| 中文摘要 | 本研究探討一位具有小數大小比較之分數規則迷思概念的個案,在透過電算器,接受小數概念的教學活動後,分敗規則迷思概念改善的情形,以瞭解電算器教學活動是否能促進學童小數大小比夜概念的發展。研究方法是採半結構式晤談法,訪談的對象是一位國小六年級的學生。教學方法是採「累加」、「歸零」、「×10或÷10」的電算器活動,進行小數「單位量」、「位值關係」、「多單位」概念的教學。研究證實,上述的教學活動確實能克服學童的之迷思概念。 |
| 英文摘要 | This study was to explore the effects of using calculator in learning decimal numbers. The subject of this study was a sixth grader who had misconception of 「fraction rule」 in comparing the largeness of decimal numbers.
