摘要

摘要本研究的目的是研究如何通过结合多媒体学习认知理论中的多媒体原理来增强使用Zoom的在线同步教学。进行了一项现场讲座教学实验，学生被随机分配参加Zoom的标准课程（控制条件）或相同的课程，但在整个课程中应用了多媒体原理（信号、体现和生成活动原理）（治疗条件）。结果显示，用CTML原理教学对学生的学习有直接影响，但没有证据表明工作记忆过载会产生间接影响。此外，学生对加入CTML原则的（同一位）教师更有影响力。为使用Zoom教学的教师提供教学启示和建议。

A zoom teaching experiment using CTML principles of multimedia design

ABSTRACT The purpose of this study was to examine how online synchronous teaching using Zoom might be enhanced by incorporating multimedia principles from the cognitive theory of multimedia learning (CTML). A live lecture teaching experiment was conducted where students were randomly assigned to attend a standard lesson on Zoom (control condition) or the same lesson but with the multimedia principles (signaling, embodiment, and generative activity principles) applied throughout lesson (treatment condition). Results revealed a direct effect of teaching with CTML principles on students’ learning, but there was no evidence for an indirect effect through working memory overload. Additionally, students had more affect toward the (same) instructor who taught with added CTML principles. Pedagogical implications and advice are offered for instructors who teach using Zoom.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
