一、背景“细胞增殖”是浙科版生物必修1第四章第一节内容,授课需2课时,该内容既是对细胞的结构和功能的巩固深入,也为学习减数分裂和遗传变异打下基础。因此,在教学中占有举足轻重的地位。但由于该节知识抽象、实物模型不够直观,又不是生活中所见,学生对本节知识感到难以理解,掌握不够扎实。要突破这个难点,我认为可以借助多媒体技术将细胞分裂的过程化静为动、化虚为实、化抽象为直观,同时合理设计教学程
First, the background “Cell Proliferation ” is the Zhejiang Section of Biology compulsory 1 Chapter IV of the first section, teaching takes 2 classes, the content is both on the cell structure and function of the consolidation, but also for learning meiosis and inheritance Variation lay the foundation. Therefore, occupy a pivotal position in teaching. However, due to the section of knowledge abstraction, the physical model is not intuitive enough, nor is it seen in life, students feel difficult to understand this section of knowledge, mastery is not solid enough. To break through this difficulty, I think that with the help of multimedia technology, the process of cell division can be static and dynamic, while virtualization can be intuitive. At the same time, designing teaching programs reasonably
