地铁站消防应急火灾逃生虚拟教学实证研究

Empirical study on virtual teaching of fire emergency escape in subway station

为探究地铁站消防应急火灾逃生教学过程中,不同学习场景对学习者学习效果的影响,发掘虚拟现实学习优势,采用调查问卷和MP160生理仪,获取纸质学习、移动端视频学习和虚拟现实学习场景下,学习者不同的行为反应数据,并处理和分析这些数据。研究结果表明:3种学习场景下,学习者的学习成绩存在显著差异,相较于移动端视频学习和纸质学习场景,虚拟现实学习场景能够促进学习者对地铁火灾逃生知识的理解,显著提高学习成绩;3种学习场景下,学习者的学习兴趣存在显著差异,虚拟现实学习场景在提升学习者对地铁火灾逃生知识的学习兴趣方面表现出显著优势;虚拟现实学习场景在生理指标方面体现出更高水平的生理唤醒。

In order to explore the influence of different learning scenarios on the learning effect of learners in the teaching process of fire emergency fire escape in subway stations,and explore the advantages of virtual reality learning.Questionnaires and MP160 physiological instrument were used to obtain different behavioral response data of learners in paper learning,mobile video learning and virtual reality learning scenarios,and these data were processed and analyzed.The results show that there are significant differences in learners'academic performance under the three learning scenarios.Compared with mobile video learning and paper learning scenarios,virtual reality learning scenarios can promote learners'understanding of subway fire escape knowledge and significantly improve academic performance.Under the three learning scenarios,there are significant differences in learners'interest in learning.Virtual reality learning scenarios show significant advantages in improving learners'interest in learning subway fire escape knowledge.The virtual reality learning scene reflects a higher level of physiological arousal in terms of physiologic index.
