The purpose of this study was to evaluate the effectiveness of a practical English program for college students which had been administered both on- and off-line. After over 1,400 freshmen took two TOEIC-based courses consecutively, questionnaires were administered to measure the students’ satisfaction of the program and their perceived usefulness of on-line learning. The effectiveness of the English program was measured through the improvement in the students’ TOEIC scores, their perceived usefulness of online learning, and their satisfaction with the program. The results showed a statistically significant increase in the students’ TOEIC scores in both semesters, with greater improvement in the second semester as compared to the first. Although the students’ overall perception of the usefulness of e-learning was in the middle on the scale, those who perceived online learning as useful were shown to have spent more time studying for the courses outside class, thereby improving their TOEIC scores and enhancing their level of satisfaction with the program. Pedagogical and research implications are suggested.
