Abstract
Dueto thespread ofthecoronavirus, thelearningmode must bealtered to onlinelearning. To maximizetheeffectiveness of onlinelearning, flipped learning isemployed by many instructors. Theinstructorsapply thetechnology as thefacilitator in thelearning process. Specifically, inBinus University, the onlinelearning isconstructed by usingZoomfor the synchronous sessionsand Binus Mayaas the LearningManagement System(LMS) for theasynchronous sessions. However, therearesomechallenges found in thelearning process namely thelack ofstudents’ interactions, the obstacles found by thestudents in utilizing thetechnology,and lack ofengaging activities for thestudents. Therefore, this study aims to figures out theeffectiveness ofthetechnology utilization during thesynchronousand asynchronous sessions in teachingEnglish for WrittenBusiness Communication (EWBC) courseat BINUS University,especially the utilization ofe-learning platforms such as Zoomand Microsoft Teams inmaximizing theimplementation offlipped learning and students’ learning experienceespecially thestudents’ interaction in onlinelearning.
