Turn the camera on to get better grade: Evidence from a field experiment
The economics literature provides mixed results on the effect of online classroom technology on student outcomes. An emerging body of behavioral studies suggests that videoconferencing is a cognitively exhausting activity and that the camera that is a salient feature of virtual meetings is a leading cause of this fatigue, with a more pronounced effect on women. Thus, economists and behavioral scientists debate whether online education and its technology provide an effective method of instruction. We use a field experimental design to examine how camera use in online synchronous economics classes affects learning outcomes. We find that changing the method of student engagement from turning the camera off to turning it on increases quiz grades by 0.18 standard deviations while we control for students’ gender and aptitude.
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.
