在几何教学中,有许多图形需要学生熟练掌握,这些图形既包括定义、定理的代表图形,也包括在几何中经常遇到的图形,以及由一个实际问题抽象为用数学符号表示的数学问题,这些图形或数学问题我们都称之为数学模型.当遇到一个几何图形问题时,我们能辨认它属于哪一类基本模型,或是由哪些基本模型复合而成.以此为索引,在记忆贮存中提取出相应的方法来加以解决,这就是利用数学模型的解题策略.
In geometry teaching, there are many graphics that students need to master. These graphics include not only the definition, the representative graphics of the theorem, but also the graphics often encountered in geometry, and mathematical problems abstracted from a practical problem to a mathematical symbol. These graphic or mathematical problems are called mathematical models, and when faced with a geometry problem, we can identify which basic model it belongs to, or what basic models it is composed of. As an index, Storage extracted from the corresponding method to be resolved, this is the use of mathematical models to solve the problem strategy.
