一定探索學習與合作交流的習慣。但是一下子要學生從直觀的圖形去概括出抽象圖形全等的概念這是比較困難的。因此,我指導學生:一要善于觀察發(fā)現(xiàn);二要勇于探索、動手實驗;三要把自己的所思所想大膽地進行交流,從而得出正確的結論,并掌握知識。
