ReTuDiS (Reflective Tutorial Dialogue System) is
a dialogue-based Open Learner Modelling System designed to support
Web-based instruction. Open learner modelling engages the learner
in the diagnosis process. Open issues in this area remain: the way
of conveying information about learner modelling to learners, the
learners' role as participants in the learner modeling process,
the extent to which the selected components of learner modelling
are made overt to the learner and the maintenance of learner models.
In our research we concentrate on the learners' role as participants
in the learner modeling process and we have proposed an open learner
modelling approach for modelling learners' text comprehension, which
is based on dialogue. This approach provided the theoretical basis
for the design of ReTuDiS, which generates appropriate tutorial
dialogue based on the Theory of Inquiry Teaching with the aim of
promoting learner's reflection. Our current plans concentrate on
the diagnosis of learner's computer science text comprehension and
historical text comprehension. (http://hermes.di.uoa.gr/RETUDIS/retudis.htm)
