摘要/Abstract

摘要： [ 目的 / 意义 ] 人工智能的发展为传统教育教学带来了新的发展契机，引入了虚拟教师这一全新的人工智能教育主体，并由此产生了更为新颖的人智交互教学形态。探索人智教学交互中教学信息呈现方式与虚拟教师拟真度的作用，将有助于提升学习者在全新沉浸式环境中的学习效果，为未来以虚拟教师为主体的理想课堂建设提供方向。[ 研究设计 / 方法 ] 聚焦于人智教学交互情景，招募54名参与者进行了一项3（信息呈现方式：文字 / 图片 / 视频）×2（拟真度：超写实 / 卡通）的被试间受控实验，参与者被随机分配到6个组中并观看相应的教学视频，通过前后测问卷对参与者的学习体验效果进行测量。[ 结论 / 发现 ] 在虚拟教师授课的人智交互中，信息呈现方式对学习效果具有显著影响，视频带来的学习效果要显著优于文字和图片；上述影响只有当虚拟教师的拟真度较高时才存在，对卡通版虚拟教师而言，不同信息呈现方式带来的学习效果并无显著差异。[ 创新 / 价值 ] 聚焦于虚拟教师这一新颖的人工智能教学代理，通过受控实验精准度量用户学习体验，突破了经验设计的局限，为虚拟教师视觉特征及其教学信息呈现的优化提供了科学依据，丰富了以虚拟教师为主体的教学课程的基本设计原则。

Abstract: [Purpose/Significance] With the development of artificial intelligence, virtual teacher has emerged as new artificial intelligence pedagogical agents, and a new forms of education has also appeared. This study aims to explore the role of knowledge presentation modes and virtual teachers' simulation fidelity in Human-AI pedagogical interaction so as to provide new possibilities for improving learning effect in the immersive environment and provide guidance for curriculum construction. [Design/Methodology] Under the scenario of HumanAI pedagogical interaction, 54 participants were recruited to complete a within-subjects design experiment of 3（knowledge presentation mode: text/picture/video）×2（degree of realism: hyper-realism/cartoon）. Participants were randomly assigned to one of six groups and watched the corresponding instructional videos. The learning effects of participants were measured through pre- and post-test questionnaires. [Findings/Conclusion] In Human-AI pedagogical interaction with virtual teachers, the mode of knowledge presentation has a significant impact on the learning effect and the learning effect of video is obviously better than that of text and pictures. These effects are only observed in virtual teachers with high-fidelity simulation, while there are no significant difference in the learning effects of different knowledge presentation modes in the low-fidelity simulation condition. [Originality/Value] Focusing on virtual teacher, a new artificial intelligence pedagogical agent,this study accurately measures the user learning experience through controlled experiments, which breaks through the limitations of experiential design and provides a scientific basis for the optimization of the virtual teacher visual features and its knowledge presentation modes, and enriches the basic design principles of teaching courses centered on virtual teachers.
