This paper describes how elementary school students acknowledged our science e-learning site, "Science Net," in order to analyze the effectiveness of the site as a form of blended learning. The authors examine the relationship between the consequent effectiveness of learning via post-questionnaires and the frequency and purposes of students' access to "Science Net." The results show that the contents of "schedules of lessons" not only serve the purpose of allowing students to prepare for the next lesson but also provide useful science education. In addition, students report that they find it useful for checking lessons when they are absent as they are able to download worksheets and ask questions to the teacher via a bulletin board system (BBS). In addition, models imply that the students who access "Science net" frequently use the system not only as a means to review but also as a means to prepare for the future.
