在高中生物教学中,由于“细胞增殖”本身的抽象性以及涉及知识面较广等原因,使其成为教学的一大难点,在复习中也成为学生难以突破的问题。教学中,我们可以以“染色体的行为变化”作为出发点来更好地理解“细胞增殖”相关问题。一、细胞增殖教学重点分析高中生物中,对于“细部增殖”的教学要求是理解水平,从教学大纲的角度出发,学生能够理解细胞有丝分裂过程并且能够阐述便可。但是,在教学实践中,我们看到是学生很难准确地描述这一
In high school biology teaching, due to the “cell proliferation” itself abstract and involves a wide range of knowledge and other reasons, making it a difficult teaching, in the review has become a difficult problem for students to break through. Teaching, we can “chromosome behavior changes” as a starting point to better understand “cell proliferation ” related issues. First, the focus of cell proliferation teaching High school biology, for the “fine proliferation ” teaching requirements is the level of understanding, from the syllabus point of view, students can understand the cell mitosis process and can explain. However, in teaching practice, we see that it is difficult for students to accurately describe this
