於 2018年9月5日 (三) 04:18 的修訂

  • 本站提供一些英文輔助教材,主要是單字練習和單句練習,幫助台灣的小學4,5,6年級的學生更有效地使用英文版的 KhanAcademy 數學內容,作為學習英文的另一種途徑。本站用 Quizlet 幫助學生自主學習英文單字和單句,並且用 Kahoot 的趣味競賽或合作方式幫助學生共學英文單字和單句。
  • 小學4,5,6年級的學生,用英文版的 KhanAcademy 幼教和小學低年級的數學內容來學習英文時,不會有數學及英文的雙重困難;因為那些數學觀念在學校的小學低年級的數學課中早已熟悉,或中高年級正在學習,且幾乎天天在數學學習的環境中不斷使用。
  • 這些簡單又每天都繼續在學習中使用的數學觀念,成為英文初學者入門學習英文的大好基礎和機會。
  • 當學生日復一日地熟悉本站所提供的輔助教材時,就可以漸近地理解英文版 KhanAcademy 的教學影片所要教導的數學觀念的英文表達方式。
  • 接下來,學生從做英文版的 KhanAcademy 練習題的解題過程中,反覆應用所學到的英文來回答類似題型的許多題目,並且即時獲得電腦的回饋,立刻得知自己是否能够用英文來理解題意。
  • 這樣,讓學生能體驗到剛剛所學到的英文單字可以立刻學以致用解決問題,以利觸發並支持學習英文的動機和興趣。
  • 此外,藉著不斷的在解題中應用所學到的英文,在來達到深刻理解英文和長期記憶的效果。
