在教学地球宇宙内容时,因为在研究对象上不能或不允许进行实际实验,所以为了取得对研究对象的认识,通过模拟的方法,选定研究对象的代替物即模型,模拟研究对象即原型的实际情况,对代替物进行实验,这种实验就是模拟实验。这种实验具有科学实验和科学模型的双重特性,一方面,实验模型以 In the teaching of the Earth’s cosmic content, because the research object can not or does not allow the actual experiment, in order to obtain the understanding of the research object, the simulation method is used to select the research object instead of the model, and the research object is the prototype The actual situation, the substitute for experiments, this experiment is a simulation experiment. This experiment has the dual characteristics of scientific experiments and scientific models. On the one hand, experimental models
