细胞的减数分裂主要是细胞核里染色体规律的变化。染色体是肉眼所不能看到的,为使学生能够建立染色体动态变化的空间概念,就要把染色体从微观引向宏观,于是设计出“模型模拟教学法”(我们给予的命名)。所谓模型模拟,就是用简易的染色体模型,模拟染色体的动态变化过程。 The meiosis of cells is mainly the regular change of the chromosome in the nucleus. Chromosomes can not be seen with the naked eye. In order to enable students to establish the spatial concept of chromosomal dynamics, the chromosomes should be led from the micro level to the macro level. Therefore, “model simulation teaching method” (named after us) is designed. The so-called model simulation, is to use simple chromosome model to simulate the dynamic process of chromosome changes.
