Area of Science:

  • Educational Technology
  • Chemistry Education
  • Artificial Intelligence in Education

Background:

  • Computer-assisted learning in chemistry has evolved with various systems like virtual environments.
  • Developing effective systems requires robust knowledge representation, student interfaces, and adaptive learning processes.

Purpose of the Study:

  • To explore computerized dialogue systems for simulating teacher-student interaction in chemistry education.
  • To propose an ontology for characterizing this interaction using an object-oriented paradigm.

Main Methods:

  • Developed a knowledge model using multiconnected frames (chunks) with varying complexity and explanatory models.
  • Implemented an object-oriented approach to model knowledge and student understanding.
  • Created a Java-based explanatory system for student-dominated dialogues.
