“数”与“形”是一组对立体,又是一组统一体。数形结合是一种重要的数学思想方法,我们在数学教学中有意识地渗透和有效运用“数形结合”的策略,以解决实际问题的抽象性和复杂性。因此,我们需要将静态文字动态化,促进主动思辨;将理性文字感性化,促进主动生成。以此,使数量关系的精确刻画与空间形式的直观形象巧妙、和谐地结合,化繁为简,从而得到解决。
“Number ” and “Shape ” is a set of three-dimensional, but also a group of unity. Combination of numbers and shapes is an important method of mathematics and ideology. We consciously infiltrate and effectively use the strategy of “combination of numbers and figures” in mathematics teaching to solve the abstraction and complexity of practical problems. Therefore, we need to dynamicize static texts and promote proactive thinking; sensitize rational texts and promote proactive generation. In this way, the accurate portrayal of the quantitative relationship and the intuitive image of the spatial form are ingeniously and harmoniously combined and simplified, thus being resolved.
