    以單位量的方法處理小數的化聚與位值─以四年級為例
  • 著者: 邱月容; Chiu, Yueh-Jung

  • 主題: 單位量; 小數; 化聚與位值; units; decimal; conversion and place-value
  • 描述: 單位量的方法教學為利用具體物操作方式來進行小數教學。在本研究中，我們使用拼圖、尺、積木、吸管等進行有別於傳統方法之教學，來幫助學童加強小數化聚位值之學習，期望能減少學童在學習上的迷思，增進其學習成效。 本研究採準實驗研究法，研究對象以臺南市立崇明國小四年十班當作實驗班，進行由研究者設計的以單位量的方法處理小數的化聚與位值教學活動。另選取與實驗班差異最小的四年十一班作為對照組，進行一般傳統教學。研究以量化為主、質性為輔之分析，透過實驗教學後所得之測驗分數，進行獨立樣本t檢定的統計分析，從中探討學童在實驗教學後之學習成就表現，並另取實驗組之不同學習成就(高、中、低)學童各1名，分別進行半結構式訪談，探討學童學習概念改變情形。研究結果如下：一、以單位量的方法進行小數教學後，實驗班學生的後測結果優於對照班。二、學生於一個月後進行延後測結果，學習具有保留效果。三、以單位量的方法進行小數教學能夠讓學生更容易理解化聚與位值。
    Units teaching is the way of teaching decimal by concrete operation. In this research, we use puzzle, ruler, blocks, straw, as teaching aids which are different from traditional ways of teaching. This can help students to enforce learning of conversion and place-value of decimal, and to decrease the maze of learning and to be able to increase the effect of learning. The research is based on quasi-experimental research, with the 4th grade students in Tainan Municipal Chong-Ming elementary school. The experimental group is with units teaching for conversion and place-value of decimal, designed by researcher while the control group is with traditional teaching. The research outcome was analyzed through both the quality and the quantity method. By using the descriptive statistics and contingent T sample examing to analyze the assessing results, the researcher semi-structured interviewed one pupil from the lower, the middle and the higher level in order to look into pupils’ progress before and after the teaching. The results are as follows：1.The post-test results of the experimental group are better than the control group.2.The delay-test results of the experimental group have retention effects.3.Units teaching for decimal can help students understand more about the concept of conversion and place-value.
