一、充分感知,丰富表象,为形象思维积累素材形象思维是用表象来思维的,表象是形象思维的“细胞”。要发展形象思维必须打好基础,丰富表象的积累。1.动手操作,丰富表象动手操作,使学生各种感官都参与到学习中来,从多方面、多角度观察事物。例如:在学习几何形体时,首先要求学生动手制作和寻找一个或几个简单的实物模型。在进一步观察的同时开展摆、剪、画、比等活动,搞清几何图形各部分之间最突出的等量关系和特点,最后借助直观教具扩展到生活中去。
First, full of perception, rich appearance, accumulation of material image for the image of thinking Thinking is the use of appearance, appearance is the image of “cell ”. To develop the image of thinking we must lay a good foundation for enriching the appearance of accumulation. 1 hands-on operation, rich appearance hands-on operation, so that students are involved in all kinds of senses to learn, from many aspects, multi-perspective observation of things. For example: When learning geometry, first ask the students to create and find one or several simple physical models. In the course of further observation, we should carry out the activities of pendulum, shear, painting and ratio, and find out the most prominent equivalent relations and features among the various parts of the geometric figure. Finally, we expand it into our daily life with the aid of visual aids.
