野生观赏植物多星韭染色体观察在《生命科学概论》“遗传学专题”翻转教学中的应用实践

The Application of the Chromosome Observation of Allium wallichii Kunth in the Flip Teaching of “Special Topics in Life Science”

在《生命科学概论》遗传学教学专题中,采用开放式实验管理模式,以小组为单位对丽江野生观赏植物多星韭有丝分裂过程进行观察,得出多星韭具有14条染色体,为二倍体。这种教学组织形式不仅能加深学生对细胞有丝分裂过程和染色体的理解,激发学生对生命科学知识的学习兴趣,同时提升学生的自主实验能力。通过这种翻转式教学改革与实践,为同领域、同学科课程的多样化教学提供参考。

In the ＂Introduction to Life Science＂course on genetics,an open experimental management model was adopted to observe the mitosis of the wild ornamental plants Allium wallichii Kunth in Lijiang using groups as a unit. There were 14 chromosomes,which were diploid plants. This kind of teaching form could not only deepen students’ understanding of plant mitosis and chromosomes,but also increased students’ interest in learning about life sciences,and at the same time,it improved students’ ability of independent experiments. This kind of flipping teaching practice could provide reference for diversified teaching in the same field and the same subject curriculum.
