心理学指出,7~14岁的儿童正处于从具体形象思维为主要形式向抽象思维为主要形式的过渡阶段。在小学数学教学中,如果把培养学生的形象思维能力和抽象思维能力结合起来,是两种思维相互促进,和谐发展,就能促进学生的思维能力的发展和过渡,从而培养学生良好的思维品质。从数学的学科特点上看,数学是研究客观数量关系和空间形式的科学。数量关系和空间形式在数学中相互渗透,相互转 Psychology pointed out that children aged 7 to 14 are in the transitional stage from the concrete form of thinking as the main form to the abstract form of thinking as the main form. In the elementary mathematics teaching, if the combination of cultivating students’ ability of image thinking and abstract thinking is the promotion and harmonious development of two kinds of thinking, it can promote the development and transition of students’ thinking ability so as to cultivate students’ good thinking quality . From the mathematical characteristics of mathematics point of view, mathematics is to study the relationship between objective and quantitative and spatial form of science. Quantitative relations and spatial forms interpenetrate each other in mathematics
