Intelligent
Tutoring Systems (ITSs)
xPST - Extensible Problem-Specific Tutor
xPST - This open source intelligent tutoring system has been developed with NSF SBIR funding that is intended to enable teachers and faculty (or anyone) to create intelligent tutors on exinting software websites or for software for which you have the source code. More detail coming soon. Google Code site: http://code.google.com/p/xpst/
What's
an ITS?
An ITS is a artificial-intelligence
based method of learning that's much better than traditional
e-learning or simulations. Learn more in this 3-minute
presentation.
Why
would I need an ITS?
If
you spend too much time and money training customers
or support technicians how to use a complicated software
system, an ITS would help.
ITSs
have been shown to be much more effective than traditional
training (see references below):
- 30%
faster than traditional training for the same level
of mastery
- 30%
better learning in the same time
Why
haven't I heard of an ITS before?
ITSs
have historically been expensive to build and maintain,
but they have used very successfully in military flight
simulators and more recently in teaching
math. Clearsighted's technology makes the development
of an ITS much easier.
What's
the pedagogical theory behind an ITS?
ITSs
fall in the "problem-based learning" or
"learning by doing" category. The ITS gives
you a series of tasks to accomplish using the tool
that you're trying to learn. As you work, the ITS
tracks your learning and gives you personalized guidance
when you make mistakes. Gradually, the tutor fades
into the background as you master the material. Some
might also call this "cognitive apprenticeship."
