Figure 2: GITS interface to add notes to contents.
Only for students with a very high preference for the
active style the GITS made an adaptation of the
learning activities to explore the potential and
students creativity. For students with a very high
preference for the reflexive and theorist styles, the
system did an adaptation on forums, to improve
reflection, and on the Chat for the Active style to
promote a direct discussion.
The GITS system modulate the user behaviour
based on the student learning style, but with a main
moderated preference for each style most of the
students had a standard view of the system. Only the
high and very high preferences change the
appearance of tools, contents and activities.
4 CONCLUSIONS
The use of intelligent systems has several
advantages in the support and personalization of e-
learning. The intelligent tutoring systems are
typically used in computer-based training (CBT) and
don’t support the collaboration and cooperation like
groupware and cooperative work technologies. We
propose the adoption of generative intelligent
tutoring system to support Web-based Educational
Systems.
The validation of the prototype was done through
data collection of the GIST prototype. We do two
case studies in two subjects, one in Introduction to
Computer Science and other in Web Development.
Based on the results we can conclude that the
adoption of collaborative and adaptive capabilities to
intelligent tutoring systems, like forums, and the
possibility to add notes to contents to share
knowledge, is a good feature to improve the learning
experience.
The organization of contents using learning
activities was highlighted as very important by most
of the students in the survey and the adoption of
learning styles to model the user profile was
considered important for the students.
The GIST system supports the student in their
learning activities, collaborative work, portfolio
management, agenda management, and shows
several points of view of some subjects, suggesting
Web resources to complement the student
knowledge.
These capabilities it was considered by the
students very important to improve the knowledge
and the collaboration, which can be adopted in
several learning management systems to provide a
more effective support in the learning process, going
in the direction of the needs of knowledge based
societies.
