细胞分裂是教材的一个难点,内容抽象且难度大,不易突破,学生难于掌握。在复习教学中仅帮助学生进行一般的总结和比较往往起不到好的效果。我采用案例教学法,从分析题目着手,指导学生回忆并运用知识,既掌握了知识,又学会了分析问题的方法,对于突破难点,培养理论联系实际的学习方法,提高学生的能力,增强教学效果有着显著的作用。
Cell division is a difficult part of textbooks, and the content is abstract and difficult, and it is difficult to break through. It is difficult for students to grasp. In reviewing the teaching, only helping students to generalize and compare often does not produce good results. I use the case teaching method to start from the analysis topics and guide students to recall and apply knowledge. They not only master the knowledge, but also learn how to analyze the problem. They can overcome the difficulties and cultivate the theory-to-actual learning method to improve students’ ability and enhance teaching. The effect has a significant effect.
