摘要
力矩是高中物理教学的难点,建立杠杆模型可搭建初中杠杆和高中力矩之间知识的脚手架,突破教学难点,使学生运用迁移,解决知道力矩概念却不会解决力矩相关问题的情况,建构解决力矩平衡问题的思路.
Torque is a dificult point in physics teaching in high school.The establishment of leverage model can build the scafolding between the leverage and the moment during junior school and high school,break through the teaching dificulties,and enable students to use migration to solve the problem of knowing the concept of torque but not solving the moment related problems.Construct the idea of solving the problem of moment balance.
