想象,是在原有感性形象的基础上制造出新形象的心理过程。在数学教学中,想象力是学生在数学王国中自由翱翔的双翅,不仅在立体几何的学习中,需要有高度的空间想象力,而且在所有数学分支的学习中,丰富的想象力都是不可缺少的。一、想象的种类根据想象有无目的性与意识性,可分为有意想象与无意想象。有意想象根据在新颖性与独创性方面的差异,又可分为再造想象与创造想象。下面着重介绍有意想象的这两种类型。 1.再造想象: 再造想象是根据语言、文字的描述或图形、符号的描绘,在头脑中造出相应新形象的过程。例1、看(或听)了下面一段叙述:“△ABC
Imagination is the psychological process that creates a new image based on the original sensual images. In mathematics teaching, imagination is the student's free-flying wings in the mathematics kingdom, which not only needs a high degree of spatial imagination in the study of stereoscopic geometry, but also rich imagination in all branches of mathematics Indispensable First, the type of imagination According to imagine whether the purpose and consciousness, can be divided into intentional and unintended imagination. Imagination based on differences in novelty and originality can be divided into recreating the imagination and creating imagination. The following focuses on the two types of imagination. 1. Recreate the imagination: Recreate the imagination is the process of creating a new image in the mind according to the language, the description of the text or the figure, the depiction of the symbol. Example 1, see (or listen to) the following paragraph describes: "△ ABC
