Welcome to ecourse.org: the Information Infrastructure for Education in the information age! This system allows instructors from any school or college (including home schools and training programs) to teach either onsite or online courses . It allows students to manage all their ongoing school works and past academic records at one location.
Our mission is to redefine the model of learning and re-engineer its process by providing innovative administrative and instructional technologies. Click here for our beliefs.

comparing which model parameters improve the likelihood alpha=1, beta=1, alpha=1, beta = 2, ... more >>
This system is designed and developed by Professor Liping Liu with financial support from Southern Illinois University at Carbondale. It evolved from a prior version called CourseWeb (for courses prior to Year 2000) and UXTEND.COM and www.e-course.org.
