“染色体组”这个概念是学习染色体数目变异中二倍体和多倍体概念的基础,正常教学时,学生难以理解,特别是学生对“染色体组”的分类方法和标准不明确,所以给后续的学习带来了困难。笔者通过学生自主探究,亲身体会的教学方法,达到了事半功倍的效果。 The concept of “genome” is the basis for learning about the concept of diploid and polyploidy in the variation of the number of chromosomes. It is difficult for students to understand during normal teaching. In particular, students’ classification methods and standards for the “genome” are not clear , So to follow-up study has brought difficulties. The author achieves a multiplier effect through students’ self-exploration and personal experience of teaching methods.
