23、hang of教學反思陳葉錦本課是一節閱讀課， 通過一個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。故事生動有趣、引人入勝，容易激發學生的閱讀熱情。一準備階段經過內容的分析和研究， 發現這篇課文內容上還是比較簡單的， 學生應該比較容易理解， 但對于引力體重和態度的變化掌握起來有點困難， 所以在教學設計上特意運用了表格的形式來幫助學生理解在不同的情況下的變化。 那么整堂課的主線應該就顯得比較明確了。 當然在備課過程中， 對于課文的導入卻不知道該如何著手， 不知道應該怎么樣才能與課文鏈接起來， 很順利得讓學生能夠對這篇課文感興趣。于是進過一番資料的搜索，發現了一個有關于春暉中學太空授課的視頻，那么就可以很好地和課文進行一個銜接， 我想通過視頻效
