Abstract
Undergraduate education at Rensselaer Polytechnic Institute has been transformed by the campus-wide use of interactive learning and studio teaching. Rensselaer's 80/20 Model for interactive distance learning is a natural extension of its on-campus educational environment and will form the foundation for the future development of professional and distance education at the Institute. This paper provides an introduction to the evolution of the 80/20 Model, a description of the techniques, technologies and design strategies involved in developing the synchronous and asynchronous components of an 80/20 course, and an overview of implementation issues.
