● Teaching using learning management system:
I made a break in this area. I pioneered teeaching online setting and constructed important resources inluding Mathematica codes, latex codes and math contents. I am currently developing and teaching 400 level courses towards master degree program. I am in charge of teaching 10 undergraduate courses and a main instructional developer.
Netmath is a uinque web-based distance-learning interface that has provided mathematics education to a wide range of student populations including Rural High School students, Post-AP High School students, home-schooled students, University students, Adult professionals, and Military personnel. Students who register for Netmath courses explore mathematical concepts with the aid of the computer algebra system Mathematica.
NetMath is the distance learning program of the Department of Mathematics at the University of Illinois at Urbana-Champaign. Our goal is to bring academic resources from one of the nation's top public universities to students around the world. I am developing the resources required to provide students with the unique method of learning that NetMath offers. For 25 years, the NetMath program has been breaking down distance barriers in education and making University based math courses more widely available for students throughout the United States and the world as well.

● Teaching:
I have 20 years college teaching experience. In detail, University of Illinois at Urbana-Champaign(over 13 years since 2003) and Governors State University at the south Chicago area (1 semester) and Kyungpook National University, S. Korea(over 4 years). I have a unique teaching experience as a mathematician. I have an outstanding college teaching experience, both traditional and non-traditional, and computer based teaching experience.
