摘要
虚拟现实(Virtual Reality,VR)技术因在交互性、沉浸性和认知性方面具有独特优势而被认为是一种能够促进教育教学发展的新型手段,但是,VR技术在教学中发挥效用的内在机制还有待深入考证。教学效用是衡量技术能否发挥教学效果及其程度的指标,具体包括学习参与、教学效率和教学效果三个维度。结合VR的技术优势和教学效用维度、经由理论演绎建构的基于VR技术的教学效用模型(VR-E3Model),聚焦于研究VR的交互过程、沉浸过程和认知过程三方面效用。其中,影响交互性效用的因素包括软件因素、硬件因素、感知有用性、感知易用性、行为意向、学习者特征等;影响沉浸性效用的因素包括感知、交互感、沉浸感、临场感等;影响认知性效用的因素包括情绪信息、知识建构、认知发展等。经过实证研究检验表明,该模型具有较好的理论解释力;VR技术产生教学效用的首因要素是教师的教学行为意向;VR技术因软硬件的差异,会为使用者带来不同的交互体验;学校在配置VR设备时应从教学需求和成本投入两个维度进行综合考量。
Virtual Reality(VR),due to its unique benefits of connectivity,immersion and appreciation,is considered an effective way of promoting students’learning and the teaching process.However,the mechanism of VR technology effectiveness in teaching still needs further research.Teaching Effectiveness is an indicator to measure how technology method plays a role in the teaching process,including learning engagement,teaching efficiency,and teaching effectiveness.Based on the theoretical research and model construction,this research presents the VR-E^(3) model,which focuses on the VR interaction,immersion and recognition process.The VR interaction variables include hardware,software,perceived usefulness,perceived ease of use,behavioral intention,learners’characteristics and etc.The VR immersion variables include perception,interaction,immersion and presence.The VR recognition variables include information of emotion,knowledge construction,recognition development and etc.The VR-E^(3) model illustrates the VR teaching mechanism well based on data analysis and entropy method.It is found that teachers’behavioral intention is the most significant variable for VR teaching effectiveness.Because of the software and hardware disparity,VR teaching can offer users different immersive experience.And two dimensions of teaching demand and cost feedback should be taken into account for VR facilities allocation of schools.
