An online learning community enables learners to access up-to-date information via the Internet anytime–anywhere
because of the ubiquity of the World Wide Web (WWW). Students can also interact with
one another during the learning process. Hence, researchers want to determine whether such interaction
produces learning synergy in an online learning community. In this paper, we take the Technology Acceptance
Model as a foundation and extend the external variables as well as the Perceived Variables as our
model and propose a number of hypotheses. A total of 436 Taiwanese senior high school students participated
in this research, and the online learning community focused on learning English. The research
results show that all the hypotheses are supported, which indicates that the extended variables can effectively
predict whether users will adopt an online learning community. Finally, we discuss the implications
of our findings for the future development of online English learning communities.
