This study introduces cost-effective methods for intelligent tutoring software (ITS) in K-12 math. It uses cognitive skills, data mining, and webcam-based attention tracking to personalize learning without intrusive technology.

Area of Science:

  • Educational Technology
  • Artificial Intelligence in Education
  • Human-Computer Interaction

Background:

  • Intelligent tutoring software (ITS) offers significant potential for K-12 education.
  • Collecting rich user data in real-world classroom settings is challenging due to limitations of advanced sensing technologies.
  • Existing ITS often lack non-intrusive methods for adapting instruction to individual student needs in public schools.

Purpose of the Study:

  • To develop and evaluate "cheap and cheerful" strategies for gathering user information within an ITS for high school mathematics.
  • To enable personalized, real-time adaptation of instructional content delivery in resource-constrained educational environments.
  • To create non-intrusive software that responds to student cognitive abilities, motivation, and attention.

Main Methods:

  • Assessing student cognitive skills: abstract reasoning, math facts, computational skill, and spatial ability.
  • Employing data mining and machine learning to identify effective instructional patterns from historical student data.
  • Integrating a low-cost, focus-of-attention tracking system using web cameras to monitor student engagement.

Main Results:

  • Demonstrated feasibility of using cognitive assessments and machine learning for personalized ITS.
  • Showcased the utility of coarse-grained attention tracking for timing multimedia content delivery.
  • Identified potential for diagnosing problem-solving errors based on attention patterns.

Conclusions:

  • The proposed "cheap and cheerful" strategies provide a viable approach for enhancing ITS in public K-12 settings.
  • Combining cognitive modeling, data mining, and basic attention tracking allows for adaptive instruction without expensive hardware.
  • This research paves the way for more accessible and effective intelligent tutoring systems tailored to individual learners.
