Abstract. In recent years, the
learner models of some adaptive learning environments have been opened to the
learners they represent. However, as yet there is no standard way of describing
and analysing these 'open learner models'. This is, in part, due to the variety
of issues that can be important or relevant in any particular learner model.
The lack of a framework to discuss open learner models poses several
difficulties: there is no systematic way to analyse and describe the open
learner models of any one system; there is no systematic way to compare the
features of open learner models in different systems; and the designers of each
new adaptive learning system must repeatedly tread the same path of studying
the many diverse uses and approaches of open learner modelling so that they
might determine how to make use of open learner modelling in their system. We
believe this is a serious barrier to the effective use of open learner models.
This paper presents such a framework, and gives examples of its use to describe
and compare adaptive educational systems.
