Japanese educational facility has serious problems for the decline of students' basic ability of science and mathematics. We studied mathematical materials for e-learning system throughout the working group in the collaboration with the university, the high school, and the junior high school. Furthermore, we developed the e-learning system and the corresponding contents and examined the practical use in each educational facility. Especially, the contribution to the students' learning ability was confirmed through the remedial course of mathematical class in the university.
