“数学视觉”一词,是前苏联心理学家佐拉夫列夫提出的,原意是指培养学生“不但能看到图形上引人注意的东西,而且也能看到一切并不在图形上的东西”的能力。在数学教学中有意识地加强学生数学视觉的训练,对于提高教学质量,具有重要意义。数学视觉具有下列特点:(一)广角性。学生感知数学信息(如图形、数字、符号、数量关系等)是从视觉开始的。我们常常发现,对于同一个信息源(如图形),每个学生获得的信息量是各不相同的。有的学生只看到事物的一部分 The term “mathematical vision” was proposed by the former Soviet psychologist Zolaflev. The original intention is to train students to “not only see the things that attract people’s attention on the graph, but also see everything that is not on the graph. ”Ability. In mathematics teaching, consciously enhancing students’ mathematical vision training is of great significance for improving teaching quality. Mathematical vision has the following characteristics: (a) wide-angle. Students perceive mathematical information (such as figures, numbers, symbols, quantity relations, etc.) to begin with the visual. We often find that the amount of information each student gets is different for the same information source (such as graphics). Some students only see a part of things
