Designers and evaluators of immersive virtual reality systems have many ide
as concerning how virtual reality can facilitate learning. However, we have
little information concerning which of virtual reality's features provide
the most leverage for enhancing understanding or how to customize those aff
ordances for different learning environments. In part, this reflects the tr
uly complex nature of learning. Features of a learning environment do not a
ct in isolation; other factors such as the concepts or skills to be learned
, individual characteristics, the learning experience, and the interaction
experience all play a role in shaping the learning process and its outcomes
. Through Project ScienceSpace, we have been trying to identify, use, and e
valuate immersive virtual reality's affordances as a means to facilitate th
e mastery of complex, abstract concepts. In doing so, we are beginning to u
nderstand the interplay between virtual reality's features and other import
ant factors in shaping the learning process and learning outcomes for this
type of material. In this paper, we present a general model that describes
how we think these factors work together and discuss some of the lessons we
are learning about virtual reality's affordances in the context of this mo
del for complex conceptual learning.
