Abstract
We introduced blended learning, which is the mix of in-person and e-Learning system, into some lectures on mathematics in 2003. After some improvements, this blended learning has been introduced into a first course in linear algebra, which many new students have been taking since 2005. As a result, their scholastic ability in this course has been improved. This paper describes the nature of this learning and its effects. Moreover, we present the change of their scholastic ability and interesting data on this blended learning.
