| 摘 要： | 分数意义的学习是小学数学学习的难点之一,其教学现实表明,学生的主要困难在于没有获得相应模式的帮助,而且教学结构单一、断裂。模式主导,双向多维的分数意义的教学结构,以模式为核心,双向多维、立体动态,使分数意义的教学更有效。其教学意义在于:数学化是数学学习的逻辑起点;数学学习过程是各路径双向互动、多路径融会贯通的有机整体。

| Abstract: | Fractional meaning learning is one of the difficult points in primary school mathematics learning,the main reason of which lies in students' lacking the assistance of the correspondent model and its teaching structure is single and discontinuous.The fractional meaning teaching structure characterized by model-orientation and dual directions with many dimensions would make teaching of fractional meaning much more efficient.Its teaching implications are as the follows:mathematization is the starting point of ... |
