This paper introduces an alternative teaching model in a virtual architectural design studio, its application, impacts and
constraints. This model aims for achieving collaborative learning through facilitating students to Inhabit, Design,
Construct and Evaluate (IDCE) their designs collaboratively in a multi-user real-time 3D virtual environment platform
(Activeworlds). The application of this model in virtual design studio (VDS) teaching has favorably impacted students'
motivation for active, creative and explorative learning, social dynamics between studio participants. It also fostered
learning electronic communication, collaboration techniques and etiquette in addition to design technology. The model
assisted in developing collaborative experience and shared responsibility. However, there are some drawbacks of the
virtual environment platform that hindered having a responsive design environment to users' needs with especially in
modeling and rate of viewing. The advantages and constraints of applying the IDCE teaching model in a multi-user
real-time 3D virtual environment for first year students at the University of Sydney are addressed in this paper.
