虚设法解题有利于拓展学生物理思维的深度和广度,它能够简化解题思路,找到解题方法,提高解题效率.它是将合理虚拟与假设相结合的一种思维方法,可以打破学生知识的局限、问题条件的缺少、物理模型的生疏,从而引导学生顺利解题,是一种行之有效的处理物理问题的方法.本文将从六个方面来阐述虚设法在解物理题中的应用.
It can help to broaden the depth and breadth of students ’physical thinking by simplifying the way of solving problems, finding solutions to problems and improving the efficiency of solving problems.It is a way of thinking that combines reasonable hypotheses with virtual hypotheses to break down students’ The limitations of knowledge, the lack of conditions and the unfamiliarity of the physical model lead students to solve the problem smoothly, which is an effective way to deal with the physical problems.This article will explain the six aspects of the virtual law in solving the problem of physics application.
