The comprehension of chromosome movement during mitosis and meiosis is essential for understanding genetic transmission, but students often find this process difficult to grasp in a classroom setting. I propose a “double-spring model” that incorporates a physical demonstration and can be used as a teaching tool to help students understand this process, particularly the energy changes that occur during different stages of the cell cycle. My teaching experience has demonstrated that this model is very effective, and it has been favorably received by numerous students.
