【摘要】 疫情期间,大规模在线教学的主流模式是以视频会议系统为平台的同步在线教学。这类在线教学模式与传统的异步在线教学有很大区别,很难采用传统的在线教育理论来分析和解读,因而有必要开展针对这类在线教学模式的特征与核心构成要素的研究。为此,本文在教育资源信息中心(ERIC)上搜集了26篇聚焦在线同步视频教学的研究论文,进行了分析和综述。研究发现:(1)在线同步视频教学的典型特征是师生同时"在场",以及在线"面对面",因而显著提高了在线学习者的在场感、参与感和满意度;(2)同步视频教学跟面对面课堂教学有很多相似之处,教师应该提前规划课堂中的主要教学事件,并灵活运用平台提供的各种媒介工具,打造在线教学的"注意力焦点";(3)在线同步视频学习正在变成一种普遍的、高频的社会学习行为,在线视频会议界面成了交流"第一现场",而现场变成了"后台"。更多还原

【Abstract】 During COVID-19,synchronous video conferencing becomes the mainstream mode of online teaching.Hence,traditional online education theories may not be able to explain this kind of pedagogical practice effectively.The current study conducts a literature review of 26 research studies on synchronous online video teaching on ERIC in an attempt to identify the features and key components of such practice.Findings from the review show that when teachers and students "are present" synchronously,and communicate "online face to face",students’ sense of presence,engagement and satisfaction is significantly enhanced.It is also found that there are many similarities between synchronous online video teaching and face to face teaching in that both modes have learning activities planned in advance,making it possible to use different tools in the platform flexibly to emphasize "focus of attention".Finally,it appears that online synchronous video learning is becoming an increasingly popular social learning behavior.Put another way,the online video conference interface has become the "first scene" of communication,while the physical scene has become the "backstage".更多还原
