摘　　要：新高考模式下的选科与高校录取模式为大学物理教学带来了许多困难,如何在困境中对学生进行科学素养的培育是普通地方院校理工科教学面临的一大问题。本文从质心的基本定义出发,按照解决问题方法的由繁到简,为半圆形均质薄片质心的求解提供了六种解题方法,兼顾了对具有不同数学和物理基础的学生进行发散性思维训练的方式。在此基础上,探讨了新高考模式下大学物理教师在素质教育中应有的角色。The new college entrance examination mode brings many difficulties for college physics teaching.How to cultivate students'scientific literacy is a major problem for science and engineering teaching in general local colleges.Starting from the basic definition of the center of mass,this paper provides six kinds of problem-solving methods for solving the centroid of semi-circular homogeneous sheet according to the complexity of problem-solving methods,and gives consideration to the divergent thinking training for students with different mathematical and physical foundation.On this basis,the role of college physics teachers in quality education under the new college entrance examination mode is discussed.
