Abstract

Objectives The purposes of this study is to identify the characteristics and elements of exemplary remote learning, provide factors that control the quality of effective remote learning, and present implications according to the educational environment changed by the COVID-19 situation.
 Methods For this study, a total of 324 students(1,178 case) and 459 instructors(459 case) in University A located in Seoul were surveyed using Google Survey, and the collected data was analyzed through topic modelling’s LDA method.
 Results Survey results show that instructors and students each perceived four topics of remote learning elements. Topics extracted from the students’ surveys are “prompt response to problems that occur”, “difference in the quality of lectures according to the instructors’ design of remote lectures”, “systematic preparation of remote learning and good communication”, and “recreating a curriculum that is suitable for remote learning”. Topics extracted from the instructors’ survey are “supporting the environment and equipment needed for remote learning”, “specific guidelines for remote learning”, “provision of clear grading guideline for remote learning”, and “good communication in remote learning.”
 Conclusions The results of this study present practical implications for smooth remote learning, such as the need for both students and instructors to have basic media literacy necessary for remote learning and the need to redesign teaching and learning to fit the remote learning environment(e.g., systematic redesign of lectures, interaction, class evaluation criteria, etc., appropriate for remote learning), and propose future research topics.
