3.5.4 Cognitive State Transitions of Learners
of the Programming Tutoring System
Taking into account all the above, it can be concluded that a domain concept
passes through five states ('unknown', 'moderate known', 'known', 'learned',
'assimilated') during the interaction of the user with the system. Furthermore, a
learner passes through several states during the learning process. S/he can learn or
not, forget, assimilate or not etc. These states determine the progress of the learner
each time; they determine the transition from one KL stereotype to another. Also,
the transition from one KL stereotype to another can reveal the state of the learner.
Figure 3.10 depicts the transitions among the learner's cognitive states for the
presented programming tutoring system.
3.6 Examples of Operations
The presented programming tutoring system was used in a postgraduate program
in the field of informatics at the University of Piraeus, in order to offer dynami-
cally personalized e-training in computer programming and the language C.
The learners used the system without attending any complementary course on
programming, over a period of six months. They had different ages and diverse
