23、of 教學(xué)反思陳葉錦本課是一節(jié)閱讀課，通過一個(gè)科幻小故事向我們說明了引力是如何變化的，以及在引力變化的情況下人體的重量是如何隨之改變的。故事生動(dòng)有趣、引人入勝，容易激發(fā)學(xué)生的閱讀熱情。一 準(zhǔn)備階段經(jīng)過內(nèi)容的分析和研究，發(fā)現(xiàn)這篇課文內(nèi)容上還是比較簡(jiǎn)單的，學(xué)生應(yīng)該比較容易理解，但對(duì)于引力體重和態(tài)度的變化掌握起來有點(diǎn)困難，所以在教學(xué)設(shè)計(jì)上特意運(yùn)用了表格的形式來幫助學(xué)生理解在不同的情況下的變化。那么整堂課的主線應(yīng)該就顯得比較明確了。當(dāng)然在備課過程中，對(duì)于課文的導(dǎo)入?yún)s不知道該如何著手，不知道應(yīng)該怎么樣才能與課文鏈接起來，很順利得讓學(xué)生能夠?qū)@篇課文感興趣。于是進(jìn)過一番資料的搜索，發(fā)現(xiàn)了一個(gè)有關(guān)于春暉中學(xué)太空授課的視頻，
