Summary

An intelligent tutoring system (ITS) uses computing technologies to provide learners with instruction and feedback tailored to their needs. This lesson introduces the purpose of ITSs and traces their development from mechanical teaching machines to early computer-based tutors.

An intelligent tutoring system is a computer system designed to imitate some functions of a human tutor. It can present instruction, respond to learner actions, and provide immediate, customized feedback, often without requiring a teacher to intervene at every step.

All flashcards

What is an intelligent tutoring system (ITS)?
A computer system that models aspects of tutoring and adapts instruction or feedback to the learner.
What did Pressey's 1924 teaching machine do?
It presented questions, accepted learner responses through keys, and recorded scores.
How did Skinner's teaching machine use behaviorist ideas?
It encouraged learners to construct answers and rewarded correct responses.
What was computer-assisted instruction (CAI)?
Computer-delivered instruction, often using programmed input-output sequences in early systems.
How did ITS differ from much early CAI?
ITS used knowledge about the subject and learner to respond to learner errors.

Quiz questions

  1. Which component of an intelligent tutoring system represents subject concepts, rules, and problem-solving strategies?Answer: The domain model
  2. What does the student model in an intelligent tutoring system estimate?Answer: The learner's knowledge and, in some systems, cognitive or affective state
  3. What is the primary role of the tutoring model in an intelligent tutoring system?Answer: It selects instructional actions using information about the subject and learner.
  4. How does constraint-based modelling assess a learner's solution?Answer: It checks which solution constraints are satisfied or violated.
  5. What is GIFT in the context of intelligent tutoring systems?Answer: An open-source, domain-independent framework for building tutoring systems
