Abstract: This paper presents the open learner modelling capabilities offered
by an adaptive web testing tool. Adaptation decisions are based on user
customizable compound rules requiring the identification of several learner
characteristics which are then displayed graphically and textually to learners
and educators. The open learner modelling capabilities include anonymous access
to models of peers and restricted named access to friend peers. Opening the
learner profiles supports learner and educator involvement in decision making
so as to create a more credible learner model. The educational advantages of
the open learner modelling capabilities are discussed on the basis of an
evaluative study.
