This study aims to investigate learners’ perception of online learning for a general English course in Covid 19 situation, explore how online class preference affects degree of satisfaction of general English online class and examine whether the influence varies depending on the controlling variables such as age, instructor, English level, and English preference. The subjects of this study were 870 undergraduate students from K University who took the same compulsive general English course, and the survey was conducted through the Google Forms questionnaire. This study processed an independent sample-t test, response sample-t test, and Pearson correlation analysis to discover the effect of bichronous online learning(blending of both asynchronous and synchronous online learning) preference on English class satisfaction, and hierarchical multiple regression to observe the effect of online class preference. The results showed that students' preference to online learning was lower than that of online learning, but in the case of their satisfaction of general English online course, satisfaction with the synchronous online class was higher than that of the online class. In addition, There was a high positive correlation between synchronous online learning preference and general English class satisfaction. It was also found that the hierarchy of factors influencing English class satisfaction was in the order of synchronous online learning preference, English preference, online class preference, and English proficiency level.
