This course originates at Western Carolina University
and is broadcast on NC Research and Education Network (NCREN) to
universities and colleges across the state. It is currently received
at NC State University, University of North Carolina at Wilmington,
University of North Carolina at Asheville, University of North Carolina at
Greensboro, NC Central University, Appalachian State University, and Elon
University. Some lectures are given from University of North Carolina at
Wilmington. The course is being developed with partial support from the
National Science Foundation and the University of North Carolina Office of
the President. The course development team at Western Carolina University
includes Dr. Mark Holliday, and undergraduate students Jeffrey House and
James Ruff. |
