It is often observed that most international students are less likely to express their opinions in class. The lack of communicative engagement has negative impacts on students' academic performance. The objective of this article was to explore a range of possible explanations for international students' lack of engagement in class discussions and to seek a way to model how an e-tool could be applied to make international students more comfortable communicating. The present study viewed that those students' communication problems are induced by the following multiple factors: a sense of belonging to a minority, cultural difference, and communication apprehension. Blogs were thus suggested to enhance those students' communication contexts. An ideal model of blogging interactions between students and teachers was theoretically proposed. (Contains 4 figures.)
