首先介绍了生物在中学阶段的作用,然后提出了初高中生物教学衔接的问题,包括:知识难度梯度跨度、学习时间的安排等。经过分析,提出了新时期初高中生物教学衔接的对策,包括:改变教学安排,避免学习“断层”出现;改变知识安排,让知识过度更为“平滑”;增加初高中教师培训,提高教师素质。 First introduced the role of biology in the secondary stage, and then raised the issue of early high school biology teaching convergence, including: the gradient of knowledge span, learning time arrangements. After analysis, this paper puts forward some countermeasures for the connection of high school biology teaching in the new period, including: changing teaching arrangement, avoiding the appearance of learning “fault”; changing the knowledge arrangement to make the knowledge more “smooth” and increasing the training of junior middle school teachers , Improve the quality of teachers.
