Abstract
In this paper, we conduct a questionnaire survey on the actual conditions and the test on the basic scholastic ability of the students who register for the course, Introduction of Business Mathematics. We want to find the ways to improve the teaching-learning methods for this course. Especially, the registered students have difficulties in the following the course because they have not studied Calculus in their high school. So we give them several assignments on the Webwork system, an internet based homework management system, and analyze its effect on the students' scholastic achievement. And we propose a teaching-learning method suitable for the course.
