Construction and Effectiveness Evaluation of Virtual Reality-based Immersive Learning Environments in International Chinese Language Teaching and Learning

VR technology integrates a variety of high technologies, which can create virtual situations that can act on learners’ senses of sight, hearing, smell and touch. This paper proposes a strategy for constructing an immersive Chinese learning environment based on virtual reality (VR) technology, and designs an intelligent grouping strategy based on improved genetic algorithm. Meanwhile, the application effect of VR immersive learning environment in international Chinese teaching is experimentally analyzed. The results show that the grouping time of the improved genetic algorithm stays within the range of 5000~6000ms, which is lower than the grouping time of the pre-improved genetic algorithm. And the improved genetic algorithm can realize the selection of difficult and knowledge points in the test paper, and the knowledge point coverage rate is as high as 98.69%, which is higher than the basic genetic algorithm. This indicates that the improved genetic algorithm can improve the efficiency of material management and intelligence level of international Chinese teaching, and can realize human-computer interaction immersive teaching. In addition, the experimental group using the VR immersive learning environment improved significantly more than the control group in the four competency dimensions of vocabulary, sentence rewriting, reading, and composing (P<0.05), and the experimental group also had a more significant effect than the control group in terms of reinforcing students’ attitudes towards learning and interest in learning (P<0.05). The proposed immersive learning environment construction strategy based on VR technology is effective and can be used in international Chinese teaching practice.
