Abstract: Lorentz transformation is the core content of special relativity. It is of great

significance to understand and master the conceptual connotation of Lorentz transformation

for further understanding the space - time view of special relativity. In this paper,the

nature of time-space transformation called clock slowing and scale reduction and the

speed of light invariance condition are studied based on the two-dimensional rotation of the

space-time dia- gram. It enables students to understand the Lorentz transformation more

intuitively and lays the foundation for subse- quent courses.

Key words: college physics, classroom teaching, special relativity, Lorentz transformation, two-dimensional rotation transformation
