如何结合物理教材把不同层次的科学方法落实到教学实践中去,是目前科学方法教育中亟待解决的问题之一。外推法作为一种较为典型的逻辑推理方法,对于物理学的发展,提供了理论创造的方法论依据,对于物理教学,它给学生以科学方法论的教育。本文试就此方法的处理谈点肤浅的意见。 How to combine physical teaching materials to implement different levels of scientific methods in teaching practice is one of the most urgent problems to be solved in scientific method education. Extrapolation, as a typical logical reasoning method, provides the theoretical basis for the development of physics. For physics teaching, it gives students a scientific methodological education. This article tries to talk about superficial opinions on the handling of this method.
