The purpose of this study was to examine online instructors' experiences and perceptions of online teaching and their communication with students in an online environment. More specifically, the study focused on the questions regarding: (1) instructors' general experiences and perceptions of online teaching; (2) instructors' general experiences and perceptions of online communication; (3) instructors' likes and dislikes about online synchronous and asynchronous communication; (4) factors affecting instructors' adoption of synchronous communication mode; (5) strategies that instructors used to facilitate online communication; (6) instructors' perceptions of the impact of different communication mode on learning; and (7) difficulties instructors have encountered for online teaching and communication. By examining the current practices of teaching and communication in synchronous and asynchronous online environments from instructors' perspectives, it was hoped that this paper would provide insights and guidance for distance education.
