摘要
一、目的和方法在数学教学中形与数、具体形象与抽象概念之间的关系问题是一个基本问题。这个问题在学生掌握几何知识中显得尤为突出。本研究的目的是考察小学儿童识别几何图形,初步掌握几何概念的心理特点和存在问题。小学生掌握几何知识,大体上包括以下几方面内容:识别简单的几何图形,掌握若干基本的几何形体的特征和概念,学会初步绘制简单几何图形的方法,逐步学会在复杂几何图形中识别简单几何图形,熟悉图形的变化与改组,学会求几种简单的几何形体的长度。
This study aims to discover the psychological peculiarities of how the primary school pupils recognize geome-trical figures,grasp geometrical concepts.This experiment shws that pupils'ability to recognize and draw geometri-cal figures is superior to the ability toexplain the peculiarities of geometricalfigures.The experiment proves that acertain psychological process is alwaysenvolved as we proceed from recognizingfigures to grasping common features offigures.
