Adding immersive virtual reality to a science lab simulation causes more presence but less learning

Virtual reality (VR) is predicted to create a paradigm shift in education and training, but there is little empirical evidence of its educational value. The main objectives of this study were to determine the consequences of adding immersive VR to virtual learning simulations, and to investigate whether the principles of multimedia learning generalize to immersive VR. Furthermore, electroencephalogram (EEG) was used to obtain a direct measure of cognitive processing during learning. A sample of 52 university students participated in a 2 × 2 experimental cross-panel design wherein students learned from a science simulation via a desktop display (PC) or a head-mounted display (VR); and the simulations contained on-screen text or on-screen text with narration. Across both text versions, students reported being more present in the VR condition (d = 1.30); but they learned less (d = 0.80), and had significantly higher cognitive load based on the EEG measure (d = 0.59). In spite of its motivating properties (as reflected in presence ratings), learning science in VR may overload and distract the learner (as reflected in EEG measures of cognitive load), resulting in less opportunity to build learning outcomes (as reflected in poorer learning outcome test performance).     

拟古写真交融奇辞奥旨同辉——韩愈《琴操十首》的审美观照

韩愈的<琴操十首>是我国历代琴操诗的扛鼎之作.它借古鏊今,笞挞现实社会中的佞人专权,表达诗人憧憬圣贤的诉求;它巧妙地化用本事抒怀,展现了诗人的忠君意识、遗弃意识、反省意识和自赎意识相互交织的独特心灵世界;它奇辞与奥旨同辉,生命与意象叠印,以无我凸显自我,从而做到了古今贯通,物我无间,使音乐与诗歌完美地结合在一起,极大地推动了我国音乐文学的发展.

混合现实技术对学生学习绩效的影响研究——基于33项实验与准实验的元分析

混合现实(MR)作为虚拟现实(VR)和增强现实(AR)的高级发展阶段,以沉浸式、跨时空、强交互等特点在教育教学中得到广泛应用。但对国内外文献分析发现,学界对混合现实技术的教学应用效果仍有分歧,对学生学习绩效的影响研究存在较大差异。为探究混合现实技术对学生学习绩效的影响,研究采用元分析方法,对2010-2020年间国内外33项混合现实技术支持下的实验与准实验研究进行量化分析,其总样本量为1460,重点从学段、学科、实验周期和学习场所等调节变量进行深入探析。研究结果表明:混合现实技术对学生学习绩效具有积极的正向提升作用;同时,其应用效果受到学段、学科、实验周期和学习场所等调节变量的影响。依据元分析结论,研究对未来混合现实技术在教育教学中的应用提出了推进学段贯通式MR教学,加快MR与学科融合发展,整合碎片化MR教学资源等建议。     

Cultural Trends of Audience Online Interaction with Vocal Talent Shows: A Comparative Study between China and the US

This study examined cultural reflections online of audience comments on social network sites regarding vocal talent shows in China and the United States. The study applied dimensions of cross culture to investigate audience comments on the official social networking sites of The Voice of China and The Voice. Findings reflect Hofstede’s dimensions as applied to social media and illustrate how individuals alter their “local” cultural norms in the new media environment. The study specifically enhances the exploration of cultural manifestations in cyberspace, which fewer cross-cultural studies have researched.
