4.运用“类比”化归已知的策略。 比较是人类认识事物的重要方法之一,类比更是认识新事物、发观新问题的有效途径。人类从锯齿草割破手指中受到启发生产出锯子;从研究鱼类在水中自由沉浮而制造出潜水艇;从鸟类的空中自由飞翔而发明了飞机;从模拟人脑的结构和功能,将电子计算机发展成电脑……所有这些,都是人类运用类比的思维策略进行发明创造的成功典范,将此思维策略运用到解题实践中就是类比的解题策略。 所谓类比,是依据两个(类)数学对象的类似性(这种
4. Apply “analogy” to known strategies. Comparison is one of the important ways for human beings to know things. Analogy is an effective way to recognize new things and develop new problems. Human beings have been inspired by the cutting of sawtooth grass to produce saws; from researching the freedom of floating and floating of fish in water to create submarines; flying from the air of birds to the invention of aircraft; from simulating the structure and function of the human brain, The development of computers into computers ... All of these are examples of successful inventions and inventions created by humans using analogous thinking strategies. Applying this thinking strategy to problem-solving practice is an analogy of solving problems. The so-called analogy, is based on the similarity of two (class) mathematical objects (this
