[ACT-R-users] Skill Acquisition and the LISP Tutor

[Le Nguyen-Thinh]

Dear colleagues,

i am reading the paper with name above published in Cognitive Sicence 1989 and am wondering the sentence "As the students works on an exercise, the tutor monitors the student's input, essentially on a symbol-by-symbol basis".

My questions are:
- does the model tracing approach force the tutor to monitor the user's input "on a symbol-by-symbol basis"?
- as a programmer, i would jump to any where in my code. Is there presently a solution for the "problem" mentioned above?
- is it possible to test a tutoring system developed on the model tracing basis, so that i have a better feeling how this approach works?

thanks a lot.
