The aim of this study is to investigate Taiwanese undergraduate students' perception of using computer-mediated communication (CMC) in a TOEIC preparation course and determine if using an online format motivates them to succeed. As a result, five factors are addressed in the study, namely, attitude, motivation, study habit, feedback, and collaboration. Particularly, a questionnaire was used to investigate these five factors related to students' perception of using CMC during a TOEIC preparation course. Additionally, Five Taiwanese university students who have experience of using CMC in a TOEIC preparation course at Taiwan Shoufu University in Tainan County were interviewed via Skype to ascertain their perception of using CMC. All the collected data are presented in descriptive statistics to illustrate the participants' demographic information and their responses to the survey regarding the use of CMC and the data from the Skype interview transcripts.
