几何直观是2011版义务教育数学课程标准提出的十个核心概念之一。小学生的思维特点决定了他们在理解抽象概念、进行逻辑思维时,需要借助几何直观。本文针对调查研究发现的问题,从教学的角度提出了培养小学生几何直观能力的策略:第一建立数与形的联系;第二借助图形描述问题;第三利用图形揭示数量关系,感悟数学思想。
Geometrical intuition is one of the ten core concepts put forward by the 2011 compulsory education mathematics curriculum standard. Thinking characteristics of primary school students decided that they need to use geometric intuition in understanding abstract concepts, logical thinking. According to the problems found in the investigation and research, this paper puts forward strategies to cultivate pupils’ geometric intuitionistic ability from the perspective of teaching: the first establishes the connection between numbers and shapes; the second uses graphics to describe the problems; the third uses figures to reveal the quantitative relations and comprehends mathematics thoughts.
