几何直观是人脑对客观事物及其关系的一种直接识别或猜想的心理状态,也是一种思维方式,兼具形象思维、抽象思维两大特征。几何直观性常用于常规数学教学,能够有效培养学生运用图形语言进行交流的能力和空间想象能力,因此,加强几何直观与数学课程整合就显得十分重要。以初中数学教学为研究对象,以全等三角形和相似三角形数学知识点为实例阐明几何直观在初中数学教学中的实践应用,旨在言明几何直观性及几何直观思维在初中数学教学中的巨大作用。
Geometrical intuition is a kind of thinking mode which is a kind of thinking mode of direct cognition or conjecture of the human brain to the objective things and their relationship, which has the two characteristics of image thinking and abstract thinking. Geometric intuition is often used in regular mathematics teaching, which can effectively cultivate students’ ability to communicate in graphic language and spatial imagination ability. Therefore, it is very important to strengthen the integration of geometric intuition and mathematics curriculum. Taking the junior middle school mathematics teaching as the research object and the example of congruent triangle and similar triangle mathematics knowledge points, this paper illustrates the practical application of geometric intuition in the junior middle school mathematics teaching, aiming at demonstrating the great role of geometric intuition and geometric intuition in junior high school mathematics teaching .
