This study focuses on investigating the correlations of university freshman students’ actual learning
behaviors with their personal behavioral intentions, attitudes,language abilities,and self-efficacy in using
on-line practice exams for their English acquisition. The targeted participants were 238 freshman
students who have experienced two semesters of American Magazine Center’s on-line practice exam
training requested by the school. The researcher adapts Ajzen’s Theory of Planned Behavior (TpB)
Model and utilizes survey questionnaires as research tools to study how and to what degrees do
students’attitudes, language abilities,and self-efficacy correlate with their intentions and actual behaviors.
The purpose of this study is also to find out the determining factors that predict students’ intentions and
that ultimately affect students’learning behaviors as these variables could result the success of the
utilization of on-line English practices. Analyzed by path analysis and step wise regression analysis, the
collected data indicated that there are significant correlations among all the variables except
students’ attitudes with their self-efficacy. The result of this study implicated that the success of
students’English practices on line heavily relies on their attitudes toward the exam program,language
abilities, and self-efficacy in computer operation as these variables are positively correlated with their
behavioral intentions which also significantly affect their actual behaviors. Thus, the findings of this study
have theoretical and practical implications for strengthening the learning effectiveness of students’use of
on-line English practice exams.
