Pedagogical Strategies for Human and Computer Tutoring.
Reiser, Brian J.
The pedagogical strategies of human tutors in problem solving domains are described and the possibility of incorporating these techniques into computerized tutors is examined. GIL (Graphical Instruction in LISP), an intelligent tutoring system for LISP programming, is compared to human tutors teaching the same material in order to identify how the intelligent tutoring system achieves the pedagogical goals of human tutors. This comparison shows that model-tracing tutors can provide the immediate feedback and guidance provided by human tutors, such as hints when students are stuck, feedback to help in locating an error, and guidance in repairing an error. Currently, human tutors are more subtle, less direct, and possibly more gentle in this feedback process, but the cognitive and motivational consequences have yet to be explored. Computer tutors are currently limited by a low bandwidth of communication, but many advantages of visual displays are now being explored. Much further research is needed on the issues of the timing and content of feedback, student control, and learning by discovery. Intelligent tutors are now being used as experimental tools with which to explore these issues. (45 references) (GL)
