Nowadays modern society requires
every citizen always updates and improves her / his
knowledge and skills necessary to working and researching.
E-learning or distance learning gives everyone a chance to
study at anytime and anywhere with full support of computer
technology and network. Adaptive learning, a variant of
e-learning, aims to satisfy the demand of personalization in
learning. The adaptive learning system (ALS) is defined as
the computer system that has ability to change its action to
provide learning content and pedagogic environment/method
for every student in accordance with her/his individual
characteristics. Therefore, the ultimate goal of this
research is to give the best support to learners in their
learning path and this is an enthusiastic contribution to
research community. Learners’ information and
characteristics such as knowledge, goal, experience,
interest, background, etc are the most important to adaptive
system. These characteristics are organized in structure
so-called learner model (or user model) and the system or
computer software that builds up and manipulates learner
model is called user modeling system (or learner modeling
system). This research proposes a learner model that
consists of three essential kinds of information about
learners such as knowledge, learning style and learning
history. Such three characteristics form a triangle and so
this learner model is called Triangular Learner Model (TLM).
The ideology of TLM is that user characteristics are various
and only some information is really necessary to adaptive
learning and an optimal user modeling system should choose
essential information relating to user’s study to build up
learner model.
