Application of interactive 3D simulation technology in innovating teaching methods for automotive technology at a college in Central Vietnam

Abstract

Automotive vocational training often faces difficulties in explaining the structure and operating principles of chassis systems because physical models are bulky, costly, and limited in their ability to demonstrate kinematic movement. This study presents the development and application of a web-based interactive 3D simulation system to support teaching innovation at a college in Central Vietnam. The system enables learners to rotate models 360°, separate structural layers, select components, access technical information, and view integrated instructional videos. Implemented in Automobile Technology teaching, the system was evaluated through classroom use and feedback from students and teachers. The findings show that the 3D simulation improved understanding of internal structures and operating principles, increased learner engagement and confidence, and supported a more effective integration of theory and practice. Teachers also reported that the system made lessons more vivid and practice-oriented. In addition, the simulation reduced dependence on expensive physical models and provided a safer, more accessible learning environment. The study suggests that web-based interactive 3D simulation is a practical solution for improving automotive vocational education and advancing digital transformation in teaching and learning.
