Please bear with me as I am explaining in a bit details about my problem
status.
I am designing an Intelligent Tutoring System using JESS and J2EE.
My ITS's teaching cycle is as follows:
present learning material -> present one/more examples -> assess learning
outcome through MCQ or fill_in_gap type questions. In between there will be
feedbacks to maintain learner's positive motivation level.
My domain knowledge will structured hierarchically as
domain_subject -> module-> topic-> concept. each concept consists of 3
types of Learning objects (theory, example and question).
The jess rules will decide the next learning object, which feedback message
to display and when, etc.
Below I am giving in brief some of my templates and jess rules in textual
format:
(deftemplate student
(slot stud-id) (multislot stud-name) (slot performance-history)
(multislot stud-clas) (slot session-no))
(deftemplate concept
(slot parent-topic) (multislot lo-names) (multislot lo-ids) (multislot
concept-name) (slot concept-id) (slot status) (slot stud-id) (multislot
pre-req-concept) (slot next-concept) (slot prev-concept))
(deftemplate learning-object
(slot parent-concept) (multislot lo-name) (slot lo-type) (slot lo-id)
(slot reqd-time)
(slot elapsed-time) (slot diff-level) (slot status) (slot attempt-count
(default 0)) (slot stud-id) (slot prev-lo) (slot next-lo))
Some of the rules in textual form
"1. if learner succeeds in a problem of difficulty-level 'EASY', next
select a problem of difficulty-level 'MEDIUM'"
"2. if learner succeeds in a problem of difficulty-level 'MEDIUM', next
select a problem of difficulty-level 'TOUGH'"
"3. if learner fails in a problem of difficulty-level 'MEDIUM', next select
a problem of difficulty-level 'EASY'"
"4. if learner fails in a problem of difficulty-level 'TOUGH', next select
a problem of difficulty-level 'MEDIUM'"
Now given this, I am not sure whether my approach is correct in terms of
tool selection or not? Also, how should I represent the learning materials?
Thanks,
