To utilize information technology to improve learning processes, the pedagogical assumptions underlying the design of information technology for educational purposes must be understood. However, little theoretical development or empirical research has examined the learning effectiveness in web-based e-learning. In this regard, the primary purpose of this study is to investigate which factors of e-learning influence the effectiveness of education. Factors studied in this paper were the interaction in student, teacher and contents, the class characteristics and the self-efficacy. The results showed that the interaction and the class characteristics had the significant effects on the effectiveness of education. Moreover, the self-efficacy had a mediating effect on the effectiveness. However, the interactions had a partial significant effect on the self-efficacy and the effectiveness of e-learning. This result is partially due to the subject characteristics of this study because the subjects of this study are the students and they had already the experiences in IT and e-learning.
