Online education is a form of teaching and learning that takes place via a computer and communication networks (Kearsley 1997). The Internet and its related technologies provide an additional option for students to take classes virtually anytime and anywhere. This study reports a quasi-experimental comparison of learning outcomes between a group of on-campus students and a group of on-line students. Both groups took the same course conducted by the same instructor during the same semester. They received the same set of assignments, quizzes, and examinations. This study has found that students who attend an on-line section has better overall grade than those who attend an on-campus section. It appears that students can successfully learn the course's fundamental concept in the on-line environmental setting.
