Construction of Application Mode of Virtual Reality (VR) Technology in Hazardous Chemistry Experiment Teaching

Abstract

Traditional hazardous chemistry experiment teaching has long faced problems such as high safety risks, insufficient experimental resources and limited teaching effects. In order to solve these dilemmas, this study deeply analyzes the application advantages of VR technology in this field, and combines constructivism theory, situational cognition theory and embodied cognition theory to construct a complete set of VR teaching mode, covering the whole process of experimental preview, classroom teaching and review assessment. By creating realistic virtual experiment scenes, designing interactive operation links and establishing dynamic feedback mechanism, this model guides students to change from passive knowledge acceptance to active inquiry learning. At the same time, the in-depth application of VR technology in hazardous chemistry experiment teaching has accelerated the transformation of chemistry experiment teaching to digitalization and intelligence, provided new ideas for the reform of experimental teaching under the background of educational informatization, and helped to achieve the dual goals of cultivating students' experimental operation skills and safety awareness.
