关于狭义相对论时空观教学的探讨

A DISCUSSION ON THE TEACHING OF THE SPACE-TIME VIEW OF THE SPECIAL RELATIVITY

狭义相对论的时空观是大学物理教学中的重点内容,而反映狭义相对论时空观的同时的相对性、动钟变慢和动杆收缩效应是教学的难点。本文首先通过分析学生学习的难点所在,解读狭义相对论时空观与经典力学时空观的本质区别,然后通过典型例题教学,巩固狭义相对论的时空概念,解决学生盲目地将原时、静长等时空概念与狭义相对论中的静系与动系机械对应的问题,从而使学生真正理解相对论的时空概念,理解狭义相对论的时空观。

The view of space-time in special relativity is the key content in college physics teaching. It is also a difficult teaching. By analyzing the difficulties of student learning, this paper interprets the Essential Difference between the View of Time and Space of the Theory of Special Relativity and Classical Mechanics. Then through the teaching of typical examples, consolidate the concept of space-time in special relativity. In this way, students can truly understand the concept of special relativity's space-time and the view of space-time in special relativity
