This study introduces a framework for expert knowledge research and applies concept mapping with Pathfinder scaling in pulmonary physiology education. It assesses how instruction impacts student understanding and its correlation with academic performance.

Area of Science:

  • Medical Education
  • Cognitive Science
  • Physiology

Background:

  • Expert knowledge research requires standardized methodologies.
  • Concept mapping is a valuable tool for visualizing understanding.
  • Previous research has not fully explored indirect methods like Pathfinder scaling for expert knowledge representation.

Purpose of the Study:

  • To present a framework for conducting and reporting expert knowledge research.
  • To detail concept mapping studies using Pathfinder scaling in pulmonary physiology.
  • To evaluate the impact of educational interventions on student concept maps and their relation to performance.

Main Methods:

  • Developed a framework contrasting direct and indirect approaches to expert knowledge research.
  • Conducted three concept mapping studies in pulmonary physiology using Pathfinder scaling.

  • Analyzed changes in student concept maps post-instruction and correlated map similarity with exam scores.

    • Main Results:

    • Demonstrated the utility of Pathfinder scaling for deriving expert concept maps.
    • Quantified changes in student understanding of pulmonary physiology concepts after instruction.
    • Found a correlation between student-instructor concept map similarity and student academic performance.

    Conclusions:

    • The presented framework offers a structured approach to expert knowledge research.
    • Concept mapping with Pathfinder scaling is effective for assessing learning in pulmonary physiology.
    • Further research is needed to refine concept mapping techniques in health sciences education.
