University students’ perceptions of the effects of online lecture types and its media types

This study examined undergraduate students’ perceptions of effects of online course types such as face-to-face classes, online classes, and blended classes using survey data from 331 students during three semesters from 2020 to 2021. There were differences in effects using ‘PPT video’, ‘voice only in PPT’, and ‘real-time zoom’ between theoretical courses and practice courses. In terms of media types for online classes, ‘PPT video’ was perceived as the most effective type by students, followed by ‘voice only in PPT’, ‘real-time video’, and ‘blended media use’ meaning a 2-hour-course mixed with 1-hour PPT video and 1-hour-real-time video. The effectiveness of ‘real-time video’ and ‘blended media use’ was gradually decreased as time went by. Students had difficulties in academic achievement and daily life with online learning. They were eager to return to face-to-face classes after COVID-19 passes. Some online learning media types were preferable to use for face-to-face classes after COVID-19. © 2021 The Korea Association of Teachers of English (KATE)
