The purpose of this study is to explore the experiences of university instructors who teach online. Data collections were documents, reading texts, recorded files, and photos and then analyzed by content and classification analysis, The results of this paper were as follows; first, participating professors are reflecting on whether they are taking weekly filling classes as class designers and operators through face-to-face and non-face-to-face meetings. Second, it was helpful when reading and speaking information, materials, and texts about the online classes were shared at the meeting, but the professors confessed that a negative perception of one's own online classes is a strong obstacle reflected in the classes, and the teaching strategies and time required for online classes was insufficient. Third, compared to the situation of face-to-face teaching according to the students’ responses and attitudes, the online teaching sees the instructor, who in front of the student can be seen on the screen as an ‘alone person' who plays with the body. Finally, we agree that self-development is more necessary as for an instructor’s ability than it is now, but if the instructor handles online technologies and methods well, the achievement of teaching goals and fundamental purpose of education should not change.
