On the instruction system of the space-time theory in the special theory of relativity

Unlike the existing textbooks, this paper approaches the teaching of the properties of space - time and the Lorentz transformation differently. From the three basic principles, the three space - time properties like clock dilation, moving length contraction and relativity of simultaneity are derived. Based on the above-mentioned points, the Lorentz transformation and the invariance of interval are obtained. In addition, some relevant issues in the teaching reform of theoretical physics have been discussed.
