我在讲授《高中生物》课本第一章第三节“细胞的分裂”这部分教材时,为了突出重点和突破难点,除了应用幻灯投影片外,还把“植物细胞有丝分裂过程”的内容,写成歌诀,印发给学生。帮助他们理解和熟记这部分知识。通过实践证明,效果很好。现在抄录如下,供参考。 When I was teaching the textbook “Separation of Cells” in the first chapter of the third chapter of “High School Biology” textbook, in order to highlight the key points and break through the difficulties, in addition to applying the slideshow, I also wrote the content of the “plant cell mitosis process.” The ballad is printed and distributed to students. Help them understand and memorize this part of the knowledge. Through practice, it proved to be very effective. Now copy it for reference.
