Learning process
• Specialized equipment, auditorium
facilities, interactive whiteboards etc.
• Distance learning, Web Seminars –
Webinar
(Webex),
e-learning
(Blackboard, Moodle), m-learning
(mobile phones)
• Intellectual Tutoring Systems - ITS
(animated pedagogical agents, selfappraisal tests, tutoring robots).
• The sequence of curriculum is made so
that the student may easily adapt
himself/herself, besides material is
demonstrated to the student just when
he/she needs it.
• ITS gives detailed feedback to the
learner on the imperfect or false solution,
helping to learn from ones mistakes.
• Problem solving methods - little help is
provided to the learner, so the right
solution is achieved.

• ITS is an adaptive computer-based system
• ITS uses methods of artificial intelligence
(natural language processing, knowledge
representation – knowledge of problem
domain, pedagogical knowledge and
knowledge about student, inference, and
machine learning
• ITS ensures adaptive and individualized
tutoring, it partly simulates a human
teacher.
• ITS is based on tutoring and cognitive
theory.
• Assist learners in identifying their false
beliefs, becoming aware of their
misconceptions and inadequacies, and
reconstructing their knowledge.
• Help learners to determine performance
expectations, identify what they have
already learned and what they are able to
do, and judge their personal learning
progress.
• Support
learners
towards
the
achievement of the underlying learning
goals.
• In former studies e-learning systems mostly have been
formed as systems for information supply, where lectures
or distance learning materials are available in e-format.
• In the latest researches target has been set to
individualized e-learning system, directed to the student.
• Technology enhanced learning have adaptation gaps,
where one of the solutions is ITS – where realization of
adaptation is made, so that ITS is brought nearer to the
person’s ability to learn (best examples IKAS and
COMPASS).
• When analyzing existing ITS we may conclude that their
development is progressing, but still it is not at the level
where ITS fully realizes adaptive training.
• ITS drawbacks, elaborating and research is very current
topic because of e-learning privileges, thereby we may
consider development in the direction of ITS to
overcome their imperfections.
Thank you for attention!
