随着《普通高中生物课程标准(实验稿)》中“模型”的提出,模型教学方法在高中生物教学中逐渐被重视。物理模型作为模型教学的重要形式,在物理、化学、生物等多种学科中应用广泛,其最突出的优点就是直观性,接近学生的认知,便于理解。以“减数分裂中染色体变化”为例浅谈物理模型教学。 With the proposal of “model” in “Ordinary High School Biology Curriculum Standards (Experimental Draft)”, the model teaching method is gradually taken into account in high school biology teaching. As an important form of model teaching, the physical model is widely used in many disciplines such as physics, chemistry, biology, etc. The most prominent advantages are intuitive, close to the student’s cognition, and easy to understand. Taking the “chromosome change in meiosis” as an example to discuss the physical model teaching.
